    • An apparatus for testing pixels of a flat panel display has a palette for holding a TFT substrate, drive signal source units, and predetermined voltage source units. The palette is grounded. One of the predetermined voltage source units applies a predetermined voltage to a Cs electrode of each of pixels constituting the TFT substrate so that the predetermined voltage is used as a reference voltage of the TFT substrate 11. The drive signal source units supply drive signals to a gate electrode G and a source electrode S respectively in each of the pixels constituting the TFT substrate. The voltages of the drive signals are floated by predetermined voltages given by the corresponding predetermined voltage source units respectively.

    • A floating interface assembly provides signal paths between an integrated circuit (IC) test head and contact pads on a load board or probe card accessing an IC to be tested. Pogo pins or other contactors for contacting the contact pads are mounted on the interface assembly and linked to the test head by flexible conductors. The interface assembly is attached to the test head by springs to allow it the freedom to rotate to some extent about any axis. As the test head approaches the contact pads, alignment pins engage and orient the interface assembly so that its contactors will mate with the contact pads. As the contactors come into contact with the contact pads, the interface assembly adjusts the plane of the contactors so as to evenly distribute contact pressure over all contactor pads.
    • 浮动接口组件提供集成电路(IC)测试头和访问要测试的IC的负载板或探针卡上的接触焊盘之间的信号路径。 用于接触接触垫的Pogo引脚或其他接触器安装在接口组件上,并通过柔性导体连接到测试头。 接口组件通过弹簧连接到测试头,以允许其在任何轴线上自由旋转到某种程度。 当测试头靠近接触垫时,对准销接合和定向接口组件,使得其接触器将与接触垫配合。 当接触器与接触垫接触时,接口组件调节接触器的平面,以便在所有接触器垫上均匀分布接触压力。

    • A spacecraft includes heat-generating payload equipment, and a heat transport system with a cold plate thermally coupled to the equipment and a capillary-wick evaporator, for evaporating coolant liquid to cool the equipment. The coolant vapor is coupled to a condenser and in a loop back to the evaporator. A heated coolant reservoir is coupled to the loop for pressure control. If the wick is not wetted, heat transfer will not begin or continue. A pair of check valves are coupled in the loop, and the heater is cycled for augmentation pumping of coolant to and from the reservoir. This augmentation pumping, in conjunction with the check valves, wets the wick. The wick liquid storage capacity allows the augmentation pump to provide continuous pulsed liquid flow to assure continuous vapor transport and a continuously operating heat transport system. The check valves are of the ball type to assure maximum reliability. However, any type of check valve can be used, including designs which are preloaded in the closed position. The check valve may use any ball or poppet material which resists corrosion. For optimum performance during testing on Earth, the ball or poppet would have neutral buoyancy or be configured in a closed position when the heat transport system is not operating. The ball may be porous to allow passage of coolant vapor.
