A sensor module for use in a low-cost weight-measurement and sensing system is provided. The sensor module may include a substrate configured to be mounted between a floor pan of a vehicle and a seat of the vehicle. The sensor module may further include a force sensing element disposed upon the substrate. The force sensing element may be configured to sense a force applied thereupon, and generate a reading representative of the force applied thereupon in response thereto to provide a sensor reading. The sensor module may also include a wiring harness connected to the force sensing element. The wiring harness may be configured to transmit the sensor reading to a control module. The substrate may define an aperture configured to surround a fastening element used to fasten the seat to the floor pan of the vehicle.

The present invention provides a method and device for simulating impact conditions which has a test sled , simulated occupant ( ), and a pre-impact force-generating device. The pre-impact force-generating device can apply force directly to the simulated occupant being ( ), thereby overcoming many of the cost problems associated with applying a low and long duration force directly to a test sled ( ). The pre-impact force-generating device can be designed such that instead of providing a low and long duration force to a simulated occupant ( ), it provides a short and high impact force to the simulated occupant ( ). An impact force-generating device provides impact force directly to the sled ( ) which simulates impact conditions.

The present invention is a power supply for a fluorescent light, particularly a sub-miniature fluorescent light (SFL) which provides compensation for temperature and age effects of the fluorescent light. One or more SFLs are powered by a variable output anode controller and a variable output cathode controller, wherein the illumination output of the SFLs is selectively adjustable based upon the voltage output of one or both of the anode and cathode controllers. In a first example of implementation of the invention, an illumination feedback circuit is provided to the anode/cathode controller, wherein the voltage output is adjusted to compensate for diminished illumination, caused for example by cold operating conditions or age of the sensed SFLs. In a second form of the present invention, a temperature feedback circuit is provided to the anode/cathode controller to provide the aforesaid voltage adjustment to compensate for diminished illumination. In another aspect of the present invention, the SFLs are placed into a ready-state for being presently illuminated based upon sensing of a wake-up signal.

A method for sensing the occurrence of a vehicle crash is provided for a vehicle having an occupant restraint system operatively connected with a crash sensor having an accelerometer, which produces an accelerometer signal, and with an occupant position sensor which produces a position signal. The crash sensor includes an adjustable filter. The method includes the steps of: a) calculating an estimated occupant displacement by integrating the accelerometer signal twice; b) comparing the estimated occupant displacement to the position signal; and c) adjusting the adjustable filter based upon the comparing step to optimize control of the occupant restraint system. In this manner, actual body position of the occupant may be more accurately predicted and measured, which allows optimization of air bag deployment.
