  • Publication number: 20230389826
    Abstract: Systems and methods for monitoring a positioning and vital signs of a subject are disclosed. A method includes receiving, by a processing device of a monitoring device, LWIR image data from a first imaging component of the monitoring device and NIR image data from a second imaging component of the monitoring device, determining one or more boundaries of the patient support apparatus from the NIR image data, constructing one or more virtual boundaries that correspond to the boundaries of the patient support apparatus, determining a location of the subject with respect to the virtual boundaries from at least one of the LWIR image data and the NIR image data, determining a facial temperature and a heart rate of the subject from the LWIR image data, and determining a respiration rate of the subject from at least one of the LWIR image data and the NIR image data.

  • Patent number: 11707388
    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: 20210045677
    Abstract: A system for addressing sleep disordered breathing in a person, comprises an acoustic sensor, a processor, and a support apparatus for supporting the person. The support apparatus includes or is receptive to receiving a turn effector. The system also includes processor executable instructions which, when executed by the processor, cause the system to 1) determine upper airway orientation of the person based on information from the acoustic sensor, 2) determine, based on the information from the acoustic sensor, if the person is experiencing sleep disordered breathing, and 3) if the person is experiencing sleep disordered breathing, command operation of the turn effector to act on a component of the support apparatus thereby changing the orientation of the upper airway of the person from an initial orientation to a target orientation. The target orientation is an orientation more conducive to relieving the sleep disordered breathing than is the initial orientation.
