Abstract: There is provided a device and a method of operating the device for determining whether the device is immersed in a fluid. An acceleration signal for the device is acquired (302) and a pressure within the device is detected (304). It is determined whether the device is immersed in a fluid based on a comparison of the acquired acceleration signal with the detected pressure (306).

Abstract: There is provided a method and device (2) for providing an alarm (7) on request of a person (1). The person is wearing the device that is attached with attachment means (3, 4, 5) to the wrist or other part of the body. A pulling force (6) of the person acting on the device causes a change in an electrical characteristic of a component (301) included in the device. The change of the electrical characteristic is measured and when detected will result in an activation of the alarm.

Abstract: An apparatus for capturing audio comprises a first beamformer (305) coupled to a microphone array (301) and arranged to generate a first beamformed audio output. A plurality of constrained beamformers (309, 311) each generates a constrained beamformed audio output. A first adapter (307) adapts beamform parameters of the first beamformer (305) and a second adapter (313) adapts constrained beamform parameters for the plurality of constrained beamformers (309, 311). A difference processor (317) determines a difference measure for the constrained beamformers (309, 311) where the difference measure is indicative of the difference between beams formed by the first beamformer (305) and the constrained beamformers (309, 311). The second adapter (313) is arranged to adapt constrained beamform parameters with the constraint that beamform parameters are adapted only for constrained beamformers of the plurality of constrained beamformers (309, 311) for which a difference measure has been determined that meets a similarity criterion.

Abstract: There is provided a fall detection system comprising a user device configured to be worn or carried by a user, the user device comprising a proximity sensor for measuring the proximity of the user device to the ground or a floor; and a movement sensor for measuring the movements of the user; the fall detection system further comprising a processing unit configured to process the measurements from the movement sensor to detect a potential fall; activate the proximity sensor if a potential fall is detected; and process the measurements from the proximity sensor to determine if the user has fallen.

Abstract: There is provided a method of detecting a fall by a user, the method comprising detecting whether a user has potentially experienced a fall event from measurements of the movements of the user; on detecting a potential fall event, determining the activity level of the user and a measure of a autonomic nervous system, ANS, response for the user associated with the potential fall event; comparing the determined activity level and the measure of the ANS response to a user profile relating activity level and ANS response for the user; and determining whether the potential fall event is a fall based on the result of the comparison.
