摘要： A method, apparatus, and system for tracking movement of a device are described. The method includes steps of implementing a first tracking subsystem for tracking positions of a device against a surface, determining whether to implement a second tracking subsystem for tracking positions of the device against the surface, capturing data corresponding to a location on the surface, and determining a position of the device against the surface based on the captured data. The position of the device can then be transmitted to a host computer and used in an application program. The first and second tracking subsystems may be a relative and an absolute tracking subsystem respectively.

摘要： An optical mouse includes a housing movable across a work surface with a source of non-coherent light in the movable housing for illuminating the work surface at a low or grazing angle of incidence, and may include a two dimensional array of photodetectors, each of which may produce an output in response to light reflected from surface irregularities on the illuminated work surface. The housing may include a memory for storing the photodetector outputs captured at one or more times. Circuitry in the housing may track movement of the housing relative to the work surface by comparing at least some of the photo detector outputs captured at a first time with at least some of the photo detector outputs captured at a second time depending upon whether a characteristic condition in the photo detector outputs, such as uniformity, is detected. The circuitry may track movement of the housing by comparing light reflected from the surface irregularities a first time with light reflected there from at a second time unless a detectable image is not included therein.

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. Signal may be sent to a computer related to movement of the housing.

摘要： A CMOS power-on reset circuit has a delay capacitor to provide a predetermined delay period. Charging and discharging of the delay capacitor is controlled by the state of a flipflop circuit. An input comparator monitors a power supply input voltage. An invalid input voltage level immediately changes the reset output signal to the invalid state and discharges the capacitor. Even after the input voltage has recovered to a valid level, recharging the capacitor is delayed until the capacitor has substantially discharged, thereby ensuring at least a predetermined delay period after the last fault condition. The delay capacitor is coupled in a feedback configuration so as to lower the threshold voltage when the delay capacitor voltage indicates to the valid state, to allow limited power supply sag, for example due to motor start-up, without resetting the circuit. Multiple power supply voltages are continuously monitored in a CMOS integrated configuration by additional input scaling resistor networks and input comparators, all coupled to the common 2-level threshold voltage node.
