Abstract:
Systems and methods for detecting a color of a color changing indicator in the presence of ambient light. A system includes a light source, a photodetector, and a processor. The processor obtains a first measurement of ambient light received from the photodetector while the light source is off. The processor causes the light source to transmit light. The processor obtains a second measurement from the photodetector during the transmission, the second measurement including the ambient light and the pulsed light reflected from an object. The processor determines a color of the color changing indicator by removing an ambient light signal from the second measurement based on the first measurement and therefrom determines a volume of bodily exudate present.

Claim (Index 13):
A sensor package comprising:\n a thin flexible substrate adaptable for placement in or on an absorbent article configured for receiving bodily exudate; a light source configurable to provide transmitted light to a surface or a layer of the absorbent article; a photodetector configurable to obtain a first measurement of returned light when the light source is off and a second measurement of returned light when the light source is on; and a processor configured to:\n obtain a first measurement of ambient light received from the photodetector while the light source is off; \n cause the light source to transmit light; \n obtain a second measurement from the photodetector during the transmitted light, the second measurement comprising the ambient light received from the photodetector and the light reflected from an object in the absorbent article; \n determine a color of the object by removing an ambient light signal from the second measurement based on the first measurement; and \n a microcontroller configured to:\n receive, from the processor, the color of the object; \n retrieve from a memory, a set of coefficients that map the color of the object to a volume of bodily exudate \n determine, from the set of coefficients and a stored color calibration value, a presence of bodily exudate in the absorbent article; wherein the light source, photodetector, and processor are disposed on the thin flexible substrate.
