    Sensor for Urine and Stool Detection:

    U.S. Patent No. 9,820,891

    01.05.18
    Eyall Abir, Petach Tikva, Israel
    Assigned to Digisense Ltd, Petach Tikva, Israel; and Expro3, LLC, Coral Gables, FL.

    Filed: 7/31/14
    Issued: 11/21/17

    A sensor, wherein the sensor is configured to detect both urine and stool, the sensor comprising: a housing configured to attach to a plurality of garment layers, containing a) at least one light source configured to illuminate the plurality of garment layers with visible light, whereby the visible light reflects off the plurality of garment layers; b) at least one visible wavelength photodetector configured to receive the reflected visible light and output an indication of an amount of the reflected visible light over time, wherein the amount of the reflected visible light is altered by the presence of either urine, stool, or both urine and stool; and c) an electronic circuit configured to analyze the output of the at least one visible wavelength photodetector and detect a presence of urine or stool in the plurality of garment layers, the detecting being based on a change in the output of the at least one visible wavelength photodetector exceeding a first threshold value, the first threshold value representing a magnitude of the change in the output of the at least one visible wavelength photodetector, the electronic circuit further configured to distinguish between urine and stool by evaluating a slope of the output of the at least one visible wavelength photodetector with respect to time, the electronic circuit identifying urine if the slope exceeds a second threshold value and identifying stool if the slope does not exceed the second threshold value, the second threshold value representing a rate of the change in the output of the at least one visible wavelength photodetector.
