Position sensing for moveable mechanical systems and associated methods and apparatus

Abstract: Position sensing of movable elements including but not limited to machine components is disclosed. Motion of a movable element can produce motion of a magnetic field, which can be detected by magnetic sensors. The motion and/or variations of a magnetic field and/or a magnetic flux may be produced by any combination of a motion of the sensors, associated magnets, or associated magnetic material. Magnetic sensors may be capable of measuring either rotary, or linear motion, or both. Such sensors can provide indication of an incremental position change, an absolute position, or both. Absolute position and high-resolution position sensing may be produced for measurement of either linear and/or angular motion. Suitable magnetic sensors include, but are not limited to, Hall effect devices and/or magneto-resistive elements, and may include multi-element magnetic sensors. Suitable signal conditioning and/or control means such as control electronics can be used to receive output signals from the sensors.

Retrodirective array using the heterodyne technique

Abstract: A retrodirective array using a single microwave mixer to accomplish conjugate phase shift in each element is described. Reradiated patterns were measured for a four-element array to substantiate the predicted performance. This array has an advantage over the Van Atta array in that the elements are not restricted to being located on a plane surface. It is more efficient than the previously used method of employing two mixers to provide conjugate phase shift because of the reduction in converison loss and LO (local oscillator) power.

Backlighting method for an automotive trim panel

Abstract: The present invention relates to an apparatus and method of perforating the cover layer or soft skin of an automotive trim panel such as an instrument panel with a laser to allow light to bleed through the perforations. The light source would preferably be a low heat generating or “cool” type source such as an LED. The light source would be attached to a suitable substrate or incorporated in to a flexible printed circuit and coupled to the vehicle electrical system. This method would enable fill switch integration to a trim panel and provide a seamless styling opportunity regarding the electrical controls. This method would help reduce cost and weight, improve quality, and promote new seamless styling theme.
