An electronic patient monitoring system and method of operation that includes one or more generally non-metal, tamper-resistant patient identification and monitoring devices, an observer transmitter/receiver device configured to receive and detect one or more beacon signals that exceed a predetermined threshold from at least one of the not easily removable patient identification and monitoring devices, set a time to hold open a window for a response on the transmitter/receiver device, and send a request for information to the observer with the transmitter/receiver device, and a central computer system. Each of the transmitter/receiver device and the central computer system, including, at least, a computer processor, communications components and system software to communicate with the observer transmitter/receiver device at specified/predetermined time intervals to receive observer- and patient-specific information.

The invention relates to a system (100) and a method (500) for controlling a cardiac support system (10), comprising a first extracorporeal control device (110), wherein the first control device (110) is or can be connected to the cardiac support system (10) with a wire or a first coil (150) for communication and/or energy transfer, and comprising a second extracorporeal control device (120) which is wirelessly connected to the first control device (110). The invention also relates to a cardiac support system (10) having a control system according to the invention (100).

A first electronic device may determine that a distance between the first electronic device and second electronic device has exceeded a threshold distance. The first electronic device may determine whether movement of the first electronic device or movement of the second electronic device caused the distance to exceed the distance threshold. Based upon the determination of whether movement of the first electronic device or movement of the second electronic device caused the threshold to be exceeded, the first electronic device may generate one or more alert notifications to notify the user that the distance has exceeded the threshold.

A wireless animal location system is provided that identifies a location of a pet roaming within an environment using a single base unit. The wireless animal location system tracks and manages animal behavior in the environment using information of pet location.

An electronic patient monitoring system and method of operation that includes one or more generally non-metal, tamper-resistant patient identification and monitoring devices, an observer transmitter/receiver device configured to receive and detect one or more beacon signals that exceed a predetermined threshold from at least one of the not easily removable patient identification and monitoring devices, set a time to hold open a window for a response on the transmitter/receiver device, and send a request for information to the observer with the transmitter/receiver device, and a central computer system. Each of the transmitter/receiver device and the central computer system, including, at least, a computer processor, communications components and system software to communicate with the observer transmitter/receiver device at specified/predetermined time intervals to receive observer- and patient-specific information.

Active radio-frequency identification, RFID, tag, and a product surveillance method using active RFID tags. The method includes: transmitting (202), by an active RFID tag, continuously a signal comprising an own identifier according to a predetermined schedule; receiving (204), by the active RFID tag, continuously a plurality of signals comprising a plurality of foreign identifiers transmitted by a plurality of other active RFID tags according to the predetermined schedule; measuring (206), by the active RFID tag, a received signal strength indication, RSSI, of each received signal; storing (208), by the active RFID tag, each foreign identifier of a signal whose RSSI exceeds a predetermined strength threshold; detecting (210), by the active RFID tag, that a signal with a stored foreign identifier is no more received according to the predetermined schedule and marking (212), by the active RFID tag, said stored foreign identifier.

Devices and methods for locating accessories of an electronic device are provided. In one example, a method may include detecting parameters associated with disconnecting an accessory from the electronic device. The electronic device, or an associated device, may store the detected parameters so that the detected parameters are accessible if the accessory becomes lost. The electronic device may receive a request from a user of the electronic device for assistance in locating the accessory. In response to the request for assistance in locating the accessory, the electronic device may provide the stored parameters to the user of the electronic device to aid them in searching for their lost accessory.

A position tracking system for Tags to collect relative proximity to other Tags using received signal strength, with methods to reduce power consumption with controlled degradation in overall system performance such as location accuracy and frequency of location updates. Configurable parameters for control of tag functions facilitate performance tradeoffs against application requirements. System architecture using mobile phone and gateway for uploading data enables efficient upload of tag data without user intervention. Applications of the disclosure include self-quarantine, contact tracing, mother-infant pairing, location history tracking, and personnel-asset usage monitoring.

A wireless device includes a user interface that generates a pairing signal in response to an indication from a user to pair the wireless device to at least one remote device and generates a first location request signal in response to a second indication from a user to locate the at least one remote device. A short-range wireless transceiver communicates RF signals to pair the wireless device to the at least one remote device and that transmits a first RF paging signal to the at least one remote device in response to the location request signal.

A method for determining cause of a disconnection between a computing device of a motion tracking system and one or more sensors of the system, the sensors arranged on a person's body, the computing device configured to at least receive data through a wireless communications connection. Each sensor is configured to at least transmit data through the connection. The method includes measuring a signal strength of the connection with each sensor while the communications are established; processing signal strength values corresponding to a sensor when it has been disconnected from the computing device to determine if the sensor has been disconnected due to a distance increase between the person and computing device; and providing or commanding the provision of at least one user perceptible signal when the computing device has determined that at least one sensor has been disconnected due to a distance increase between the person and computing device.
