  • Patent number: 8820011
    Abstract: A stage floor assembly can be easily assembled, aligned and adjusted even on an uneven surface. The stage floor assembly includes a plurality of pedestals with each pedestal further comprising a pedestal base attached to a plurality of rods. There is a plurality of stringers placed upon some of the plurality of rods such that two stringers terminate at each pedestal and one stringer crosses two rods on each pedestal forming a grid network that self-aligns even on the uneven surface. A plurality of deck plates is attached to the plurality of stringers creating a surface to absorb and distribute loads across pedestals preventing noticeable deflection across the stage floor assembly.

  • Patent number: 8753819
    Abstract: Nucleic acid amplification assays for mutations to two short sections of the fungal gene FKS1. Mutations in these target sequences have been shown to correlate with resistance to echinocandin-class drugs. Assays may include detection by sequencing or by labeled hybridization probes. Also, primers, probes and reagent kits for performing such assays.

  • Publication number: 20110091872
    Abstract: Methods are provided for detecting triazole -resistant fungi in a sample. The methods comprise evaluating the sample for the presence of a gene encoding a mutant AzRF1 transcription factor, or the level of the transcription factor, to determine whether a fungus is triazole-resistant. Primers, probes and kits also are provided.

  • Publication number: 20100221710
    Abstract: Methods and kits are described for testing for the presence or absence of any fungus in a sample. Examples of fungi that can be detected include, but are not limited to, those belonging to the genera Candida, Aspergillus and Pneumocystis. The methods include obtaining a sample suspected of containing fungal nucleic acid, including at least one universal region of fungal nucleic acid, and testing for the presence or absence in the sample of the at least one universal region of fungal nucleic acid. Samples may be biological or non-biological.

  • Patent number: 7682918
    Abstract: A process for forming a vertical DMOS device with an ESD protection transistor that is configured for carrying a breakdown current includes the steps of masking a substrate of a first polarity type and forming spaced apart surface isolation regions. An insulated gate is formed between the spaced apart surface isolation regions. Selected portions of the surface regions between the gate and the surface isolation regions are heterodoped to form p-n junctions having retrograde doping profiles beneath the substrate surface thereby lowering the breakdown voltage beneath the heterodoped portions in order to direct a substantial portion of the breakdown current below the surface of the substrate and into the body of the substrate between the heterodoped regions. Source and drain regions are formed in the substrate surface on opposite sides of the gate.

  • Publication number: 20070028448
    Abstract: A hair trimming device includes a cutter and a handle member. The cutter is substantially rectangular and flat and includes a blade and a frame. The handle member includes a hollow interior containing the cutter while the cutter is not in use. The cutter in use is exposed out of the handle member and is mounted above the handle member to be in line with the handle member. The frame member is configured to form a first contact line with a skin and at least one edge of the blade is configured to form a second contact line with hair. The second contact line is more distal from the skin than the first contact line.

  • Patent number: 6873017
    Abstract: Device 60 in FIG. 3 has junctions 86 each with a lateral portion 90 and a second portion 92 extending upward toward the surface 12 from the lateral portion 90. The lateral portions 90, as illustrated in FIG. 3, are more or less formed along a plane parallel with the surface 12. The upwardly extending portions 92 include characteristic curved edges of the diffusion fronts which are associated with the planar process. With the regions 80 and 82 each having relatively high net dopant concentrations of different conductivity types, each lateral junction portion 90 includes a relatively large sub region 96 which extends more deeply into the layer 10. When compared to other portions of the junctions 86, the subregions 96 are characterized by a relatively low breakdown voltage so that ESD current is initially directed vertically rather than laterally.

  • Patent number: 6202762
    Abstract: An improved drilling assembly of the type comprising a fluid driven motor, a driveshaft operatively connected with the motor, a housing for enclosing the driveshaft and an annular flow passage defined between the driveshaft and the housing for circulating drive fluid therethrough. The improvement comprises a drive fluid flow restrictor device comprising a constricted section in the annular flow passage, an expanded section in the annular flow passage and a valve member positioned in the annular flow passage. The valve member is movable axially in the annular flow passage between the constricted section and the expanded section to define a flow restricting position and a normal flow position When the valve member is in the flow restricting position the circulation of drive fluid through the annular flow passage is restricted. When the valve member is in the normal flow position the circulation of drive fluid through the annular flow passage is relatively unrestricted.

  • Patent number: 6091146
    Abstract: A reworkable multi-chip module contains a large multi-chip module package (2) with an opening at the top to permit access to an internal region for semiconductor devices, the opening being at least four square inches area with the length or width dimension being at least two inches. The opening is sealed with a stiff closure (1) of sufficient rigidity to withstand at least one atmosphere of differential pressure without significant deflection, is removable in a single piece and may be reinstalled. The closure includes a panel of electrically non-conductive material (3) and a metal flange (5) borders the periphery of the panel to support the panel on the top of the module package.
