Patent ID: 7231804

Claim:
A multiple shock event sensing device, comprising: a substrate; shock sensors coupled to said substrate and arranged in an array defined by a plurality of rows and at least one column, each of said shock sensors having a moveable portion and a restraining portion mechanically coupled to said moveable portion and fixed to said substrate for fixing a position of said moveable portion; and a moveable bar coupled to said substrate and positioned between adjacent rows from said plurality of rows wherein each of said adjacent rows is defined by a first row and a second row, said moveable bar having a contact portion positioned adjacent said moveable portion of each of said shock sensors in said first row, said moveable bar further having a locking portion mechanically coupled to said moveable portion of each of said shock sensors in said second row for preventing movement thereof while superseding functioning of said restraining portion of each of said shock sensors in said second row, wherein any said restraining portion in said first row failing as a result of a shock event allows a corresponding said moveable portion to experience movement and engage said contact portion of said moveable bar to cause a corresponding movement of said moveable bar that mechanically uncouples each said locking portion of said moveable bar from said moveable portion of each of said shock sensors in said second row, wherein said shock sensors in said second row assume a role equivalent to that of said shock sensors in said first row prior to occurrence of said shock event.
