The present invention relates to a device, system and method for reliable and fast fall detection. The device comprises a sensor input () for obtaining sensor data related to movement of a subject acquired by a body-worn sensor () worn by the subject, and a video input () for obtaining video data of the subject and/or the subject's environment. An analysis unit () analyzes the obtained sensor data to detect one or more signal features indicative of a potential fall of the subject and for analyzing, if one or more such signal features have been detected, the detected one or more signal features and/or related sensor data in combination with related video data to identify similarities between: changes of the related sensor data and/or the signal features over time; and changes of the video data over time. An output () issues a fall detection indication if the level and/or amount of detected similarities exceeds a corresponding threshold.

The invention relates to a method of monitoring a plurality of vital parameters of a patientusing a body sensor network with a set of on-body sensorsand at least one off-body monitoring device, the method comprising the following steps: with each on-body sensor, sensing a vital parameter and transmitting data related to the sensed vital parameter to the off-body monitoring device, and for at least one of the on-body sensors, determining the inclination of this on-body sensorrelative to the off-body monitoring device. In this way, a reliable and easy to use possibility for monitoring vital parameters of a patientusing a body sensor network is provided that minimizes the performance problem produced by RF attenuation caused by the body of the patient

Monitoring vital parameters of a patient using a body sensor network

The present invention relates to a transceiver device for processing a medium access control (MAC) protocol used by a transceiver. The transceiver has a first antenna system for on-body communications and a second antenna system for off-body communications, the transceiver device being designed to reserve one or more data payloads for on-body communications and to allocate the first antenna system to the transceiver for the interval of time occupied by these data payloads, and/or to reserve one or more data payloads for off-body communications and to allocate the second antenna system to the transceiver for the interval of time occupied by these data payloads. An advantageous result of this is that the optimally matched antenna system is available for on-body communications and off-body communications respectively, collisions between data payloads on the radio channel being prevented within the network, and the throughput of data thus being increased and, at the same time, energy consumption being reduced for the transceiver.

Transciever device for on-body and off-body communications

There is provided a method and a device for detecting interfering radio technologies. The method in accordance with the invention is applicable in order to detect and identify possible interfering technologies that can be found, e.g., in the 2.4 GHz ISM band, by use of a device having a single transceiver which is adapted to employ a first wireless radio access technology. For example, a device having an IEEE 102.15.4 cordless transceiver is able to identify according to the method in accordance with the invention radio signals sent by disquieters which use other interfering technologies by use of only this transceiver. The device can for example be a sensor of a wireless body sensor network.

Detecting and discriminating between interference caused by different wireless technologies

The invention relates to a wireless device for medical data transmission that comprises a wireless interface, a processor, and a medical equipment interface arranged to provide connection to an item of medical equipment. The processor is arranged to communicate with the medical equipment interface and the wireless interface, and is also 5 arranged to perform a protocol adaptation. The protocol adaptation takes place from a protocol of incoming data received at the medical equipment interface to a protocol of data to be transmitted through the wireless interface, or vice versa. The protocol adaptation comprises individual or combined filtering, gathering, partitioning, prioritizing, or discarding the incoming data. The processor is further arranged to read a configuration file containing an 10 adaptation specification that pertains to the protocol adaptation; and to perform the protocol adaptation in compliance with the adaptation specification. The invention also relates to a method for setting up the wireless device.
