Abstract: A pressure measuring method, applied to a pressure measuring apparatus, comprising: measuring a first pressure sensing value of the pressure measuring apparatus, which corresponds to a first pressure in a test mode; measuring a second pressure sensing value of the pressure measuring apparatus, which corresponds to a second pressure in the test mode; generating a first corresponding function according to the first pressure, the second pressure, the first pressure sensing value and the second pressure sensing value; sensing a third pressure sensing value via the pressure measuring apparatus in a normal mode; and generating a third pressure according to the third pressure sensing value via the first corresponding function; wherein the pressure measuring apparatus operates at a first scan frequency. By this way, the pressure sensing value can be calibrated, to solve the issue that the pressure sensing values are affected by scan frequencies.

Abstract: A multiple detection system is applied to a vehicle and includes a contact-type detection module adapted to generate a contact-type detection datum, a contactless-type detection module adapted to generate a contactless-type detection datum, and an operation processor electrically connected with the contact-type detection module and the contactless-type detection module in a wire manner or in a wireless manner. The operation processor sets at least one of the contact-type detection datum and the contactless-type detection datum according to an environmental status of the vehicle to be a main detection result of the multiple detection system, and further sets the other detection datum to be an auxiliary detection result of the multiple detection system, for acquiring a passenger feature inside the vehicle.

Abstract: A pressure measuring method, applied to a pressure measuring apparatus, comprising: measuring a first pressure sensing value when the pressure measuring apparatus operates at a first scan frequency and receives a first pressure; and measuring a second pressure sensing value when the pressure measuring apparatus operates a second scan frequency and receives the first pressure. The first pressure sensing value and the second pressure sensing value are different, and a change between the first pressure sensing value and the second pressure sensing value is according to a change between the first scan frequency and the second scan frequency. The first scan frequency and the second scan frequency are different. The pressure measuring method can further comprise a calibrating mechanism to compensate the sensed pressure. By this way, the pressure sensing value can be calibrated, to solve the issue that the pressure sensing values are affected by scan frequencies.
