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: An optical vital signs sensor (100) is provided, which comprises a PPG sensor (102), a force transducer (130) configured to measure a force applied via the PPG sensor (102) to a skin (1000) of the user and a processing unit (140) configured to extract information regarding a blood volume pulse from the output of the PPG sensor (102) and to map the extracted information to the blood pressure value at a specific force applied to the PPG sensor (102).

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.

Abstract: A system 1, a corresponding method and computer program for assisting exercising of a subject 7 is provided. The system comprises: an exercise state providing unit 10 for providing an exercise state of the subject 7 for or during an exercise session, a fatigue level determination unit 20 for determining a fatigue level of the subject 7 based on the exercise state of the subject 7, a fatigue level threshold determination unit 30 for determining a fatigue level threshold for the subject 7 for the exercise session, and an evaluation unit 40 for evaluating the fatigue level in comparison to the fatigue level threshold. It provides a more versatile system 1 for assisting exercising of a subject 7 and further provides an improved exercising assistance for the subject 7.

Abstract: The present invention relates to a breast shield arrangement (1) for a breast pump (2) comprising: a breast shield (3) for receiving a user's breast therein, and a sensor (4) for transmitting an input signal into the breast and receiving a corresponding reception signal in response, said reception signal indicating changes in milk flow in the breast.

Abstract: A sensor system comprises first and second PPG sensors. 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 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).
