Abstract: There is provided a device and a method for detecting exit of a person from a room, the device comprising: means for detecting door opening and closing; movement detection means for detecting movement in the room; and a processing circuitry configured to initiate processing of measurement data from the movement detection means as a response to detecting the door closing, and to cause an output of a message concerning the processing of said measurement data.

Abstract: This document discloses a mobile key for a locking system, the mobile key comprising: a wireless communication circuitry configured to communicate wirelessly with a locking device of the locking system; a memory storing authentication information associated with access rights of the mobile key in the locking system. The mobile key further comprises a radio frequency trigger circuitry sensitized to detect a radio signal received in the mobile key and, upon detecting the reception of the radio signal, to wake up the wireless communication circuitry to communicate with the locking device.

Abstract: This document presents a location tracking system comprising a plurality of location tracking nodes disposed to cover an area where the location tracking is to be carried out, at least one mobile tag configured to communicate with at least one of said plurality of location tracking nodes at a time for location tracking purposes, and a control apparatus configured to control operational parameters of the plurality of location tracking nodes and the at least one mobile tag. The control apparatus and the plurality of location tracking nodes are configured to carry out an automatic calibration phase during operation of the location tracking system the location tracking nodes transmit and receive test signals between the neighboring nodes, and report measurement results to the control apparatus. The control apparatus then optimizes the operation parameters of the location tracking system on the basis of received measurement reports.

Abstract: There is provided a system for carrying out a height calibration process in a wireless indoor location tracking network, comprising: a plurality of fixed location tracking nodes disposed indoors to cover an indoor area, wherein the plurality of fixed location tracking nodes is configured to carry out location tracking in the indoor area; a mobile tag configured to communicate with at least one location tracking node at a given time at least for the purposes of determining the location of the mobile tag, wherein that the mobile tag comprises a height sensor configured estimate the height of the mobile tag; and at least one location tracking node of the plurality of fixed location tracking nodes is a calibration node configured to co-operate in carrying out a height calibration process during operation of the location tracking network, wherein the height of each calibration node is known.

Abstract: A method, apparatus, and computer program for operating a Bluetooth network is presented. The method comprises providing a Bluetooth system comprising a plurality of Bluetooth devices forming Bluetooth piconets disconnected from each other; and providing a route for a data packet between two remote Bluetooth devices through the Bluetooth system by sequentially changing structures of the Bluetooth piconets, wherein at least some of the plurality of Bluetooth devices sequentially create and terminate connections with different Bluetooth devices as a result of the sequential change of the structures of the Bluetooth piconets.

Abstract: The present invention provides a method for changing a usability status of an asset in a location tracking system. Establishment of a direct device-to-device wireless communication connection between a user tag and an asset tag of the location tracking system triggers a process to change a usability status of the asset associated with the asset tag. In the process, identifiers of the asset tag and the user tag obtained when pairing the asset tag and the user tag are used in order to link the user tag with the asset tag in the process for changing the usability status of the asset.

Abstract: An apparatus enabling establishment of a Bluetooth mesh network comprises at least two Bluetooth transceiver circuitries and an internal connection between the at least two Bluetooth transceiver circuitries. The Bluetooth transceiver circuitries are simultaneously connected to different Bluetooth piconets, and the apparatus operates as a bridge between the piconets. Concatenation of such apparatuses enables construction of a Bluetooth mesh network where the bridge devices may be simultaneously connected to multiple Bluetooth piconets.

Abstract: This document presents a location tracking system. Transmitter tags are disposed throughout the area where the location tracking is carried out. The transmitter tags are configured to transmit their unique identifiers. A personal radio communication device being tracked detects a unique identifier received from a transmitter tag and transmits the detected unique identifier to a server. The server links a known physical location associated with the unique identifier to an identifier of the personal radio communication device so as to carry out location tracking.
