An internally threaded anchor for use in poured concrete floors having a metal deck or a wood form. The threaded anchor provides quick and easy attachment to threaded support rods that carry racks for utilities, piping, or ceiling grid systems. Each threaded anchor is capable of accepting different diameter rods or bolts with different thread cuts. Each anchor accepts the different diameter threaded rods by a single insertion motion, without the need to thread the rod into the anchor. Full insertion is visually verifiable when the marked end of the rod inserted into the anchor is no longer visible. An authentication tag visible upon full insertion indicates that authorized rod is being used.

Endotracheal intubation systems, methods, and kits are provided. The system may include an endotracheal tube assembly which includes an endotracheal tube having a proximal end and a distal end; a wire having a proximal end and a distal end, wherein the wire is configured to be removably inserted into the endotracheal tube through the proximal end of the endotracheal tube; an internal magnetic member fixed at the distal end of the wire; and an end cap attached to the proximal end of the wire and removably securable to the proximal end of the endotracheal tube, wherein at least a portion of the internal magnetic member is disposed within the distal end of the endotracheal tube at a fixed position when the end cap is secured to the proximal end of the endotracheal tube; and an external magnetic member positionable on the exterior of a patient.

A connector of frangible material for mounting on the piercing end of a nail-like fastener, connects the fastener to a bracket or clamp. The bracket has a conical frustrum-shaped aperture. The connector has a conical frustrum-shaped leading end that fits into the conical frustrum-shaped aperture in the bracket. The trailing end of the connector grips the fastener. The connector locks to the bracket by passing its trailing end through the leading opening of the conical frustrum-shaped aperture and snugging the conical frustrum leading end of the connector into the conical frustrum-shaped aperture in the bracket.

Poured concrete floors and ceilings in buildings contain electrical conduit, air conditioning conduit, plumbing and junction boxes, for example. These conduits must withstand the rigorous activity of a construction floor and the concrete poured on them during the construction phase. Rod support structures made out of steel rod stock are used to hold the conduit and junction boxes in place on a temporary plywood floor in between rebar. The support structures have feet. The poured concrete floor covers the conduit, junction boxes and support structures. The footprint of each of the support structures is designed to be as small as possible by having minimum contact with a temporary plywood floor. When the plywood floor is removed, the support structures are substantially buried in the concrete. The concrete floor is underneath the feet, providing minimum exposure of the feet to the surface of the concrete next to the plywood floor.

A method and system are provided for configuring a user interface to a user role. A user model defines one or more user roles and one or more tasks, each user role being linked to: one or more user tasks via one or more user goals, and a set of skills a user performing the role must have, wherein each task is also linked to one or more skills. A software product defines one or more software functions, and means are provided for linking each user task to a sequence of software function calls. The system includes an organization modeling tool including means for customizing the user model dynamically to alter the user role to task mapping to meet the current needs of an organization including validating the goals and sets of skills of the user model. The system also includes a display structure model including means for configuring a user interface to a user role, the display structure model being a runtime component for dynamically building control menus for groups of tasks depending on the user role of the logged on user.

A driver for securing pre-wired threaded fasteners to the ceiling of a building structure includes a driver head, a pre-wired fastener held by the driver head, and a telescoping pole connected to the driver head. The driver head is a solid, cylindrical rod or shaft having a kerf opening through the top of the shaft and extending axially therefrom, the kerf extending either partially or completely across the diameter of the shaft. The kerf includes a tapered recess opening axially through one sidewall of the shaft. A blind recess shaped to receive the flat head of a threaded fastener also opens through the top of the shaft and intersects the kerf substantially orthogonally. The threaded fastener is pre-wired with a wire which has a closed loop at one end, the loop being off-set from the major lineal direction of the wire. When the head of the threaded fastener is fit into the blind recess, the wrap of the wire is loosely constrained against lateral motion by the tapered recess. A hollow telescoping pole has at least one aperture in a sidewall, the aperture positioned such that the free end of the wire can be inserted into the hollow interiior of the pole to confine the free end against spinning around the pole when the pole is rotated.

This invention relates to an impact actuated tool for driving a fastener by an explosive charge, particularly a tool having a housing with a barrel axially slidably mounted within the front end. A nosepiece is fixed to the front of the barrel with a muzzle at its front end for receiving a fastening element that is to be secured in a ceiling or the like. A piston is slidably mounted within the bore in the barrel. The barrel is biased forwardly in the firing direction. At the rear of the tool a handle engages a firing pin which is slidably mounted within the rear end of the bore. The firing pin is biased rearwardly towards the back end of the tool. One embodiment of the tool includes a ball lock safety device to allow discharge only when the muzzle of the tool is pointed in an upward direction. The tool is fired by impacting the nosepiece against a surface to effect displacement of the barrel and firing pin against their respective biasing springs.

In a weapon boresighting system for aircraft and vehicles, an optical square is oriented to a fixed reference line on the vehicle and provides the directionality of a pair of orthogonally positioned of laser illuminated retroreflective catadioptric collimators attached to said optical square whose outputs are directed via one or more deviators or periscopes to a pair of retroreflective catadioptric receivers orthogonally attached to a second optical square positioned at the weapon to be boresighted, each said receiver imaging the laser on a position sensitive sensor, the outputs of the latter indicating the pitch roll and yaw condition at the weapon.
