摘要： Pixels in an array of image sensor pixels contain photo-sensors and circuits having inputs connected to the photosensors. The circuits have feedback loops for reducing fixed pattern noise in the array. Output from each pixel is used to latch a multibit counter value supplied by a global counter. Each feedback loop preferably includes a pair of alternately-toggling switching transistors to minimize unwanted charge injection. An image sensor according to the invention can be used for, e.g., motion sensing.

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： Edge-sensitive, state-based single flux quantum (SFQ) based circuitry and related methods convert return-to-zero (RZ) or non-return-to-zero (NRZ) encoded SFQ-pulse-based signals to bilevel NRZ phase signals that can subsequently be converted to bilevel voltage signals by an output amplifier (OA). The SFQ-based circuitry can be integrated with a current amplification stage of a driver that can be coupled to a stage of the OA. The SFQ-based circuitry can be made to be compatible with RQL-encoded input signals that can be either RZ or NRZ. The SFQ-based circuitry can thus be compatible with both wave-pipelined (WPL) and phase-mode (PML) RQL circuitry. Because the SFQ-based circuitry and related methods are edge-sensitive and state-based, they can function at system clock rates in excess of 1 GHz with reduced glitches and improved bit error rates as compared to other superconducting RZ-NRZ conversion circuitry and methods.

摘要： The technology provides various embodiments for controlling brightness of a see-through, near-eye mixed display device based on light intensity of what the user is gazing at. The opacity of the display can be altered, such that external light is reduced if the wearer is looking at a bright object. The wearer's pupil size may be determined and used to adjust the brightness used to display images, as well as the opacity of the display. A suitable balance between opacity and brightness used to display images may be determined that allows real and virtual objects to be seen clearly, while not causing damage or discomfort to the wearer's eyes.

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： Circuitry is employed to provide an array of photoelements for generating an electrical signal from light energy. The circuit is essentially comprised of a plurality of photoelements including a light-receiving portion, which may include a phototransistor for receiving light and generating electrical energy therefrom, and a non-light-receiving portion, which may include amplification circuitry for properly biasing the phototransistor base and for amplifying the light signal. Within the array, geometric centers of vertically and horizontally adjacent phototransistors are equidistant from one another to form a symmetrical array of photoelements. A relatively high fill factor is achieved by an efficient, symmetrical layout of the photoelements within the array. One main advantage of the high fill factor of the symmetrical array is that it generates a greater light signal than related designs, which eliminates the need for optical magnification of pixels on an original sheet of paper. Additionally, the advantage of the symmetrical array is that the subsequent signal processing of the image captured by the photoreceiving array is not required to correct for unequal distances between geometric centers of adjacent phototransistors.

摘要： A scanning mouse has two optical navigation sensors to allow measurement of both translation and rotation of the scanning mouse. It also has an image sensor, and the ability to digitize the sensed image data. There may be a second image sensor at perpendicular to the first. A high speed digital data path connects the scanning mouse to the computer. Software in the computer processes image line data that includes the locations of the navigation sensors and the digitized image data to produce partial scanned images that are further assembled into a complete image within the environment of the computer. Each optical navigation sensor 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.
