Patent ID: 7266988

Claim:
A micro-electromechanical shock sensor device, comprising: a moveable proof mass comprising a first mechanical latch and a first electrical contact; and a pawl comprising a second mechanical latch, the second mechanical latch disposed at a latching distance from the first mechanical latch, the latching distance corresponding to a latching threshold shock level; and a second electrical contact disposed at an electrical contact distance from the first electrical contact, the electrical contact distance corresponding to an electrical contact threshold shock level; wherein the first mechanical latch moves toward the second mechanical latch and the first electrical contact moves toward the second electrical contact when the proof mass experiences a shock level in the direction of the latching threshold shock level; and wherein the first mechanical latch engages with the second mechanical latch when the shock level reaches the latching threshold shock level; and wherein the first electrical contact contacts with the second electrical contact when the shock level reaches the electrical contact threshold shock level.
