The present invention provides a technical solution eliminating the possibility of falsifying the airbag history in a vehicle. When purchasing the used vehicle, the implementation of this solution makes it easy to check whether the vehicle is equipped with a specific airbag or the airbag is original, i.e., it is installed by a manufacturer, or if the airbag is replaced, whether it was replaced by an authorized service. A tag is attached to the airbag in such a way that if the airbag deploys, the tag will be damaged and cannot function. The tag is an electronic device that stores the unique identification data in its memory that can be read by a dedicated reader. If the tag is undamaged and the reader can retrieve the identification data, then the read data is checked with the data for linking the identification data to the vehicle in the database.

In a method for protecting vehicle occupants in the passenger compartment of a vehicle, particularly a motor vehicle. It is provided as essential to the invention that at least one structure-borne sound signal is captured by at least one structure-borne sound sensor, the captured structure-borne sound signal is evaluated by at least one evaluation device, the structure-borne sound signal can be produced by at least one person located in the passenger compartment of the vehicle, and after the capture and evaluation of the structure-borne sound signal at least one control signal is sent to a triggering device of an air supply device to introduce air into the passenger compartment of the vehicle.

A safety device has a lower portion and an upper portion. The lower portion defines a cavity for receiving a seat belt buckle assembly and has at least one rear wall portion extending between opposing sidewalls that partially define the cavity. The rear wall portion forms a slot area to permit a strap attached to the seat belt buckle assembly to extend from the cavity when the seat belt buckle assembly is positioned in the cavity. The rear wall portion is configured to prevent the seat belt buckle assembly from moving laterally out of the cavity. The upper portion is hingedly coupled to the lower portion such that the upper portion completely covers the cavity of the lower portion when the upper portion is rotated into engagement with the lower portion.

A system for detecting a mismatch between first and second input signals includes first and second analog-to-digital converters, a time-division multiplexing circuit, first and second processors, a time-division de-multiplexing circuit, and a gating circuit. The first processor includes a first sinc filter, a first trimmer, a first infinite impulse response (IIR) filter, and a first high pass filter (HPF). The second processor includes a second sinc filter, a second IIR filter, and a second HPF. A bandwidth of the second IIR filter and the second HPF is greater than a bandwidth of the first IIR filter and the first HPF. A transfer function of the first IIR filter and the first HPF uses floating-point coefficients and a transfer function of the second IIR filter and the second HPF uses coefficients that are an integral power of two.

A safety device for preventing accidental discharge of an airbag. A lower portion of the safety device includes two opposing sidewalls at least partially defining a cavity for holding a seat belt buckle assembly. An upper portion of the safety devices is hingedly coupled to the lower portion. The safety device also includes a mechanism for securely latching the upper portion to the lower portion and a mechanism for releasing the upper portion from the lower portion when the upper portion is securely latched to the lower portion to allow the upper portion to rotate away from the lower portion.
