摘要： Image shortening in a photolithographic process is substantially reduced by using sub-resolution reticle features to alter the aerial image in the shortened regions. The use of such sub-resolution reticle features is simple to implement in a design system, and allows for increased feature aspect ratio as well as overlap to other critical features.

摘要： A radio-frequency identification (RFID) transponder (tag) in accordance with the principles of the invention includes a patch antenna. The patch antenna may be co-located with RFID circuitry and an impedance matching circuit on one side of a substrate. A ground plane may be formed on the opposite side of the substrate. A quarter wave transformer may provide an “RF short” to ground to connect the RFID circuitry on one side of the substrate with a ground plane located on the opposite side of the substrate.

摘要： In a virtual reality system (20) an operator perceives being in a virtual reality world (74) of virtual reality images (62). The system (20) models the relative position and movement of objects (208 and 210) in a virtual reality world (74) by representing graphically a first (208) and second (210) object in a virtual reality world (74) on a graphical display (60 and 68). The representation selective obscures the first (208) and second (210) objects according to the relative position of the objects (208 and 210) to a predetermined observation point in the virtual reality world (74). The system (20) then determines a first partitioning plane (204) between the first (208) and second (210) objects. Then, the system (20) method determines a second partition plane (206) between the first (208) and second (210) object in response to either of said first (208) or second (210) objects moving across the first partitioning plane (204). Then, the system (20) graphically represent on the graphical display (60 and 68) the first (208) and second (210) objects within the virtual reality world (74) by selectively obscuring the first (208) and second (210) objects according to their relative position to the predetermined observation point.

摘要： A flat shower is a drainage fitting for the evacuation of surface and weeping water arising from showering on a tiled surface, where the tiling installation method is thinset, that is, where the tiles are adhered directly to membrane placed on top of a sloping medium such as mortar or foam installed directly to the subfloor. The height of such tile installations being minimal, a novel, minimal height flat drain assembly comprised of angle bar at the shower wall or flat bar in the midst of the flat tile floor, and said bar(s) then made contiguous with a floor drain membrane, is described.

摘要： A thinset floor drain comprises a saucer shaped mounting flange with a central lowermost circular perforated receptacle, and a perforated cup of smaller diameter that sits in the receptacle. The cup bears upward features including a grate support that threads into the inner thread of the cup, a grate that sits atop the upmost flange of the grate support, and grate tilting mechanisms. This structure serves not only as a flanged floor drain to drain surface water through the cylindrical core of the drain, it binds to a membrane beneath tiling and collects weeping water. The horizontal, vertical, and tilt adjustability of the upmost grate provide a safe grate surface that aligns with and is coplanar with the tile surface surrounding it. Because the receptacle sits below the subfloor, the grate will present a low profile above the surface of the subfloor.

摘要： A clicker ratchet limiter is a mechanical device that allows one part to move a defined distance relative to another by means of a linkage moving around a closed circuit track with a minimum and maximum position, and by means of a captured spring to allow for propulsion of the linkage around the track. One part, the anchor, is fastened to an anchoring object, leaving the top part to move between a minimum and maximum displacement position. Switching between positions is effected by compressing an internal coil spring by pressing down on the top part. The linkage device is a ratchet but not robust to pulling of the top off of the anchored anchor part. A hook and step displacement limiter is provided within each raceway pair of rib and inverted rib on the anchor and top part, respectively, to prevent pulling off of the top.

摘要： A splash-proof lavatory drain consists of a top, a tailpiece tube, and a flanged threaded pipe penetrating a drain hole in a vessel interior, wherein the flange engages the rim of the drain hole and is tightened by a nut and seals against the underside of the vessel. The top is a laterally perforated tube surmounted with a dome. The tube portion of the top inserts into the upper interior of a central perforation of the flange such that the dome prevents splash back from the drain interior and the rectangular perforations allow for drainage. This top is attached to the flanged threaded pipe by a range of means including a thread mate or a press fit. Drainage flow is increased by notching the lower edge of each perforation. Drainage flow is increased by notching the bottom of the perforations either partly or fully to the bottom of the top tube.

摘要： A nut and bolt fastens two perforated flat plates by threading fully into a nut on the opposing side of the plates. A threaded post, emanating from a flat, threaded into a complementarily threaded post hole cannot be equipped with strengthening features such as chamfers, fillets, or ribs because these devices block the strengthened threaded post from being fully threaded through perforated plates into a threaded posthole. The negative rib is a concavity spanning the orthogonal join between the post and the flat from which it emanates, and provides the same benefits that a regular rib provides, including discontinuity of join between post and flat, a variable distribution of forces amongst a more complex boundary area between post and flat, and the ability to increase the number, width, and depth of negative rib to achieve design objectives. The negative rib can also be decorated with fillets further strengthening the post against dehiscion from the flat to which it is attached.

摘要： A flanged pipe is mounted to a perforated fixed plate by limiting movement of the pipe in three mutually perpendicular axes, and rotationally around the plate axis. The mount consists of a plate and a flanged pipe. The pipe exterior is decorated with ribs parallel to the pipe axis. Each rib bears a microclip positioned to allow the plate to rest between the pipe rib microclips and the underside of the pipe flange. The perimeter of the plate perforation bears cutaways. Inserting the pipe through the perforation of the fixed plate engages the ribs with the cutaways to limit rotational movement. Movement in the plane perpendicular to the plate axis is limited by complementary diameters of the plate perforation and the pipe. Engagement of the flange on the plate limits movement of the flanged pipe through the plate perforation. Pipe retraction is limited by microclips.

摘要： A remotely actuated drain is provided by a bihemispherically sealed rod actuator restricted by a cat's eye restrictor to move in a vertical direction. This rod in turn actuates a plunger to move vertically to open the drain, the vertical motion of the plunger ensured by a central tubular guide up which the plunger stalk rod travels. The central guide is supported in the center of the drain by a threaded basket threaded into an internal thread provided in the top portion of the drain body to provide a removable anchor for the central guide. This cat's eye restricted actuator with a bihemispherical seal actuating a plunger guided by a removable threaded basket guide can be sized and fitted to a variety of vessels, including lavatory sinks, baths, and utility sinks.
