  • Publication number: 20210244575
    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: 20210241894
    Abstract: Systems and methods of associating beds and/or rooms and/or patients are provided. One system and method involves using a signature of emitted light to determine a location of a patient bed in a healthcare facility. Another system and method involves reading a bar code from an array of redundant bar codes. Still another system and method involves manually entering location information on a graphical user interface of a patient bed for subsequent transmission. A further system and method involves sending bed ID and location ID along parallel paths from two independent circuits on a patient bed for receipt by two different transceivers and ultimately by two different remote computers that cooperate to associate the bed ID with the location ID. Still a further system and method involves using circuitry on a bed to mutate a received location ID and a bed ID into a single unique mutated ID such as by adding the location ID and bed ID and then performing a hashing operation.

  • Publication number: 20210128382
    Abstract: A patient support apparatus, such as a hospital bed, includes an alert light assembly or an alert light module having separate zones that are individually illuminated to convey information regarding respective alert conditions. The zones each have indicia related to a particular condition of the patient support apparatus. The illuminated zones are each sufficiently large so as to be seen from afar, such as on the order of ten feet or more. Alternatively or additionally, a GUI of the patient support apparatus displays alert indicia as part of a screen saver. Further alternatively or additionally, the patient support apparatus illuminates an alert light in a manner indicating an optimal time for taking a patient's vital signs.

  • Patent number: 10973720
    Abstract: A method of determining information about a device includes the steps of 1) acquiring an image of at least a portion of the device, 2) comparing the information content of the image to the information content of at least one record of a library, and, 3) if the comparison is positive, reporting that the device is in the possible state represented by the library record. A method which depends on calculations based on the acquired image rather than on comparison of the information content of the image to the information content of one or more library records is also disclosed. A system for determining the state of the device is also disclosed.

  • Patent number: 10959659
    Abstract: A system for detecting an incontinence event includes a pad which is deployable on a mattress and which, as deployed, has a first conductor and a second conductor and in which the first conductor and the second conductor are not in electrical communication with each other. The system also incudes an RFID reader subsystem having a processor and an array of two or more spatially distributed antennas. The system is adapted to A) command transmission of energy from the antenna array at a variety of powers and at various frequencies, B) monitor the antenna array for a return signal resulting from the spatially and temporally varying transmission, and C) communicate a WET or DRY status to a destination. The WET or DRY status depends on a moisture status indicator of the return signal.

  • Publication number: 20200261279
    Abstract: An incontinence detection pad has an RFID tag in which an authentication code, such as an electronic product code (EPC), is stored. A reader in wireless communication with the RFID tag of the incontinence detection pad verifies that the incontinence detection pad is an authorized detection pad. Thus, unauthorized incontinence detection pads that do not have the proper authentication code are not able to be used in an incontinence detection system.

  • Publication number: 20200075173
    Abstract: A method of responding to the presence of a communicable condition includes the steps of 1) acquiring a spatial/temporal trajectory of each member of a population of interest, 2) acquiring a spatial/temporal trajectory of zero or more objects of interest, 3) identifying a communicable condition associated with at least a first member of the population, 4) and, subsequent to the identifying step, assessing possible transfer of the communicable condition to one or more other members of the population. The assessment is based, at least in part, on the acquired spatial/temporal trajectories. A related apparatus includes a processor and machine readable instructions. The instructions, when executed by the processor, carry out the above enumerated steps 1, 2, 3 and 4.
