Monitoring of vital body signals during movement

In a multi-sensor system and method of monitoring vital body signals during movement of a body of a human or an animal, acceleration sensors are placed at body locations in such a way that an acceleration angle change induced by the vital body signals differs between the at least two acceleration sensors. The retrieval of the vital body signals is achieved by extracting a wanted vital body signal based on measurement results from multiple sensors that may be motion contaminated. Three retrieval schemes are proposed, each with preferred sensor locations that provide optimal performance of retrieving the vital body signal(s).

The present invention is directed to multimodal communications means for transmitting signals representing physiological, performance, and contextual information associated with a subject. In an exemplary embodiment, the multimodal communications means includes multiple radio subsystems (or modes) that enable connection to an external monitoring device to be acquired in a wide range of settings where a single radio mode would be ineffective. Additionally, combining the multimodal communications means of the invention with real-time data-processing allows the communications functionality to be engaged only when data determined to be relevant to the user is identified.
