| A shock sensor comprises a substrate and at least one flexure coupled to the substrate and configured to deflect upon an application of force to the shock sensor sufficient to deflect the flexure. Deflection of the at least one flexure produces a detectable change in an electrical property of the shock sensor. Examples of detectable changes in an electrical property of the shock sensor include an open circuit condition, a closed circuit condition, and a variation in voltage of a piezo-electric detector. In some embodiments, the change in the electrical property of the shock sensor may be remotely read by interrogation of a radio frequency identification transponder positioned on the substrate using a remote radio frequency identification transceiver. The disclosure also relates to a shock sensing system and method of shock detection. | ||||||

| 87 | Method and apparatus for sensing a rollover | US12028956 | 2008-02-11 | US20080147280A1 | 2008-06-19 | David S. Breed |
| Vehicle with an occupant safety system for use in a crash involving the vehicle includes an occupant protection device, an inertial measurement unit (IMU) arranged to measure acceleration of the vehicle in three orthogonal directions and angular velocity of the vehicle about three orthogonal axes, the accelerations and angular velocities being measured at a substantially common location, and a processor coupled to the IMU for receiving the measured acceleration of the vehicle and the measured angular velocity of the vehicle. The processor determines whether the vehicle is experiencing a crash, and specifically, a rollover, and if so determines whether actuation of the occupant protection device is beneficial. If actuation is deemed beneficial, the processor generate a signal to actuation of the occupant protection device. The occupant protection device may be an inflatable airbag. | ||||||

| A vehicle crush detecting device consists of an electrically conducting tube with an electrically conducting rod concentrically positioned within the tube along with insulating means positioned at at least two points between the rod and the tube to insulate the rod from the tube. The electrically conducting tube is deformed during a vehicle crash by a force greater than a predetermined magnitude which causes the tube to contact the rod in response to the crush of a vehicle of a predetermined amount. The crush sensor is mounted in the crush zone of the vehicle and is used in conjunction with automobile passive restraint systems such as airbags. | ||||||

| A crash sensor, designed for arrangement in the crush zone of a motor vehicle, is operative to determine when and if a crash is severe enough to deploy the passive restraint system (e.g. airbag or seat belt tensioner) of the vehicle. The sensor is responsive to trigger the passive restraint system when the vehicle impact with a barrier causes vehicle elements in the crush zone to deform as far back as the sensor position. | ||||||
| 96 | Pendulum-type inertia sensor switch | US32906273 | 1973-02-02 | US3835273A | 1974-09-10 | STOLARIK E |
| A multi-directional crash sensor for triggering air bag safety devices on a vehicle, having different response thresholds to accelerations from different directions. A pendulum having one electrical contact is pivoted within a housing for motion in any direction in response to acceleration. A second contact is positioned around the pendulum and is configured so that the angular displacement from the pendulum''s nominal position to the second contact is different for different directions of motion of the pendulum. A non-conductive membrane having a predetermined puncture resistance may be placed over the contact and the pendulum may be provided with sharp protrusions for piercing the membrane to make electrical contact only when accelerations of predetermined magnitude occur.

| 97 | Impact responsive switch with frangible element holding contact plunger in unactivated position | US3794794D | 1972-11-10 | US3794794A | 1974-02-26 | PROVANCHER R |
| The impact switch is responsive to the movement of a vehicle member subjected to an impact force as the result of a vehicle collision with a fixed object or another vehicle. The switch comprises a plunger device movable longitudinally within the cylindrical housing containing axially spaced electrically conductive contact rings. The plunger device carries an electrically conductive contact means engagable with the contact rings in sequence as the plunger device is driven into the housing. A shear pin normally holds the plunger device against displacement such as could be caused by vibration or longitudinally exerted inertial forces. Upon a predetermined impact force being applied to the plunger device, the shear pin is adapted to shear and permit displacement of the plunger means. Engagement of the plunger contact means with the contact rings closes an electrical circuit through the switch. The closed electrical circuit may be used to trigger an airbag system or other vehicle passenger restraint device.
