摘要:
A system (100, 600, 700) for fastening objects to a wall or ceiling (120) comprises a rear, wall-anchor section (105, 607, 705) with a bore, and a front, pivotable section (110, 602, 604, 720), rigidly abutted together with no gap, aligned by a projection (135), and connected by a “living” hinge, strap, flap, lanyard or other type of connector (115). The pivotable section has a sharpened tip (112, 630, 635, 725) for penetrating the wall while the fastener is forced into the wall by a hammer or other driving tool or device, or manually by hand. The two sections of the fastener have a tapered, elliptical cross-section (111) which both prevents rotation of the fastener and locally reduces load-responsive pressure in the wallboard. To install, the axes of the wall-anchor and pivotable sections of the fastener are first aligned. The fastener is forced into the wall one of the above means. Then a pin (140) is manually inserted into the bore of the wall-anchor section. When the pin meets the projection the pivotable section is forced to rotate about the hinge. A locking tooth (139) secures the pin by interfering with either threads or notches in the pin. Alternatively, the pin forces past the projection and wedges between the projection and the bore of the wall-anchor section.

A wall and ceiling fastening system and method useful for applications such as hanging or securing objects to hollow walls and ceilings is provided. In one embodiment, the fastening system includes a drivable anchor having at least one pivotable section and a pin configured to be inserted into a channel of the anchor. The anchor is driven into a wallboard of the wall or ceiling with a hammer or a suitable tool. As the pin is inserted into the anchor, a lever or rack and pinion action between the pin and the pivotable section causes the pivotable section to pivot towards and come into contact with an interior surface of the wallboard. Depending on the fastening application, the pin can have a suitable head such as a pan screw head, a flat screw head, a round screw head, an oval screw head, a countersunk screw head, a machine screw head, a hook head, an eye hook head, a ring head, a swivel head, a shoulder head, a nut, a bolt head or other suitable head. In addition, the pin can have a ratcheted body, a threaded body, or a ribbed body. In some embodiments, the cross-sectional profile of the anchor is elongated so as to provide a larger supporting surface between the anchor and the wallboard. In addition, the cross-sectional profile of the anchor channel can be elongated so that a wider range of pin body sizes and types can be accommodated. The anchor body may also have one of more stabilizing ribs.

A wireless headset capable of receiving audio signals transmitted wirelessly and compatible for use in an MRI scanner is disclosed. The headset includes a first wireless module connected to the first earphone and a second wireless module connected to the second earphone. Each wireless module is electrically connected to a speaker in the respective earphone. The first wireless module receives the audio signal from a remote source and coordinates transmission of the audio signal to each of the speakers. The compact nature of each earphone minimizes the length of wire runs. In addition, the headset is made of materials having low magnetic susceptibility such that they will not be affected by the magnetic field from the MRI scanner.

An apparatus for generating electricity from a flowing stream of water is disclosed. A rigid frame is fixed with a pair of wheels, or with two linkages in circuit around two pairs of wheels. A plurality of blades are fixed between the wheel or linkages at their side edges, a cross-sectional area of each blade being substantially comparable to the cross-sectional area of the stream of water. An orientating mechanism is adapted to maintain the orientation of each blade such that rotation of the wheels or linkages results in an opposite rotation of each blade to maintain the orientation of the blade. As such, each blade “stabs” orthogonally into and out of the flow of water edge first, minimizing the displacement and disruption of the water upon entering. Each wheel or linkage, when mechanically coupled with a generator, results in the production of electricity.

A method is provided for measuring edge exclusion on a workpiece that includes a wafer having a film disposed thereon. The method is performed by a CMP system employing a platen and a thickness sensor coupled to the platen and positioned to repeatedly travel a path over the edge of the film during polishing. The method comprises measuring the thickness of the workpiece during selected iterations of the probe path, and establishing from the wafer thickness measurements the length of time the probe is over the film (ton) during the selected iterations. Edge exclusion is determined for at least one iteration utilizing a function related to ton.

A stent may be formed of at least one structural material having a pattern including at least one serpentine structure, which extends about the longitudinal axis of the stent. The structure is formed of a plurality of struts. Adjacent struts are interconnected by end portions having inner turns and outer turns. At least some of the end portions are elongated and other end portions are non-elongated and have a predetermined length. At least one of said elongated end portions is configured to serve as a fiducial marker.

The structure is formed of a plurality of struts. Adjacent struts are interconnected by end portions having inner turns and outer turns. At least some of the end portions are elongated and other end portions are non-elongated and have a predetermined length. The inner turns of the elongated end portions are substantially unaligned longitudinally with the inner turns of the non-elongated end portions. At least one of said elongated end portions is configured to serve as a fiducial marker.

A method of fabricating a film for attachment of one or more printhead integrated circuits to an ink supply manifold is provided. The method comprises the steps of: (a) providing an adhesive polymeric film having a protective liner; (b) depositing photoresist onto the protective liner; (c) photopatterning the photoresist to define a plurality of openings positioned for etching supply holes through the film; (d) etching the plurality of ink supply holes through the film, the photoresist acting as a mask for the etch; and (e) removing the protective liner having the photoresist deposited thereon.
