摘要： 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.

摘要： 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. A convenient place for an actual hold button is along the sides of the mouse near the bottom, where the thumb and the opposing ring finger grip the mouse. The gripping force used to lift the mouse engages the hold function. Hold may incorporate a brief delay upon either the release of the hold button, detection of proper proximity or the return of reasonable digitized values. During that delay any illumination control or AGC servo loops stabilize. A new reference frame is taken prior to the resumption of motion detection.

摘要： Movement of a hand operated pointing device may be tracked by providing a source of non-coherent light in a movable housing for illuminating a work surface and providing circuitry for producing a plurality of two dimensional arrays of data related to light reflected by surface irregularities on the illuminated work surface and for processing a first array with a second array to track movement of the housing relative to the illuminated work surface. Circuitry may be provided for processing the first array with the second array to predict further movement of the housing relative to the illuminated work surface. Circuitry may be provided for selecting a different portion of the first array in accordance with the prediction for processing with a third array to track further movement of the housing. Circuitry may be provided for determining validity of the tracked movement and sending a signal to a computer related to the tracked movement unless the tracked movement is determined not to be valid.

摘要： 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.

摘要： A camera module includes a gradient index lens on a spacer plate attached over an array of pixel sensors and associated micro lenses. The spacer plate and gradient index lens can be formed at the wafer level during the manufacture of multiple camera modules. A process for manufacturing the camera modules thus provides tolerances and yields provided by wafer processing techniques rather than mechanical assembly.

摘要： An image pickup module made of clear polymer includes an imaging surface, a first mirror, and a second mirror. An object is placed on the imaging surface for imaging. Incident light reflects off the imaging surface. The first of the two mirrors directs the reflected light toward the second mirror. The second mirror directs the directed light toward an image sensor. The two mirrors focus the reflected light on the imaging sensor which converts the focused light to electronic signals to be processed by a microcontroller. The use of the mirrors to direct the reflected light (embodying the image information) has the effect of having a relatively long focal length within a relatively short image pickup module design thereby allowing the pickup module to be manufactured having reduced height compared to prior art pickup modules. The reduced height allows for manufacture of smaller, more convenient image pickup devices.

摘要： In an embodiment, a method of tracking movement relative to a surface involves comparing at least some data elements of a first array with at least some of data elements of a second array if it is determined, from an examination of the first array of data elements, that a characteristic condition does not exist in the first array of data elements, wherein the characteristic condition is related to the uniformity of at least a majority of the data elements of the first array.
