Abstract:
An ignition control device having an Electronic Fuel Injection (EFI) mode and a Capacitive Discharge ignition (CDI) mode is described. The ignition control device comprises: an output for providing an output voltage (V0UT), connected or connectable to a load, the load being a fuel injection actuator of an EFI system or an ignition capacitor of a CDI system; and a driver unit connected to the output, for driving the output voltage from a low level (V0UTI) to a high level (VOUTO) and from the high level to the low level in dependence on an input signal (On/Off), each transition of the output voltage from the low level to the high level having a low-to-high transition time which is longer for the CDI mode than for the EFI mode.
Abstract:
An insertion device for use in assisting with the placement of a medical device within the body of a patient is disclosed. For example, the insertion device can be employed to assist with the placement of an introducer, which provides a conduit for insertion of a catheter into the body. In one embodiment, the insertion device comprises a needle that is removably disposed within a bore defined by the medical device, and a needle retraction assembly. The needle retraction assembly can position the needle in any one of a first position wherein a distal tip of the needle is disposed a predetermined distance distal to a distal end of the medical device, a second position wherein the needle distal tip is disposed distal but proximate to the distal end of the medical device, and a third position wherein the needle distal tip is retracted within the medical device bore.
Abstract:
A stent or other prosthesis may be formed by coating a single continuous wire scaffold with a polymer coating. The polymer coating may consist of layers of electrospun polytetrafluoroethylene (PTFE). Electrospun PTFE of certain porosities may permit endothelial cell growth within the prosthesis. The stent may be applicable to stents designed for the central venous system, peripheral vascular stents, abdominal aortic aneurism stents, bronchial stents, esophageal stents, biliary stents, or any other stent.
Abstract:
A system for friction stir welding small diameter tubing, where the tubing is held in a correct position and can be rotated by the positioning and holding system while a FSW tool is held stationary, or vice versa. Internal mandrels are also described which can fit inside the smaller dimensions of the small diameter tubing and expand to provide a counter force to prevent deformation of the tubing when forces are applied by the FSW tool, A new FSW tool enables the FSW tool to direct more heat on a tool/workpiece interface to counteract a lack of contact between the FSW shoulder and the workpiece because of tube curvature. The FSW tool is positioned on a small diameter tube by trailing the joint to provide desirable heating at the joint/workpiece interface and surface finishing.

Abstract:
A connector assembly includes a shell having a mating interface and a cavity. A dielectric body is received in the cavity and includes a contact channel extending from a front end of the dielectric body to a rear end of the dielectric body. The dielectric body has a contact slot open along a rear portion of the contact channel, wherein an anvil section is defined at a forward intersection of the contact channel and the contact slot. A contact is received in the dielectric body and includes a mating end extending along a mating centerline and a mounting end extending along a mounting centerline that is transverse to the mating centerline. The contact has a transition section bent at a transition angle, wherein the contact is bent about the anvil section to the transition angle.
Abstract:
A connector assembly (100) includes a housing having a cavity (108) defined by at least one wall (170). The cavity extends between a mating end and a loading end. The housing has a terminal latch (190) associated with the cavity, and the at least one wall has a projection (180) extending into the cavity. A terminal (104) is loaded into the cavity (108) through the loading end and is held within the cavity by the terminal latch (190). The terminal (104) includes body having an opening (158), wherein the projection (180) extends at least partially into the opening (158) to secure the terminal (104) within the cavity (108).
Abstract:
The present invention provides an apparatus and method for occluding tributary blood vessels inside a principal blood vessel while still allowing blood to flow through the principal vessel. The apparatus has a support structure and associated membrane that can be collapsed for insertion into the principal vessel. Once inserted at the desired location the support is allowed to expand, forcing the membrane to contact the inner walls of the vessel with sufficient force to occlude the openings of the tributary vessels.
Abstract:
A radio frequency identification (RFID) tag circuit (120, 220) or RFID tag may be fabricated on a printed circuit board (PCB) (100) and/or on a printed circuit panel from which PCB's are made. In some embodiments the RFID tag may be created early in the fabrication process and become operational before the PCB has been finished.
Abstract:
A Superconducting Quantum Interference Device (SQUID) is disclosed comprising a pair of resistively shunted Josephson junctions connected in parallel within a superconducting loop and biased by an external direct current (dc) source. The SQUID comprises a semiconductor substrate and at least one superconducting layer. The metal layer(s) are separated by or covered with a semiconductor material layer having the properties of a conductor at room temperature and the properties of an insulator at operating temperatures (generally less than 100 Kelvins). The properties of the semiconductor material layer greatly reduces the risk of electrostatic discharge that can damage the device during normal handling of the device at room temperature, while still providing the insulating properties desired to allow normal functioning of the device at its operating temperature. A method of manufacturing the SQUID device is also disclosed.
