Two dimension RF location method and apparatus
First Claim
1. A system for generating information identifying a two-dimensional location of objects in within a space, comprising:
- a plurality of wireless modules, each of the plurality of wireless modules corresponding to one of the objects;
first and second radio transceiver systems spaced apart by a predetermined distance, the first and second radio transceiver systems disposed proximate the space, each of the first and second radio transceiver systems operable to selectively transmit a signal to select wireless module, receive a response signal from the select wireless module, and generate first information based on a detected relationship between the selective transmission and the receipt of the response signal; and
a device operable to calculate a two-dimensional location of the select wireless module based on the first information generated by the first radio transceiver system and the first information generated by the second radio transceiver system.

Abstract
A system for generating information identifying a two-dimensional location of objects in within a space includes a plurality of wireless modules and first and second transceiver systems. Each of the plurality of wireless modules corresponds to one of the objects. The first and second radio transceiver systems are spaced apart by a predetermined distance and are disposed proximate the space. The first and second radio transceiver systems are operable to selectively transmit a signal to select wireless module, receive a response signal from the select wireless module, and generate first information based on a detected relationship between the selective transmission and the receipt of the response signal. The system further includes a device operable to calculate a two-dimensional location of the select wireless module based on the first information generated by the first radio transceiver system and the first information generated by the second radio transceiver system.

10. A method of generating information identifying a two-dimensional location of objects in within a space, the method comprising:
-
a) transmitting from a first location a first signal having a parameter corresponding to a first object of a plurality of objects within the space; b) receiving a first responsive signal from the first object; c) determining first distance information based on a relationship between the first signal and the first responsive signal; d) transmitting from a second location a second signal having a parameter corresponding to the first object; e) receiving a second responsive signal from the first object; f) determining second distance information based on a relationship between the second signal and the second responsive signal; g) determining a two-dimensional location of the first object within the space based on the first distance information and the second distance information. - View Dependent Claims (11, 12, 13, 14, 15)
