    Abstract: A digital pen that has an ink writing tip includes a laser on a pen body that directs light toward paper across which the writing tip is stroked. A diffraction grating reflects a reference beam and passes a scattered beam from the substrate toward translation detectors, which consequently receive interference patterns of light. A processor receives the signals from the detectors, generates position signals, and stores the signals. Also, a bar code detector receives a bar code beam from the substrate, and a three dimensional force sensor outputs a signal representative of multidimensional forces applied to the pen. Subsequently, the signals are uploaded to a host processor which combines them to produce rotation-corrected relative positions (if no bar coded paper is used) or rotation- corrected absolute positions (if bar coded paper is used) that can be used to render alpha-numeric characters or graphical representations.

    Abstract translation: 具有墨水笔尖的数字笔在笔体上包括激光器，该激光器将光引导朝向书写笔尖被抚摸的纸张。 衍射光栅反射参考光束并将来自衬底的散射光束传向平移检测器，从而接收光的干涉图案。 处理器接收来自检测器的信号，产生位置信号并存储信号。 而且，条形码检测器从基板接收条形码束，并且三维力传感器输出表示施加到笔的多维力的信号。 随后，信号被上传到主处理器，该主处理器将它们组合以产生可用于渲染alpha的经旋转校正的相对位置（如果不使用条形码纸）或经旋转校正的绝对位置（如果使用条形码纸） - 数字字符或图形表示。

    Abstract: A structure is provided for a user-manipulable input device, such as an in-keyboard, joystick-type device, for allowing a user to provide input to a computer graphical user interface (GUI). The structure includes a user-manipulable, articulating member 20, and a plurality of stationary, electrically conductive sensors 30. The articulating member also has an electrically conductive member. The physical disposition of the articulating member and the sensors provides narrow gaps 33, across which are measurable capacitances. As the user manipulates the articulating member, the capacitances change in value. Circuitry produces signals related to the capacitances, and the signals are processed, according to a transfer function, to generate GUI input signals. The sensors are preferably sensing electrodes, incorporated into a circuit board 28. The articulating member is preferably a cone-shaped member 22, having a conductive surface which faces the sensors. The articulating member is mechanically coupled to the board holding the sensors by a flexing member 32 that biases the articulating member to a quiescent position.

    Abstract: A DIGITAL PEN (10) THAT HAS AN INK WRITING TIP (28) INCLUDES A LASER (32) ON A PEN BODY (14) THAT DIRECTS LIGHT TOWARD PAPER ACROSS WHICH THE WRITING TIP IS STROKED. A DIFFRACTION GRATING (40) REFLECTS A REFERENCE BEAM (48) AND PASSES A SCATTERED BEAM (36) FROM THE SUBSTRATE (12) TOWARD TRANSLATION DETECTORS (42-46), WHICH CONSEQUENTLY RECEIVE INTERFERENCE PATTERNS OF LIGHT. A PROCESSOR (22) RECEIVES THE SIGNALS FROM THE DETECTORS, GENERATES POSITION SIGNALS, AND STORES THE SIGNALS. ALSO, A BAR CODE DETECTOR (50) RECEIVES A BAR CODE BEAM (38) FROM THE SUBSTRATE, AND A THREE DIMENSIONAL FORCE SENSOR OUTPUTS A SIGNAL REPRESENTATIVE OF MULTIDIMENSIONAL FORCES APPLIED TO THE PEN. SUBSEQUENTLY, THE SIGNALS ARE UPLOADED TO A HOST PROCESSOR (31) WHICH COMBINES THEM TO PRODUCE ROTATION-CORRECTED RELATIVE POSITIONS (IF NO BAR CODED PAPER IS USED) OR ROTATION-CORRECTED ABSOLUTE POSITIONS (IF BAR CODED PAPER IS USED) THAT CAN BE USED TO RENDER ALPHA-NUMERIC CHARACTERS OR GRAPHICAL REPRESENTATIONS.FIGURE 1.
