20100060430 | Enhanced RFID Output Control - A method, system, and an apparatus are provided for enhanced RFID system output control. A carrier field of an RFID reader is switched on in a controlled manner. A response signal from a passive RFID transponder located in the carrier field is received at the RFID reader. The response signal comprises a code related to the RFID transponder. Said code is detected and a time difference is determined between the switching on of the carrier field and the detection of the code signal. Said time difference provides a measure for the distance between the RFID transponder and the RFID reader. | 03-11-2010 |
20100073145 | RFID Reaction Time Reduction - A method, system, and a control device are provided for reducing RFID reaction times. A control unit receives a data signal, which comprises a code signal if a passive RFID transponder is located in the carrier field of an RFID reader. The code represents the identification code of the passive RFID transponder. The carrier field is disabled to reset the data signal, and thereafter enabled to receive a first portion of the code signal only. The code of the passive RFID transponder is then validated on the basis of said first portion of the code signal only. | 03-25-2010 |
