    摘要: A system to detect a pressure difference between the interior of a cabin of an aircraft and the exterior of the aircraft. The system includes a window arrangement having a first windowpane with a first surface and an opposite second surface and is adapted to be mounted in an aircraft such that the first surface of the first windowpane faces the exterior of the aircraft and is subjected to ambient outside atmospheric pressure and the second surface faces the cabin interior, and a pressure sensor including a first pressure port. The first windowpane includes a first air passage opening extending between the first and second surfaces of the first windowpane, and the pressure sensor is sealingly connected to the first air passage opening such that the first pressure port of the pressure sensor is subjected to pressure acting on the first surface of the first windowpane.

    摘要: One or more electroactive polymer (EAP) strips are circumferentially or lengthwise embedded or mounted around the fluid passage member. The EAP strips are configured to function as a pump when a prescribed electrical charge is applied and removed from the EAP strips, which causes the EAP strips to expand and constrict accordingly. A series of these strips may be mounted along a portion of the fluid passage member and electrically actuated in a prescribed manner to exert a squeezing force around the fluid passage member, which functions to pump fluid through the fluid passage member. The EAP strips also change electrical characteristics (e.g., capacitance, resistance) independent of the applied actuation as they are stretched, so they may be used to measure fluid pressure and/or fluid flow rate.

    摘要: The ultra-precision micro-differential pressure measuring device comprises a device body 1 having an inner space part therein, a pressure receiving plate 3 which is installed inside the inner space of the device body 1 and divides the said inner space hermetically into a lower space 7 and an upper part space 8, an electronic weighing and pressure converting device 2 which is installed in the lower space 7, and supports and secures the pressure receiving plate 3, and a liquid sealing part R which liquid-seals the outer peripheral part of the afore-mentioned pressure receiving plate 3 and maintains the air-tightness between the lower space 7 and the upper space 8. A micro-differential pressure between a pressure P1 inside the upper space 8 and a pressure P2 inside the lower space 7 is measured by the electronic weighing and pressure converting device 2 through the pressure receiving plate 3.
