US Patent:

20110043373, Feb 24, 2011
Filed:

Aug 20, 2009
Appl. No.:

12/544869
Inventors:

Gregory C. Best - San Francisco CA, US
Andrew Ansell - Santa Clara CA, US
Gwen Byard - Mountain View CA, US
James W. Jervis - Sunnyvale CA, US
Jeffrey D. Sanders - San Jose CA, US
Assignee:

Trimble Navigation Limited - Sunnyvale CA
International Classification:

G06K 7/02
US Classification:

34082549
Abstract:

A reverse RFID location system is based on set of RFID tags in which each tag stores data representing its position.

US Patent:

20160116565, Apr 28, 2016
Filed:

Dec 22, 2015
Appl. No.:

14/979205
Inventors:

- Sunnyvale CA, US
Andrew Ansell - Santa Clara CA, US
James M. Janky - Los Altos CA, US
International Classification:

G01S 5/02
G01S 13/74
Abstract:

A radio frequency identification (RFID) tag distance measuring system and method is disclosed. One example includes a first replica path that receives a signal that is simultaneously transmitted to an RFID tag. The first replica path includes a plurality of taps at known distances along the first replica path. Each of the plurality of taps has a first tap input coupled with the first replica path. In addition, an RFID signal receiver receives a return signal from the RFID tag and provides the return signal along a measurement input, wherein each of the plurality of taps have a second tap input coupled with the measurement path. A distance determiner detects at least the first of the plurality of taps to have an output and determine a distance measurement to the RFID tag based thereon.
