Abstract

Field balancing may be performed with an irradiation system including a plurality of adjustable radiant-energy emitters. The irradiation system powers the radiant-energy emitters from a power source and radiant energy is emitted from the radiant-energy emitters, where an amount of radiant energy emitted from each emitter is capable of being varied based on power received from the power source. A plurality of radiant-energy sensors detects an amount of radiant energy which includes radiant energy created directly by at least one of the radiant-energy emitters. The amount of radiant energy detected at least two of the radiant energy sensors is compared, and at least one of the radiant-energy emitters is adjusted by varying the power received from the power source so that the amount of radiant energy detected at each of the radiant-energy sensors tends towards becoming approximately equal. The emitting of radiant energy from each radiant-energy emitter is terminated when a total amount of radiant energy emitted from the plurality of adjustable radiant-energy emitters exceeds a predetermined threshold value, where the threshold value is sufficient to allow the total amount of radiant energy emitted from the plurality of adjustable radiant-energy emitters to sanitize a particular area in which the emitters are located. 122-1 122-2 124-1 124-2 134-3 142-1 132-2 134-400 134-4 142-2 132-1 134-2

In particular embodiments, the radiant-energy sensors 134 am positioned above and forward of every other radiant-energy emitter 1.32* and protrude into the room 100 to achieve wide angle detection. In particular ep?ddip#^. season 134 may be angled to face down 1-3 degrees luorder to improve die eoilection of primary field radiant energy from the radiant-on ergy emitters ,132, flWTSj The. irradiation system. 130 may also include a hygrometer 140. The irradiation system 130 may further include control logic (not shown), a power component 136* a battery pack: 138, and two power cords (collectively 142), The control logic may; control the operation; pi the irradiation system 130 and may include both hardware and software. For example, the control logic may include a processor, memory, and circuitry that connects the processor to the memory and to of her components of the mediation system 130, The memory may include instruetions that, when executed by the processor,:: enables the irradiation system 13© to perform operations described herein. mm During operation, the power component 136 receives electrical power Horn one or more power sources ami uses the received electrical power to power the irradiation system 130, The amount of power available font a siogie power cireiui can limit the flux of radiant energy that can he emitted from, the eradiation system 130, Thus, the power comportent 136 is designed to be able to receive electrical powerlorn a: plurality of power sources. For example, the power cords 142 may he connected to two different power circuits (he,, two different power sources). The battery pack 13b may be an additional source of eleetriesl power to fbe power component 136. When the power component 136 receives electrical power from a plurality of power sources, the Irradiation system 1311 can emit more radiant energy in a particular amount of time than when the power; component 136 receives electrical power bom a single power source. When the power component 136 receives electrical power from a plurality of power sources, the irradiation system 130 can emit the same amount of radiant energy in a shorter amount Of time than when the power component 136 receives electrical power from a single power source. The single power sborce may be a single power cord 142 connected to a single power circuit. Also*, the single power source may be the battery pack 138, ffMB7J Each adjustable radiant-energy emitter 132 of the plurality of adiusiable radiant- energy emitters 132 emits &h adjustable Im of radiant energy during operation of the irradiation system: 130. Baeh redlant-euergy sensor 134 of the plurality of radlaotreuetgy sensors 134 detects radiant energy during;: the: opemtioti of the irradiation system 130. The radiant energy detected at each radiant-energy sensor 1:34 is the: field created by the radiantreuergy emitters. 132 and. primarily includes an. amount of radiant etlergy directly from, at least one adjustable radiant-energy emitter 132 of the plurality of ad|ustable radiant-energy emitters 132. ISach radiant-energy sensor 134 may also receive radiant energy from other radiant-energy emitters 132 and radiant energy from, other sources. For example, each radlanf-pergy sensor 1|4 may receive radiant; energy that has been reflected, off of the walls '1:02, 164,, 106, 108, iiimiture: 122, 124: In the room 100,: or off of any device itself, for example. In this embodiment, however,, there is bo meehauism to: measure the radiant energy ft»*», a. prteary mhad^ehergy emitter a ^dtantrenergy remitter, any reSeeted radiant energy, or the source of the reflected radiant energy. T he radiant-energy sensors 134 detect the strength of the ^jrecipdblpt: energy .field .cheated.ptimarily"by. the radiant-energy emitters 132 directly so that the irradiation system 130 may adjust the radiant-energy emitters 132 to balance the· field throngh the use of control logic, The control logic may adjust each of the plurality ofadjustable radiant-energy emitters 132 during operation of--.the irradiation system 130 mill the amount bfiadlafti :^erg^dfete«ted::at-<^0h ·ϊ^&®ί^Η0Γ§^όη$<ατis approximately equal. The control logic may adjust an adjustable mdisht-energy emitter 132 by 1) adjusting the adjustable Tims of radiant energy emitted from the acynstabie radiantrofiergy emitter 132, -2) adjusting the position of the adjustable radiant-energy emitter 132, or 3) by adjusting a reflector at the adjustable radiant-energy emitter i 32. f0O38j The adjustment of each adjustable flux may emulate the movement of an adjustable radiant-energy emitter 132 closer to an area of the room 100 or emulate the movement of an adjustable radiant-energy emitter .132 further from an area of the room 100. For example, a first adjustable radiant-energy emitter 132-1 may be emitting more radiant energy than is needed because of .the proximity of the left wall 102 and the front wall 108 to the adjustable radiant-energy emitter 132-1, A second adjustable radiant-energy emitter 132-2 may not be emitting a sufficient amount of fadiaut energy because of the distance of the rear wall 104 and the right wall 106 born fhe radiant-energy emitter 132-2, That is, the radiant energy emitted from the 'first adjustable radiant-energy emitter 132-1 is being applied: to a smaller area, than the area to which the radiant energy emitted from the second adjustable radianhenergy emitter 132-2; is being applied. Additionally, there are objects (e.g,> first bed 123-1:, second bed 122-2^ and. second, chair 1.24-2): in the general area to which the radiant energy emitted bpnvfhe seeoud adjustable radiant-energy emitter 132-2: is:being: applied, hi particular embodiments, the amount of radiant energy detected at first radiaahenergy sensor 134-1 and second mdiant-energy sensor I;34«2 will be greater thatf the amount of radiant energy detected at the third radiant-energy sensor: 134-3: and the fourth radiant-energy sensor 134-4, The controUogk. may decrease the flnx of radiant energy emitted from the first adjustable radiam-energy emitter 132-1, ertmiaiing a tiroyemeht of the first radianUeftergy emitter 132-1 away from that area. Similarly, the control logic may increase the flux of radiant energy emitted from the second adjustable mdiant'" energy emitter 132-2, emulating movement of the second adjustable radiant-energy emitter 132-2 toward that area.

The irradiation system 130 may continue adjusting the adjirstahie flux of radiant energy emitted: from each adjustable radiauf-enerpy emilter 132 until the energy detected at each radiant-energy sensor 134 hr approximately equal, Th e adjusting of the adjustable fluxes may be referred to as field balancing,,; Similarly, the Irradiatlou system 130 may continue to: adjust the position of each radiant-energy enfitte.r 132 or continue to adjust a reflector at each radiant-energy emitter 132 until the. amount 4f radiant energy detected, at each radiant-energy sensor 134 Is: approximately equal it should be noted that, with, the adjustment of radiant-energy emitters 132, more power may he used by a parti cute radiant-energy emitter 132 that is adjusted to emit radiant energy at a higher level or due to the: radlaM-energy emitter 132 being worn or not as effeetiye: as another radlantsenergy emitter 132, for example. Adiustmg the radiant-energy emitters 132 provides: the ah i lity :to use the power avail able to reduce treatment times. In. one embodiment,; the power consumption as monitored and adjusting of the radiant-energy emitters 1:3.2 stay he discontinued once the specified : available power is reached. Irrespective of whether only a single power source is available or multiple power sources are available is described above, this adjustment of the radiant-eoergy emitters 132 acts to limit the tmatment time for a pafocular target area, fiMOi In particular embodiments, 1.30 emits radiant energy ftOin each of the adjustable radiant-energy emitters 1:32 until a. total amount of radiant energy emittedfrom the adj ustable fadiant-energy emitters 132 reaches or exceeds a threshold value.
