Multiple-stage integrating accelerometer
An accelerometer assembly is described for use in activating a switch or the like responding to multiple acceleration pulses in series, comprising: a housing forming a chamber having a first and second end; a mass slidably disposed in the chamber and movable during acceleration from the first end toward the second end; means for biasing the movable mass toward a reset position adjacent the first end; means for damping the movement of the mass in the chamber; cam and follower means carried by the movable mass and the housing for relative movement in response to the acceleration, the cam and follower means including means for temporarily blocking the mass movement toward the second end after a first acceleration pulse; the cam and follower means cooperating together to allow continued movement toward the second end and switch activation in response to at least a second separate acceleration pulse in series with the first.
