Abstract: Apparatus and methods for automating the outside rearview mirror orientation of a vehicle having at least one rearview mirror. The apparatus comprises a light directing device which emits a visible light ray, orientation detectors, an electronic controller, and a mirror positioning apparatus. The light directing device comprises a pivotal tube containing a light source. The orientation detectors detect the orientation of the light ray. In one embodiment, the apparatus also comprises a distance sensor which senses the distance between the light directing device and the driver's eyes. Once the driver has manually adjusted the light directing device so as to see the light source, the driver operates a switch, which activates both the distance sensor and the orientation detector. The controller includes a microcomputer programmed to determine the desired orientation of the outside mirror and generate control signals.

Abstract: Apparatus for determining the location and other body parameters of a seat occupant prior to deployment of an automobile airbag comprises a vector sensing device, and an electronic controller operatively coupled to the vector sensing device. The vector sensing device senses the vector extending between a fixed point of reference on an automobile and a seat occupant's eyes after the occupant assumes a sitting position. The electronic controller first determines a current location for the occupant's eyes based upon the vector signals, and the determines inflation parameters based upon the current location, anthropometric data, and a dynamic body model.

Abstract: Apparatus for determining the location of the eyes of a driver for a vehicle having a central inside rearview mirror, comprises a distance sensor, an orientation detector, a signal processor. The distance sensor senses the distance between the central mirror and the driver's head. The orientation detector detects the orientation of the inside mirror. Once the driver has manually adjusted the inside mirror, the driver operates a switch, which activates both the distance sensor and the orientation detector. The signal processor, preferably a microcomputer, uses the equation of a parabola in space to determine the location of the parabola's focus, and thereby determine the location of the driver's eyes.
