    • An apparatus and method for determining characterizing attributes of an actuator is provided. An actuator may be moved to a maximum capacitance position. At the maximum capacitance position, an initial measurement of the actuator capacitance is made. The actuator is moved a predetermined increment toward a first extreme position, and the actuator capacitance is again measured. If the capacitance changed by a threshold amount, the signal preceding the signal that caused the actuator to move is recorded as an approximate response curve end point, or the first extreme position. The actuator is again moved a predetermined increment toward a second extreme position. After each move, the capacitance is measured. If it is determined the capacitance did change by a threshold amount from the previously measured capacitance, the signal related to the previously measured capacitance is recorded as an approximate response curve end point, or the second extreme position.
    • 提供了一种用于确定致动器的特征属性的装置和方法。 致动器可以移动到最大电容位置。 在最大电容位置,进行致动器电容的初始测量。 致动器朝向第一极限位置移动预定增量,并再次测量致动器电容。 如果电容变化了阈值,则将导致执行器移动的信号前面的信号记录为近似响应曲线终点或第一极限位置。 致动器再次向第二极限位置移动预定增量。 每次移动后,测量电容。 如果确定电容确实从先前测量的电容改变阈值量,则将与先前测量的电容相关的信号记录为近似响应曲线终点或第二极限位置。

    • A method of synthesizing multi-level raster shapes directly from outlines describing ideal shapes is disclosed. A raster shape suitable for approximating the ideal shape in a raster display device is synthesized by dividing a plane into a plurality of pixel areas according to a pixel grid, then by representing the shape as one or more arcs in the plane, where the arcs collectively, and in conjunction with an insideness criterium, divide the plane into an inside region and an outside region, and then by separating the pixels into inside pixels, outside pixels, and boundary pixels. The raster shape comprises coverage values assigned to each pixel in the plane, where inside pixels are assigned a coverage value of 1, outside pixels a coverage value of 0 and the boundary pixels a coverage value between 0 and 1 approximating the degree to which the boundary pixel is covered by the inside of the outline. Initially, boundary pixels are assigned a coverage value of 0 or 1 based on a pixel-coverage criterium, and then it is corrected by a correction value resulting in a coverage value between 0 and 1. The correction value for a pixel might be a numerical value indicating the fraction of the pixel covered by the correction region; the correction value may also depend on the geometry of the correction region represented by the valve and the region's location within the pixel. The correction region of a boundary pixel is the signed difference between the region represented by the initial coverage value assigned to the pixel and the actual region of the pixel covered by the inside of the outline.
    • 公开了直接从描述理想形状的轮廓合成多级光栅形状的方法。 通过根据像素网格将平面划分为多个像素区域,然后通过将该形状表示为平面中的一个或多个弧来合成光栅显示设备中适合于近似理想形状的光栅形状,其中弧线集中 ,并结合一个绝对标准,将平面分成内部区域和外部区域,然后将像素分离成内部像素,外部像素和边界像素。 栅格形状包括分配给平面中的每个像素的覆盖值,其中内部像素被分配覆盖值1,外部像素覆盖值为0,边界像素覆盖值在0和1之间近似于边界的程度 像素被轮廓的内部覆盖。 首先,边界像素根据像素覆盖率标准分配0或1的覆盖值,然后通过校正值来校正,导致0和1之间的覆盖值。像素的校正值可以是数字 指示由校正区域覆盖的像素的分数的值; 校正值也可以取决于由阀表示的校正区域的几何形状和区域在像素内的位置。 边界像素的校正区域是由分配给像素的初始覆盖值和由轮廓内部覆盖的像素的实际区域表示的区域之间的有符号差。

    • A method and apparatus for minimizing the visual degradation of a typeface wherein the need for the manual input of skilled technicians is eliminated and the important visual components of each character and the relationship of the visual components of each character with the other characters of the typeface are preserved. The characters are analyzed to determine the visual components in the horizontal and vertical direction which comprise each character and the priority of adjustment. Using the visual components determined, starting with the highest priority component, the coordinates describing each character are adjusted according to rules which are dependent upon whether the strokes formed are oriented in the horizontal or vertical direction. The adjustment of the lower priority visual components is dependent on the previously aligned components. The important visual components in the diagonal direction are subsequently adjusted in accordance with similar sized visual components in the horizontal and vertical direction wherein the dimensions of the adjusted horizontal and vertical components are maintained.
