  • Patent number: 8395843
    Abstract: An array of light valves switch light by enabling and disabling total internal reflection (TIR) on a surface of the light valve. The disabling of the TIR is accomplished by putting another optical element in contact with the surface and then diffusing or changing the direction of the light. The mechanical mechanism to move the optical element is a simple one in that it only moves the optical element a small distance to change the valve from a first position to a second position.

  • Patent number: 8366302
    Abstract: An optical system is disclosed that uses an LED light source. The light output is coupled to an optic element formed from a material with a high refractive index. The coupling of the light to the high index material significantly reduces the cone angle of the light. The system is very efficient in that nearly all the light generated by the LED is directed to the intended subject.

  • Patent number: 8297818
    Abstract: An optical system utilizing a light pipe in which light travels by total internal reflection (TIR) accurately controls the light exiting the pipe. The system achieves accurate control of the reflected light by selectively extracting light from a limited area of the light pipe. The configuration of the reflectors used for the selective extraction of the light determines the nature of the output light. The reflectors are preferably located on an output side of the light pipe. All light output by the system is directed by the reflectors.

  • Patent number: 8272770
    Abstract: A flat panel display uses pixels that are turned on or off by the enabling or disabling total internal reflection, TIR, of a light guide. A reflective surface directs the switched light towards the viewer. An optional mask can be employed to provide extremely high contrast ratios in low and in high ambient lighting conditions. The elements that enable TIR can be enabled quickly because of their small size and weight, resulting in a very fast switching speed. The fast switching speed allows colors to be generated and displayed in a sequential manner.

  • Publication number: 20120127694
    Abstract: An optical system with an LED light source utilizes a base with an inverted conical shape to conduct light to a phosphor layer. The phosphor layer emits light from both upper and lower surfaces. The base and a substantially mirror image cap element facilitate efficient extraction of the phosphor-generated light from the optical system so that the output of the system is omni-directional light suitable for common lighting applications. The system is very efficient in that nearly all the light generated by the LED is transmitted to the phosphor layer, and nearly all the light emitted from the phosphor layer is output from the system.

  • Patent number: 8152352
    Abstract: A light guide with optics accurately controls the light exiting the guide. The device achieves accurate control of the reflected light by extracting light from a limited area of the light guide. The configuration of the reflectors used for the selective extraction determines the nature of the output light. The reflectors are preferably located on a side of the light guide opposite to an output side of the light guide.

  • Patent number: 8104949
    Abstract: A time indicator device comprised of first and second interconnected reservoirs containing first and second liquids respectively. A first barrier is provided between said first and second liquids to prevent said liquids mixing. Said first barrier is connected via a conduit to a third reservoir containing a third liquid which is adapted to pass along said conduit over a first predetermined time period and to effect removal of said first barrier upon contact to facilitate mixing of said first and second liquid and generation of a liquid mixture within the second reservoir of different color to the second liquid prior to mixing and thereby provide an indication of when said first predetermined time period has elapsed.

  • Patent number: 7519479
    Abstract: A process and apparatus for sensing gas concentration in a gas stream involves producing a succession of difference values representing differences between successive sample values of a succession of sample values representing instantaneous reflectance of light from a compound produced by reacting a reagent with the gas being sensed and producing a gas concentration value in response to a maximum difference value of the succession of difference values.
