    • A varistor-based voltage suppression circuit is coupled to a power distribution system having at least one power line and at least one neutral line. A varistor is coupled directly to the power and neutral lines of the distribution circuit so that the electric current travels across at least one planar surface of the varistor, thus eliminating one or more leads from the distribution circuit to the varistor circuit. The suppression circuit may be a single varistor or a number of varistors in parallel with a number of lines in the distribution circuit.
    • 基于变阻器的电压抑制电路耦合到具有至少一个电力线和至少一个中性线的配电系统。 变阻器直接耦合到配电电路的电力线和中性线,使得电流穿过变阻器的至少一个平坦表面,从而消除了从分配电路到压敏电路的一个或多个引线。 抑制电路可以是与分配电路中的多条线路并联的单个压敏电阻器或多个压敏电阻器。

    • A cuff for measuring volume and change in volume of a body appendage includes a hollow, rigid tube having an inner surface; and a bladder having an inner surface and an outer surface, the ends of the bladder being sealed to the ends of the tube to create an enclosed internal volume between the inner surface of the bladder and the inner surface of the tube and an external volume defined by the outer surface of the bladder and surrounded by the internal volume, the bladder having a normal, relaxed state, in which the internal volume is filled with a fluid and a retracted state in which the fluid is evacuated from the internal volume. Two stiffener ribs placed on the inner surface of the bladder, parallel to each other and to the lengthwise axis of the tube at diametrically opposite positions. A plurality of emitters and detectors arranged in a linear array are embedded in one of the ribs, so as to emit and detect light through the bladder. A fluid port extending through the tube and communicating with the internal volume, through which the internal volume can be filled with or emptied of the fluid.
    • 用于测量身体附件的体积和体积变化的袖带包括具有内表面的中空刚性管; 以及具有内表面和外表面的囊,所述囊的端部被密封到所述管的端部,以在所述囊的内表面和所述管的内表面之间产生封闭的内部容积,并且限定了外部容积 通过膀胱的外表面并被内部体积包围,气囊具有正常的松弛状态,其中内部容积填充有流体和从内部空间排出流体的缩回状态。 两个加强肋布置在囊的内表面上,在直径相对的位置处彼此平行并且与管的纵向轴线平行。 布置成线性阵列的多个发射器和检测器嵌入其中一个肋中,以便通过膀胱发射和检测光。 流体端口延伸穿过管并与内部容积连通,内部容积可以通过该容积填充或排空流体。
