Abstract: A cable assembly comprising a termination with at least one conductive, compressible member and a conductive ground shield. The conductive, compressible member may be held within a connector module forming the termination such that the conductive compressive member is pressed against, and therefore makes electrical contact with, both an outer conductive layer of the cable and ground structures within the connector module.

The conductive ground shield may be configured to compress the conductive, compressible member, and to cause the conductive, compressible member to electrically contact the cable's conductive layer. The conductive, compressible member may be formed from a compressible material and may comprise a plurality of conductive particulates configured to provide electrically conductive paths.
Abstract: A keyboard device includes plural key structures, a switch circuit board, an elastic cover and a seal element. The switch circuit board includes a hollow region. The elastic cover is disposed on the switch circuit board. The hollow region is covered by the elastic cover, so that a foreign liquid is prevented from entering the switch circuit board. The seal element is disposed on sidewalls of the switch circuit board. Consequently, a sealed region is formed between the switch circuit board and the elastic cover. When the inner gas within the switch circuit board is changed, the elastic cover is subjected to expansion or contraction. Consequently, the switch circuit board is not subjected to deformation in response to the volume change of the inner gas.

Furthermore, the cell system includes a circuit to be connected at least either between the positive electrode and the first switch or between the negative electrode and the second switch; and a controller configured to shift control timings of the first switch and the second switch from the shut-off state to a connected state according to an electrical capacitance generated between the positive electrode and the negative electrode.
Abstract: A MEA is set in a state where a hydrogen gas is continuously supplied to both an anode-side electrode and a cathode-side electrode. In this state, a current is applied from an external power supply unit to the anode-side electrode and the cathode-side electrode so that the cathode-side electrode has a higher potential and that the current value gradually increases. Upon applying the current in this way, measured voltages between both electrodes measured by a voltage measurement unit are plotted in time series, thereby measuring the voltage transition across the inspection object MEA. A power generation performance inspection of the inspection object MEA is carried out based on the measured voltage transition.
Abstract: A push switch includes a movable contact including a dome part that is shaped like a dome and configured to be inverted in shape when pressed, and a fixed contact including a first fixed contact, the movable contact being configured to be brought into contact with and away from the first fixed contact. The push switch is configured such that an operating load necessary to press the movable contact gradually increases after the movable contact starts to be pressed, decreases thereafter when the dome part is inverted, and increases again when the movable contact is further pressed, and the dome part contacts the first fixed contact after an inflection point at which the decreased operating load starts to increase again.
Abstract: A fuel cell system comprises a fuel cell stack, radiator, cooling water feed passage, cooling water discharge passage, bypass cooling water passage, deionizer, stack side cooling water pump, radiator side cooling water pump, and bypass cooling water control valve. The radiator side cooling water pump and bypass cooling water control valve are controlled to selectively perform one of a stack flow through mode where cooling water flows through at least the fuel cell stack and a stack bypass mode where cooling water does not substantially flow through the fuel cell stack but circulates through the radiator and the bypass cooling water passage.
Abstract: A grounding clamp includes a safety lock-out which locks the operation of the clamp in the absence of a hot-stick. A clamping member cooperates with a frame having an arm, and is selectively biasable by a user to translate the clamping member relative to the frame to clamp a conductor between the clamping member and arm. The lock-out cooperates with the clamping member to prevent the translation of the clamping member unless in the presence of an insulating tool such as a hot-stick.

Abstract: A mounting structure for an energy storage assembly of a circuit breaker comprises an energy storage lever and an energy storage spring, wherein one end of the energy storage lever is an energy storage end which is connected with the energy storage spring, and the other end of the energy storage lever is a driving end. An external force can be applied to the driving end, such that the energy storage lever rotates around a lever fulcrum in the middle of the energy storage lever, thereby extruding the energy storage spring at the energy storage end to finish energy storage. One end of the energy storage spring is connected and mounted with the energy storage lever, and the other end of the energy storage spring is mounted in a base support. An energy storage mounting shaft which can be considered as a rotating fulcrum is also arranged in the middle of the energy storage lever. The driving end is stressed, such that the energy storage lever rotates around the energy storage mounting shaft.

Abstract: A safety lockout device for switchgear includes a movable member adapted to be moved from a first position to a second position. A switch is adapted to electrically isolate a motor in the switchgear and a blocking arm is coupled to a shaft of the motor. In the first position, the movable member engages the switch to close the electrical motor circuit and the blocking arm is free to rotate with the motor shaft. In the second position, the movable member moves away from the switch so that the switch is in an open circuit state disconnecting power to the motor and a portion of the movable member is moved to a position whereby the blocking arm engages the movable member to prevent rotation of the motor shaft and a change of state of the switchgear. The position of the movable member relative to the switch provides a visual indication of the operating state of the switchgear.

The bridge assembly includes first and second hinge parts. The first hinge part has a first pivot coupling portion and a first connecting portion. The second hinge part has a second pivot coupling portion and a second connecting portion, wherein the first and second connecting portions are connected on an axis, and the first and second hinge parts rotate with respect to the axis. The first and second supporting parts are coupled to two ends of the first and second pivot coupling portions, respectively. The attractable element is disposed on the second hinge part. The magnet is correspondingly located under the attractable element for providing a magnetic force, so that the attractable element is attracted and positioned by the magnetic force.
Abstract: A restraint system is used to restrain a movable switch blade of a disconnect switch in order to prevent accidental closure of the switch blade. In this regard, the restraint system has a sheath that is positioned over an end of the switch blade, and the sheath is tethered to a support structure so that tension in the tether resists movement of the switch blade toward a conductive jaw. Thus, current is prevented from flowing through the disconnect switch until the sheath is manually removed from the switch blade.
