  • Patent number: 5012274
    Abstract: An active matrix LCD light valve between crossed polarizers, utilizing individual transistors to control each "pixel area" of the LCD and storage elements to store signal data for each pixel, with optically shielded "dead spaces" between pixels to eliminate electric field crosstalk and non-information-bearing light bleed through, is illuminated with a bright independent light source which creates a video image projected via specialized projection optics onto an internal or external screen without distortions, regardless of the angle of projection onto the screen. Use of heat sinks, IR reflective coatings, heat absorbing optics, optional fluid, and a thermistor controlled pixel transistor bias voltage injection servo circuit stabilizes image performance, maintaining accurate color and contrast levels as the LCD changes temperature.

  • Patent number: 4999068
    Abstract: An anatomical multilayer seat for use on a bicycle or the like. The seat comprises a formed substantially rigid shell covered by a flexible cover sheet and having a layer of soft encapsulated gel material provided between the cover shell and the seat shell. The encapsulated gel layer is constrained against any appreciable lateral movement while permitting only limited deflection of the gel during use by a lower formed foam layer provided between the shell and the cover sheet to produce a controlled graduated support for the rider. If desired, a second upper layer of a resilient material can be advantageously provided between the gel layer and the cover sheet of the seat for encapsulating the gel layer. The invention also includes a method for making the anatomical multilayer seat.
