Abstract: Embodiments relate to a device for mounting on a wall for monitoring an environment. In one embodiment the device comprises: a body comprising: an active reflected wave detector; and a processor coupled to the active reflected wave detector, the processor configured to: control the active reflected wave detector to measure wave reflections from the environment to accrue measured wave reflection data, and identify a status of a person in the environment based on the measured wave reflection data, wherein the processor assumes, for said identification, that the active reflected wave detector is at an operating height above a floor of the environment. The device comprises a cord extending from the body, the cord having a length for ending at the floor when the device is mounted with the active reflected wave detector at said operating height and the cord is freely hanging and straight.

Abstract: A method comprising: controlling an active reflected wave detector to measure wave reflections from an environment using a first frame rate to accrue measured wave reflection data for a classifier, after a first amount of time, determining whether a predefined criteria is satisfied, wherein satisfaction of the predefined criteria is indicative of the classifier being likely to successfully identify a fall status of a person in the environment by a second amount of time of accruing measured wave reflection data from the active reflected wave detector, the second amount of time being greater than the first amount of time; in the event that the predefined criteria is not met, the method comprising controlling the active reflected wave detector to accrue measured wave reflection data at a lower second frame rate for classifying the fall status based on measured wave reflection data accrued at the lower second rate.

Abstract: A location of a person is identified. A controller core is configured for interfacing with a plurality of sensing devices at a plurality of locations. Each sensing device has a sensor for detecting a threat-condition and an acoustic sensor for generating an acoustic indicator indicative of an incident acoustic wave. The controller core is configured to: (i) upon receiving a trigger, instruct wireless transmission to the sensing devices, of a request for an acoustic indicator generated in the sensing device, wherein the request configures each of the sensing devices to activate a process in respect of an incident acoustic wave; (ii) receive one or more of said requested acoustic indicators; and (iii) based on the received one or more acoustic indicators, identify a location of the person (103) within the building.

Abstract: A system for estimating breathing frequency and heartbeat frequency of a subject, comprises at least one ultra-wideband (UWB) transceiver, connected to at least one hardware processor, configured to: receive a plurality of readings from the UWB transceiver, each of the readings having a time and comprising a plurality of intensity values at the time, each of the intensity values having a corresponding distance value representing a distance between the UWB transceiver and the subject; determine a Range-Doppler map from the plurality of readings; analyze the Range-Doppler map to determine a breathing frequency value of the subject; perform null steering of a plurality of Doppler-map frequencies in the Range-Doppler map to nullify the breathing frequency value and integer multiples of the breathing frequency value to obtain a plurality of combined frequencies; and determine a heartbeat frequency value for which a plurality of computed frequencies corresponds with the plurality of combined frequencies.

Abstract: In this disclosure, a person may be identified by: (i) receiving a first message comprising an ID of a first device and a hardware ID of a personal emergency device; (ii) linking the personal emergency device with personal data of the person, the personal data being associated with the ID of the first device; and (ii) receiving a second message from a mobile device comprising the hardware ID of the personal emergency device. In response to receiving the second message, and/or receiving a subsequent message received via the mobile device and comprising the hardware ID of the personal emergency device, a message is transmitted to a monitoring station based on the prior association of the personal data with the hardware ID of the personal emergency device. The message includes the personal data or an identifier for identifying said personal data.

Abstract: A hub device is disclosed comprising a first antenna communicating with a peripheral device, a second antenna communicating with a remote station. In a first operation mode, transmission by the first antenna is at a first bit rate. Operation may be triggered to switch to a second mode in which a stream of data is received from the remote station, and there is a transmission to the first peripheral device, of data derived from the data stream, the transmission being from the first antenna while the stream of data is being received on the second antenna. In the second mode, the transmission from the first antenna is at a second bit rate that is faster than the first bit rate such that transmitting the derived data at the second bit rate uses a shorter duty cycle than required to transmit the derived data at the first bit rate.
