    Abstract: An apparatus and method for generating a lamina of light. The apparatus includes an optically transparent member having an input configured to receive light and one or more facets formed in the optically transparent member. As light enters and travels through the member, a lamina of light is created by the light reflecting off the facets. In one application, the lamina of light is provided in the free space adjacent a touch screen display. When the lamina is interrupted during a data entry operation to the screen, an optical position detection device is used to determine the data input based on the location of the interrupt in the lamina. In various other embodiments, the position and uniformity of the lamina may be controlled by selecting the angle, depth and tilt of a reflective surface of the facets in the optically transparent member.

    Abstract: A system and method for auto-focusing light. The system includes at least one focusing lens operable to direct light toward a focal point. The system further includes a sensor array disposed adjacent to the lens assembly such that the light through the lens assembly is directed to the sensor array near the focal point and a bubble array having a plurality of bubble generators. The bubble array supports the sensor array and the bubble generators are operable to maneuver the supported sensor array with respect to the focal point. Such a light focusing system is able to provide an auto-focus capability to a camera system that does not have a large amount of space available for a motor-driven auto-focus system. Furthermore, the bubble array is power efficient and does not require the amount of energy to operate as is required for a motor-driven auto-focus system.

    Abstract: An optical conduit in an optical mouse is used to channel light from a light source onto a surface for illumination. Light from the light source is totally and internally reflected within the optical conduit towards the surface. To improve the efficiency of light transmission, the light source is glued to the exterior of the optical conduit, or embedded within the optical conduit itself. A reflector cup can be used to surround the light source so as to redirect light from the light source towards the output end of the optical conduit. The optical conduit can have curved surfaces that fit parabolic or hyperbolic equations, or other equations of second-order or higher.

    Abstract: An image sensing device is disclosed having a die formed with an array of photosensing sites and a structure of optical material having infrared absorbing characteristics formed over the photosensing sites. An embodiment is disclosed in which the structure of optical material having infrared absorbing characteristics is formed as an array of microlenses for directing visible image light onto the photosensing sites and at the same time filtering out infrared wavelengths that interfere with image capture. Alternatively, the structure may be designed to filter out other ranges of wavelengths outside of the visible spectrum.
