Abstract: An accommodating intraocular lens (20) is disclosed that provides vision accommodation in response to contraction of an eye's ciliary muscle (60). This lens comprises a deformable elastic dynamic lens (26) comprising a lensshapinging member (30, 34) in contact with peripheral edge regions of the dynamic lens for enabling compressive deformation thereof for changing the lens surface curvature. Included are an elastically flexible coilmember (32) mounted around the lens-shaping member. A first lens-supporting member (52) has a proximal end region engaging the flexible coil member and a second lenssupporting member (54) has a proximal end region connected to the lens- shaping member. For implantation in the capsular bag of an aphakic eye, both lens-support ing members (52, 54) either attach to the capsular bag or bear directly against opposite regions of the ciliary body. For implatation in the anterior chamber of a phakic eye the first lens-supporting member (52) bears directly against the cil iary body the second one (54) attaching the lens (20) to the iris (66).

Title: System and method for dynamically altering connections in a data processing network
Inventor: FERNANDES LILIAN SYLVIA
IPC: G06F15/00
Filed: 2002-10-28
Abstract: A data processing network and system in which a network connection is enabled to migrate among a multitude of available servers and/or clients to provide the connection using the most efficient available set of resources. Typically a server and client would indicate their respective support of this connection migration feature when the connection is established. An operating system or application program would monitor existing connections for characteristics including basic functionality and performance. If an existing connection were found to be faulty or low performing and the client and sever associated with the connection supported connection migration, the software would then determine if an alternative and more effective connection existed. Upon discovering such a connection, the parameters that define the connection would be altered to migrate the connection to the preferred hardware. In an embodiment in which the network connections are established with a transmission control protocol (TCP), each connection includes a four-tuple that completely defines the connection, namely, a source IP address, a source port number, a destination IP address, and a destination port number. By altering one or more of the connection's defining four-tuple, the invention is configured to migrate the connection to a NIC or system that is functioning more efficiently.

Title: Electrical power system for vehicles requiring electrical power while the vehicle engine is not in operation
Inventor: PLUMMER LEW
IPC: H02M1/00
Filed: 2005-07-26
Abstract: A system for supplying electrical power for use when the vehicle engine is shut down and configurations of long-haul trucks employing the system are disclosed. The power system is a battery bank contained within an insulated enclosure. The batteries are heated when the truck is in operation with the insulated enclosure maintaining battery temperature sufficient to provide high battery power capacity for an extended period after the vehicle is shut down. A large capacitor, rather than the batteries, provides current for starting the vehicle engine. A dc-to-do converter controls the fully charged capacitor voltage and provides capacitor charging current even when the batteries have been discharged to a low-voltage condition. The disclosed long-haul truck configurations include a storage cooler that employs a phase-change medium that is thermally charged to a low temperature while the truck is in operation and is used to provide sleeper unit cooling air. Additional provision is made for heating the sleeper unit and for powering a coolant heater that can warm the truck engine block and truck fuel when the engine is shut down during cold weather.
