Title:

ACCELERATION DETECTION DEVICE

Document Type and Number:

WIPO Patent Application WO/2005/052601

Kind Code:

A1

Abstract:

[PROBLEMS] To provide an acceleration detection device capable of independently detecting an acceleration in a direction parallel with a mounting plane and an acceleration in a direction vertical thereto by mounting two acceleration sensors on one mounting plane. [MEANS FOR SOLVING PROBLEMS] These two same acceleration sensors (A) and (B) having the directions of axes of the maximum sensitivities relative to the sensor mounting plane (10) angled by Ѳ relative to the mounting plane (10) are installed in the mounting plane (10) in the state of being inverted by 180&ring each other. The acceleration in the direction vertical to the mounting plane can be provided by using the sum (S_A + S_B) of outputs (S_A) and (S_B) from the two acceleration sensors, and the acceleration in the direction parallel with the mounting plane can be detected by using a difference (S_A - S_B) between the outputs (S_A) and (S_B) independently of the acceleration in the vertical direction.
