Abstract: Systems and methods for buoyancy compensation are provided. Both active and passive buoyancy compensation can be provided using a compressible mixture made of a liquid along with a hydrophopic material such as a powder, electrospun fiber, or foam. The compressible fluid compresses as pressure is applied or expands as pressure is released thereby substantially maintaining an overall neutral buoyancy for a vessel. This allows the vessel to ascend and descend to water depths with minimal active buoyancy change. As a result, the energy usage and the reliance on higher pressure air and oils can be minimized.

Abstract: Embodiments of the present invention generally relates to substrate supports for use in a plasma processing chamber. The substrate supports, which are metallic, have ceramic inserts to prevent arcing between the substrate support and the shadow frame used to protect the edges of the substrate support during processing. In large area substrate processing chambers, the shadow frame may comprise multiple pieces. The individual pieces may be coupled together, but spaced slightly apart by a gap to permit thermal expansion. Ceramic inserts are positioned on the substrate support so that when a shadow frame is positioned adjacent thereto, the ceramic inserts are located adjacent the gaps in the shadow frame. The ceramic inserts adjacent the gap prevent and/or reduce the arcing because the gaps are located over electrically insulating material rather than electrically conductive material.

Abstract: A leash that allows any individual to control a pulling dog without risking injury or walking in an unsafe manner. The disclosed leash maximizes body mechanics and basic pulley/lever principles to achieve more strength. The leash comprises a cuff that preferably wraps around a user's arm above the elbow. Attached to the cuff are a few feet of leash material that freely runs through an O-ring and ends in a handle.

Abstract: A rotary engine has a rotor that has rockers pivoting in chambers. As each rocker pivots, it rotates an outer crankshaft. Each outer crankshaft has a spur gear that engages a stationary ring gear. Spur gear rotation causes the gears and the outer crankshafts to revolve around the ring gear. This cause the rotor to rotate. As the rotor rotates, successive chambers are positioned at the intake, compression, ignition, and exhaust positions. Igniting the fuel in the ignition position pushes the rocker inward to rotate the outer crankshaft associated with that rocker to cause the rotor to rotate.

Abstract: An operator-controllable valve opens or closes an idle air bypass passage in a motorcycle, allowing an operator astride the motorcycle to set an idle position manually. A handle permits a first adjustment by the operator without use of a screwdriver or other hand tool. An additional interface enables a wider range of adjustment using a hand tool. Both interfaces vary depth of an air mixture screw of the valve within an idle air bypass passage of a throttle body. Dual cylindrical members of the valve rotate relative to one another and relative to a base of the valve, each cylindrical member driven by one of the interfaces. Locking the cylindrical members together such that both rotate in tandem upon the operator moving the handle is accomplished by either tightening the handle or tightening a nut coupling the handle to the valve. A handlebar adjustment lever may couple with the handle.
