  • Patent number: 9119748
    Abstract: An electronic discriminating device incorporating a non-contact electronic sensor array, a controller, and a signaling device that may indicate the presence of urine and/or bowel movement is disclosed. In particular, the electronic discriminating device can discriminate between an insult of urine only and an insult containing bowel movement. The device can then generate different alerts based on the type of insult. The electronic discriminating device may also emit a signal at or near the opening of an absorbent article or transmit the alert wirelessly to a radio, computer device, or smartphone.
