ELECTRONIC LOCK SYSTEM WITH MOTION DETECTION

Technical Field

The present invention relates to an electronic lock system having a sensor module for providing controlled access through a doorway having a door mounted to 5 a door frame. It also relates particularly but not exclusively to the electronic lock 2022201999

system being remotely configurable by a user. The present invention also relates to a method for providing controlled access through a doorway using the sensor module.

Background of Invention

The commercial security market is generally supplied with mechanical, 10 electromechanical and electronic locks. The locks are often installed with hard wiring and utilise powered actuators to release an electronic strike or magnetic lock. These locks are usually keyless, controlled without a mechanical key, and are operated using a keypad, magnetic or electronic access card, or fob and more recently, may include biometric scanners to provide a personal digital signature. While egress from 15 the inside to the outside is generally achieved by depressing a release button or the like on the inside of the door, these locks may be monitored by a security system, often with personal security guards adding an extra layer of security.

Electronic door locks may be provided with a wide variety of electronic components. The components may include actuators, such as motors, solenoids 20 linear drivers and the like which operate electrically and allow the lock to be remotely locked or unlocked. Electronic door locks also often include one or more sensors positioned within the lock to detect and signal the position of various lock components, such as a latchbolt or deadbolt if included, the locked or unlocked status of the lock, and the position of the door relative to the door frame (door open or 25 closed), to name a few. The electronic door lock may also be provided with other kinds of auxiliary electronic components, such as microcontrollers and memory, for operation.

Electronic door locks may also include sensors for detecting the motion of an object, such as a person, animal or vehicle, near the doorway. Electronic door 30 locks currently available may optionally include or be used in conjunction with a

passive infrared (PIR) sensor for detecting motion of an object near the doorway. PIR sensors are used to measure infrared (IR) light radiating from moving objects that emit heat. The detection of motion using the PIR sensor may trigger locking or unlocking of the door.

5 A disadvantage of PIR sensors is that they are unable to detect the direction of an object moving relative to the doorway. For example, the door may be 2022201999

inadvertently unlocked when a person is walking along or parallel to the doorway instead of requiring access through the door or doorway. Thus, PIR sensors may more often result in false triggers of locking or unlocking of the door.

10 Another disadvantage of PIR sensors is that they require manual adjustment for the sensor settings. For example, the angle of the PIR sensor is usually adjusted by manually tilting the sensor once the lock has been installed on the door or door frame. This requires an installer or user to climb up and down ladders to physically reach the door lock, usually mounted at the top of the door or door frame, 15 to change the sensor angle. Similarly, other sensor settings are often controlled by a push button on the door lock housing. This requires the installer or user to physically touch the push button on the installed door lock at a height and navigate a complex menu structure usually with a single push button.

It would be desirable to provide an electronic lock system which 20 ameliorates and/or overcomes one or more problems or inconveniences of the prior art.

A reference herein to a patent document or any other matter identified as prior art, is not to be taken as an admission that the document or other matter was known or that the information it contains was part of the common general knowledge 25 as at the priority date of any of the provisional claims.

[0054] It is to be appreciated that embodiments of the invention are not limited to use with electromagnetic locks. The electronic lock system may include any kind of 5 electronic lock with an electronic mechanism for opening or closing a door as known to a person skilled in the art. For example, electronic door strikes may be used which secure latch bar doors. The latch mechanism operates based on application of an electric current to either lock or release the latch. Alternatively, electronic bolt locks may be used, which again operate using an electronic system. The electronic lock 10 system may also include an electronic keypad lock requiring a numerical code or password in order to unlock the door. Other forms of electronic locks are known including Radio Frequency Identification (RFID) locks which use a radio frequency device that carries the signal to unlock doors, Bluetooth electronic locks which use Bluetooth to control access to the door, or even biometric equipment such as 15 fingerprint or retinal scans to provide access through a doorway to unlock the mechanism.

[0055] Figures 1 to 9 illustrate preferred embodiments of the invention relating to an electronic lock system 100 for providing controlled access through a doorway 500 having a door 520 mounted to a door frame 510. The system 100 includes an 20 electronic 20 electronic lock200 lock 200mounted mounted to the to the door door 520520 or or thethe door door frame frame 510. 510. TheThe electronic electronic

The system 100 also includes a sensor module 300 which includes a first sensor 310 for generating a detection beam in a detection zone for traversal along a path remote from the sensor 25 module 300 and receiving reflected energy of the detection beam. The sensor module 300 also includes a processor 320 for processing a reflected energy signal from the first sensor 310 to detect the presence of an object 600 in the detection zone. The system 100 also includes a controller 240 in electronic communication with the sensor module 300. The controller 240 is configured to wirelessly receive one or more 30 parameters for defining the detection zone of the sensor module 300. The system 100 is configured to disable the electronic mechanism such that the door 520 is in an unlocked state for a pre-defined time interval upon detection of the presence of the object 600 in the detection zone.

When disabled, the electronic mechanism is configured to disengage with the other of the door 520 or the door frame 510 when the electronic lock 200 is in an unlocked 5 state. The operation of the electronic lock 200 and different modes of operation will be described in more detail below and in relation to Figures 13A-B.

[0057] Figure 1A illustrates a perspective view of a doorway 500 having a door 520 mounted to a door frame 510, and showing an electronic lock system 100 mounted on the doorway 500, according to some embodiments of the invention. The 10 door frame 510 is partially cut-away for viewing components of the electronic lock system 100. Figure 1B shows an enlarged view of the electronic lock system 100 of Figure 1A. The door 520 is in an open position and unlocked state in Figures 1A and 1B. 1B.

[0058] The electronic lock system 100 includes a housing 110 which is mounted 15 or affixed to the door frame 510 via a mounting bracket 112 (see also Figures 2 and 3).

The electronic lock 200 may include one or more electromagnets 111 which are energizable via one or more electromagnetic coils 210 (see also Figures 2 to 8). The electronic lock system 100 also includes a mounting 20 bracket 120 for mounting an armature plate 130 to the door 520. When an electric current is delivered to the electromagnetic coils 210, the electromagnets 111 are energized such that there is attraction to the armature plate 130, thereby maintaining the door 520 in a closed position and locked state. Removal of the electric current disables the locking mechanism such that the door 520 can be opened in an unlocked 25 state. 25 state.

[0059] Figures 2 and 3 illustrate exploded views of components of the electronic lock system 100, according to some embodiments of the invention. Firstly, the housing 110 includes the electronic lock 200 and is mountable to the door frame 510 via the mounting bracket 112. The mounting bracket 112 may be secured or affixed to 30 the housing 110 by one or more fasteners, such as screws 150 as shown.

The electromagnet housing 113 may be secured within the housing 110 using one or more fasteners, such as screws 146 as shown in Figure 3. The 5 electromagnet housing 113 may include three electromagnets 111 as shown, with associated electromagnetic coils 210 (see Figure 8). Although three electromagnets 111 are depicted, it would be understood that the electronic lock 200 may only include one electromagnet 111, or may include two or more than three electromagnets 111 as suitable for the use of the lock system 100.

10 [0061] The PCB housing 118 may include a main PCB 230 including electronic components for operation of the electronic lock 200. The various components will be described in more detail in relation to Figure 8.

The main PCB 230 is couplable with the electromagnetic coils 210 of the 15 electromagnetic housing 113 via an electromagnet connector 232. The main PCB 230 is also couplable with a main connector 236 as shown in Figures 2 to 6, for providing external power to the electronic lock 200 and/or communication between the electronic lock 200 and an access control system 400 (see also Figure 8). The electronic lock 200 may include a cover plate 114 and backing plate 115 for securing 20 the main PCB 230 within the PCB housing 118. The cover plate 114 and backing plate 115 may be secured to the PCB housing 118 using one or more fasteners, for example, via screws 142 as shown.

[0062] The sensor module 300 may be adapted to be located adjacent to the electronic lock 200 mounted to the door frame 510 (or to the door 520 depending on 25 the arrangement of the lock system 100). Thus, the sensor module 300 and electronic lock 200 may be mounted to the same door 520 or door frame 510. The sensor module 300 may be adapted to be located within the housing 110 mounted to the door frame 510, also including the electronic lock 200, thus being integrated with the electronic lock 200.

30 [0063] The electronic lock system 100 may further include a sensor module housing 117 for housing the sensor module 300. The sensor module housing 117 may be adapted to engage with the housing 110 including the electronic lock 200.

13

The sensor module housing 117 may be adapted to be mounted within the housing 110 or mounted to the housing 110. In some embodiments, the sensor module housing 117 maybe secured or affixed to the housing 110 using one or more fasteners, for example, via screws 144 as shown in Figure 2. A sensor module cover 5 116 is also couplable with the sensor module housing 117, such as through sliding engagement over the sensor module housing 117. The sensor module cover 116 may include a transparent portion 119 to enable operation of one or more motion detector sensors 310 through the sensor module cover 116 (see also Figure 6).

[0064] Figures 4 to 6 illustrate cut-away end views of the electronic lock system 10 100 showing the electronic lock components and sensor module 300 housed in the sensor module housing 117. The sensor module housing 117 includes the sensor module 300 having a PCB, which is couplable with the main PCB 230 of the electronic lock 200. The components of the sensor module 300 will be described in more detail in relation to Figure 9. Figure 6 shows some more detail of the main PCB 15 230230 15 andand the the sensor sensor module module 300 with 300 with and motion PCBmotion PCB and detector detector sensors sensors 310. 310. There There are four motion detector sensors 310 shown, although the sensor module 300 may only include a single motion detector sensor 310 as illustrated in Figure 9, or any number of sensors, such as also including sensor 320, as would be appreciated by a person skilled in the art. The main PCB 230 may also include one or more indicator 20 lights 258, which may include light-emitting diodes (LEDs) as shown in Figure 6. The main PCB 230 may include two indicator lights 258, which are RGB LEDs and may utilise a range of colours to provide an indication of the state of the lock, e.g., an unlocked state (green) and a locked state (red) as also shown in Figure 8. The emitted light from the LEDs 258 may pass through a diffuser 152 and a window 154 of 25 the housing 110 as shown in Figure 6.

[0065] Figures 7A and 7B illustrate perspective views of a doorway 500 having a door 520 mounted to a door frame 510, and showing the electronic lock system 100 mounted with a complete door frame 510, according to some embodiments of the invention. In the embodiments described herein, the sensor module 300 and the 30 housing 110 including the electronic lock 200 are mounted to the door frame 510, and the armature plate 130 is mounted to the door 520. It is possible for the electronic lock system 100 to operate in another configuration in which the electronic lock 200 and sensor module 300 are located on the door 520 and the armature plate 130 is located

14

on the door frame 510. Thus, all of the features of the electronic lock system 100 described herein may also be applicable to this alternative configuration as would be appreciated by a person skilled in the art.

[0066] Figure 8 illustrates a detailed schematic diagram showing electronic 5 components in an electronic lock system 100, according to some embodiments of the invention. An electronic lock 200 is shown, which includes electromagnet coils 210, a sensors PCB 220 and a main PCB 230. As previously mentioned, the electromagnet coils 210 are located within the electromagnet housing 113 (which may also include a PCB not shown) and coupled with the main PCB 230 via an electromagnet connector 10 232. The sensors PCB 220 may also be housed within the electromagnet housing 113 (not shown). The main PCB 230 includes a microcontroller 240 which is configured to receive a number of inputs and provide various outputs as shown.

[0067] Although a microcontroller 240 is referred to the embodiments described herein, it is possible that the electronic lock system 100 may include any form of 15 controller, and not specifically a microcontroller 240. In some embodiments, the controller may not be located within the main PCB 230 or electronic lock 200 itself (not shown). The controller may be connected with the main PCB 230 for receiving signals from the electronic components and delivering various signals to the electronic components as indicated in Figure 8.

20 [0068] The sensors PCB 220 may include a door position sensor 222 and a bond sense sensor 224 as illustrated. The door position sensor 222 may be a reed switch embedded in the electromagnet housing 113 (not shown). A small magnet may be located in the armature plate 130 to trigger an open or closed signal when the armature plate 130 is applied to the electromagnet(s) 111 and aligned with the 25 location of the reed switch. The door position output is delivered via the electromagnetic connector 232 to a microcontroller 240, optionally via a H-bridge driver 242 as required. The door position output will operate regardless of power being applied to the electromagnet(s) 111 or not as the signal is not processed by the main PCB 230.

30 [0069] The bond sense sensor 224 allows a relay output to be triggered indicating a change of state if the electromagnet(s) 111 are bonded to the armature plate 130

(locked state) or not bonded (unlocked state). The bond sensor processing is performed through a PCB in the electromagnet housing 113 (not shown). Thus, the 2022201999 23 Mar

bond sensor 224 will only operate when the electromagnet housing 113 is powered.

[0070] The main PCB 230 may include a PCB antenna 250 with associated 5 Bluetooth RF circuitry 252, through which signals may be delivered to or from the microcontroller 240. In this way, the microcontroller 240 may be configured to wirelessly receive one or more parameters for defining the detection zone of the sensor module 300. The microcontroller 240 may receive the signals via an external device 700, such as illustrated in Figure 18. The external device 700 may be a mobile 10 device having installed thereon a software application for configuring settings of the lock system 100.

[0071] The microcontroller 240 and external device 700 may communicate using a BLE (Bluetooth Low Energy) communication protocol, which is desirable for short range communication. Although the use of Bluetooth is illustrated and described 15 herein, a person skilled in the art would appreciate that other wireless forms of communication are possible to enable transfer of information between an external device and the electronic lock 200. For example, the wireless communication may be performed via Wi-Fi networks such as WLAN, Zigbee wireless technology, satellite communication, mobile cellular networks including 3G, 4G or 5G, Global Positioning 20 System (GPS) technology and the like.

[0072] The microcontroller 240 is in electronic communication with the sensor module 300 via a motion detector connector 234 (see also Figure 9). Thus, the one or more parameters for defining the detection zone received at the microcontroller 240, may be communicated to the sensor module 300 for use in defining the detection 25 25 zone zone of the of the firstsensor first sensor310. 310.Various Variousinformation information is is transferred transferred between the main between the PCB main PCB

230 and sensor module 300 via an 12C bus line. The bolded lines of Figures 8 and 9 indicate the indicate the I2C 12Cbus busline linewhich which enables enables communication communication of the microcontroller of the microcontroller 240 with 240 with the EEPROM memory 246 and LED driver 260 on the main PCB 230, and communicationbetween communication between thethe microcontroller240 microcontroller 240and and themicrocontroller the microcontroller312 312ofofthe the 30 sensor 30 sensor module module 300 the 300 via via the mainmain connector connector 330 motion 330 and and motion detector detector connector connector 234. 234.

16

[0073] The microcontroller 240 may also receive input via a USB connector 264. The USB connector 264 may be a mini or micro USB interface to enable firmware changes on the main PCB 230. The microcontroller 240 is not directly coupled to the USB connector 264. Instead, power is delivered through a linear voltage regulator 262 such that the voltage is delivered around 5VDC for powering the USB connector 264. The main PCB 240 also includes a programming connector 248 for enabling firmware changes, such as through wired connection with an external device, and the changes are communicated via the microcontroller 240.

[0074] Configuration of the electronic lock system 100 may also be provided through a configuration push button 244. This may be manually depressible by a user or installer for configuration of the lock settings. The push button 244 may allow access to a configuration menu with a number of features/functions being selectable through an on-board menu structure. The options for configuration will be discussed in more detail below. The configuration of the electronic lock system 100 may also be provided wirelessly to the microcontroller 240 via the PCB antenna 250 and Bluetooth RF circuitry 252, such as through an external device 700. This will also be discussed in more detail with reference to the software application as illustrated in Figures 19A J.

[0075] The main PCB 240 also includes a memory device 246 which is an EEPROM memory. Although the memory device 246 is shown as an EEPROM memory, it may include other types of non-volatile memory devices, such as internal flash memory, internal FRAM memory, or external flash memory, as would be appreciated by a person skilled in the art.

[0076] The memory device 246 may be in electronic communication with the microcontroller 240 for storage of the one or more parameters for defining the detection zone received wirelessly via Bluetooth. The memory device 246 may also store other information relating to configuration of the sensor module 300. The memory device 246 may store values for a pre-defined threshold value or range of values derived from the one or more parameters defining the detection zone. For example, the memory device 246 may store the look-up table as shown in Figure 17. The pre-stored values and look-up table may be periodically updated through firmware updates to the electronic lock 200. The memory device 246 may also store a

17

pre-defined threshold value or range of values derived from normative data representing one or more physical characteristics of a person. For example, the physical characteristics may include at least one dimension and/or shape of a typical or average person's body, such as the person's height and eye level. This data may 5 be accessible by the processor 320 of the sensor module 300 via the 12C bus line for detecting the presence and/or motion of an object in the detection zone.

[0077] The main PCB 240 also includes a speaker 254 and speaker drive 256 which are connected to the microcontroller 240. The speaker 254 may include an integrated buzzer/sounder and provide sound output including a steady or pulsed 10 buzzer. Optionally, the speaker 254 may provide sound output including an audible message, such as a voice message with instructions, warnings and/or a selection of options for the user, installer or an object 600, such as a person, animal or vehicle, near the doorway 500. The microcontroller 240 may activate the speaker 254 at step 932 in the flow chart of Figure 13A based on received signals at the microcontroller 15 240, e.g., signals identifying a new event including the presence or motion of an object 600.

[0078] Furthermore, the main PCB 240 may also include 2 RGB LEDs 258 with an associated LED driver 260 which is connected with the microcontroller 240. The LEDs may be used to indicate when the door is in a locked state, for example with a red 20 light LED, and in an unlocked state, for example with a green light LED. However, the LEDs may be configured to operate with various colour lights for indicating state of the electronic lock 200, as would be appreciated by a person skilled in the art. The LEDs 258 may also be configured to flash for a pre-defined time period based on powering and bonding of the electromagnet 111 with the armature plate 130, 25 depending on the mode of operation. This will be discussed in more detail below, with regards to various modes of operation of the lock system 100.

[0079] The electronic lock 200 may also be optionally connected with an access control system 400 as shown in Figure 8. More specifically, the main PCB 230 may be connected with the optional access control system 400 via a main connector 236. 30 As shown, the main connector 236 is then connected with the electromagnet connector 232, the microcontroller 240 (via a power circuit protection 268 and step-

18

down power converter 266 to alter the voltage), and to a motion detector relay 270 and bond sense relay 272.

[0080] In some modes of operation, which will be described with reference to Figures 13A-B, the lock system 100 is configured such that the access control system 5 400 releases power to the electromagnet 111 directly instead of via the microcontroller 240. This is achieved by output signals from the motion detector relay 270 and bond sense relay 272 being deliverable to the access control system 400. The access control system 400 may be a security system which couples a number of lock systems 100 together, such as in a commercial building, and provide monitored 10 control over the systems 100 for security. The access control system 400 may also be a safety system, such as a fire safety system connecting doors in a building which each have a lock system 100. The access control system 400 may not be a wired system as shown but instead operate as a network which wirelessly communicates with each of the lock systems 100 installed, such as via Wi-Fi connection or through 15 the PCB antenna 250 and Bluetooth RF circuitry 252 (not shown). Additionally/alternatively, the access control system 400 may control operation of the lock systems 100 via cloud-based networking.

[0081] Figure 9 illustrates a schematic diagram showing components in a sensor module 300 according to some embodiments of the invention. The sensor module 20 300 may be housed separately or together with the electronic lock 200 as previously described. In some embodiments, the sensor module 300 is integrated with the electronic lock 200 and located within a common housing 110. The sensor module 300 is electrically connected to the electronic lock 200, and more specifically, to the microcontroller 240 of the main PCB 230. The sensor module 300 may include a main 25 connector 330 which is couplable with the motion detector connector 234 on the main PCB 230 via the 12C bus line. The main connector 330 may be electronically connected with the microcontroller 312 and a processor 320, and also with a first sensor 310 as illustrated, and optionally, a second sensor 380.

[0082] The first sensor 310 is configured to generate a detection beam in a 30 detection zone for traversal along a path remote from the sensor module 300. This is illustrated in Figure 9 where a detection beam is directed towards the object 600 from the first sensor 310. The first sensor 310 then receives reflected energy of the

19

detection beam from the object 600. In order to provide the detection beam and receive the reflected energy, the first sensor 310 and/or sensor module 300 may include an antenna having a transmitter and receiver (not shown), as would be appreciated by a person skilled in the art.

5 [0083] The first sensor 310 may be a microwave sensor. Preferably, the first sensor 310 is a radar sensor. The radar sensor may be a doppler radar, which may use the Doppler effect to produce velocity data of the object 600 in the detection zone. The first sensor 310 may operate at a frequency of around 24 GHz, however higher frequency sensors may be used, such around 60 or 70 GHz in order to 10 increase the sensitivity.

[0084] Microwave and radar sensors have not been used before in conjunction with electronic locks 200 that are known to the Applicant. Moreover, microwave or radar sensors have not been used more specifically in conjunction with electromagnetic locks 200. In contrast, electronic door locks currently available may 15 optionally include, or be used in conjunction with, an infrared sensor, and particularly, a passive infrared (PIR) sensor. It is advantageous for electronic door locks to instead employ microwave or radar sensors as these allow for detection of the direction of an object 600 moving relative to the doorway 500. This process will be described with reference to the flow charts of Figures 15A-B. This enables a reduction in false 20 triggers of locking or unlocking of the door 520 as inadvertent movement of the object 600 along or parallel to the doorway 500 will not trigger the lock. Only intentional movement of the object 600 towards the doorway 500 for access through the door 520 or doorway 500 will be detected and trigger the unlocking mechanism.

[0085] Where the first sensor 310 is a microwave or radar sensor, the first sensor 25 310 may generate radio-frequency (RF) energy at various frequencies, such as around 24 GHz or higher, which is transmitted in a detection zone away from the sensor module 300 installed on the door 520 or door frame 510. When an object 600 is present in the detection zone, RF energy is reflected back along a path towards the first sensor 310/sensor module 300 and received as an echo. Although the use of RF 30 is described herein, a person skilled in the art would appreciate that the first sensor 310 may operate using other similar technologies involving transmittal of a detection beam and receipt of reflected energy, such as ultrasound or sonar, for example.

20

[0086] The sensor module 300 provides for two sampling channels as shown in Figure 9. The two channels include analog-to-digital converters (ADC) and the output signals are then amplified through respective amplifiers including a Q-Amp 340 and I Amp 350. Although these specific amplifier types are mentioned, it would be 5 appreciated that various amplifiers may be used as appropriate to amplify the reflected energy signals. The amplified signals are then delivered to a processor 320 in a microcontroller 312. In some embodiments (not shown), only a processor 320 is included without a microcontroller 312. For example, a general controller may be used to operate both of the electronic lock 200 and sensor module 300 as previously 10 described. The processor 320 is configured to process the reflected and amplified energy signals in order to detect the presence of an object 600 in the detection zone, and more specifically, may detect motion of the object 600. The process for this detection and steps performed by the processor 320 will be discussed further in relation to Figures 15A-B.

15 [0087] The sensor module 300 may also optionally include a second sensor 380 as indicated by the broken lines in Figure 9. The second sensor 380 may be an infrared sensor. More specifically, the second sensor 380 may be a passive infrared (PIR) sensor). The second sensor 380 may be configured to detect radiant energy temperature changes in the detection zone remote from the sensor module 300, such 20 as due to an object 600 being present in the detection zone. The processor 320 may process data from the second sensor 380 to detect changes in radiant energy associated with the presence of the object 600 in the detection zone. For example, the processor 320 may detect the presence of a person, animal and/or vehicle to name a few, which emit thermal energy. Furthermore, the processor 320 may be 25 configured to distinguish between a person, animal or vehicles based on, for example, comparison of the magnitude of the energy signal with typical values or ranges of values based on normative data representing identifiable characteristics of people, animals or particular vehicles, such as cars, trucks or motorbikes.

[0088] Figure 9 also shows that the sensor module 300 includes two RBG LEDs 30 360, 370 according to some embodiments. The LED 360 may operate using a green light and the LED 370 may operate using a red light. The LED 360 may operate when the door 520 is closed and secured displaying the green light, and switch to the LED 370 when the door 520 is unlocked and can be opened displaying the red light. It is

21

also possible to disable the LED operation as desired by a user. The LEDs 370, 370 may be configured to operate with various colour lights, as would be appreciated by a person skilled in the art.

[0089] In another preferred embodiment, a sensor module 300 is provided for use 5 with an electronic lock system 100 for providing controlled access through a doorway 500 having a door 520 mounted to a door frame 510. The system 100 includes an electronic lock 200 adapted to be mounted to the door 520 or the door frame 510. The electronic lock 200 includes an electronic mechanism for engagement with the other of the door 520 or the door frame 510 when the door 520 is in a locked state. The 10 system 100 also includes a controller 240 configured to wirelessly receive one or more parameters for defining a detection zone of the sensor module 320. The sensor module 300 is in electronic communication with the controller 240. The sensor module 300 includes a first sensor 310 for generating a detection beam in a detection zone for traversal along a path remote from the sensor module 300 and receiving reflected 15 energy of the detection beam. The sensor module 300 also includes a processor 320 for processing a reflected energy signal from the first sensor 310 to detect the presence of an object 600 in the detection zone. The system 100 is configured to disable the electronic mechanism such that the door 520 is in an unlocked state for a pre-defined time interval upon detection of the presence of the object 600 in the 20 detection 20 detectionzone. zone.

[0090] As indicated by the same reference numerals employed, the sensor module 300 and lock system 100 may have one or more features described in relation to the embodiments of Figures 1 to 9. In particular, the sensor module 300 of this embodiment may be configured for use with an electronic lock system 100. Thus, the 25 sensor module 300 may not be found in a common housing component of the electronic lock system 100, such as housing 110. The sensor module 300 may be connectable with the lock system 100, particularly at the main PCB 230 of the electronic lock 200 as shown in Figure 8, but remain a separate component not be integrated into the lock system 100. Thus, the sensor module 300 may be adapted to 30 be located adjacent to the electronic lock 200 mounted to the door 520 or door frame 510. The sensor module 300 may include its own housing 117 as previously described, which is adapted to be mounted adjacent to the electronic lock 200 or engage with the housing 110 of the electronic lock 200.

22

[0091] Figures 10 to 16 illustrate preferred embodiments of the invention relating to a method 800 for controlling access through a doorway 500 having a door 520 mounted to a door frame 510. Various steps of the method may be performed by the microcontroller 240 of the electronic lock 200, or the processor 320 of the sensor 5 module 300, as will be described.

[0092] Figure 10 illustrates that the method 800 includes the step 810 of providing an electronic lock system 100 including an electronic lock 200 adapted to be mounted to the to the door 520ororthe door 520 thedoor door frame frame 510.510. The electronic The electronic lockincludes lock 200 200 includes an electronic an electronic

The system 100 also includes a sensor module 300 including a first sensor 310 and a processor 320, and a controller 240 in electronic communication electronic with the communication with the sensor module300. sensor module 300.The Themethod method 800800 also also includes includes

the step 820 of wirelessly receiving, using the controller, one or more parameters for defining a detection zone of the sensor module 300. The method 800 also includes 15 the step 830 of generating, using the first sensor 310, a detection beam in a detection zone for traversal along a path remote from the sensor module 300 and receiving reflected energy of the detection beam. The method 800 also includes the step 840 of processing, using the processor 320, a reflected energy signal from the first sensor 310 to detect the presence of an object 600 in the detection zone. Finally, the method 20 800 includes the step 850 of disabling, using the system, the electronic mechanism such that the door 520 is in an unlocked state for a pre-defined time interval upon detection of the presence of the object 600 in the detection zone.

[0093] Figure 12 illustrates further steps in method 800 relating to initial setup of the lock system 100. The steps are performed by the microcontroller 240 of the lock 25 system 100. At step 902, the microcontroller 240 initially configures the hardware components of the electronic lock system 100. This includes the step 904 of reading settings from the EEPROM memory 246. The microcontroller 240 then initiates the real-time operating system (RTOS) at step 906, creates the RTOS tasks at step 908 and starts the RTOS scheduler at step 910. At step 912, the microcontroller 240 then 30 starts the Bluetooth Advertising for 60 seconds and begins an infinite loop at step 914.

23

[0094] The RTOS tasks created at step 908 include: Task 1, namely reading the system analog and digital inputs as shown in Figure 12, Task 2, namely checking system events as shown in Figures 13A-B and Task 3, namely handling the Bluetooth connection as shown in Figure 14. Each of the three tasks will now be described in 55 more more detail. detail.

[0095] Figure 12 illustrates Task 1 which includes the microcontroller 240 reading the system analog and digital inputs. This includes the step 916 of starting the analog to-digital conversion (ADC), the step 918 of reading digital inputs and the step 920 of providing a 15 milliseconds delay. The step 918 may include accessing the control 10 speaker input of the speaker 254 via the speaker driver 256 and also accessing the configuration push button 244. When the ADC is finished at step 916, the microcontroller 240 then reads the analog values, which includes the Bond Sense Sensor 224 and main power voltage, at step 922. The controller signal is then sent to Task 2 at step 924. The process for motion detection will be described in more detail, 15 however when the sensor or motion detector module 300 detects presence or motion of an object 600, the method also includes sending the motion detector signal to Task 2 at step 926.

[0096] Figure 13A-B illustrates Task 2 which includes the microcontroller 240 checking the system events. At step 928, the microcontroller 240 checks if a new 20 event has been received. If no event has been received, Task 2 is restarted. If an event is received, the microcontroller 240 then checks the received signals at step 930, which include a speaker signal, a controller signal and a motion detector signal. The speaker signal is checked and the microcontroller 240 may turn on the speaker 254 at step 932. This may include operating the speaker 254 to provide a buzzer or 25 audible notification, and/or possibly voice instructions or warnings to a user or object 600 near the doorway 500.

[0097] The microcontroller 240 also checks the motion detector signal at step 930. This leads onto the method steps as shown in Figure 13B. The microcontroller 240 may check the operating mode of the lock system 100 at step 954. The operating 30 mode may include one of three options: a disabled mode, a standalone and an integrated mode.

24 Mar 2022

[0098] In the disabled mode, the sensor module 300 is inoperable. Thus, the MDM-Disable signal is sent to the beginning of Task 2 as indicated in Figure 13A. The microcontroller 240 then performs the step 934 as shown in Figure 13A to check the

2022201999 23 operating mode of the lock system 100. If the mode is either disabled or integrated, 5 the microcontroller 240 then performs the step 936 of checking if the main power voltage is zero. If the voltage is zero, then the microcontroller performs the step 938 of turning off the coils 210 such that the door lock 200 is in an unlocked state, where the door 520 is able to be opened. If the main power voltage is not zero, then the microcontroller 240 performs the step 940 of checking the level of the voltage. If the 10 input voltage is 12V, the microcontroller 240 performs the step 944 of turning on the coils 210 in the 12V mode such that the door lock 200 is in the locked state, where the door 520 in unable to be opened. If the input voltage is 24V, the microcontroller 240 performs the step 942 of turning on the coils 210 in the 24V mode, where the door lock 200 is in the locked state and the door 520 is unable to be opened.

15 [0099] In the standalone mode, the sensor module 300 is operable in conjunction with the microcontroller 240 for disabling the electronic mechanism of the electronic lock 200 for a pre-defined time interval. Returning to Figure 13B, the microcontroller 240 sets the motion detection flag at 956 to check if the presence or motion of an object 600 is detected (see steps in Figures 15A and 15B). If the presence or motion 20 of an object 600 is detected, step 958 is performed in which the microcontroller 240 disables the electronic lock 200 by turning off the coils 210 such that the door lock 200 is in the unlocked state. The microcontroller 240 may then perform the step 960 of turning on a timer for either 5 seconds or 30 seconds. A skilled person would appreciate that any time interval may programmed, such as between 5 to 30 seconds, 25 or other desired time interval to leave the door 520 in the unlocked state. When the time period is finished, the step 964 is performed to reset the motion detection flag. Accordingly, the door lock 200 may only be disabled and in the unlocked state for opening of the door 520 for the pre-defined time interval.

[0100] Additionally, in the standalone mode, the microcontroller 240 checks at 30 step 946 if the motion detection flag has been reset, as shown in Figure 13A. If the flag is not reset, then a signal is sent to restart Task 2. Otherwise, if the motion detection flag has been reset, the microcontroller 240 performs the step 948 of checking the level of the main power voltage. If the input voltage is 12V, the

25

microcontroller 240 performs the step 952 of turning on the coils 210 in the 12V mode such that the door lock 200 is in the locked state, where the door 520 in unable to be opened. If the input voltage is 24V, the microcontroller 240 performs the step 950 of turning on the coils 210 in the 24V mode, where the door lock 200 is in the locked state and the door 520 is unable to be opened.

[0101] In the integrated mode, the sensor module 300 is operable in conjunction with an access control system 400 for disabling the electronic mechanism for a pre defined time interval. The microcontroller 240 performs step 962 of setting the motion detection relay 270 as shown in Figure 8. If the presence or motion of an object 600 is detected (see steps in Figures 15A-B), a signal from the sensor module 300 is relayed to the access control system 400 via the main connector 236. The access control system 400 then will operate to determine if the electronic mechanism in the lock 200 should be disabled, such as based on a time delay or network signal. Effectively, the access control system 400 overrides the microcontroller 240 in controlling disabling/enabling of the electronic mechanism in the lock 200 in the integrated mode. The access control system 400 may then perform the steps 936, 938, 940, 942 and 944 as shown in Figure 13A to turn off the coils 210 in the unlocked state, or to turn on the coils 210 in the 12V or 24V modes in the locked state. state.

[0102] The microcontroller 240 is configured to operate the LEDs 258 via the LED driver 260 and/or the speaker 254 in different ways based on the mode of operation of the system 100. In the standalone mode, the electromagnet is powered and bonded to the armature plate 130, and the LED light 258 will indicate red or green (which is user selectable, or various colour lights as desired). When the sensor module 300 detect the presence or motion of an object 600, the microcontroller 240 is configured to release the electromagnet. Once the door 520 is opened, the bond sense sensor 224 will detect that the armature plate 130 is released and the LED lights 258 will fast flash, e.g., 300ms on and 200 ms off, until the door 520 is closed. In the integrated mode, when the access control system 400 removes power to the electromagnet, the electromagnet will be released. At this point, the LED 258 will extinguish due to no power being provided at the electromagnet. When power is re-applied, and if the door 520 is not closed and left open, the LED light will fast flash, e.g., 300ms on and 200

26

ms off. The LEDs 258 may be configured for various operation as desired by the user. It is also possible to disable the LED operation.

[0103] Figure 14 illustrates Task 3 which involves handling of the Bluetooth connection. In Task 3, the microcontroller 240 performs the step 966 of checking if a 5 Bluetooth device is connected with the electronic lock 200. As previously mentioned, the microcontroller 240 may be wirelessly connectable with an external device 700, such as illustrated in Figure 18. The microcontroller 240 and external device 700 may be connected via Bluetooth through an antenna 700 of the external device and the PCB antenna 250 of the electronic lock 200. If a Bluetooth device is not connected, a 10 signal is sent to restart Task 3. If a Bluetooth device is connected, the microcontroller 240 performs the step 968 of processing received commands from the external device 700. In particular, the microcontroller 240 is configured to wirelessly receive one or more parameters for defining the detection zone of the sensor module 300. The one or more parameters may be provided by the external device 700. 15 Furthermore, the external device 700 may provide commands in relation to configuration of the lock system 100, such as the mode of operation. This will be described in more detail in relation to Figure 18 and the software application shown in Figure 19A-J. The microcontroller 240 then performs the step 970 of updating the settings based on the commands provided by the external device 700, and the 20 settings are saved in the EEPROM memory 246 at step 972.

[0104] Figures 15A-B illustrate a flow chart with further steps in the method relating to operation of the sensor module 300 to detect the presence and/or motion of an object 600, and disabling the electronic lock 200 for the pre-defined time interval. The steps are performed by the processor 320 of the sensor module 300. 25 Initially, the processor 320 at step 974 configures the hardware of the sensor module 300, including the 12C bus, Timer, ADC and UART bus.

[0105] The processor 320 then performs the step 976 of reading the sensor settings from the EEPROM memory 246. The sensor settings include one or more parameters for defining the detection zone of the first sensor 310. The one or more 30 parameters may include a dimension of the door 520 or door frame 510 on which the housing 110 is mounted, and/or a distance from the door 520 or door frame 510 for detection of the object 600. As shown at step 976, two parameters may be provided,

27 which include a motion detection range and height. The motion detection range may be the be the desired desireddistance distance from from the the doordoor 520door 520 or or door frame frame 510 for510 for detection detection of the of the object 600. The range may be from about 300mm to about 3500mm. The height may be the actual height or length dimension of the door 520 or door frame 510. The 5 height may be from about 2100mm to about 3000mm.

[0106] Once the settings are read, the processor 320 then activates the first sensor 310 to generate a detection beam in the detection zone, e.g., based on the motion detection range and height, for traversal along a path remote from the sensor module 300 and receives reflected energy of the detection beam. The processor 230 10 then processes the received reflected energy signal by firstly performing the step 978 of starting the ADC conversion and the reading the amplified sensor signals from the Q-amp 340 and I-amp 350 at step 980. The processor 230 then performs a number of steps to process the amplified reflected energy signal from the first sensor 310 to detect the presence of the object 600 in the detection zone.

15 [0107] The processor 230 performs a first step 982 of calling a signal processing function, which may include a Fast-Fourier Transform (FFT), to convert the signals from the frequency domain (since the first sensor 310 may ideally be microwave or radar sensor generating and receiving RF signals) to the time domain. The signal processing function may then use the transformed time signals to calculate the speed 20 of motion and direction of the object 600 using the amplitude/magnitude of the transformed signals. Although FFT is mentioned, the signal processing function may include other mathematical transforms which enable converts of signal data to the time domain, as would be appreciated by a person skilled in the art.

[0108] Figure 15B shows the continuation of steps in the method of Figure 15A. 25 The processor 320 may analyse the processed signals to then detect the presence of the object 600 in the detection zone. As shown in Figure 15B, the processor 320 performs the step 984 of determining if any motion has been detected. For example, this may include processing the transformed time signals to determine if the object 600, while present in the detection zone, has a non-zero speed over a time period. If 30 no motion is detected, the processor 320 performs the step 994 of providing a time delay for 50 milliseconds and then restarts the ADC conversion at step 978.

28

[0109] If motion is detected, the processor 320 then performs the step 986 of determining if the object 600 is moving towards the first sensor 310 or sensor module 300. That is, the processor 320 is configured to detect motion of the object 600 in a direction towards the doorway 500. The directionality of the motion may be 5 determined by processing the transformed time signals to determine the velocity and/or acceleration of the object 600, such as based on changes in amplitude of the signal over a time period. For example, the first sensor 310 may be a radar doppler sensor which uses the Doppler effect to produce velocity data of the object 600 in the detection zone. In some embodiments, the processor 320 is further configured to 10 determine if the motion of the object 600 is in a direction which is substantially perpendicular to the doorway 500 (not shown). That is, the processor 320 may be configured to determine whether the object's motion is in a direction towards the doorway 500, and in particular towards the door 520 or through the doorway 500. This is in contrast to motion of the object 600 in a substantially parallel direction or along 15 the doorway 500 where the object 600 is not attempting to access the doorway 500. For example, a person may be walking past the doorway 500 and not attempting to open the door 520 or move through the doorway 500. Advantageously, the sensor module 300 with the first sensor 310 may enable not only detection of direction of an object 600, but also the object's direction being intentionally towards the doorway 20 500, which minimises the number of false triggers of unlocking of the door 520.

[0110] When the processor 320 detects motion towards the first sensor 310 (that is towards the doorway 500), the processor 320 is further configured to compare the processed reflected energy signal with a pre-defined threshold value or range of values derived from the one or more parameters defining the detection zone. This 25 step is illustrated in Figure 15B, where the processor 320 performs the step 988 of comparing the reflected signal value with the selected range and height in the motion detector look-up table. An exemplary look-up table is illustrated in Figure 17. The step 988 may include the processor 320 being in electronic communication with a memory device, such as EEPROM memory 246, for accessing pre-stored values of the pre 30 defined threshold value or range of values. The pre-stored values may be provided in a look-up table such as that shown in Figure 17.

[0111] Figure 15A illustrates that the processor 320 performs a step 990 of determining if the signal value for the processed reflected energy signal is within the

29

selected range and height. This may include the step of determining if the reflected energy signal value is greater than the pre-defined threshold value or within the pre defined range of values. To perform this step, the look-up table as illustrated in Figure 17 may be accessed by the processor 320, which automatically determines if the 5 object 600 is in the selected range and height, that is, within the detection zone of the first sensor 310. The selected range and height values in Figure 17 are not representative of actual measurements of the range, e.g., the desired distance of the doorway 500 to the object 600 for detection, or the height, e.g., the door 520 or door frame 510 height. Instead, options 1 to 5 for each of the range and height represent 10 selectable options by a user, which include different ranges of measurements, optionally programmable into the firmware of the lock 200. The values within the cells of the table in this case are representative of threshold values to determine if the processed reflected energy signal value is greater than the threshold value for the selected range and height.

15 [0112] If the signal value is within the selected range and height, the processor 320 then performs the step 992 of setting a digital output pin for 100 milliseconds to interrupt the electronic lock 200 in order to disable the electronic mechanism for a pre-defined time interval of 100 milliseconds. The processor 320 then proceeds to step 994 of providing a time delay for 50 milliseconds and then restarts the ADC 20 conversion at step 978. If the signal value is not within the selected range and height, then the processor 320 proceeds straight to step 994.

[0113] Figure 16 is a flow chart showing additional steps in the method 800 for the processor 230 of the sensor module 300, according to some embodiments. The processor 230 receives commands from the electronic lock 200, and more specifically 25 the microcontroller 240, at step 996. The commands may include at least the one or more parameters wirelessly received by the microcontroller 240 for defining the detection zone of the first sensor 310. The processor 230 performs the step 997 of setting the motion detection range and height values based on the commands provided by the microcontroller 240. Furthermore, the sensor settings may be stored 30 in the EEPROM memory 246 on the main PCB 230.

[0114] In some embodiments, the processor 230 of the sensor module 300 may be further configured to detect the presence and/or motion of a person in the

30 2022

detection zone. That is, the processor 230 may be able to distinguish an object 600 that is a person in contrast to an inanimate object, or even an animal. This may be 2022201999 23 Mar

achieved by the processor 230 being able to access a pre-defined threshold or range of values derived from normative data representing one or more physical 5 characteristics of a person. For example, the physical characteristics may include at least one dimension and/or shape of a person's body. The dimensions may include a person's height or eye level. The normative data may be pre-stored in a memory device such as the memory 246 on the main PCB 230. Alternatively, the normative data may be wirelessly received by the microcontroller 240 such as via Bluetooth with 10 an external device 700.

[0115] In some embodiments, the processor 230 of the sensor module 300 may be further configured to distinguish an object 600 that is a person, animal or vehicle from other inanimate objects. The second sensor 380 may be configured to detect radiant energy temperature changes in the detection zone remote from the housing 15 110 as previously described. The second sensor 380 may be an infrared sensor or PIR sensor. The processor 300 may be further configured to process data from the second sensor 380 to detect changes in radiant energy associated with the presence and/or motion of at least a person, or potentially an animal or vehicle, depending on how the sensor settings and detection zone were configured, and also based on 20 access to normative data for classifying the objects 600.

[0116] Figure 18 illustrates an exemplary external device 700 for remotely configuring settings of the electronic lock system 100, according to some embodiments of the invention. The external device 700 may include a handheld or portable device. The external device 700 may be a mobile device, tablet or laptop 25 computer. The external device 700 includes a user interface 710 having a display screen 760 and is in communication with a processor 720. A memory device 730 is also in communication with the processor 720. The memory device 730 may store a computer program product including operating instructions, e.g., a software application, which are run by the processor 720. A user or operator is able to access 30 the software application via the user interface 710 and interact with the application. The external device 700 also includes an antenna 770 having a transmitter 740 and receiver 750, which may enable wireless communication with the microcontroller 240 of the electronic lock system 100. The wireless communication may be enabled via

31

Bluetooth, or alternatively, other wireless forms of communications as previously described. described.

[0117] Figures 19A-J illustrate a computer program product, that is a software application, embodied on a mobile device 700 for remotely configuring settings of the electronic lock system 100, according to some embodiments of the invention. As noted with reference to Figure 18, the memory device 730 may store a software application, which includes a number of instructions to be performed by the processor 720. The instructions may cause the processor 720 to wirelessly transmit, via the antenna 770, one or more parameters for defining a detection zone of the sensor module 300 of the electronic lock system 100. The instructions may also cause the processor 720 to wirelessly configure an operating mode of the electronic lock system 100. Three operating modes of the electronic lock system 100 may be configured, including a disabled mode, a standalone mode, and an integrated mode, as previously described.

[0118] Figures 19A-J illustrate a software application which is available on a mobile device 700 which includes a user interface 710 having a display screen 760. The display screen 760 may be a touch screen operable by a user. Figure 19A shows a first screen for selecting an electronic lock system 100, namely a maglock, in the software application. A user is able to select the maglock and connect with it via Bluetooth by tapping the connect button on the touchscreen. A user can also scan for other devices via Bluetooth if the desired device for connection is not already shown.

[0119] Figure 19B the illustrates that various information may be displaced for the device once selected, including the name, version, build, date and time of access. A login screen is also provided for an added layer of security.

[0120] Figure 19C shows a drop-down menu in the software application while on the screen shown in Figure 19B. A user can access a home screen, a login screen, the device, updates and information about the software application.

[0121] Figures 19D-J show various screens in the software application upon selection of the device of interest, which is in this case is the maglock previously mentioned, which corresponds to the electronic lock system 100. Figure 19D shows an information screen for the device. Figure 19E provides for configuration of settings

32

of the system 100. It is possible to select a desired indicator colour, which may be red or green, for example, of the LED lights of the electronic lock 200 and/or sensor module 300. The setting option may provide for the colour of the LEDs when locked. It is also possible to select a lock mode being a master or slave depending on the 5 desired configuration. Finally, the value for the Hall sensor offset may be selected.

[0122] In relation to selection of the master or slave lock mode, this option is provided as the electronic lock system 100 may be provided with a single or double electromagnet 111 in some configurations. The master electromagnet will be associated with the sensor module 300, and the other electromagnet will be the slave. 10 When a double magnet housing is used, the main PCB 230 with the sensor module 300 connected, will act as the master unit. When the sensor module 300 is triggered by the presence or motion of the object 600, an output from the main PCB 230 via the sensor module 300 wiring, can be connected to the speaker 254, for example, on the second (slave) electromagnet. This will allow both electromagnets to unlock 15 simultaneously on the sensor module 300 activation. The on-board Bluetooth module for the master electromagnet may also be used to send a signal to the slave electromagnet to release the lock 200.

[0123] Figure 19F shows a screen in the software application upon selection of the motion detector 300. It is possible to select the operating mode, which may 20 include a standalone mode as shown, or optionally also disabled and integrated modes, as viewed in Figure 19G. A user is able to adjust two parameters, which are used to define a detection zone of the sensor module 300, being the range and height as previously described. The range being the desired distance for detection of an object 600 from the door 520 or doorway 500, and the height being the length 25 dimension of the door 520 or door height. The user is able to select numbered options via a slide bar for each of the range and height. The options correspond to various desired ranges of actual measurements of the range and height. In Figure 19F, option 1 for the range and height is currently selected. Figure 19H shows that a user may interact with the touch screen to operate the slide bar and change the range and 30 height parameters. The range is now selected to option 6 while the height remains at option 1. The various options for the range and height are programmable in the software application.

[0124] Figure 191 shows another screen in the software application for monitoring the voltage at the main input and the hall sensor. The voltages may be displayed for the user to view. Figure 19J shows a final screen where the user is able to disconnect the mobile device 700 from the electronic lock system 100.

5 [0125] Embodiments of the invention provide a number of advantages over electronic door locks currently available in the market. For example, the electronic lock system 100 includes a sensor module 300 which provides for detection of the presence and/or motion of an object 600 in relation to the doorway 500. The sensor module 300 may advantageously include a microwave or radar sensor 310 to enable 10 detection of motion of an object 600, and optionally, direction of the motion towards the door 520 or doorway 500. The sensor module 300 thus enables reduction in false triggering of unlocking of the door 520 which may be caused by a person passing by the door 520 but not requiring access through the doorway 500. The electronic lock system 100 may also beneficially provide the senor module 300 integrated with the 15 electronic 15 electronic lock200. lock 200.

[0126] Embodiments of the lock system 100 may also advantageously enable wireless communication with the electronic lock 200 for setting parameters of the sensor detection zone from an external device 700. Additionally, a number of other settings may be configurable through wireless communication, such as an operating 20 mode of the lock system 100, single or double magnet use, indicator colours and the like. Advantageously, this means that once the lock system 100 is installed on the doorway 500, the installer or user no longer needs to climb up and down ladders in order to reach a manual push button 244 for re-programming the settings. Instead, the installer or user may use an external device 700, such as a mobile device, having 25 a software application for remotely configuring the settings of the lock system 100. This also enables more complex configuration of settings through the user selectable options on the software application in contrast to accessing a menu structure on the lock itself by a single push button. Thus, it is much simpler and easier for an installer or user to adjust the lock settings.
