| 20080258878 | FACILITATING RFID TAGS TO REFRAIN FROM PARTICIPATING IN A SUBSEQUENT INVENTORYING ATTEMPT - RFID reader systems, readers, components, software and methods can inventory RFID tags in one or more early attempts. Then they can facilitate the inventoried RFID tags to refrain from participating in one or more subsequent inventorying attempts. In some embodiments, an inventoried indicator in the tag becomes updated upon backscattering. The updated value is used by the tag to recognize a subsequent attempt, and thus refrain from participating in it. This permits the subsequent attempt to be used more intensively for inventorying the more elusive, harder-to-read tags, especially in more demanding scenarios. | 10-23-2008 |

| 20090121843 | METHOD AND SYSTEMS FOR LOCALIZING OBJECTS USING PASSIVE RFID TAGs - Method and system for localizing an object in a stack of objects. A passive radio frequency identification (RFID) tag is attached to each object. Each RFID tag includes a unique identifier of the object to which the RFID tag is attached. A RFID reader has multiple antennas. Each antenna is positioned to transmit a signal that can be detected by different RFID tags attached to the objects within a reading range of the transmitted signal from each antenna. The antennas are sequentially selected and powered to transmit to the stack a read signal including object's identifier for the object to be localized. If a response to the read signal is received by a selected and powered antenna from a RFID tag that matched the object's identifier with its unique identifier, then a light emitting diode (LED) is lighted to identify a location of the object being localized. | 05-14-2009 |
