International Classification:

G08B 13/14

US Classification:

3405721, 700 45, 700225

Abstract:

A method in one embodiment comprises scanning a zone in an active mode at a first power level for identifying presence of a tag; and scanning portions of the zone in a passive mode at a second power level for again identifying presence of the tag. A system in another embodiment comprises an interrogator for scanning a zone in an active mode at a first power level for identifying presence of a tag; wherein the interrogator also scans portions of the zone for again identifying presence of the tag. A method in another embodiment comprises scanning zones of an area in an active mode for identifying the zone in which the tag is located; and scanning portions of the zone in which the tag is located in a passive mode for identifying the portion of the zone in which the tag is located.

International Classification:

H04Q 5/22

US Classification:

340 101, 3405721, 34053922, 340 105, 34053926, 455 85, 455 86

Abstract:

A system according to one embodiment of the present invention includes a first clock signal generator generating a first clock signal at a first frequency, and a second clock signal generator generating a second clock signal at a second frequency that is higher than the first frequency. The first clock signal is used to calibrate the second clock signal generator. An RFID device according to another embodiment of the present invention includes a crystal controlled first clock signal generator generating a first clock signal at a first frequency, a second clock signal generator generating a second clock signal at a second frequency that is higher than the first frequency, and an activate circuit. The second clock signal generator is inactive until activated by the activate circuit. The first clock signal is used to calibrate the second clock signal generator.
