Abstract: A vertical gallium nitride (GaN) PN diode uses epitaxial growth of a thick drift region with a very low carrier concentration and a carefully designed multi-zone junction termination extension to achieve high voltage blocking and high-power efficiency. An exemplary large area (1 mm2) diode had a forward pulsed current of 3.5 A, an 8.3 m?-cm2 specific on-resistance, and a 5.3 kV reverse breakdown. A smaller area diode (0.063 mm2) was capable of 6.4 kV breakdown with a specific on-resistance of 10.2 m?-cm2, when accounting for current spreading through the drift region at a 45° angle.

Abstract: The present invention provides systems and methods for monitoring a heart. According to one embodiment, the system includes an implantable registering unit for registering an electrical signal from the heart. The system includes a local data unit in operable communication with registering unit. The local data unit may be placed in communication with a computer, which may be at a location remote from the local data unit. The computer is adapted to receive the data from the local data unit corresponding to the registered electrical signal and to compare the registered electrical signal to a reference electrical signal to determine whether the heart is functioning properly.

Abstract: The disclosure generally relates to a looped pile film roll core used for winding a polymeric film, a method of winding film on the looped pile film roll core, and a roll of film that includes the looped pile film roll core. The disclosure describes an article and a process to reduce the core impressions created by the starting end of a web on the adjacent web layers next to the core. In one particular embodiment, the present disclosure can lead to a reduction in the amount and severity of such core impressions on a wound polymeric film, by reducing the amount of stress in adjacent layers of wound web.

Abstract: The present disclosure provides a process for producing low density polyethylene with a dissipation factor less than or equal to 1.48×10?4 radian at 2.47 GHz. The process includes free radical high pressure polymerization of ethylene and separation of the unreacted species from the resultant polyethylene to form a recycle stream. The process further includes purging dissipative components from the recycle stream. The purged recycle stream is then introduced into the polymerization reactor.
