Abstract: Methods and systems for isolating objects from seismic vibration, isolation flooring systems, vibrational damping devices, and methods for their use are disclosed. The present invention has the advantage of having a minimum of moving parts, and being extraordinarily easy to install and inspect. In preferred embodiments, the invention is drawn to methods of isolating sensitive objects from the full extent of seismic vibrations.

Abstract: In a home system in which a TV receives video from various sources over directional wireless links such as 60 GHz links, a mirror apparatus is provided that can be configured to physically steer a signal toward a receiver on the TV to optimize received signal strength. In this way, RF energy that otherwise would be radiated in non-productive directions away from the receiver is reflected toward the receiver.

Abstract: A raceway extends along an edge of roof of a structure and is adapted to house a cable, such as an industry standard ice and snow melt heating cable designed, listed and approved for the purpose. An open side of the raceway exposes the cable and allows for the insertion, replacement and inspection of the cable per industry practice. A side of the raceway may have a radiused edge providing added resiliency to springably retain and/or removably secure the cable in raceway. In the case of a heating cable, heat is transferred to the surrounding structure, and may be concentrated at the drip edge to maximize ice melt efficiency. Methods of installation of the raceway are applicable to new construction and retro-fitting existing structures, including drainage systems, bridge structures and other outdoor enclosures, and may be used with many types of roofing materials including asphalt, wood and metal.
