Abstract: A software platform preferably delivered via the internet provides access to and from web-enabled devices with the purpose of delivering and providing software applications, hardware resources, reporting, monitoring, tracking, virtual and cloud computing augmentation, all through a cross-end point unified user-based interface. Resources can be connected dynamically to other resources through the platform and, depending upon the decision of the user and the security settings, resources of the end-point device can be provided to other members in the same network.

Abstract: A USB-based isolator system conveys USB signals between a pair of galvanically isolated circuit systems and supports controlled enumeration by a downstream device on upstream USB signal lines. The isolator system provides a multi-mode voltage regulator to support multiple voltage supply configurations. The isolator system further provides control systems for each of the isolated circuit systems and provides robust control in a variety of start up conditions. Additionally, the isolator system includes refresh timers and watchdog mechanisms to support persistent operation but manage possible communication errors that can arise between the isolated circuit systems.

Abstract: The average strength of a pull plug weld is increased and weak bonding eliminated by providing a dual included angle at the top one third of the pull plug. Plugs using the included angle of the present invention had consistent high strength, no weak bonds and were substantially defect free. The dual angle of the pull plug body increases the heat and pressure of the weld in the region of the top one third of the plug. This allows the plug to form a tight high quality solid state bond. The dual angle was found to be successful in elimination of defects on both small and large plugs.

Abstract: Friction Pull Plug Welding (FPPW) is a solid state repair process for defects up to one inch in length, only requiring single sided tooling (OSL) for usage on flight hardware. Experimental data has shown that the mass of plug heat sink remaining above the top of the plate surface after a weld is completed (the plug heat sink) affects the bonding at the plug top. A minimized heat sink ensures complete bonding of the plug to the plate at the plug top. However, with a minimal heat sink three major problems can arise, the entire plug could be pulled through the plate hole, the central portion of the plug could be separated along grain boundaries, or the plug top hat can be separated from the body. The Chamfered Heat Sink Pull Plug Design allows for complete bonding along the ISL interface through an outside diameter minimal mass heat sink, while maintaining enough central mass in the plug to prevent plug pull through, central separation, and plug top hat separation.

Abstract: Friction Pull Plug Welding is a solid state repair process for defects up to one inch in length, only requiring single sided tooling, or outside skin line (OSL), for preferred usage on flight hardware. The most prevalent defect associated with Friction Pull Plug Welding (FPPW) was a top side or inside skin line (ISL) lack of bonding. Bonding was not achieved at this location due to the reduction in both frictional heat and welding pressure between the plug and plate at the end of the weld. Thus, in order to eliminate the weld defects and increase the plug strength at the plug ‘top’ a small ‘hat’ section is added to the pull plug for added frictional heating and pressure.

Abstract: Friction Pull Plug Welding (FPPW) is a solid state repair process for defects up to one inch in length, only requiring single sided tooling (OSL) for usage on flight hardware. Early attempts with FPPW followed the matching plug/plate geometry precedence of the successful Friction Push Plug Welding program, however no defect free welds were achieved due to substantial plug necking and plug rotational stalling. The dual chamfered hole has eliminated plug rotational stalling, both upon initial plug/plate contact and during welding. Also, the necking of the heated plug metal under a tensile heating/forging load has been eliminated through the usage of the dual chamfered plate hole.

Abstract: A storage rack for displaying flat, rectangular articles such as record jackets along a wall surface. The rack is comprised of at least two elongated rack members mountable to a support in transverse alignment for receiving opposed side edges of the article. The rack members are grooved to receive the opposed article side edges. The openings are spaced outwardly of integral support surfaces at bottom ends of the grooves. These support surfaces bear the weight of the articles at corners thereof adjacent the opposed article side edges. An article can be removed from the rack simply by moving the article longitudinally clear of the support surfaces, shifting the article outwardly into alignment with the access opening and pulling the article longitudinally from between the rack members.

Abstract: A vehicle powered to move about on a front drive wheel and rearward supports, preferably a pair of wheels. The rear wheels are mounted to the frame by a steering control mechanism that facilitates pivotal steering movement of the rear wheels about two axes - a steering axis and a steering control axis. The steering control axis is coaxial with the rear wheels and is perpendicular to the steering axis. The angle of the steering axis may be varied about the steering control axis. Steering is accomplished by the rider shifting his weight from one side of the vehicle to the other. He may shift the steering axis to a position substantially parallel with the ground surface so the frame may be tilted like a bicycle in wide, sweeping high speed curves. The rear wheels then track behind the front wheels as the frame tilts about the steering axis. If the rider shifts the steering axis to a position nearly perpendicular to the ground, he may negotiate short radius, low speed turns.
