Title: A method of and a network for handling wireless session protocol (wsp) sessions
Inventor: HANSEN HANS H H
IPC: H04M1/72445
Filed: 1999-04-27
Abstract: A communication terminal initiates a Wireless Session Protocol (WSP) session by forwarding a request of data to a server. The request comprises an identification of the requested data and a communication terminal identification number provided by the server. The server, when receiving a request containing a communication terminal identification number, recalls user profile information from an associated database memory corresponding to said communication terminal identification number. The user profile information indicates a data format which will be handled by the communication terminal. Then the server replies to the request by forwarding the requested data in the format defined by the user profile information.

Abstract: A system having a distributed web site is described. The web site is distributed between a client (100), a server (180), and a web server (140).  The client stores a set of predefined applications (106) that correspond to a part of the web site. The applications are formatted according to a first markup language. From the set of predefined applications, the client can generate queries (122). The server receives the queries and generates new, related queries (126). The new queries correspond to a second query protocol.  The second query protocol is used by the web server. The web server generates responses (136) to the new queries and sends these responses to the server.  The responses are formatted according to a second markup language. These responses correspond to the second portion of the web site. The server then converts the responses into new responses (132) that the client can use.

Title: Microelectromechanical device having single crystalline components and metallic components and associated fabrication methods
Inventor: DHULER VIJAYAKUMAR R
IPC: H01H61/02
Filed: 2000-08-07
Abstract: A microelectromechanical (MEMS) device (10) is provided that includes a microelectronic substrate (40), a microactuator (20) disposed on the substrate (40) and formed of a single crystalline material, and at least one metallic structure (30) disposed on the substrate (40) adjacent the microactuator (20) such that the metallic structure (30) is on substantially the same plane as the microactuator (20) and is actuated thereby. For example, the MEMS device may be a microrelay (10). As such, the microrelay (10) may include a pair of metallic structures (32, 34) that are controllably brought into contact by selective actuation of the microactuator. While the MEMS device can include various microactuators, one embodiment of the microactuator is a thermally actuated microactuator which advantageously includes a pair of spaced apart supports (22) disposed on the substrate and at least one arched beam (24) extending therebetween. By heating the at least one arched beam (24) of the microactuator (20), the arched beams (24) will further arch. In an alternate embodiment, the microactuator is an electrostatic microactuator which includes a stationary stator and a movable shuttle. Imposing an electrical bias between the stator and the shuttle causes the shuttle to move with respect to the stator. Thus, on actuation, the microactuator moves between a first position in which the microactuator is spaced apart from the at least one metallic structure to a second position in which the microactuator operably engages the at least one metallic structure. Several advantageous methods of fabricating an MEMS device having both single crystal components and metallic components are also provided.

Title: Temporary bracing system for insulated wall form and method
Inventor: KLASSEN GLEN A
IPC: E04B2/86
Filed: 2001-10-31
Abstract: A system and method for securing an insulated concrete wall form to a bracing structure such as a scaffolding frame to keep the form straight and plumb during construction. The system uses anchoring and tensioning members, which may be formed as pieces separate or integrally as a single piece to hold the bracing structure against insulated panels of the insulated concrete wall form. Openings may be cut through the insulated panels to provide a pathway for the tensioning member. The anchoring member is positioned against an inner face of the insulated panel. A portion of the anchoring member or the tensioning member extends into the wall form concrete receiving space to fix the system in place once the concrete sets. The tensioning member may be disposed through one of the openings, around the bracing structure and through the other opening and around the anchor member to maintain the tension. Alternatively, the tensioning member may be disposed through an interface between upper and lower wall form blocks. The bracing structure may be adjusted to align the wall form vertically.

Title: Manufacture of alloys containing dispersed fine particulate material
Inventor: REEVE MARTIN R
IPC: C22C1/10
Filed: 2001-11-08
Abstract: A method of preparing a metal alloy comprising a dispersion of particles of a first metallic material consisting of one or more refractory hard metals in a matrix of a second metallic material includes establishing a molten body of the second metallic material and introducing solid particles of the first metallic material into the molten body. Alternatively solid particles of a metalloid which reacts with the second metallic material to form particles of the first metallic material may be introduced into the molten body. The first metallic material has a higher melting point than the second metallic material and is substantially insoluble therein. The molten body is then stirred at a rate sufficient to effect shearing of the surfaces of the particles such that the surfaces are wetted by the molten body, and the molten body containing the resultant dispersion is cast in any desired manner.
