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： An optical port with directional control. The port includes a transmitter, receiver, and first actuator. The transmitter generates an outgoing light signal that propagates in a transmission direction in response to an outgoing electrical signal. The receiver receives an incoming light signal and generating an incoming electrical signal therefrom, the receiver having a reception direction aligned with the transmission direction. The first actuator alters the transmission direction of the outgoing light signal in response to a first control signal. In one embodiment, the first actuator determines the direction of the outgoing light signal in a first plane, and a second actuator controls the direction of the outgoing light signal by an amount determined by a second control signal. The second actuator controls the direction of the outgoing light signal in a second plane that is orthogonal to the first plane. The actuators can be constructed from beam deflectors that utilize moveable mirrors to alter the transmission direction. In one embodiment, the deflector includes an array of mirrors, each mirror rotating about an axis through the mirror. Actuators that rotate the transmitter and reflector may also be utilized.

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.
