Title: Microelectromechanical systems including thermally actuated beams on heaters that move with the thermally actuated beams
Inventor: COWEN ALLEN BRUCE
IPC: H01H1/00
Filed: 2001-02-08
Abstract: Improved microelectromechanical structures include spaced-apart supports on a microelectronic substrate and a beam that extends between the spaced-apart supports and that expands upon application of heat thereto to thereby cause displacement of the beam between the spaced-apart supports. A heater, located on the beam, applies heat to the beam and displaces with the beam as the beam displaces. Therefore, heat can be directly applied to the arched beam, thereby reducing thermal loss between the heater and the arched beam. Furthermore, an air gap between the heater and arched beam may not need to be heated, thereby allowing improved transient thermal response. Moreover, displacing the heater as the arched beam displaces may further reduce thermal loss and transient thermal response by reducing the separation between the heater and the arched beam as the arched beam displaces.

Title: .alpha.-olefins and olefin polymers and processes therefor
Inventor: ARTHUR SAMUEL DAVID
IPC: C08F132/04
Filed: 1996-01-24
Abstract: Disclosed herein are processes for polymerizing ethylene, acyclic olefins, and/or selected cyclic olefins, and optionally selected olefinic esters or carboxylic acids, and other monomers. The polymerizations are catalysed by selected transition metal compounds, and sometimes other co-catalysts. Since some of the polymerizations exhibit some characteristics of living polymerizations, block copolymers can be readily made. Many of the polymers produced are often novel, particularly in regard to their microstructure, which gives some of them unusual properties. Numerous novel catalysts are disclosed, as well as some novel processes for making them. The polymers made are uxful as elastomers, molding resins, in adhesives, etc. Also described herein is the synthesis of linear a-olefins by the oligomerization of ethylene using as a catalyst system a combination of a nickel compound having a xlected .alpha.-diimine ligand and a selected Lewis or Bronsted acid, or by contacting selected $(a)-diimine nickel complexes with ethylene.

Abstract: An efficient, integrated solution for processing input transport streams, such as MPEG2 streams. MPEG packets are routed from an input circuit card to one or more various target processor cards in a chassis.      The processor cards provide functions such as transcoding, multiplexing, splicing, scrambling, and so forth. Each processor card also has a router for routing a received packet to one of a number of available hardware processing paths. Customized IP-type routing is used to encapsulate and route the packets to the processor cards, where a destination address field provides source information regarding a received packet, such as a source slot and port, and a packet identifier (PID). The routers are configured by a system host computer to efficiently use the available resources of the processor cards.

Title: Selecting flip phone operating mode using flip position
Inventor: CLAXTON DANIEL D
IPC: H04M1/72403
Filed: 2000-05-05
Abstract: A flip cover and hinge operate as a rotary switch to select the mode of operation of a communications device. Multiple contacts are located on the sides of the inner surface of the flip cover and a single contact is located on each side of the body of the communications device.  Each contact located on the sides of the inner surface of the flip cover represents a different mode of operation for the communications device. As the flip cover rotates from a closure position to its final position as a stand, the mode of operation of the communications device changes as the contact from the body of the communications device connects with one of the contacts on the flip cover. Three modes of operation are presently implemented: the KEYPAD mode, the SMARTPHONE mode, and the SPEAKERPHONE mode.
