The switch can include a beam coupled to an anchor on a substrate by one or more hinges. The switch can include control electrodes, disposed on a surface of the substrate, for electrically controlling the beam.

Abstract: High voltage micro-electromechanical systems (MEMS) switches are described. A MEMS teeter-totter switch can include a beam coupled to an anchor on a substrate and two control electrodes, disposed on a surface of the substrate. A control circuit may include an isolator that provides an isolated activation voltage to a voltage supply and control circuit. The voltage supply and control circuit uses the isolated activation voltage to supply a control voltage to one of the control electrodes with respect to a first reference voltage, causing the beam to provide an input voltage received from an input terminal to a contact electrode of the MEMS teeter-totter switch electrically connected to an output terminal. The input voltage is applied on the beam with respect to a second reference voltage different from the first reference voltage.

Abstract: The present invention relates to stabilizer composition for halogen-containing polymer. It has recently been found that tin-based thermal stabilizers with a bridging alkyl group between two tin centers are effective stabilizers while having effectively double the molecular weight of the corresponding non-alkyl bridged stabilizer. It is expected that ongoing experimentation will confirm that the alkyl bridged stabilizers have much lower volatility which leads to greater retention of the stabilizer in the finished article.

Abstract: The present invention relates to catalyst compositions. More particularly, the present invention relates catalyst compositions comprising at least one alkyl bridge group. The catalyst of the present invention has been shown to provide higher filterability than provided by non-bridged catalysts when used in ester reactions, and provide lower extractability than provided by non-bridged catalysts when used in urethane reactions. The present invention is expected to be catalytically active in the same way to all ester bonds, urethane bonds, silicones, siloxanes, organic tins.
