    摘要: In a process for capacitive object detection in a vehicle seat, capacitors arranged in the backrest and in the seat surface are influenced by an object. The capacitors are acted upon by alternating voltage and their capacitance is determined individually. From the value of each of the two capacitances, an evaluation of the object is derived by means of a value table. When the two evaluations correspond to one another (concerning the type of an object), an occupant protection system assigned to the seat is correspondingly activated or deactivated.

    摘要: In a process for capacitive object detection in a vehicle seat, capacitors arranged in the backrest and in the seat surface are influenced by an object. The capacitors are acted upon by alternating voltage, and the time variation of their capacitances is determined individually. From the values of each of the two capacitances, an evaluation of the object is derived by means of a value table and, when the two evaluations correspond to one another concerning the type of an object, an occupant protection system assigned to the seat is correspondingly activated.

    摘要: A method and apparatus for monitoring the interior space of a motor vehicle by means of IR radiation include at least one stationary IR transmitter and at least one stationary IR receiver arranged in a central position in the vehicle interior space. The interior space is at least temporarily irradiated. The reflected IR radiation is received by an IR camera as IR receiver. For suppression of interfering effects two images of the same object are recorded at different illumination levels. The two images are subtracted from one another with respect to their gray scale values.
