Integrating accelerometer capable of sensing off-axis inputs |
摘要 |
An accelerometer (10) features a housing (12) having an passage (14) of rectangular cross-section formed therein, the width dimension of which gradually increases with increasing displacement along a central longitudinal axis (16) away from a first end (24) of the passage; and a puck-shaped magnetic sensing mass (26) located within the passage whose magnetic axis extends in a direction normal to the basal surface (18) of the passage. A pair of magnetically-permeable elements (22) on the housing magnetically-interact with the sensing mass so as to bias the sensing mass towards a first position within the passage; and a first and second pair of stationary beam contacts (30) project into the passage so as to be bridged by respective electrically-conductive circumferential surfaces (28) on the sensing mass when it moves to a second position within the passage. A pair of electrically-conductive nonmagnetic plates (32) on the housing magnetically interact with the sensing mass to damp the movement thereof within the passage. A pair of horizontally-wound coils (36,38) provide both test and reconfiguration functions.
