摘要： An interrogator, methods of discerning the presence of an object, and interrogation systems employing the same. In one embodiment, the interrogation systems include multiple interrogators that communicate with a base command unit to track a location of an object. In another embodiment wherein the object is an RFID object (e.g., an object with an RFID tag), the interrogators employ signal processing techniques such as precharging the RFID object, and correlating a reference code with a reply code from the RFID object using selected techniques to increase a sensitivity of the interrogator, especially for adverse environments. In other embodiments, the interrogation systems include variations of metal instruments and sponges employed therewith. In yet another embodiment, the interrogation system includes metal interrogators capable of discerning the presence of a metal object, especially in a presence of another metal object.

摘要： A reply code for a radio frequency identification (RFID) tag, a method of improving a reply code for a radio frequency identification (RFID) tag for interrogation by an interrogator and an RFID tag employing the same. In one embodiment, the reply code includes a preamble having information about a quality of a clock associated with the RFID tag. The reply code also includes a tag identification (ID) code providing a digital signature for the RFID tag. The reply code still further includes an aftamble located aft of the preamble and having information about the quality of the clock. The aftamble cooperates with the preamble to improve a quality of the reply code for interrogation by an interrogator.
