Abstract: Techniques are disclosed for detecting a presence of a biological substance through an article such as a diaper. For example, a detection system causes a light source to transmit light through the article. The light includes a peak wavelength that corresponds to an excitation wavelength of a biological substance that may be present in the article. The detection system detects a measurement of light intensity within a range of emission wavelengths of the biological substance. By comparing the measurement of light intensity to a threshold, the detection system identifies a presence of the biological substance on the article.

Abstract: Systems and methods for detecting determining a volume of urine in an absorbent article such as a diaper. A diaper loading application obtains a first measurement of ambient light received from a photodetector while a light source is off and a second measurement from the photodetector while the light source is transmitting light on an absorbent article. The application determines a normalized measurement of light reflected from an absorbent article by removing an ambient light signal from the second measurement based on the first measurement. The application determines, from the normalized measurement, a presence of urine in the absorbent article. The application further determines an estimated volume of urine in the absorbent article, wherein the determining is based on an elapsed time since the presence of urine and an activity state of an infant wearing the absorbent article.

Abstract: One disclosed example method includes receiving sensor data from a biosensor; determining an event using a first analysis based on the sensor data, the first analysis having a first power cost; determining to perform a second analysis based on the event; in response to determining to perform the second analysis, performing the second analysis based on the sensor data, the second analysis having a second power cost greater than the first power cost; and wirelessly transmitting results of the second analysis to a remote device.

Abstract: Techniques for detecting a color of a color changing indicator in the presence of ambient light. In an example, 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.
