| 20100099537 | CONTROL SYSTEM FOR DUAL CLUTCH TRANSMISSION - The present invention provides a control system for a dual clutch automatic transmission having a torque converter. The transmission provides seven forward speeds or gear ratios and reverse. The control system includes a hydraulic pump, a pressure regulator assembly and control valves that provide and release pressurized hydraulic fluid to the torque converter, a pair of input clutches and eight synchronizer clutches. A first pair of control valves are high flow rate valves which are capable of rapidly engaging and disengaging the input clutches. A second pair of high flow rate valves, control valves and spool valves provide a branching control circuit which controls engagement and disengagement of the synchronizer clutches. A control valve linked to the shift lever blocks hydraulic fluid flow to the first pair of high flow rate valves to inhibit input clutch activation when the shift lever is in Park or Neutral. | 04-22-2010 |

| 20090054206 | TORQUE CONVERTER - A torque converter having a lockup clutch or a coupling device, for selectively providing a mechanical connection between a drive unit and a drive train. The lockup clutch (C) or coupling device has a driving part connected to the drive unit and a driven part connected to the drive train.

| 20080213855 | Planar electroporation apparatus and method - An electroporation apparatus provides for the electroporation of adherent cells attached to an electrode surface or suspended cells in close proximity to an electrode surface. In one embodiment, the electrodes are transparent to allow cell viewing using a microscope or an automated image analysis machine. The geometry of the electrodes and associated electrically non-conductive structures may provide for well-defined regions of electroporated and non-electroporated adherent cells with a clearly defined interface between these regions, facilitating comparison of electroporated cells and non-electroporated cells, and evaluation of transfer of material from cell to cell via intercellular gap junctions. | 09-04-2008 |

The forming method and apparatus as well as the preform assembly include a hydrostatic pressing medium, such as a layer of glass, disposed within the die cavity proximate to at least one side of the workpiece. The hydrostatic pressing medium is configured to have a relatively low viscosity at the temperatures at which the workpiece is processed, thereby facilitating the relatively even application of pressure to the workpiece. As such, a workpiece having a complex configuration may be formed utilizing a single acting die. | 01-28-2010 |
| 20110135418 | SELF EXPANDING FASTENER - In one embodiment a method to join a first structure to a second structure, comprises aligning a first hole in the first structure with a second hole in the second structure and inserting a fastener into the first hole and the second hole. The fastener comprises a shape memory alloy which was formed into a first shape having a diameter slightly larger than a diameter of the first hole and the second hole when the shape memory alloy was in an austenite state and reduced to a second shape having a diameter less than the diameter of the first hole and the second hole when the shape memory alloy was in a martensite state. The method further comprises heating the fastener above an austenite start transition temperature, such that the fastener initiates free expansion from the second shape back to the first shape and establishes physical contact with the surface of the first hole and the second hole and continuing to heat the fastener such that first structure and the second structure proximate the holes and the fastener undergo plastic deformation. | 06-09-2011 |

| 20100228873 | Protocol Agnostic Request Response Pattern - A system and method for facilitating communications over a protocol is provided. The system includes a class factory that holds identifiers associated with determining which, if any, registered protocol object creator should be employed to create a protocol object. The protocol object implements an abstract network protocol base class.

| 20090259264 | SURGICALLY IMPLANTABLE WIRE CONNECTOR - A surgically implantable wire connecting device that is adaptable to accept various diameter wires by selecting pre-wired mandrels, each having a specific candidate diameter wire and length, and attaching the mandrels together in a metal crimp tube. The final assembly during surgery requires a simple crimp of the crimp tube to the adapter tube by using a standard crimp tool. The delicate lead wires that are being attached are not deformed or crushed by the crimp process and are located remote from the crimp. | 10-15-2009 |
