摘要： A method and device enables improving a signal to noise ratio (SNR) of a backscatter signal received from a radio frequency identification (RFID) tag. The method includes generating a continuous wave (CW) carrier signal at the reader device (step 505). An amplitude modulation (AM) noise component of the CW carrier signal is then detected (step 510). The AM noise component is inverted to an inverted noise signal (step 515), and the inverted noise signal is summed with the CW carrier signal to provide an AM noise cancelled carrier signal (step 520). The AM noise cancelled carrier signal is then transmitted from an antenna of the reader device (step 525), and the backscatter signal is received at the reader device in response to transmission of the AM noise cancelled carrier signal (step 530).

The apparatus comprises a communicator coupled to the mobile terminal for instructing the terminal to enter a LOCATE mode, an RFID transceiver in the terminal that interrogates RFID tags while in the LOCATE mode to obtain information therefrom correlatable with their known positions, and a processor coupled to the RFID transceiver for determining the terminal location based at least in part on such information. Location determination may take place either in the terminal or a local network server or both. The tags may be either fixed position infrastructure tags or item tags that have been mapped in the local server or the terminal. Once the terminal location is determined, the terminal and/or server may announce and/or broadcast the terminal location.

摘要： A thermal management system and method to control temperature in an RFID reader is described herein. In particular, by inserting variable periods of inactivity (or latency) at the beginning or at the end of each read cycle, proportional to an instantaneous temperature value of the RFID reader, over-heating and damage of RFID reader electronics is prevented. The RFID reader includes a thermal sensor and determines when the high power RF electronics is enabled. If the RFID reader is in an over-heated condition, it can be turned OFF and during this period any requests received on an interface to the RFID reader to perform a read of tag(s) are not processed.

摘要： A multi-resolution object location system and method for locating objects is provided. The multi-resolution system and method uses a long-range object locator together with a more precise RFID locator to efficiently and accurately determine the location of objects that include an RFID tag. The long-range object locator has a relatively longer range and can cover a relatively large area to determine the general location of the object within the large area. The RFID locator has a relatively shorter range, but is able to locate the object more precisely. The object location system uses the long-range locator to first determine the general location of the object, and then the RFID locator is used to determine a more accurate location of the object. Thus, the multi-resolution object location system is able to provide both a long range location of objects over a large area and a precise location of objects.

摘要： A method and device enables reading radio frequency identification (RFID) tags in a localized area. The method according to one embodiment includes commencing transmission of an interference signal from a reader device (step 505). A command signal is then transmitted from the device while the interference signal is still being transmitted (step 510). The command signal instructs non-target RFID tags to not respond to an interrogation signal, and the target RFID tags do not process the command signal because the command signal is blocked by the interference signal. Transmission of the interference signal from the device is then stopped (step 515). The interrogation signal is then transmitted from the device after the interference signal is no longer being transmitted (step 520). Finally, a response signal is received at the device from the target RFID tags that enables the device to read only the target RFID tags (step 525).
