Abstract: A self-contained, washable, portable, shadow screen kit is provided, which includes a generally rectangular side-and-back exterior enclosure, a light source, and a stretched front shadow screen. In one aspect, the side-and-back exterior enclosure includes four corner upright posts supported by four bases, four top horizontal rods connecting the corner upright posts, and drapes to prevent light bleed. Preferably a mirror, mirror stand, and a lightweight ceiling comprising a darkening structure (such as rigid panels or blackout fabric) supported by a ceiling frame are also included. A shadow, cast on the back of the taut screen, is viewable from the front for entertainment or photography. An opaque object is positioned between the light from the light source and the screen. The shadow screen kit is particularly suited for shadow dancing, photography, or videography. The shadow screen kit is easily assembled and disassembled for transport between venues or for storage between uses.

Abstract: A modular suspension system for automobiles and trucks. The present invention relates to a suspension system which is both modular in design and specifically manufactured for high performance wheeled vehicles. This system has multiple modular parts which enable the system to function in various makes and models of vehicles. The modular aspects of this system also enable the cradle to be removable so that the engine and transmission of the vehicle can be easily reached. The modular aspects also allow this system to be set-up with a traditional shock configuration or with a rocker set-up shock system.

Abstract: A bridge monitoring system uses laser light reflected from structural members of a bridge to create velocity and displacement time signals of the bridge's vibratory response to quiescent conditions, and converts the sensed velocity and displacement time data to frequency domain data to provide a “signature” waveform for the bridge indicative of its structural characteristics.
