Patent ID: 7446645

Claim:
Arrangement for actuating electrical or electromechanical devices ( 10 ) on or in a vehicle, with at least one sensor ( 40 ), which responds to approach or contact; with a memory for nominal data and with a controller, which compares the incoming actual data with the nominal data and, if the comparison is successful, releases the actuation ( 23 ) of the device ( 10 ), wherein during a setup phase of the arrangement, at least one data set (G 1 , B 1 , B 2 ) of the signals (G 1.1 -G 1.16 , B 1.1 -B 1.16 , B 2.1 -B 2.16 ) obtained over the course of time during the response of the sensor ( 40 ) is recorded at a minimum of several defined times (t 1 -t 16 ) and stored in memory, namely, a set (G 1 ) of good data (G 1.1 -G 1.16 ) typical of actuation and/or a set (B 1 ; B 2 ) of bad data (B 1.1 -B 1.16 ; B 2.1 -B 2.16 ) typical of errors; in that during the later duty phase of the arrangement, a responding sensor ( 40 ) records an actual data set of analogous signals over the course of time at the same defined times (t 1 -t 16 ) as those used during the setup phase; in that this actual data set is compared by the controller with at least one of the stored data sets (G 1 , B 1 , B 2 ); and in that the controller releases ( 44 ) the actuation of the device only if the actual data set agrees with the good data set (G 1 ) and/or is not the content of a bad data set (B 1 ; B 2 ).
