  • Patent number: 7154574
    Abstract: A color liquid crystal display device has an array of display pixels (10) for modulating input light and an array of associated color filter elements (40) which comprise electro-optic filtering elements switchable electrically between a color filtering state in which a required color output is produced and a state in which they are substantially transparent to the input light. Such switching can be used beneficially, for example to reduce power consumption by sacrificing full color output and allowing the brightness level of a back light to be decreased in view of the increased optical efficiency of the pixels when the filter elements are in their transparent state, or to improve viewability in the case of a reflective display used in poor ambient lighting.

  • Patent number: 6943854
    Abstract: Rotate-and-pull mechanisms for fiber optic modules. The rotate-and-pull mechanisms have a lever-actuator to unlatch and withdraw a fiber optic module from a cage assembly or a module receptacle. The lever-actuator pivotally couples to the fiber optic module so that when lever-actuator is rotated about its pivot point, the lever-actuator causes the second actuator to release the fiber optic module from the cage assembly. The lever-actuator includes an actuating-tab to cause the second actuator to move when the lever-actuator is rotated. By pulling the lever-actuator away from the cage assembly, the fiber optic module is withdrawn from the cage assembly. A belly-to-belly mounting configuration is introduced for the rotate-and-pull release fiber optic modules.
