摘要:
There is provided a fall detection and/or prevention system, comprising one or more sensors for detecting characteristics of movement of a user of the fall detection and/or prevention system and for generating corresponding signals; processing means for analyzing the signals from the one or more sensors using a fall detection algorithm to determine if a fall has taken place or is likely to take place; wherein the processing means is further adapted to update said fall detection algorithm based on the result of the analysis of the signals and an indication whether a fall has actually taken place from the user or a third party.

摘要:
To improve the power efficiency of a monitoring system, especially for worn devices, the present invention provides a monitoring system (300) comprising a physiological signal monitor (310) configured to monitor at least one physiological signal; a processor (320) configured to receive the output signal of the physiological signal monitor and detect an abnormal occurrence of at least one physiological signal; and a movement detection sub-system (330) coupled to receive the output signal of the processor and configured to monitor the movement of a target body, based on the output signal of the processor, for detecting the abnormal situation. The power consumption of the whole system can be decreased by using the monitoring result of physiological signals as a trigger for the movement detection sub-system.

There is provided a fall detector for detecting a potential fall by a user, the fall detector comprising a sensor for measuring the skin conductivity of the user; and a processor for analyzing the skin conductivity measurements to determine whether the user has had a potential fall, wherein the processor is configured to analyze the skin conductivity measurements by matching the skin conductivity measurements to a predetermined skin conductivity response corresponding to a stressful event.
摘要:
The power used by a user in performing the vertical component of a movement is estimated. An accelerometer attached to a user measures the acceleration experienced by the user during movement. A processor configured to receive the measurements of the acceleration from the accelerometer, be attached to the user, estimate the vertical accelerations from the received acceleration measurements, and estimate the power used from the vertical accelerations.
摘要:
The reliable and controlled allocation of network elements particularly medical sensors (2) to a network (4) without prior configuration of the wireless sensors or of the network administration system can be carried out using an allocation unit (1) for allocating network elements (2) to a wireless network (4), which allocation unit (1) comprises a transmitter which transmits, in a user-controlled manner, a code to a first network element (2), which code causes the first network element (2) to transmit its ID together with the code (encoded ID) so that the latter can be received by a second network element (3) which allocates the first network element (2) to its network (4).
摘要:
A secure wireless network (2) includes a network (22, 24, 26) that includes one or more wireless nodes (7, 8, 10, 12, 14, 16, 18, 20). A list (5) includes security metadata, which describes access rights or groups of access rights granted to an entity within the wireless network (2) or groups of entities within the wireless network (2).

摘要:
A device (A) is described, which is capable of being operated within a network comprising a touch interface (2) which is adapted to detect that a user (3) touches the touch interface (2) and simultaneously touches a touch interface (6) of another device (B) capable of being operated within a network, and a communication unit (1) adapted to communicate with a communication unit (5) of the other device (B) via a communication network established between the device (A) and the other device (B) when detecting that the user touches the touch interface (2) of the device (A) and simultaneously touches the touch interlace (6) of the other device (B).
摘要:
A security system for a hierarchical network (10) includes L hierarchical levels each corresponding to a security domain level (16), and a plurality of local network nodes (A, B, . . . , Z). A keying material generator (24) generates a set (30) of correlated keying material for each network node. Each set (30) of keying material is composed of L sub-sets (32) of keying material one for each security domain level (16). A set up server (34) distributes the generated sets (30) of keying material to each network node (A, B, . . . , Z) to enable the network nodes (A, B, . . . , Z) to communicate with one another at a security domain of a hierarchical level k by a use of a corresponding sub-set (32) of the security keying material.
