Abstract: An electronically controlled door latch for a motor vehicle, the electronically controlled door latch being configured for operating in at least three different operation conditions including a normal operating condition, a sleep operating condition and a crash operating condition, and comprising a system basis chip configured for receiving a main supply voltage from a main power source of the motor vehicle during the normal operating condition and a backup supply voltage during the crash operating condition, an electric motor configured for actuating the electronically controlled door latch based on the main supply voltage (Vbatt) during the normal operating condition and on the backup supply voltage during the crash operating condition, and an electronic control unit configured, when being triggered by the system basis chip, for falling asleep during the sleep operating condition and for being wakening up during the normal operating condition and the crash operating condition and configured for controlling

Abstract: The present invention is directed toward the recovery of RFID signals from RFID credentials. The recovery and subsequent interpretation of RFID signals may be accomplished by providing a set of predetermined probabilities for the occurrence of a symbol after another symbol in a received signal. The predetermined probabilities may be dependent only upon the encoding scheme used, thereby providing a more robust and less processor intensive decoding protocol than has previously been contemplated.

Abstract: A radio frequency identification (RFID) system is described, including a low frequency read-write device (1B) comprising an antenna (2B) connected to a transceiver (4B), for receiving/transmitting low RF waves from/to an RFID tag (5B), and a decoder (3B) for decoding said low RF waves into digital data (dig-B); an host computer (20) is intended to be connected to the low frequency read-write device (1B) for processing digital data (dig-B). The RFID system further includes a high frequency read-write device (1A), comprising an antenna (2A) connected to a transceiver (4A), for receiving/transmitting high RF waves from/to an RFID tag (5A), and a decoder (3A) for decoding said high RF waves into digital data (dig-A); the high frequency read-write device is connected to a low frequency read-write device (1B) and to an host computer (20) respectively through a driver connection (22) and an host connection (21).

Abstract: The invention relates to a radio frequency (RF) system and method for improving the detection efficiency of an identification system including a transponder and a reader. The system (1) comprises an interrogator reader device (3) having an interrogator coil antenna (4) and a transponder (2) having a transponder coil antenna (5) and a microchip (6) Advantageously, the interrogator reader device (3) comprises a detection portion (11) including a sensitive signal gain detector (SSGN) for detecting just the presence of the transponder coil antenna (5) in case of misplacement of the transponder or broken link between the transponder coil antenna (5) and the microchip (6). The invention allows remedying to those potentially dangerous situations that might lead to a misdetection of the transponder (2).

Abstract: Radio frequency identification (RFID) system comprising a read-write device 1, including a memory unit 3 for storing a plurality of basic opcodes ba-op, an RFID tag 5, including a memory unit 8 for storing data item and a plurality of opcodes cr-op; the basic opcodes ba-op and opcodes cr-op drives the communication between the read-write device 1 and the RFID tag 5 according to a standard air interface. The memory unit 3 comprises a mapping function fx for transforming said basic operands ba-op in said operands cr-op; the opcodes cr-op are in crypted format and the mapping function fx authorises the communicative connection between the RFID tag 5 and the read-write device 1. The memory unit 3 also comprises a plurality of optional operating codes opt-op and the memory unit 8 also comprises a plurality of further optional operating codes opt-cr-op in crypted format. The mapping function fx also transforms the optional operating codes opt-op in such further optional operating codes opt-cr-op.
