System and method of occupancy estimation utilizing transmitted signals
First Claim
Patent Images
1. A method of estimating a number of occupants located in a region, the method comprising:
- receiving at one or more receiving units a signal transmitted from one or more transmitting units, wherein the transmitting units are not associated with the one or more occupants located in the region;
measuring one or more attributes of the received signal; and
estimating the number of occupants located in the region based, at least in part, on the one or more measured attributes of the received signal, wherein the number of occupants is estimated by comparing the measured attributes of the received signal or functions of the measured attributes to a theoretical model that describes a relationship between measured attributes of the received signal or functions of the measured attributes and number of occupants in the region.

Abstract
A method estimating number of occupants in a region includes receiving at one or more receiving unit a signal or signals transmitted from one or more transmitting units, wherein the transmitting units are not associated with the one or more occupants located in the region. In addition, the method includes measuring one or more attributes of the received signal for a duration of time and calculating an occupancy estimate based, at least in part, on the measured attribute of the received signal.

14. An occupant estimation system comprising:
-
at least one transmitting unit that transmits a signal; at least one receiving unit that includes an antenna for receiving the signal; at least one signal measurement unit that measures one or more attributes associated with the received signal; a memory unit that stores a theoretical model, wherein the theoretical model describes a relationship between the one or more measured attributes of a received signal or functions of the one or more attributes of the received signal and various numbers of possible occupants; and a processor that implements an occupancy estimation unit, wherein the occupancy estimation unit compares the one or more measured attributes or functions of the measured attributes of the received signal to the theoretical model to generate an estimate of the number of occupants in a region. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
