    摘要: An accelerometer for measuring the displacement of a magnet body using magnetic detecting elements is provided, the accelerometer having superior measurement accuracy by suppressing influence of a peripheral magnetic field. The accelerometer has detecting units each having a cantilever which is elastically deformed so as to rotate around a fixed end thereof, a magnet body provided at a free end of the cantilever, and a magnetic detecting head portion disposed outside the rotation region of the cantilever. In order to correct detection signals output from the magnetic detecting head portions, the accelerometer has peripheral magnetic field detecting portions for measuring a peripheral magnetic field acting on the magnetic detecting head portions and the magnet bodies.

    摘要: An electronic compass and direction finding method includes a geomagnetic direction sensor having two sensor elements for detecting perpendicular components of the Earth's magnetic field vector. A microcomputer is coupled to the geomagnetic direction sensor to compute a heading of a vehicle in software. Even if the electronic compass displays directional errors due to magnetization of the vehicle, a center of an azimuth circle can be immediately corrected by a center calculating means and a relatively accurate heading can be displayed. Later, the center of the azimuth circle can be corrected with a higher accuracy by a least squares calculating means. This frees a vehicle driver from uneasiness due to display of an intelligible direction.

    摘要: A motion sensor which can easily and accurately detect bearing, attitude and acceleration in any of three-dimensional directions and a portable telephone using the same. The motion sensor comprises three magnetic sensing parts for detecting magnetic field strength in 3-axis directions orthogonal to one another, and three acceleration sensing parts for detecting accelerations in the 3-axis directions. Each of the acceleration sensing parts has a magnet body constituted to be able to displace depending on acceleration, and a magnet displacement detection head for detecting a displacement of the magnet body. The three magnetic sensing parts and the three magnet displacement detection heads are all made of the same type of magnetic detection elements which operate based on common operation principles. The three magnetic sensing parts and the three acceleration sensing parts are integrated into one modular package together with one electronic circuit for controlling these six magnetic detection elements.
