Abstract: An assembled ring shroud is provided. The assembled ring shroud may comprise a cover, a first ring layer, a key layer, and a second ring layer. The cover may operatively wrap around, contain, and secure the first ring layer, the key layer, and the second ring layer. The key layer may comprise a key that may act for position and anti-rotation. The key layer may comprise spacers to hold the keys in place. The first ring layer and the second ring layer may be configured to provide further strength and support to the assembled ring shroud.

Abstract: A replacement light bulb assembly for use in an incandescent light fixture utilizes a light emitting diode (LED). An LED is bonded to a base that fits within a typical incandescent light bulb fixture. The LED is electrically connected to the base and a center post within the base to form an electrical circuit when assembled within an incandescent light fixture. A control is connected to the LED to modify the LED output. The control can also be used to modify the voltage or current requirements of the light bulb assembly for use with DC current or AC current applications. An external shield or lens, or an internal shield or lens, may be added to the light bulb assembly or directly to the LED to alter the light emitted. Several variations of the light bulb assembly having each having base corresponding to a typical incandescent light bulb fixture may be available.

Abstract: A quadrail ergonomic apparatus includes two or more pathways designed to permit movement in two or more directions mounted to a static object above a surface. One or more carriages designed to move in two or more directions are disposed within the pathways. Each carriage is suspended above the surface from the pathways and capable of maintaining a workload in place and permitting movement of the workload in at least four directions.
