  • Patent number: 9048523
    Abstract: The RF MEMS crosspoint switch comprising a first transmission line and a second transmission line that crosses the first transmission line; the first transmission line comprises two spaced-apart transmission line portions, and a switch element that permanently electrically connects the two spaced-apart transmission line portions; the second transmission line crosses the first transmission line between the two spaced-apart transmission line portions; the RF MEMS crosspoint switch further comprises actuation means for actuating the switch element at least between a first position, in which the switch element is electrically connecting the two spaced-apart transmission line portions of the first transmission line and the first and second transmission lines are electrically disconnected, and a second position, in which the switch element is electrically connecting the two spaced-apart transmission line portions of the first transmission line and is also electrically connecting the two transmission lines together.

  • Patent number: 8593239
    Abstract: The MEMS structure comprises: a flexible membrane (6), which has a main longitudinal axis (6a) defining a longitudinal direction (X), at least one pillar (3, 3?) under the flexible membrane (6), electric lowering actuation means (7) that are adapted to bend down the flexible membrane (6) into a down forced state electric raising actuation means (8) that are adapted to bend up the flexible membrane (6) into an up forced state. The electric lowering actuation means (7) or the electric raising actuation means (8) comprise an actuation area (7c or 8c), that extends under a part of the membrane (6) and that is adapted to exert pulling forces on the membrane (6) simultaneously on both sides of the said at least one pillar (3) in the longitudinal direction (X).

  • Patent number: 7834722
    Abstract: The RF MEMS switch comprising micromechanical switching means that are carried by a substrate (1) and that can be actuated between two positions: a first position (off-state/FIG. 1) and a second position (on-state), and actuation means for actuating the position of the switching means. The micromechanical switching means comprise a flexible membrane (6) which is freely supported by support means (3), which is bendable under the action of the actuation means (7), and which can freely slide relatively to the support means (3) during its bending movement.

  • Publication number: 20090123367
    Abstract: The invention relates to the discovery of novel soluble neutral active Hyaluronidase Glycoproteins (sHASEGPs), methods of manufacture, and their use to facilitate administration of other molecules or to alleviate glycosaminoglycan associated pathologies. Minimally active polypeptide domains of the soluble, neutral active sHASEGP domains are described that include asparagine-linked sugar moieties required for a functional neutral active hyaluronidase domain. Included are modified amino-terminal leader peptides that enhance secretion of sHASEGP. The invention further comprises sialated and pegylated forms of a recombinant sHASEGP to enhance stability and serum pharmacokinetics over naturally occurring slaughterhouse enzymes. Further described are suitable formulations of a substantially purified recombinant sHASEGP glycoprotein derived from a eukaryotic cell that generate the proper glycosylation required for its optimal activity.
