  • Combined optical light pipe and protective enclosure
    Patent number: 6752526
    Abstract: A light pipe, including a transparent housing member characterized by a first refractive index, a light source positioned to shine a light beam through the transparent housing member, and at least one enclosed pocket positioned within the transparent member. The enclosed pocket is characterized by a second refractive index, wherein the first refractive index is substantially greater than the second refractive index. Light shining through the transparent member is totally internally reflected by the enclosed pocket.
    Type: Grant

  • Apparatus and method of determining position by means of a flexible resistive circuit
    Publication number: 20030001748
    Abstract: A method of determining the location of a movable seat in a vehicle relative a stationary reference point therein. The method includes the steps of providing a flexible member characterized by electrical resistance as a function of curvature, operationally connecting the flexible member to the seat such that movement of the seat relative the reference point bends the flexible member, moving the seat relative the reference point, measuring the electrical resistance of the flexible member, and determining the location of the seat.
