Systems within a position locator device for evaluating movement of a body and methods of operating the same
DC
First Claim
1. A system within a position locator device capable of evaluating movement of a body relative to an environment, said system comprising:
- a sensor, associable with said body, that senses dynamic and static accelerative phenomena of said body; and
a processor, associated with said sensor, that processes said sensed dynamic and static accelerative phenomena as a function of at least one accelerative event characteristic to thereby determine whether said evaluated body movement is within environmental tolerance.

Abstract
The present invention introduces systems, as well as methods of operating such systems, within a position locator device for evaluating movement of a body relative to an environment. According to an exemplary embodiment, the system comprises a sensor and a processor. The sensor, which is associable with the body, is operable to repeatedly sense accelerative phenomena of the body. The processor, 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 system, and, more particularly, the processor generates state indicia relative the environment, and determines whether the evaluated body movement is within environmental tolerance. In a preferred embodiment, the processor communicates various state indicia to a monitoring controller, preferably using at least one of a wired network and a wireless network. The monitoring controller cooperates with the processor to remotely monitor the body.

- 21. A method of operating a system within a position locator device to evaluate movement of a body relative an environment wherein a sensor is associated with said body, said method of operating comprising the step of processing, with a processor, repeatedly sensed dynamic and static 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 environmental tolerance.
-
25. A method of operating a system within a position locator device to distinguish accelerative phenomena of a body comprising the steps of:
-
substantially continually measuring dynamic and static acceleration of the body in plural axes at a sensor maintained on the body and providing output signals indicative thereof; and
processing said output signals to distinguish between normal accelerative events and abnormal accelerative events based upon both said dynamic and said static acceleration of the body. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32)
