A cutting element for a drill bit includes an outer support element and an inner rotatable cutting element, a portion of which is disposed in the outer support element, where the inner rotatable cutting element has a body with a non-planar cutting face.

A metal anchoring fastener fastens millwork onto walls constructed with wall cladding fastened to steel studs. The load typical of a loaded cabinet is borne by the steel stud anchors owing to the mate between the profile of the steel stud anchor and the layers of millwork and wall cladding and steel stud that said anchor penetrates. The pitch of the thread adorning the profile of the steel stud anchor progresses non-linearly along the length of said shaft, the shaft is generally non-linear in profile, and the thread profile is non-uniform along the length of said shaft. The anchor can also support a secondary screw concentrically penetrating the void at the center of the anchor, in order to hang loads from a wall, with or without millwork. Predrilling of the holes can enable installation of these zinc anchors.

A device for the automatic manufacture of screw connections by a screw includes a motion system with which the screw can be led to the components to be connected. The screw is taken up by an automatic screwing arranged on the motion system. A protective sleeve is arranged so that it can be moved with the automatic screwing unit. The protective sleeve acts as protection, surrounds the screw, and is arranged out of contact with one of the components to be connected.

A ventilated structural panel comprising a first sheet, having a long axis defining a length and a perpendicular short axis defining a width, a plurality of spacing structural elements, fixedly attached to the first sheet such that the yield strength of the panel is greater than the individual yield strength of the first sheet, and the plurality of spacing structural elements being formed such that a plurality of unobstructed pathways are created for air to move from at least one edge of the panel to at least one of an opposite and an adjacent edge of the panel, wherein the first sheet is the only sheet in the panel.

Methods to partially decrease reflectivities of at least two regions on a mirror platform relative to a reflectivity of a third region are taught. A first region is defined on a surface of the mirror platform. The first region is a media display device viewing area. A second region is defined on the surface of the mirror platform. The second region is a back lit area. A first material is selectively disposed onto a rear surface of the mirror platform outside of the first region and outside of the second region. The first material increases the reflectivity of the mirror platform outside of the first region and outside of the second region. When the mirror platform is viewed from a front side a reflectivity of a third region, which is outside of the first region and outside of the second region, is greater than a reflectivity of either the first region or the second region; and a reflectivity of the first region is different than a reflectivity of the second region.

According to some embodiments, systems and methods of ultrasonic detection of implantable medical device distraction are provided. The system includes a first elongate member and a second elongate member. The first elongate member has a first end that is configured to be attached to a first location on the skeletal system of a subject, a second end, and at least one landmark identifiable using ultrasound. The second elongate member has a first end that is movably coupled to the second end of the first elongate member, a second end configured to be attached to a second location on the skeletal system, and at least one landmark identifiable using ultrasound. Movement of the first elongate member in relation to the second elongate member causes a corresponding movement of the at least one first landmark in relation to the at least one second landmark which can be detected using ultrasound.

A self-drilling, self-tapping bone screw is described in which the bone screw has a drill tip free of threads and having a length at least as great as about the thickness of a proximal cortical bone layer, with the drill tip having opposed lands and a helical flute between each of the lands with each of the lands having a cutting edge configured to cut bone as the drill tip is rotated into the bone with the flutes conveying the bone debris away from the drill tip, where a lead thread begins to self-tap internal threads in the proximal cortical bone layer after the drill tip has drilled through the proximal cortical bone layer so as to avoid stripping the threads formed in the bone layer. A method of installation is also disclosed.

A microfilter having a hydrophilic surface and suited for size-based capture and analysis of cells, such as circulating cancer cells, from whole blood and other human fluids is disclosed. The filter material is photo-definable, allowing the formation of precision pores by UV lithography. Exemplary embodiments provide a device that combines a microfilter with 3D nanotopography in culture scaffolds that mimic the 3D in vivo environment to better facilitate growth of captured cells.

An installation tool fastener is particularly adapted for fastening a top plate to a roof support member and other structural connections and is particularly adapted for use with an installation tool. The installation tool fastener has a head with a maximum head diameter and a recess for coupling with a drive coupler. The shank of the head has an unthreaded portion and a uniform thread which has a major diameter approximately equal to the maximum diameter of the head. The head preferably has a slight taper. The thread preferably has a 7.5 thread per inch pitch and a thread angle from approximately 25 to 45. In one embodiment for a 6 inch fastener, the thread length is approximately 5 inches and extends along the tapered distal tip.

A method of constructing a building comprising the steps of attaching a first panel to a second panel. The first panel is one of a single plenum panel and a multi-plenum panel and the second panel is one of a single plenum panel and a multi-plenum panel.
