摘要： An RFID transponder is provided which includes an automatic gain control (AGC) stage for amplifying a radio frequency (RF) signal and for providing an amplified RF signal. The AGC stage has a control signal indicating an increase of the amplitude of the RF signal. A demodulator is coupled to receive the amplified RF signal for demodulating the amplified RF signal. The demodulator provides a data signal. A burst detector is coupled to receive the control signal of the AGC stage and adapted to provide a start signal in response to a change of the control signal. A wake pattern detector is coupled to receive the data signal and the start signal. The wake pattern detector is adapted to detect a predefined wake pattern in the data signal after having received the start signal and to issue a wake signal if the predefined wake pattern is detected for switching the RFID transponder from a first operating mode into a second operating mode having higher power consumption than the first operating mode.

摘要： A passive entry system receives an electromagnetic interrogation signal transmitted from an interrogation antenna to a remote transponder, wherein the interrogation signal includes a wakeup pattern data sequence. A plurality of channel signals is generated within the transponder from a corresponding plurality of antennas in response to the electromagnetic interrogation signal. Bit detection is performed on each of the plurality of channel signals to detect the wakeup pattern sequence. A received signal strength indicator (RSSI) of the interrogation signal is determined using the plurality of channel signals, wherein only channel signals on which a valid wakeup pattern sequence is detected are used for determining the RSSI. A wakeup signal is asserted to wake up a processing module in the remote transponder only when the wakeup pattern sequence is detected on at least one of the plurality of channel signals.

摘要： Apparatus and method of identifying a plurality of transponders (10-16) entering into an inquiry field (18) of an interrogation unit (20) are provided. The transponders (10-16) are each assigned a unique identification code. Upon receipt of an interrogation pulse from the interrogation unit (20), each transponder (10-16) responds with its respective identification code. Depending on the spatial distance of each transponder (10-16) with respect to the interrogation unit (20), the interrogation unit (20) detects and receives the strongest response. The received identification code is stored. The interrogation unit (20) repeatedly sends interrogation pulses containing any stored identification code until all of the transponders (10-16) are identified and read.

摘要： A system and method for providing a fuel dispenser with radio frequency customer identification capabilities. The system and method determines whether a transponder containing customer identification data is within range of a dispenser, the dispenser requiring activation by the customer to initiate a transaction and including a reader associated therewith for emitting radio frequency signals within the dispenser range, and for receiving customer identification data from the transponder responsive to the emitted radio frequency signals received by the transponder. When the transponder is within range of the dispenser, an in-range indication is provided to the customer. A determination is made whether the dispenser has been activated by the customer following a determination that the transponder is within the dispenser range. Upon activation of the dispenser following the determination that the transponder is within the dispenser range, the customer identification data received by the reader is associated with a transaction at the activated dispenser, whereupon the transaction at the activated dispenser is permitted and charged to the customer according to the customer identification data. The system easily retrofits onto an existing, conventional fuel dispenser.

摘要： A corrected digital response signal is generated from a corrupted transponder response signal by receiving the response signal an odd number of times, greater than one, and sampling each received response signal a predetermined number of times. Then, the sample values from each transponder response signal are compared to one another and a majority sample value is obtained. The majority sample value is the value ordained by the majority and therefore represents the corrected response signal value. Alternatively, if time does not permit reception of more than one transponder response signal, additional response signals may be generated from the originally received response signal by shifting the received response by a predetermined number of samples to the right and by shifting the received response by a predetermined number of samples to the left to generate second and third response signals. Then, as similarly described, the first second and third signals are compared sample by sample with the majority sample value yielding the corrected sample value. In this way, a corrected response signal is generated.

摘要： A transponder unit (10) includes an N cycle counter (30) and an M cycle counter (28). The N cycle counter (30) has a different cycle value than the M cycle counter (28). During the transmission of information from the transponder unit (10), the duration for data bits having a binary zero value is controlled by the N cycle counter (30). The duration of data bits having a binary one value is controlled by the M cycle counter (28). The use of different cycle values within the N cycle counter (30) and the M cycle counter (28) allows for the transmission of binary one and binary zero data bits having the same bit length despite different frequencies representing the binary one and binary zero bits respectively.
