Abstract
Method for identifying a location of a subject in a facility and a corresponding system including a kinematic sensor configured to detect a change in subject's mechanical characteristic, and a communications unit. Communications unit includes a controller configured to receive feedback from the kinematic sensor and a unit transceiver controlled by the controller to transmit a first radio frequency (RF) signal communicating the change. The system may include a housing facilitating coupling of the kinematic sensor with the subject, and at least one facility transceiver unit arranged in a fixed location to extract the first RF signal relative to an RF pattern and to produce an output signal. A processor is configured in communication with the facility transceiver unit (wirelessly or over the facility's power wire) to receive the output signal and to generate data representative of a location of the subject relative to the fixed location.
