    摘要： A user input system for inputting computer signals, such as a joystick, has an elongated member or handle that is movably received by a housing. The handle is capable of moving in at least three perpendicular directions, i.e., along X, Y and Z axes, and is capable of being rotated about at least one of the three axes. In a first embodiment, a pair of light emitting diodes ("LEDs") are mounted at an end of the handle and oriented toward the interior of the housing. The LEDs are strobed to alternately project light downward into the housing. A light detecting element, such as a two-dimensional position sensing device ("PSD"), two one-dimension PSDs, or a four quadrant photodiode, is positioned opposite the LEDs, and mounted to the housing to receive the light from the LEDs to produce signals. The signals are converted from analog to digital and input to a microprocessor. The microprocessor, employing trigonometric methods, calculates the position and orientation (i.e., rotation) of the handle and outputs the coordinates to a host computer. The joystick preferably includes switches that produce signals and a slidable member that produces a variable signal, all of which are also output to the computer. In a second embodiment, the LEDs are mounted to the housing to project the light upward and the light detecting unit is mounted at the end of the handle.

    摘要： The wireless computer input system uses a pen-type input device and a receiver. The pen-type input device includes an LED, at least one switch, a rechargeable battery, and a control circuit. The control circuit provides signals to the LED upon activation of the switch, and provides for power management functions allowing the pen to conserve power during idle periods. The receiver includes one or more light-detecting elements connected to position computation circuitry. The light-detecting element or elements are either a two-dimensional PSD, two one-dimensional PSDs or a four division photodiode. Optional lenses, optical filters, and apertured plates are positioned before the light-detecting element(s), improving the signal-to-noise ratio of the system. The computation circuitry receives the signals from the light-detecting element(s), digitizes them, and computes the coordinates of the pen which are output to a host computer. A recharging circuit, connected to the computation circuit, allows the pen to be recharged within the receiver or connected by a cord when the battery lacks sufficient power.

    摘要： A computer command and pointing device that attaches directly to the computer or keyboard without the need for external electrical cables. A BallPoint.TM. mouse has a multi-axis mechanical engagement assembly that allows the mouse to be inserted into a recess in the computer or keyboard and have its weight fully supported by the engagement assembly. The engagement assembly provides tight mechanical coupling between the mouse and the recess, but permits the disconnection of the mouse if excessive force is applied to the mouse. The engagement assembly includes an electrical connector that permits the coupling of electrical signals between the mouse and the computer. The connector pins in the electrical connector are individually spring-loaded to allow the connector pins to recede into the electrical connector when force is applied. A mating electrical connector plate, mounted within the recess, is a flat plate made of an insulating material with electrically conductive pads on the surface thereof. The connector pins of the electrical connector electrically couple electrical signals between the mouse and the computer when the engagement assembly mechanically couples the mouse into the recess. The electrical connector does not require precise alignment of the engagement assembly when installing or removing the mouse. If excessive force is applied to the mouse, it disconnects from the recess without damaging the mouse or the computer.
