Abstract: There is presented a wearable device (200) and corresponding system and method for sensing a substance ingested by a subject, for instance an intoxicating substance. The wearable device has a sensing arrangement extending between a first port (205a) and a second port (205b). The sensing arrangement includes two chambers, a pump and two flow-control devices. The first chamber is adapted to collect gas from a skin region of the subject. The second chamber has a sensor to sense the substance. The first flow-control device is provided at the first port (205a) and the second flow-control device is provided at the second port (205b). A controller is provided to control the pump and the sensor. The controller is operable in a first phase to sense a first gas sample from ambient environment, and a second phase to sense a second gas sample from a skin region of the subject.

Abstract: The disclosure relates to a wearable device 200 for tracking a subject. It includes a flexible member attachable on a limb of the subject, an electronic circuit 210 and a connector 230. The flexible member has a first portion 220a comprising a first set of conducting channels, and a second portion 220b comprising a second set of conducting channels. The electronic circuit 210 is coupled to the first portion and the second portion. The connector 230 is adapted to connect the first portion to the second portion. Upon connection at least one channel from the first set is connected to a channel from the second set to obtain a channel connection.

Abstract: The application relates to a chemical monitoring system comprising a skin patch for detecting an analyte in perspiration and a processor adapted to receive parameter data and to return an output indicative of a presence of an analyte in a subject's body based on the parameter data. The skin patch (100) includes a first layer (105) permeable to perspiration; a second layer (110) coupled to the first layer, the second layer being adapted to receive the perspiration; wherein a property of the second layer changes upon receiving the analyte; an electrical detector coupled to the second layer, adapted to detect parameter data indicative of the property of the second layer; and a flexible electronic circuit (140) coupled to the second layer, comprising a readout circuit for reading parameter data from the electronic detector and a transmitter adapted to transmit the parameter data to a processor.

Abstract: A skin patch for use on a skin portion of a subject. The skin patch includes an analyte detector that detects an analyte from perspiration. The skin patch is adapted to release a marking agent such as a dye to mark the skin portion upon detection of the analyte.

Abstract: A portable identification device comprises a biometric recognition system in combination with GPS or equivalent receivers for carrying out identification checks. The device is a basic portable unit.

Abstract: An ingestion monitoring system (100) comprising: one or more acoustic transducers (102); an analogue to digital converter (208) arranged to convert electrical signals from the acoustic transducer to digital form; and a processor (210) arranged to process the digital signal to detect an ingestion event.

Abstract: An activity monitor comprising one or more acoustic transducers (100) and a computation component (104) that is arranged to identify events from acoustic signals received by the acoustic transducers (100).

Abstract: A computer-implemented method comprises: receiving (100) first information indicative of a tracking device being located in a particular place, for example by detecting that the tracking device is connected to a charging station for charging; receiving (102) second information, from a passive detecting means, indicative of the user of the tracking device leaving said place, for example based on sounds that the user has made in leaving; (104) determining, based on the first and second information, that a user of the tracking device leaves said place while the tracking device remains in said place; further to said determining, causing (106) at least one separation related action to be performed, for example sending a message to a remote server (14).

Abstract: A method comprising maintaining (A, B), by a device (6), communication with a monitoring unit (7); determining, by the device, an absence of communication from the monitoring unit; based at least on a result of said determining, starting monitoring (F) of at least one variable related to distance moved by the device and/or time elapsed; if the at least one variable meets at least one criterion, determining that the absence of communication from the monitoring unit is not due to a blind spot. A device securely attachable to a person (5) may be configured to carry out this method, which may be user in offender monitoring.
