Identification of a subject in a facility

摘要

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.

1. A system for identifying a location of a subject relative to a facility, the system comprising:
a kinematic sensor configured to detect a change in at least one of position, velocity, and acceleration thereof; a communications unit including:
a controller configured to receive feedback from the kinematic sensor; anda unit transceiver controlled by the controller to transmit a first radio frequency (RF) signal representing the change in at least one of position, velocity, and acceleration; a housing structured to facilitate coupling of the kinematic sensor with the subject; at least two facility transceiver units in corresponding fixed locations, said at least two facility transceiver units configured to extract the first RF signal, relative to RF signal patterns that are caused by reflection and scattering of said first RF signal off of objects in the facility and that reduce a signal-to-noise ratio of said first RF signal, to produce an output signal; and a processor in operable communication with the at least two transceiver units, the processor configured to receive the output signal and generate data representative of a location of the kinematic sensor relative to the corresponding fixed locations.
