A synchronous demodulation circuit (100) uses a digitally controlled track-and-hold circuit (106) to capture the peak amplitude of a rectified signal. A microcontroller (108) controls the track-and-hold circuit (106). In particular, the microcontroller (10...

In order to provide a method and a device for controlling a seatbelt retractor in which a smooth seatbelt retraction for a vehicle occupant is achieved while a waste of power consumption of a battery is prevented in step S11, it is determined whether or no...

A weight-based occupant characterization method reliably distinguishes between large and small adult occupants by dynamically adjusting a threshold used to distinguish between large and small adult occupants. The threshold adjustments effectively increase ...

A seating sensor (11) detects whether a seat (2) is occupied by a person. A microcomputer (12) determines whether the seat (2) is occupied by a person based on the output of the seating sensor (11). If a seating signal indicating that the seat (2) is occup...

The operating method automatically determines the activation condition of safety-critical function units (12,13) within the automobile (1), dependent on the detected occupation of the passenger seats (5,6,7,15). An Independent claim for a safety device for...
