Title: Methods of forming power semiconductor devices using boule-grown silicon carbide drift layers and power semiconductor devices formed thereby
Inventor: TSVETKOV VALERI FEDOROVICH
IPC: C30B29/36
Filed: 2004-09-29
Abstract: Methods of forming high voltage silicon carbide power devices utilize high purity silicon carbide drift layers that are derived from high purity silicon carbide wafer material, instead of prohibitively costly epitaxially grown silicon carbide layers. The methods include forming both minority carrier and majority carrier power devices that can support greater than 10kV blocking voltages, using drift layers having thicknesses greater than about 100um. The drift layers are formed as boule-grown silicon carbide drift layers having a net n-type dopant concentration therein that is less than about 2x1015 cm-3.  These n-type dopant concentrations can be achieved using neutron transmutation doping (NTD) techniques.

Title: System and method for determining atomization characteristics of spray liquids
Inventor: GILES D KENNETH
IPC: G01N11/08
Filed: 2006-04-12
Abstract: A system and method for determining the atomization characteristics of fluids being emitted by a nozzle is disclosed. In one embodiment, a fluid is emitted through a nozzle while simultaneously sensing vibrations occurring within the nozzle. The vibrations provide information about the atomization characteristics of the fluid. By comparing the sensed vibrations to vibration patterns produced by known fluids through the same or a similar nozzle, the atomization characteristics of the fluid being tested can be predicted. In one embodiment, for instance, the atomization characteristics of a fluid may be determined as a function of velocity or flow rate through the nozzle.

Title: Rack-mounted door assembly
Inventor: LEVESQUE STEWART A
IPC: H04Q1/02
Filed: 2004-09-20
Abstract: Mechanisms for mounting, opening, closing and releasing a door assembly relative to a mounting structure are provided. The mechanisms employ a first structure that defines at least one elongated guide channel and a latching subassembly that is adapted to be mounted with respect to the foregoing guide channel(s) and to rotate with respect thereto. Rotation of the latching assembly with respect to the guide channel(s) allows a latching region, e.g., a V shaped latching region, to move between a first position (wherein the latching region is adapted to receive a mounting structure) and a second position (wherein the latching region cannot receive a mounting structure). In the second position, the latching region (in combination with the guide channel) is structured to capture a mounting structure (e.g., a projection associated with a cable management system) therewithin. Methods for use of the door assembly and latching subassembly are provided, as well as particular utilities thereof, e.g., rack-mounting applications.

Abstract: The established dogma for meningococcus is thus that immunisation against serogroups A, C, W135 and Y shall be based on the four different capsular saccharides, and that immunisation against serogroup B shall not be based on the capsular saccharide. In contrast, the invention uses polypeptide antigens and/or OMVs to immunise against serogroups A, C, W135 and Y (and against serogroup Y in particular). Serogroup B polypeptides can achieve this protection, thus permitting a single polypeptide-based vaccine to be used for protecting against all of serogroups A, B, C, W 135 and Y.

Filed: 2003-08-28
Abstract: Methods of processing seismic data to remove unwanted noise from meaningful reflection signals are provided for. The seismic data is transformed from the offset-time domain to the time-slowness domain using a Radon transformation. Preferably, the Radon transformation is applied within defined slowness limits p min and p max, where p min is a predetermined minimum slowness and p max is a predetermined maximum slowness, and an offset weighting factor x n is applied to the amplitude data, wherein 0 < n < 1. A high resolution Radon transformation preferably is used, where the transformation is performed according to an index j of the slowness set and a sampling variable .DELTA.p; wherein (see formula I) .DELTA.p is from about 0.5 to about 4.0 µsec/m, p max is a predetermined maximum slowness, and p min is a predetermined minimum slowness. A high-low, preferably a time variant, high low corrective filter is then applied to enhance the primary reflection signal content of the data and to eliminate unwanted noise events. The tau-P filter is defined by reference to the velocity function of the primary reflection signals, and preferably is expressed as: (see formula II) where r1 and r2 are percentages expressed as decimals. The slowness limits typically are set within ~ 15% of the velocity function, and r1 and r2 may be set accordingly.   After filtering, the enhanced signal content is inverse transformed from the time-slowness domain back to the offset-time domain using an inverse Radon transformation.
