    Abstract: An electrical cord having improved safety features comprises a plug having a body portion surrounding respective ends of first, second, and third electrical wires. A live receptacle is in electrical communication with the end of the first electrical wire. A neutral receptacle is in electrical communication with the end of the second electrical wire. A ground receptacle is in electrical communication with the end of the third electrical wire. The body portion surrounds and maintains the live, neutral, and ground receptacles in spaced apart orientation corresponding to blades on an electrical plug. An indicator is provided to indicate a state of the plug in which electricity is supplied to the plug in a proper polarity.

    Abstract: A transfer ring of the type having a plurality of shoes arranged in a substantially circular configuration to define an inwardly-facing segmented cylindrical gripping surface, and a shoe for use in such a transfer ring, are disclosed. Each shoe comprises an arcuate interior surface defining a segment of the cylindrical gripping surface. The interior surface of each shoe has a first arcuate edge and an opposite second arcuate edge arranged substantially parallel to one another, and opposite first and second end edges extending between respective ends of said first and second arcuate edges. Each first end edge of each arcuate surface is mounted adjacent the second end edge of an adjacent arcuate surface, and the first end edge of at least one of the arcuate surfaces defines a varied or irregular shape along its arcuate surface.

    Abstract: A connector or adhesive assembly for joining adjacent ends of insulation tubing, comprising a layer of pressure-sensitive transfer adhesive material, said layer of pressure-sensitive transfer adhesive material capable of bonding to insulation tubing, whereby when said layer of pressure-sensitive transfer adhesive material is positioned between a first section of insulation tubing and a second section of insulation tubing, said layer of pressure-sensitive transfer adhesive material bonds to both the first section of insulation tubing and the second section of insulation tubing; and a disposable release liner member adapted to hold said layer of pressure-sensitive transfer adhesive material prior to positioning said layer of pressure-sensitive transfer adhesive material between the first section of insulation tubing and the second section of insulation tubing. Generally, the seam created when the first section of insulation tubing and the second section of insulation tubing are joined is covered with tape.

    Abstract: A system adapted for supporting workflow in a three-dimensional space which provides, among other things, hands-free control and adjustment of lighting within the three-dimensional space. The system of the present invention is also adapted for delivering, tracking, and retrieving tools in the three-dimensional space. The system of the present invention includes various subsystems, which are referred to herein as modules, that both act independently and co-dependently, as will be described in greater detail below, in conjunction with a central control computer module. The modules consist, in an exemplary embodiment, of the cable robot module, the central computer module, the imaging module, the illumination module, and the object manipulator module.
