  • Patent number: 10211328
    Abstract: A normally-off, heterojunction field effect transistor includes an intrinsic cubic-phase gallium nitride (c-GaN) substrate and an aluminum gallium nitride (AlGaN) capping layer disposed on the intrinsic c-GaN substrate. The AlGaN capping layer includes a first sublayer of intrinsic c-phase AlxGa1-xN disposed on the c-GaN substrate, wherein the first sublayer is of a first thickness; a second sublayer of doped c-phase AlxGa1-xN disposed on the first sublayer, and wherein the second sublayer is of a second thickness and is doped with a dopant. An insulating layer is disposed on the AlGaN capping layer, wherein the insulating layer is of a fourth thickness. A source electrode, a drain electrode, and a gate electrode are positioned adjacent to and on top of the insulating layer, respectively.

  • Publication number: 20140206855
    Abstract: Methods are provided for detection of cancers associated with methylation of hMLH1 promoter DNA in a subject. The method comprise assaying for the presence of methylated hMLH1 promoter DNA in a bodily fluid from a subject. In one embodiment, the method comprises reacting DNA from the sample with a chemical compound that converts non-methylated cytosine bases but not methylated cytosine bases, to a different nucleotide base. The compound-converted DNA is then amplified using a methylation-sensitive polymerase chain reaction (MSP) employing primers that amplify the compound-converted DNA template. The present invention also provides nucleotide primer sequences for use in the methylation-sensitive PCR assay.

  • Patent number: 8695861
    Abstract: A stitching head is provided having a cam connected to the bender rail rail, the cam operates to redirect the staple driving force being applied by the driver rail to the driver and upon the staple during the staple driving step of stitching head operation; the force-redirecting position of the cam is automatically adjusted in response to the thickness of each workpiece as the cam is connected to the bender rail rail and the contacting of the workpiece by the bender rail repositions the cam at the desired distance above the workpiece to reestablish the set-point for the redirection of the staple driving force being applied to the driver rail upon as staple head contacts each variable thickness workpiece.

  • Patent number: 8485425
    Abstract: Each respective mail item in a received batch of items is read to acquire information, which enables a plurality of verifications with regard to authenticity of the respective mail item. In a vote-by-mail example, one or more features are validated for authenticity in relation to the election, and one or more features are validated for authenticity in relation to a voter. The verifications in relation to a voter may involve detection of a signature and verification of the authenticity of the signature. The items are sorted according to the verification results and may be sorted based on other criteria. The methods, systems and software disclosed herein enable such verifications and sorting, in a single pass through a sorting system.

  • Publication number: 20070185461
    Abstract: A medical device for use with a fluid transfer device includes a hub having an open proximal end with a frusto-conically-shaped cavity therein, a distal end and a passageway therethrough. The cavity is part of the passageway. A release element in the passageway of the hub is positioned to block fluid-tight engagement of the frusto-conically-shaped tip with the cavity of the hub. Structure is provided to release at least part of the release element, upon application of a proximally directed force on the hub, to allow the abrupt fluid-tight engagement of the tip and the cavity in the hub.
