    • The disclosed commercial coin-operated scale-platform massager has a frame, a foot platform, and means including a weight cell for supporting the foot platform relative to the frame. The weight cell provides the primary support for the foot platform, and is distorted by the weight of a person standing on the foot platform and calibrated to determine the weight of the person. A driving vibrator in the form of an electric motor having an eccentric weight keyed to its output shaft is mounted relative to the foot platform, operable when the driving vibrator is activated to vibrate the foot platform relative to the frame. Snubber means allow limited movement of the foot platform relative to the frame. A printer may provide a readout for a permanent record of any information including the weight of the user.
    • 所公开的商业投币式平台按摩器具有框架,脚踏台和包括用于相对于框架支撑脚踏平台的重量单元的装置。 重量单元为脚平台提供主要支撑,并且由于站在脚踏台上的人的重量而变形,并被校准以确定人的重量。 具有与其输出轴相连的偏心重物的电动机形式的驱动振动器相对于脚踏平台安装,当驱动振动器被启动以相对于框架振动脚踏平台时可操作。 缓冲装置允许足平台相对于框架的有限运动。 打印机可以提供包括用户权重的任何信息的永久记录的读出。

    • Improved optical means for automatically controlling or monitoring the position of a relatively moving member such as a tool tip in a numerically controlled machine tool has an image of a region of a datum line projected on to a slit in an optical system. Light passing through the slit falls on to a photoelectric detector device which comprises an array of discrete elements. The elements are electronically scanned sequentially and an electric circuit is provided to produce an output signal when a preset change in incident light intensity is detected by any of the photoelectric elements thus indicating the presence of the movable member at the datum line. There may be two slits projecting images of the region around two transverse datum lines on to two separate arrays so that the movable member can be controlled in two dimensions. Alternatively, in place of two separate arrays and two slits a single two dimensional array may be provided suitably masked.
    • 用于在数控机床中自动控制或监视诸如工具尖端的相对移动构件的位置的改进的光学装置具有投影到光学系统中的狭缝的基准线的区域的图像。 通过狭缝的光落在光电检测器装置上,该光电检测器包括一组离散元件。 这些元件被依次电子扫描,并且当由任何光电元件检测到入射光强度的预设变化从而指示在基准线处存在可动构件时,提供电路以产生输出信号。 可以存在将两个横向基准线周围的区域的图像投影到两个分开的阵列上的两个狭缝,使得可移动部件可以被二维地控制。 或者,代替两个单独的阵列和两个狭缝,可以适当地掩蔽单个二维阵列。
