Abstract: A coving installation device includes a unitary structure having a first magnetic face, a second magnetic face, and a third magnetic face. The second face is joined with the first face by an arced side. The third face is joined with the second face by a linear side. The third face is joined with the first face by an angled side. The second face is perpendicular to the first face and the third face is perpendicular to the second face. The first, second, and third faces protrude from the arced, linear, and angled sides. A clean room installer using the coving installation device can independently install coving without assistance.

Abstract: A system for simulating a hysteroscopy procedure is disclosed. The system includes a base station adapted to communicate with a computer having a display monitor.

Abstract: two blocks of structural foam are fitted with shoe buckles. The blocks have ground contacting areas larger than the user's shoes for stability, and to reduce the toss-over effects of stepping on construction junk on the floor. Small objects embed in the resilient surface of the foot so their effect on walking and stability are nullified.

Abstract: A roof batten integrally-formed of plastic with spaced, generally parallel upper and lower surfaces and a series of struts connecting the upper and lower surfaces, to form chambers permitting the fluid passage from the back edge to the front edge of the batten when it is affixed generally horizontally along a roof surface.

Abstract: Phase shifting plasma electromagnetic waveguides and plasma electromagnetic coaxial waveguides, as well as plasma waveguide horn antennas, each of which can be reconfigurable, durable, stealth, and flexible are disclosed. Optionally, an energy modifying medium to reconfigure the waveguide such that electromagnetic waves of various wavelengths or speeds can be propagated directionally along the path can be used. Similarly, these waveguides may be modified into coaxial configurations.

Abstract: The present invention is drawn toward plasma electromagnetic waveguides and plasma electromagnetic coaxial waveguides that are reconfigurable, durable, stealth, and flexible. Specifically, the present invention discloses and describes a reconfigurable electromagnetic waveguide comprised of a) an elongated non-conductive enclosure defining a propagation path for directional electromagnetic wave propagation; b) a composition contained within the enclosure capable of forming a plasma, said plasma having a skin depth along a surface within the enclosure such that the electromagnetic waves penetrate the skin depth and are primarily propagated directionally along the path; and c) an energy source to form the plasma. Optionally, an energy modifying medium to reconfigure the waveguide such that electromagnetic waves of various wavelengths may be propagated directionally along the path may be used. Similarly, these waveguides may be modified into coaxial configurations.

Abstract: An expandible antenna device comprising an expandible shell defining an interior chamber, wherein the shell is radially expandible from a central axis within the chamber; an elongated support structure disposed along the central axis and at least partially within the chamber; and an antenna element coupled to the shell such that the antenna is dimensionally stable when the shell is in an expanded position is disclosed. Additionally, an antenna element comprised of conductive elements joined by fluid filled bulbs or tubes wherein the fluid is capable of ionization is also disclosed.
