Abstract: A digit cover for conveying a non-verbal message. The digit cover includes at least a first message area for conveying a first message. The digit cover may also include additional message areas for conveying additional messages.

Abstract: An improved vibration damping apparatus is provided for use with window structures, including windows used in vehicles, aircraft, and spacecraft. The vibration damping system includes at least two separate layers of solid material that are typically substantially clear at visible wavelengths, in which the two layers are spaced-apart by a predetermined distance to form a space or gap therebetween. This gap will be of a size and shape to enhance vibration damping when it is filled with a gaseous compound, such as air. The air-film vibration damping system created by the above structure can be applied to an external pane of a window structure, or to the interior pane of a window structure, or perhaps to both an exterior pane and an interior pane of the same window structure, if desired.

Abstract: An apparatus and method for attenuating noise and vibration in a propeller aircraft comprises a tuned vibration absorber adapted to be mounted to the skin of a fuselage of a propeller aircraft. The tuned vibration absorber may be tuned to the second harmonic of a blade passage frequency of a propeller of the aircraft. The tuned vibration absorber may be connectable to a separately formed mount, which can be mounted to the fuselage skin independently of the tuned vibration absorber. The apparatus may include a cover to prevent interference between the tuned vibration absorber and other components in the aircraft. The apparatus may be used in combination with other attenuation systems to attenuate noise and vibration over a broad range of frequencies.

Abstract: An improved vibration damping system is provided for use with window structures. The window damping system employs both air-film damping technology and viscoelastic damping materials to increase mechanical and/or acoustic vibration damping in window structures.

Abstract: An apparatus for supporting a molding piece such as a piece of chair molding or crown molding against a wall surface at a prescribed distance from a floor surface. The apparatus includes an elongate body having opposing first and second ends and a head assembly coupled to the first end of the elongate body. The head assembly is configured to encapsulate and support a portion of the molding piece that is disposed adjacent the wall surface at a prescribed distance from said floor surface while the second end of the elongate body is disposed adjacent to the floor surface and the first end of the elongate body is disposed adjacent the wall surface. The apparatus thereby supports the encapsulated portion of the molding piece that is disposed adjacent the wall surface at said prescribed distance from said floor surface without further intervention.

Abstract: An apparatus for supporting a molding article that is to be cut by a sawing device. The apparatus includes a bottom supporting surface having opposing front and rear edges and opposing first and second side edges. A first wall is included that is upstanding from the rear edge of the bottom supporting surface and substantially extends between the opposing first and second side edges of the bottom supporting surface. A second wall is upstanding from the bottom surface and at a location intermediate the first wall and the front edge of the bottom supporting surface. The second wall preferably extends between the opposing first and second side edges of the bottom supporting surface.

Abstract: A damper that provides damping for turbine engines to reduce vibrations in the blades, vanes, shrouds, ducting, liner walls and/or other components of the turbine engine. The damper includes an air cavity in a blade, vane, shroud or other engine component and a material covering at least a portion of the air cavity. Vibrations in the turbine engine and its components produce movement of the air inside the air cavity resulting in a corresponding viscous force that dampens the vibrations.

Abstract: A head-up display (HUD)/head-down display (HDD) system capable of projecting multi-color images employs cholesteric liquid crystal elements, two-state liquid crystal devices, an image source, a beam splitter, and a combiner to, in sequence, generate HUD and HDD images. An LCD and cholesteric liquid crystal element operate together to selectively transmit or block portions of an image incident thereon. The switching frequency of the LCD-cholesteric liquid crystal element is above the flicker-fusion frequency, such that both the HUD and HDD displays appear to the observer to be simultaneously and continuously operating.
