Abstract: Methods, a system, a network of nodes and at least one wearable device. The at least one wearable device is adapted to be worn by individuals and are configured to transmit short-range wireless broadcast signals while a short-range wireless connection between the wearable device and a node of the network of nodes is active. At least one of the network nodes is configured to initiate the establishment of an internal transmission channel or path within the network for routing sound recorded by a microphone of the wearable device as audio data to the network node assigned to receive incoming, to the network, and forward outgoing, from the network, audio data from a conference call or call in which a particular wearable device is to participate.

Abstract: Methods, a system, a network of nodes and at least one wearable device, where the at least one wearable device is adapted to be worn by individuals and are configured to transmit short-range wireless broadcast signals while a short-range wireless connection between the wearable device and a node of the network of nodes is active. A network node initiates the establishment of an internal transmission channel or path within the network for routing sound recorded by a microphone of the wearable device as audio data to the network node assigned to receive incoming, to the network, and forward outgoing, from the network, audio data from a conference call or call in which a particular wearable device is to participate. The network node mutes the microphone or audio data obtained by the microphone in response to detecting certain voice activity in audio data incoming to the network node.

Abstract: Methods, a system, a self-organizing network of nodes and at least one portable personal device is provided. The at least one personal device is adapted to be worn by individuals and is configured to transmit short-range wireless broadcast signals. The personal device is configured to establish a short-range wireless communication link with the nodes of the self-organizing network and to enable the establishment of a short-range wireless communication link with a mobile communications device which may be associated with the personal device. The network and the personal devices are further configured to enable handover of the personal device between a node of the self-organizing network and a mobile communications device which may be associated with the personal device.

Abstract: A monitoring system, a wearable device, a network and methods for activating a sensor in a wearable device carried by an individual and connected to the network are provided. More specifically, a system for monitoring individuals, and a wearable device for activating a sensor of the wearable device in response to input data and/or sensor data obtained by the wearable device is indicating certain events or changes in the behavior or condition of the individual carrying the wearable device.

Abstract: Methods, a monitoring system, a self-organizing network of nodes and a plurality of portable personal devices. The assignment of roles for the network nodes is associated with a specific individual personal device and is done on two levels, control level and connect level. The role assigned to a network node may be dynamically changed based on data obtained by the personal devices and/or the node network.

Abstract: Methods, a system, a self-organizing network of nodes and a plurality of portable personal devices are disclosed. The personal devices are adapted to be worn by individuals and are configured to transmit short-range wireless broadcast signals while a short-range wireless connection between the personal device and a node of the network of nodes is active. The controller node assigned to a personal device may then be configured to determine the position or location of the individual and take actions on behalf of the individual wearing the personal device in response to received data contained in broadcast signals forwarded by other nodes and/or status data, sensor data and/or event data received and forwarded to the controller node by the connection node assigned to the personal device.
