摘要： A cassette for controlling the flow of IV fluid from a patient to a source. The cassette preferably includes, along the fluid passage through the cassette, first and second membrane-based valves on either side of a pressure-conduction chamber, and a stopcock-type valve. The stopcock valve is preferably located downstream of the second membrane-based valve, which is preferably located downstream of the pressure-conduction chamber. The stopcock control valve preferably has two rigid cylindrical members with complementary surfaces, wherein one member includes a tapered groove defined on its complementary surface. The two complementary surfaces define a space therebetween, instead of having an interference fit, and a resilient sealing member is disposed in this space. When the first and second rigid members are in an open position with respect to each other, the sealing member defines an aperture through which fluid communication is provided between the fluid-path portions defined respectively by the two rigid members. When the first and second rigid members are in the closed position with respect to each other, the sealing member provides a seal preventing flow between the fluid-path portions. The membrane defining the valving chamber of the second membrane-based valve is preferably large and resilient, so that the valving chamber may provide a supply of pressurized intravenous fluid to the patient, when the valve is closed and the stopcock valve provides a restriction downstream of the valve. The pressure-conduction chamber preferably has a membrane that is stable in the empty-chamber position but relatively unstable in the filled-chamber position.

摘要： A system and method for controlling an electrically controlled pressure relief valve may use a soft position control loop to control the position of the valve. A pressure relief valve may also include a modified orifice shape to improve stability, to uniformly distribute the effective bandwidth over the valve operating range, and to provide a tunable default mode.

摘要： To decrease the time required to charge parasitic capacitances, and to thereby increase the maximum permissible switching frequency to which a logic circuit can respond, a GaAs device is disclosed having a current-injecting circuit that generates an initial pulse of capacitor-charging current during a "0"-to-"1" transition in the output state of a GaAs device. The pulse is sufficiently large to quickly charge the parasitic capacitances, and of sufficiently brief duration so that a minimum line width is permissible which is substantially equivalent to that which would be applicable in the absence of the current-injecting circuit.
摘要翻译：为了减少对寄生电容进行充电所需的时间，并且由此增加逻辑电路可以响应的最大允许开关频率，公开了具有电流注入电路的GaAs器件，该电流注入电路在期间产生电容器充电电流的初始脉冲 GaAs器件的输出状态下的“0”到“1”跃迁。脉冲足够大以快速充电寄生电容并且具有足够短的持续时间，使得允许的最小线宽度基本上等于在不存在电流注入电路的情况下适用的线宽。
