Publication number: 20070103439Abstract: An optical mouse images as an array of pixels the spatial features of generally any micro textured or micro detailed work surface below the mouse. The photo detector responses are digitized and stored as a frame into memory. Motion produces successive frames of translated patterns of pixel information, which are compared by autocorrelation to ascertain the direction and amount of movement. A hold feature suspends the production of movement signals to the computer, allowing the mouse to be physically relocated on the work surface without disturbing the position on the screen of the pointer. This may be needed if the operator runs out of room to physically move the mouse further, but the screen pointer still needs to go further. The hold feature may be implemented with an actual button, a separate proximity detector or by detecting the presence of a characteristic condition in the digitized data, such as loss of correlation or velocity in excess of a selected limit.Type: ApplicationFiled: December 21, 2006Publication date: May 10, 2007Inventors: Gary Gordon, Derek Knee, Rajeev Badyal, Jason Hartlove

Publication number: 20060139332Abstract: A hand operated pointing device for use with a computer includes a movable housing, a source of non-coherent light illuminating a work surface and circuitry in the movable housing using arrays of data related to light reflected by the illuminated work surface to produce values by processing portions of a first array with portions of a second array. One of the values may be identified to represent movement of the housing relative to the work surface. The light may illuminate surface irregularities at an angle of incidence low enough to produce suitable arrays of data for processing from highlights and shadows of the illuminated surface irregularities. The circuitry may produce additional values by processing another selected portion of the first array with portions of a third array or may select a fourth array for processing with the third array. Predictions may be derived from the values. Signal may be sent to a computer related to movement of the housing.Type: ApplicationFiled: December 23, 2004Publication date: June 29, 2006Inventors: Gary Gordon, Derek Knee, Rajeev Badyal, Jason Hartlove

Publication number: 20060092311Abstract: 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.Type: ApplicationFiled: November 3, 2004Publication date: May 4, 2006Inventors: Jason Hartlove, Guolin Ma
