    Abstract: A probe for use in a coordinate digitizing system includes an indicator, such as a pointing tip or crosshairs, and a marker, the location of which can be determined by a marker tracking system relative to a coordinate system. The probe is configured to effectively place the marker's virtual image—as seen by the tracker—at the same location as the indicator without blocking a user's view of the indicator.

  • Patent number: 8164045
    Abstract: An optical system and method for controlling light propagation along a light path. An optical element such as a lens is formed of a first light transmitting material and has a surface finish effective to scatter light impinging on the surface. Index matching material contacts to a portion of the surface so as to reduce or nullify the scattering effects of the surface finish within the portion. This allows the first optical element to have surfaces that have been generally prepared for scattering light and then later selectively negate the scattering effects of the surface finish by contacting portions of the surface with index matching material. As such, light in the optical element directed toward a surface or boundary within selected portion propagates into or out of the optical element. Light outside of the selected portion is scattered. Such an arrangement helps to reduce image degradation due to light outside of the light path being reflected about within the optical system.

  • Patent number: 7965884
    Abstract: An exemplary method and system for testing light-emitting diodes (LEDs) uses a camera module to take two bulb images of transparent bulbs connected to each of the LEDs. A first bulb image is captured when the LEDs are set in a power-on state, and a second bulb image is captured when the LEDs are set in a power-off state. The method divides each of the two bulb images into small pictures, and calculates an average pixel value of each of the small pictures. After calculating a first difference of each of the small pictures between the average pixel value and a first predetermined value, and a second difference of each of the small pictures between the average pixel value and a second predetermined value, the method ascertains a present state of each of the LEDs by comparing the two differences.
