Abstract: A dental tool for guiding a drill bit during a dental implant procedure includes a pivotal drill bushing attached to a bushing holder. The bushing holder, in turn, is attached to a surgical dental stent that fits a patient's jaw. The bushing holder attaches to the stent by extending into a hole or bore of the stent. In some cases, the bushing holder snaps into the hole.

Abstract: A dental tool for guiding a drill bit during a dental implant procedure includes a drill bushing that is pivotally attached to a stent, wherein the drill bushing has a generally spherical surface that directly engages the stent.

Abstract: A dental tool for guiding a drill or biopsy punch during a dental implant procedure includes a drill bushing pivotally attached to a bushing holder. The bushing holder, in turn, is attached to a surgical stent that fits a patient's teeth, gums, and/or jaw. The pivotal connection between the drill bushing and the bushing holder allows the angular orientation of the drill bushing to be adjusted, so the trajectory of the drill or biopsy punch can be aimed directly into the patient's jawbone. Once the drill bushing is properly oriented, the bushing is bonded to the bushing holder to prevent further movement between the bushing and the holder.

Abstract: A method for a dental implant process involves creating an overall image that shows a trajectory of a drill bushing in relation to a patient's jaw. The overall image shows a trajectory image that represents the trajectory of the drill bushing and a jaw image that represents the jaw. The method allows a user to move the trajectory image relative to the jaw image, which can be useful when adjusting the angular position of the actual drill bushing.

Abstract: A flexible guide for a door includes straps that are mounted in pairs along either side of a doorway. The straps for each pair are generally parallel, facing each other, and spaced apart to create a gap or channel between the two. As the door opens and closes, the straps guide the vertical movement of a door panel that travels within the channel. The straps are pulled in tension between upper and lower anchors to provide the straps with enough stiffness to effectively hold the door panel within the channel under normal operation. In some embodiments, springs are used to maintain the tension in the straps. The straps are also sufficiently pliable and resilient to allow an impact to dislodge the door panel out from within the channel without damage. The upper or lower anchor is moveable between a normally extended position and a yielded position to prevent an impact from breaking the anchor and may further be biased to the normal position.

Abstract: A cable tensioner for an industrial door helps keep a cable neatly wrapped on its take-up drum. In some embodiments, the tensioner functions in a first mode during normal door operation, and operates in a second mode when the tension in the cable decreases to a predetermined low level. When operating in the second mode, the tensioner is able to take up slack in a cable that supports a door member, such as a door panel or a deadweight that counteracts the door panel's weight. The tensioner may be adapted for use on various doors including, but not limited to, sectional doors, roll-up doors, high-lift doors, horizontally storing doors, vertically storing doors, and various combinations thereof.

Abstract: A restraint for a parked swap body container includes a face stop that can be selectively positioned to a restraining position and a release position. In the restraining position, the face stop is adapted to engage a front face of the container to limit the extent to which the parked container can move away from an edge of a truck loading dock. In The release position, the face stop allows a truck to remove the container from the loading dock. The restraint may also include a frame that can be repositioned longitudinally to accommodate containers of various lengths. A fine adjustment can be added to further limit horizontal movement of the container. And an optional bottom support could engage the bottom of the container to provide even more support.

Abstract: A pulling-style restraint for a swap body container parked at a truck loading dock includes an elongated member having a base at one end and a restraining member at an opposite end. The base can be attached to the dock, while the restraining member is adapted to be connected to a leg or bottom fitting of the container. The elongated member can be a bar or an elongated pliable member such as a strap, chain, or cable. The elongated member can be tightened by a take-up device such as a reel, chain-binder, turnbuckle or combinations thereof. Additional features might include a light that indicates engagement, a twist-lock restraining member, and a firm landing pad on which the container legs may rest.

Abstract: A repositionable brace helps support the legs of a swap body freight container parked at a truck loading dock. The brace can move from a retracted position to an engaged position. In the engaged position, one end of the brace is at least partially fixed relative to the dock with an opposite end engaging at least one of the container's four legs. In the retracted position, the brace is positioned to where it is more out of the way when not in use, or positioned to align the brace to legs at other various locations. In some cases, the brace pivots between the locked and retracted positions manually, hydraulically, electro-mechanically or pneumatically. Also, a firm landing pad can be associated with the brace to provide a more consistent, level height at which the swap body is parked.

Abstract: A jaw model articulator clearly identifies condyle joint strain as well as fully emulates a patient's straight bite and cross bite. The spatial relationship of the upper and lower jaws with respect to the condyle joints and to each other is accurately determined by just two wax bite impressions taken of the patient. No extraneous mechanical hardware needs to be attached to the patient's head. The two wax impressions are sequentially inserted between the upper and lower jaw models. The resulting change in the models relative positions are measured and the values inputted to a desk top personal computer. The computer calculates the precise location of the rotational axis defined by the condyle joints, and the articulator is set up accordingly.
