    • An emitter includes a housing for attaching to a user and for receiving a control circuit having one or more CPUs, a memory coupled to the CPU, a sensing circuit coupled to the CPU for sensing a voltage supplied to the CPU, an emitting circuit coupled to the CPU for being actuated by the CPU to emit a signal out. The housing includes two switches coupled to the CPU, and two further switches for information entering purposes. The emitting circuit may send out the signal by actuating the switches. The functions of the emitter may be tested with the switches.

    • A crt optical filter device includes a transparent plastic sheet and a transparent glass panel, each of which is provided with a transparent conductive circuit layer and a pair of conductors. The outer surface of the glass panel is disposed adjacent to the inner surface of the transparent plastic sheet, while the inner surface thereof is to be disposed adjacent to a screen of a computer monitor. A plurality of spacers, which are made of an insulative material, normally space apart the conductive circuit layers of the transparent plastic sheet and the glass panel. An interface card is connected electrically to the conductors and is to be connected electrically to a computer. The interface card receives analog X and Y signals that correspond to a selected part of the transparent plastic sheet from the conductors when the conductive circuit layers are brought into electrical contact due to application of pressure on the selected part of the transparent plastic sheet. The interface card processes the analog X and Y signals into corresponding digital signals for controlling the computer to move a cursor on the screen of the computer monitor so as to coincide with the selected part of the transparent plastic sheet and for controlling the computer to accomplish predetermined functions.

    • An apparatus for adjusting a minimum liquid level in a liquid supply bottle that utilizes a novel height adjustment means and a method for utilizing such apparatus are provided. In the apparatus, a height adjustment means that is positioned on a base frame of a bottle station for supporting a liquid supply bottle is used. The height adjustment means includes two sliding blocks each having a right-angled triangular cross-section slidingly engaging each other on their hypotenuses. The two sliding blocks may be driven by two screws each threadingly engaging one of the side frames for pushing (or pulling) the sliding blocks toward (or away from) each other such that an elevation of the bottle can be increased (or decreased). The present invention novel apparatus further utilizes a bottle clamp which frictionally engaging the liquid supply bottle and hold it in place while allowing the bottle be moved up and down by slidingly engaging a vertical arm of the clamp with a side frame on the bottle station.
    • 提供一种用于调节利用新颖的高度调节装置的液体供应瓶中的最小液面的装置和一种利用这种装置的方法。 在该装置中,使用位于用于支撑液体供应瓶的瓶站的基座上的高度调节装置。 高度调节装置包括两个滑块,每个滑块具有在其斜边上滑动地彼此接合的直角三角形横截面。 两个滑动块可以由两个螺钉驱动,每个螺栓与两个侧框架中的一个螺纹接合,用于将(或拉)滑动块朝向(或远离)推动(或拉动),使得瓶子的升高可以增加(或减小)。 本发明的新颖设备还利用一种瓶夹,其与液体供应瓶摩擦接合并将其保持在适当位置,同时通过将夹具的垂直臂与瓶站上的侧框滑动地接合来使瓶子上下移动。
