System and method for detecting motion of a body
First Claim
1. A system that evaluates movement of a body relative to an environment, said system comprising:
- a sensor, associable with said body, that senses accelerative phenomena of said body relative to a three dimensional frame of reference in said environment, said sensor comprising a plurality of acceleration measuring devices; and
a processor, associated with said sensor, that processes said sensed accelerative phenomena of said body as a function of at least one accelerative event characteristic to thereby determine whether said evaluated body movement is within an environmental tolerance, and to thereby determine whether said body has experienced acceleration that represents one of a plurality of different types of motion.

Abstract
The present invention comprises a system and method for detecting an acceleration of a body and for evaluating movement of a body relative to an environment to detect falls and irregular motions of the body. According to an exemplary embodiment, the system comprises a sensor and a controller that comprises a processor. The sensor, which is associable with the body, comprises a plurality of acceleration measuring devices and is capable of repeatedly sensing accelerative phenomena of the body. The controller, which is associated with the sensor, is operable to process the sensed accelerative phenomena as a function of at least one accelerative event characteristic. The controller determines when the body experiences an acceleration that represents a particular type of motion. The controller also determines when a static acceleration vector reaches a value indicative of a fall. After a fall has occurred, the controller is capable of determining whether the controller was connected to a body during the fall or whether only the controller experienced the fall.
