摘要： A security system for actuating a security mechanism of a vehicle includes a transceiver coupled to the security mechanism and having one transmission channel for transmitting a first signal and a number of reception channels. A remote radio-frequency transponder key has a number of transmission channels (320, 322, 324; 330, 332, 334) and one reception channel matched to the respective reception and transmission channels of the transceiver. The transponder key is arranged to transmit an unlock signal to the transceiver upon reception of the first signal. The unlock signal is verified by the transceiver as valid before actuating the security mechanism. The transceiver is further arranged to select a channel for reception of the unlock signal and to embed the identity of the selected channel in the first signal (210), such that the transponder key transmits the unlock signal using the selected channel.

摘要： A first input voltage is applied to the input of a sensor (110), and a first output voltage is measured at the output (161). A second input voltage is then applied to the input of the sensor (110) , and a second output voltage is measured. Then the first and the second output voltages are compared to determine whether a predetermined relationship exists between them.
