  • Publication number: 20190167500
    Abstract: A patient support system for supporting a patient includes a core support structure which includes supportive foam. The support structure has an upper surface and a lower surface. A radar apparatus, including at least one antenna situated beneath the upper surface and spatially separated therefrom, is adapted to emit a pulse which travels through the support structure and is reflected, by either the upper surface or a surrogate thereof, as a reflected signal back to the radar antenna. The emitted pulse and reflected signal comprise a ranging signal. The patient support system also includes circuitry that determines a life parameter of the core support structure as a function of at least the ranging signal. The patient support system also includes an RFID tag having a memory. The RFID tag is in communication with the circuitry.

  • Publication number: 20190130068
    Abstract: A patient care environment includes a monitoring device and a vital sign device, where the vital sign device communicates patient vital sign data to the monitoring device. A site key, entity keys, and key combining algorithms are used to secure communications in the patient care environment. Neither the site key nor the entity keys are communicated between the monitoring device and the vital sign device. The monitoring device may use the site key and entity keys to decrypt encrypted messages that have been previously stored in the vital sign device and transmitted back to any monitoring device containing the correct set of site and entity keys. The site key and entity key may also be used during the discovery and/or connection operations between the monitoring device and the vital sign device to associate a wirelessly connected vital sign device with a patient record.

  • Publication number: 20190053707
    Abstract: A subject monitoring system operates to detect a current status of a subject in a subject arrangement area, such as on a bed, and predict an upcoming status of the subject. The system includes a subject status detection device that may use a radar signal. A radar signal is transmitted toward the subject and is used to detect a subject status, such as a subject position, a subject incontinence condition, and a physiological condition of the subject. One example of the radar signal includes a millimeter wave.

  • Publication number: 20190015277
    Abstract: A patient immersion sensor includes a radio detection and ranging (RADAR) apparatus to determine a time of flight (TOF) of a RADAR pulse and a reflected signal that is reflected by a patient or by a portion of a patient support surface supporting the patient. The TOF is indicative of an immersion depth or a distance toward bottoming out of a patient supported on the patient support surface, such as a mattress or a pad. The RADAR apparatus emits pulses of very short duration so as to be able to detect objects, such as a patient or a portion of a mattress or pad, at very close distances. The RADAR apparatus may use time-of-flight (TOF) between transmission of the pulse and receipt of a reflected signal to determine a distance toward bottoming out by the patient, thereby to determine if the patient is properly immersed into the patient support surface.

  • Publication number: 20190015048
    Abstract: A system for detecting one or more physical assessment parameters of a subject includes a sensing patch and a processor. The sensing patch is configured to sense signals from the subject corresponding to one or more physical assessment parameters, reduce sensed parameter data corresponding to the sensed signals, and transmit the sensed parameter data. The sensing patch also includes at least one adjustable sensing patch parameter. The processor is separate from the sensing patch and configured to receive the sensed parameter data from the sensing patch and transmit a command to the sensing patch. The sensing patch is configured to perform different amounts of data reduction on the sensed parameter data before transmitting the sensed parameter data to the processor. These different amounts of data reduction are determined at least in part by one or more system parameters.

  • Patent number: 10085641
    Abstract: A method for obtaining physiological data from a medical sensor device includes detecting a proximity of the medical sensor device by an electronic computing device. After the proximity is detected, a message is received from the medical sensor device. A determination is made as to whether the received message includes configuration information for a wireless communication link. When the received message includes the configuration information for the wireless communication link, the wireless communication link is used to receive physiological data from the medical sensor device and the received physiological data is processed at the electronic computing device. When the received message does not include configuration information for the wireless communication link, a determination is made as to whether the received message includes physiological data. When the received message includes the physiological data, the physiological data is processed at the electronic computing device.

  • Patent number: 9973883
    Abstract: A method for automatically adding a first sensor device to a first personal area network in a healthcare application includes receiving a signal with out-of-band pairing data at the first sensor device. The first sensor device is disposed on a patient's body. The out-of-band pairing data is injected into the patient's body by a second sensor device disposed on the patient's body. Pairing data is extracted from the received signal at the first sensor device. Using the pairing data, the first sensor device is added to the first personal area.

  • Patent number: 9959315
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for context scoring adjustments for candidate answer passages. In one aspect, a method includes scoring candidate answer passages. For each candidate answer passage, the system determines a heading vector that describes a path in the heading hierarchy from the root heading to the respective heading to which the candidate answer passage is subordinate; determines a context score based, at least in part, on the heading vector; and adjusts answer score of the candidate answer passage at least in part by the context score to form an adjusted answer score. The system then selects an answer passage from the candidate answer passages based on the adjusted answer scores.
