  • Publication number: 20190060137
    Abstract: An absorbent article has one or more fluid filter layers to inhibit electrode traces from being exposed to low volumes of fluid to reduce the number of false positives that are indicated by an RFID tag of the incontinence detection pad. An antenna inlay has a sacrificial trace portion to permit testing for proper operation of an RFID chip electrically coupled to the antenna inlay. After testing, the sacrificial trace portion is severed. A fluid barrier layer blocks fluid from reaching portions of electrode traces that are located on a backsheet outside a periphery of an absorbent core of an incontinence detection pad. The power at which an antenna transmits to wirelessly energize a passive RFID tag of an incontinence detection pad is controlled to reduce the number of false positives indicated by the RFID tag.

  • Publication number: 20180116879
    Abstract: A disposable incontinence detection system monitors an area for incontinence events. The incontinence detection system includes a substrate having a length and a width defining a monitoring area. Additionally, the incontinence detection system includes a moisture sensor positioned within the monitoring area. The moisture sensor includes a circuit that includes traces spaced apart from each other such that the presence of moisture bridging a space between at least two of the traces will close the circuit. Additionally, the circuit includes a removable conductor coupled to one of the traces such that removal of the conductor irreversibly prevents the trace from closing the circuit. The moisture sensor is configured to determine whether the circuit has been closed.

  • Publication number: 20170156638
    Abstract: A method of evaluating the likelihood that an occupant will exit an occupant support comprises determining if the location of the occupant on the occupant support is displaced relative to a reference location, and if the location of the occupant is so displaced, designating that the occupant is at a risk of exiting the occupant support which is elevated relative to the baseline risk. A support apparatus comprises a framework, a mattress, sensors distributed on the support apparatus to sense occupant weight distribution on the support apparatus, and a processor adapted to designate a risk of occupant egress as a function of the direction of the occupant weight distribution and the elevation status of the perimeter panels.
