摘要： Encoder and decoder microchips suitable for use in remote control devices, are disclosed. The encoder microchip comprises means for performing an encoding function (7) on an identification number (16) embedded in the said microchip and a combination of a unit number and a stepping counter value, so as to generate a transmission value which is only decodable by a related decoding function having access to the same identification number. The decoder microchip comprises means for decoding the transmission value into a decoded unit number and a decoded counter value and means for comparing the decoded counter value with a decoder counter value range (17-20). The encoder and decoder microchips are provided with means for changing, e.g., in a preferred mode incrementing, the counter values by a number greater than one after a period of time, subsequent to the encoder microchip being activated or the decoder microchip receiving a transmission value. The encoder and decoder microchips are also provided with means for synchronizing the decoder microchip with a particular encoder microchip which has generated a synchronization command.

摘要： A passive keyless entry system is specifically adapted for use with automotive vehicles. The system is designed to auto­matically unlock the vehicle (10) as the operator (12) approaches the vehicle. The system is further designed to automatically lock the vehicle as the operator carrying the beacon (24), moves away from the vehicle. The system includes a portable beacon that is carried by the operator, a receiver/controller (100) located in the vehicle, and an antenna connected to the receiver/con­troler (100) for receiving the encoded transmission from the beacon. The beacon includes a motion sensor to conserve battery life when the beacon is stationary. Transmission between the beacon and the receiver/controller is characterized by a magnetically coupled radio frequency signal embodying differ­ential phase encoded data with error correction coding of data to enhance noice immunity and signal discrimination.

摘要： The invention concerns a motor vehicle locking system, comprising at least one key (30) co-operating with a device controlling (10) the locking/unlocking of the vehicle doors with an open-ended code consisting of a first basic keyword (Cb) and a second pseudorandom keyword (Ni) and with an identification device (20), wherein the re-synchronisation of the open-ended code between the key and the control device is characterised in that on receiving a code for locking/unlocking the doors which does not correspond to the expected code, the control device stores the code received and updates its second keyword image on the basis of the code received if the identification device confirms positive identification of the key.

摘要： Die Erfindung betrifft eine Vorrichtung zur Aktivierung und/oder Deaktivierung einer Sicherheitseinrichtung, insbesondere einer Zugangseinrichtung für ein Kraftfahrzeug, mit einer tragbaren Sendeeinheit zum drahtlosen Senden einer codierten Information, welche von einer Empfängervorrichtung empfangen und mit einer vorgegebenen codierten Information verglichen wird, wobei von der Empfängervorrichtung im Fall der Übereinstimmung beider Informationen ein Ansteuersignal an die Sicherheitseinrichtung abgebbar ist, und die Sendeeinheit und die Empfängervorrichtung hinsichtlich der aktuellen codierten Informationen weiterschaltbar sind.
Bei einer Vorrichtung, bei welcher ein unbefugtes Deaktivieren der Einrichtung sicher verhindert wird, erfolgt eine n-fache Weiterschaltung in der Sendeeinheit (1) und in der Empfängervorrichtung (2) nach einem vorgegebenen Zeitraum selbsttätig, wobei der vorgegebene Zeitraum nur unwesentlich größer ist, als die Laufzeit des die codierte Information tragenden Signals von der Sendeeinheit zur Empfängervorrichtung bei einer maximalen Reichweite der Empfängervorrichtung.

摘要： A transmitter (20) is provided for transmitting a command signal, the transmitter including a rolling code generator (26) operable in response to a control logic (22) to provide a code forming at least part of said transmitted signal. The code is automatically changeable at intervals. A receiver (30) is provided which receives the transmitted signal for operating the lock (37). The receiver also includes a rolling code generator (34) operable in response to a control logic (35) to provide a code associated with or related to the transmitted code to facilitate operation of the security device (37). The code in the receiver (30) is also automatically changeable at intervals substantially in synchronism with the timing of code changes in the transmitter (20). The receiver is arranged to operate the security device even if the codes in the transmitter and receiver are up to a certain number of steps out of synchronism, that number increasing with time.
