Micro sensor for detecting and calculating e.g. shocks, has passive shock calculating unit associated to displacement unit, and inertial mass and passive unit`s toothed wheel concentrically disposed to engage tooth with toothed wheel

摘要

The sensor has a unit (2) displaced relative to a support (1) in an elastic manner and including two arms (4, 5) whose ends are integrated to the support and a ring-shaped inertial mass (6). The mass is integrated to a rectilinear arm (7) whose free end has a tooth (10) having a triangular shaped free end. A passive unit calculating the shock is associated to the unit (2) and has a toothed wheel (13) free in rotation around an axle (14). The inertial mass and the toothed wheel are disposed in a concentric manner, so that the tooth (10) integrated to the arm (7) engages with the toothed wheel. An independent claim is also included for a machine including a micro sensor.
