Abstract

flow meter, comprising: a coupler adapted to couple to a drip chamber; a support member operatively coupled to the coupler; a modulatable backlight assembly configured to provide a first backlight and a second backlight; an image sensor having a field of view and operatively coupled to the support member, wherein the image sensor is configured to view the drip chamber within the field of view and the modulatable backlight assembly; and at least one processor operatively coupled to the image sensor and the modulatable backlight assembly, wherein: the at least one processor receives data from the image sensor having at least a portion of the modulatable backlight assembly represented therein, and the at least one processor is configured to modulate the backlight assembly to the first backlight when estimating a drop size and to modulate the backlight assembly to the second backlight.

Claims (3)

What is claimed is:
1. A flow meter, sing: a coupler adapted to couple to a drip chamber; a support member operatively coupled to the coupler; a modulatable backlight ly configured to provide a first backlight and a second backlight; an image sensor having a field of view and operatively coupled to the support member, wherein the image sensor is configured to view the drip r within the field of view and the modulatable backlight ly; and at least one processor operatively coupled to the image sensor and the modulatable backlight assembly, wherein: the at least one processor receives data from the image sensor having at least a portion of the modulatable backlight assembly represented therein, the at least one processor is configured to modulate the backlight assembly to the first backlight when estimating a drop size and to modulate the backlight assembly to the second backlight.
2. The flow meter according to claim 1, wherein the first backlight is a diffuser backlight having no pattern and the second backlight is a diffuser backlight having a striped n.
3. A flow meter according to claim 1, substantially as herein bed or ified. DEKA PRODUCTS LIMITED PARTNERSHIP By their Attorneys HENRY HUGHES IP
