    • 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.
    • 用于输入诸如操纵杆的计算机信号的用户输入系统具有由壳体可移动地接收的细长构件或手柄。 手柄能够沿着X,Y和Z轴至少三个垂直方向移动,并且能够围绕三个轴中的至少一个旋转。 在第一实施例中,一对发光二极管(“LED”)安装在手柄的端部并朝向壳体的内部。 LED被选通以将光向下投射到壳体中。 诸如二维位置感测装置(“PSD”),两个一维PSD或四象限光电二极管的光检测元件与LED相对定位,并且安装到壳体以接收来自LED的光 产生信号。 信号从模拟转换为数字,并输入到微处理器。 微处理器采用三角法来计算手柄的位置和方向(即旋转),并将坐标输出到主计算机。 操纵杆优选地包括产生信号的开关和产生可变信号的可滑动构件,所有这些都被输出到计算机。 在第二实施例中,LED被安装到壳体以将光向上突出,光检测单元安装在手柄的端部。

    • 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.
    • 无线计算机输入系统使用笔式输入设备和接收器。 笔式输入装置包括LED,至少一个开关,可充电电池和控制电路。 控制电路在激活开关时向LED提供信号,并提供功率管理功能,允许笔在空闲时段节省电力。 接收机包括连接到位置计算电路的一个或多个光检测元件。 光检测元件是二维PSD,两个一维PSD或四分光电二极管。 可选的透镜,光学滤光片和多孔板位于光检测元件之前,提高了系统的信噪比。 计算电路接收来自光检测元件的信号,对它们进行数字化,并计算输出到主计算机的笔的坐标。 连接到计算电路的再充电电路允许笔在接收器内充电,或者当电池缺少足够的电力时由电线连接。

    • A computer joystick capable of detecting the position of a control stick in the X and Y directions, as well as the rotational (R) position of the control stick to allow three positional measurements to be made. The joystick uses an optical position detection circuit with a pair of light sources mounted either on the control stick or a printed circuit board mounted beneath the control stick. A photodetector assemble is mounted opposite the pair of light sources to detect light from the light sources. The distribution of the light intensity is indicative of the position of the control stick in the X, Y, and R directions. A single coil spring is used to return the control stick to a resting position when released by the user. The single spring provides an even return force that is dependent on displacement from the resting position. The bottom portion of the control stick moves in a three dimensional arcuate path as the control stick is manipulated by the user. To simplify operation of the optical position detection circuit, the joystick uses a mechanical three dimensional to two dimensional mechanical converter assembly to convert the arcuate movement of the control stick to two dimensional movement of the light sources.
    • 一种能够检测控制棒在X和Y方向上的位置以及控制棒的旋转(R)位置以允许进行三个位置测量的计算机操纵杆。 操纵杆使用安装在控制棒上的一对光源或安装在控制棒下方的印刷电路板的光学位置检测电路。 光电检测器组装安装在一对光源的对面以检测来自光源的光。 光强度的分布表示控制棒在X,Y和R方向上的位置。 当用户释放时,使用单个螺旋弹簧将控制杆返回到静止位置。 单个弹簧提供平衡的返回力,其依赖于从静止位置的位移。 当控制棒被用户操纵时,控制棒的底部以三维弧形路径移动。 为了简化光学位置检测电路的操作,操纵杆使用机械三维至二维机械转换器组件,以将控制棒的弓形运动转换成光源的二维运动。
