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. In some embodiments, these connections may be formed using a conductive, compressible member with an opening configured to receive the end of the cable therethrough. 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.

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.

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.
