  • Publication number: 20110209866
    Abstract: The present invention discloses a corrugated settling cup and a multi-cup uniform flux gas anchor, which belong to oilfield gas-liquid separation devices. The external profile of the cup body of the corrugated settling cup rises in a corrugated shape along an axial direction of the corrugated settling cup, which facilitates rapid aggregation and rise of gas.

  • Publication number: 20110063068
    Abstract: A radio frequency (RF) micro electromechanical system (MEMS) switch formed on a substrate (e.g., a CMOS substrate). The RF MEMS switch includes a micromechanical member including a flexible switch membrane configured to move between an on state and an off state of the RF MEMS switch. The flexible switch membrane includes a first set of fingers on a sidewall thereof to be vertically coupled with a second set of fingers formed at an output of the RF MEMS switch on the substrate, and an actuation member in operable communication with the micromechanical member and configured to thermally actuate the micromechanical member such that the first set of fingers electrically couple with the second set of fingers upon thermal actuation of the micromechanical member to enable transmission of an RF signal.
