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: 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.

Abstract: A fall detection system is provided, which includes at least one processing device, at least one personal module including a personal module pressure sensor, and at least one reference module including a reference module pressure sensor. The at least one processing device is arranged to receive personal pressure data from the at least one personal module pressure sensor, receive reference pressure data from the at least one reference module pressure sensor, determine a personal pressure using the personal pressure data and the reference pressure data, determine an individual personal pressure profile based on the historical personal pressure of the individual, compare the personal pressure with the individual personal pressure profile, which may e.g. be an individual personal pressure threshold, and set a fall detection alert based at least on whether the personal pressure lies beyond the individual personal pressure profile, e.g. by being above the individual personal pressure threshold.
