Two dimensional acceleration sensor
The Journal of the Acoustical Society of America, 1991An acceleration sensor for detecting an acceleration in a plane, and having a housing, and a disk magnet arranged in a magnetic fludi stored in the housing. The movement of disk magnet is limited, i.e., a translational movement or rotational movement thereof can occur only in the plane, by projections formed in the housing, between which projections ...

Acceleration and deceleration sensor
The Journal of the Acoustical Society of America, 1987An acceleration and deceleration sensor for use with safety devices in motor vehicles includes a reed switch and a movably mounted permanent magnet system which closes the switch during a collision. The permanent magnet system is provided by a pair of magnets having like poles which face each other, so that the magnets repel each other.

An acceleration limit sensor presenting a support device (14; 36), a seismic mass (10; 32) and a connecting device (12; 34) with which the seismic mass (10; 32) is mounted on the support device (14; 36). The connecting device (12; 34) presents a predetermined breaking point, which interrupts the connection between seismic mass (10; 32) and the support ...

Semiconductor acceleration sensor including off axis acceleration cancellation
The Journal of the Acoustical Society of America, 1994A semiconductor acceleration sensor has an acceleration sensor element on which gauge resistors are arranged so as to cancel sensed output component corresponding to any acceleration acting in a direction different from an acceleration to be sensed. Consequently, acceleration can be precisely sensed without being influenced by acceleration acting in ...

Acceleration sensor and measurement method
The Journal of the Acoustical Society of America, 1997An acceleration sensor has a seismic mass having movable electrodes. The movable electrodes are designed as differential capacitors between two fixed electrodes. Also provided are additional electrodes which are arranged opposite movable electrodes or opposite bending elements on which the seismic mass is suspended.
