Abstract: A method for synchronizing recordings of two wearable devices (12,14) worn by a user (16) in a specific use case is designed to measure a characteristic behaviour of the user over a period of time. The method comprises acquiring first recordings via a first wearable device (12) operable via a first clock, and acquiring concurrent second recordings via a second wearable device (14) operable via a second clock, wherein each clock has a clock drift and offset. The first and second wearable devices are synced with a hub executable app (18) executed on a hub device (20). A clock-time correction (62) is implemented via the hub executable app before processing (64) the respective recordings for the specific use case. The clock-time correction ensures that respective recordings have been corrected in time so that a difference between clocks, or clock drift, of the two wearable devices is no more than a threshold duration of a shortest event specific to the characteristic behaviour being measured.

Abstract: A first responder network is a network that is used by first responders for communicating between devices typically used by first responding officers. An MCI describes an incident in which emergency medical services are overwhelmed by the number and severity of casualties. A wireless communication system for first responder networks is proposed that can securely register (onboard) a variety of wireless devices to ensure a quicker response time in the MCI area. Existing wireless devices belonging to both triage officers and casualties in the MCI area can automatically be registered to a first responder network to enhance coverage in the MCI area. Expansion of a wireless infrastructure of the first responder network can be enabled by securely registering alien central nodes (e.g., base stations) on an on-demand basis.

Abstract: A sleep monitoring system has a movement sensing arrangement and a controller for identifying from the movement sensing arrangement output signals sleep-disordered breathing events. Seismocardiography signals are recorded and analyzed to determine repetitive patterns, from which an inter-beat interval time series is derived without identifying specific elements of the repetitive patterns. The sleep-disordered breath events are derived from the inter-beat interval time series. In this way, SCG signals can be used for sleep monitoring in a robust and reliable way.

Abstract: A concept for monitoring a subject employs: a first sensor output signal representative of detected air pressure; and a second sensor output signal representative of a detected property of at least one of: the subject; and the environment. A dressing activity of the subject is determined based on the first sensor output signal and the second sensor output signal. Information about a dressing activity of the subject may, for example, be useful for the purpose of assessing the subject's physical and/or mental abilities.

The PPG includes an optical detector (22) and at least one light source (20a, 20b). Disposed between the at least one light source and the optical detector is a light-intercepting surface element (28), adapted to be absorptive of light of at least a majority of a spectral composition which is generated by the at least one PPG light source (20a, 20b).

Abstract: A pressure distribution profile of a subject lying on a mat is used to derive a measure of pulse wave velocity. Beat locations are identified where beat pressure signals are identified, and pulse timing information is obtained from the beat locations. By determining a subject posture, the beat locations are mapped to anatomical body locations and arterial path length information is obtained for the anatomical body locations. A pulse wave velocity is then estimated from the pulse timing information and arterial path lengths. This method enables measuring the pulse wave velocity during sleep in a comfortable, easy and unconstrained manner. This is accomplished by analyzing signals from a pressure sensitive surface for example on top of a bed mattress or by embedding a pressure sensitive layer in the mattress.

Abstract: A wearable device may take a set of health inputs from embedded body sensors for the duration of an activity performed by a user of the wearable device. Based on these inputs, the wearable device can calculate a health parameter (e.g., calories burned during the activity). The wearable device can also track its location during the activity, and provide this location to a geolocation data network. The geolocation data network may provide geolocation data (e.g., weather/environmental/terrain data) pertaining to the wearable device's location. The wearable device can then modify its measurements and/or calculated health parameters based on the geolocation data (e.g. Increasing calories burned during a run due to high heat and uphill terrain in the location of the run).

A monitoring system monitors detection by at least one of the first and second detectors an optical calibration signals, for performing time calibration between the first and second PPG sensors. This system makes use of two PPG sensors. To enable these sensors to be independent units, rather than being fully integrated into a combined system, a calibration system is provided. Based on detected optical signals, the behavior over time of each PPG sensor can be monitored and thus calibration can take place.

Abstract: A sensor system is for determining a breathing type of a subject. It has first and second electromagnetic radiation (e.g. optical) sensors, for example PPG sensors. The sensors are for application to the skin of the subject at different sensor locations. The signals from the first and second sensors are analyzed to determine if there is predominantly a first breathing type (e.g. chest breathing) or predominantly a second breathing type (e.g. belly breathing), or a mixture of the first and second breathing types.
