    摘要： A system, method, and method of manufacturing directed to an optical device with increased accuracy in tracking ability. The increased accuracy can be achieved by using a multiple sensor system. A second sensor is added to the optical device. The second sensor increases the probability of obtaining a high quality image. Thus, the tracking ability of the device can be performed with greater accuracy over a single sensor device. The second sensor can also perform additional functions.

    摘要： An optical detection system and method detects movement of an optical pointing device in a data processing environment. The system works with any surface than can diffusely scatter a collimated beam from a coherent light source. Specifically, the system comprises a coherent light source and an optical sensing assembly. The optical sensing assembly comprises a plurality of photosensor arrays and a plurality of optical elements. Each photosensor array includes pixels of a particular size and shape. Each optical element has an artificially limited aperture and is associated, through optical matching, with a respective photosensor array. The coherent light source generates a collimated beam that is diffusely reflected off of the surface. The optical sensing assembly receives the diffusely reflected, or scattered, collimated beam and passes it through the artificially limited apertures of the optical elements to the associated corresponding photosensor array. Passing the scattered light through the optical elements generates speckle images that appear on the pixels of the photosensor arrays. Based on the pixel shape, a pixel value associated with the speckle image provides a speckle image data signal. When there is translation of the pointing device, a new set of speckle images, each reassembling to a translated version of the previous speckle image, arc generated and another speckle image data signal is generated. The new and the previous speckle image data signals are then used in a motion detection analysis to determine the points of the two data signals that give a displacement value.

    摘要： In order to adaptively determine the original pulse widths of individual pulses of the pulse signal, there are measured the pulse widths of the distorted pulses. A predetermined number of threshold values is preset for such measured pulse widths. The preset threshold values define classes of pulse widths intended to contain pulse widths of pulses which originally had the same pulse widths. The matching between the measured pulse widths and the preset threshold values is improved by means of a statistical evaluation of the measured pulse widths. The apparatus for carrying out the aforementioned method comprises a unit or circuit for measuring the pulse widths of the individual pulses, a unit or circuit for statistically evaluating the measured pulse widths and a unit or circuit for processing the measured pulse widths.

    摘要： A solid-state roller on a pointing device with enhanced features. The solid-state design described herein allows the sensor to be placed on any shape of surface, such as one that has curvature in two directions. In one embodiment, a trench or downward curve contains sensors for detecting finger movement. The user's finger can thus bend about a knuckle in a curved motion to activate the sensor, requiring little or no movement of the finger up and down. The solid-state sensors can be of one of a number of designs. In one embodiment, multiple electrodes are contacted by a finger as it moves. Each electrode is coupled to a capacitive detection circuit, for detecting the change in capacitance as the electrode is contacted by the finger.

    摘要： A capture device for remote, virtual on screen data input by hand annotation comprises at least three functional layers including a bottom rigid layer, a middle pressure sensor layer and a top flexible layer. The bottom rigid layer has a surface that provides a mechanical support for writing. The middle pressure sensor layer is adapted to measuring a pressure array or map on the capture active area and to send data representing the measured pressure to a personal computer. The top flexible touch-sensitive passive LCD display layer includes an LCD surface by which whatever is written down on the LCD is impressed graphically due to its liquid crystal physical properties wherein applied pressure changes the crystal particles orientation and light properties, such that when a stylus presses against a writing surface thereof, it leaves a visible trace allowing the user to produce a drawing though no real ink has flown.

    摘要： In order to reduce the current supply and thus the heating up of relevant components during the processing of binary signals of any desired pulse duration or width, the pulses forming the binary or first signal are converted into a pulsed or second signal which forms a pulse sequence or train consisting of short pulses having different polarities. The individual pulses of the binary signal are converted to short pulses having a first spacing in the pulsed or second signal. The transitions between the pulses of the binary or first signal are converted to pulses having any desired shortened second spacing as compared to the first spacing.
