  • Patent number: 10881328
    Abstract: Systems and methods for determining and tracking a positioning of a subject and displaying an image of a model of a subject are disclosed. A system includes a plurality of thermal markers, one or more thermal imaging devices arranged to capture baseline and updated infrared images of the surface and the thermal markers, and a computing device communicatively coupled to the thermal imaging devices. A first thermal marker is arranged at a first location relative to the surface. The computing device receives the baseline and updated infrared images and determines a corrective movement for at least one of the subject and the surface to align the thermal markers in the updated infrared image with the thermal markers in the baseline infrared image based on a location of the thermal markers in the baseline infrared image and a location of the thermal markers in the updated infrared image.

  • Patent number: 10856775
    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.

  • Publication number: 20200289338
    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.
