Abstract: In one aspect the plasma lamp according to the present invention comprises a gas envelope that is constructed from ceramic material and a sapphire window rather than quartz. According to another aspect of the present invention, a plasma lamp comprises an RF structure for the radio wave radiation and an envelope for housing the excitation gas that are formed so as to constitute a single, integrated ceramic structure. According to yet another aspect of the present invention, the plasma lamp comprises a waveguide structure having solid material such as ceramic rather than air for the dielectric and a gas housing made of a combination of solid ceramic and a sapphire window. In this way, the separate quartz gas envelope and air-filled waveguide structure employed in the prior art are replaced by a single, integrated structure.

Abstract: An aerosol deflecting dental shield and containment device having a cylindrical base with a lower free end and with a base sidewall having an inner surface enclosing and defining a base channel base channel defining a base channel diameter and with an HVE adapted to be inserted therein. The device also includes a circular base platform radially extending outwardly from the base channel, a deflecting member coupled to the circular base platform, with an outer surface opposing the lower free end, of an elastic polymeric material, defining an intake aperture fluidly coupled to the base channel, and defining a deflection diameter of a length at least twice a length of the base channel diameter, and a cantilevered tooth rest member projecting from the outer surface of the deflecting member, having a spherical apex disposed at a distal end thereon, and of an elastic polymeric material.

Abstract: A rear projection display system (RPDS) and associated optical system are described with a reduced field angle. The RPDS includes a screen and a housing. The optical system includes a light engine, a first mirror, a second mirror and a Fresnel lens arranged to achieve a thin housing. The light engine is generally disposed in an upper region of the housing, and projects light onto the first mirror, which can be located at a bottom portion of the housing. The first mirror reflects the projected light onto the second mirror, which in turns reflects the light towards the Fresnel lens, which transfers the light onto the screen. A total internal reflection Fresnel lens is used to reduce cost and complexity without sacrificing image quality and housing thinness. An image processing device can also be used to compensate for geometric and optical distortions in the final image displayed on the screen.

Abstract: An ultra-thin rear projection display system (RPDS) is disclosed. The system uses a small flat mirror, a small non-rotationally symmetric mirror and a larger non-rotationally symmetric mirror to achieve a D-to-d ratio of around 11:1 while rendering a significantly distortion free image on the screen. The first two mirrors are significantly smaller than the size of the screen, while the third mirror is significantly larger than the first two mirrors but smaller than the screen. In one embodiment, the lens and light engine are positioned horizontally to one side and, in another example, the lens and light engine are positioned vertically, projecting downwards. In one example, an image processor is used to correct for the remaining distortions. In another example, the system is adapted such that the light rays forming the projected image are within a certain range of angles such that a TIR Fresnel lens could be used to collimate the image.
