Abstract: Methods and systems to control stacked hexapod platforms for use as tools, which function with both high accuracy and high precision are provided. In some embodiments, the methods and systems include a convergence of modern control theory, and machine learning. Furthermore, some embodiments provide control algorithms to carry out autonomous in-space assembly operations using assemblers. Some embodiments provide methods and systems which combine long-reach low precision manipulators and smaller, high-precision assembler with interchangeable tools.

Abstract: Provided herein are organic solvent-based processes for the removal of rubber from non-Hevea plants such as guayule shrubs. By the use of the processes, solid purified rubber can be obtained that contains 0.05-0.5 weight % dirt, 0.2-1.5 weight % ash, and 0.1-4 weight % resin (when it has been dried so as to contain 0.8 weight % volatile matter).

Abstract: A unique point absorber type wave energy conversion device is disclosed that includes a Power Take Off (PTO) which uses a torsion spring to return a vertical shaft to its original position after being rotated by a rope or cord that pulls a reel via a guide system. This spring return allows the PTO and housing to stay stationary under the wave energy while a buoy at the surface provides an oscillating linear movement. The oscillating rotary motion caused by the interaction of the buoy and spring is converted into a one directional motion via a one-way clutch and is transmitted to generators using a gearbox that increases rotational speed.

Abstract: A method is provided to perform an anterior cervical microdiskectomy to remove at least one bone spur on a pair of adjacent vertebrae in a spinal column that includes a posterior longitudinal ligament. Each vertebra contacts a disk positioned therebetween. The disk includes an annulus and a nucleus. The method comprises the steps of removing a portion of the annulus of the disk; removing the nucleus of the disk; removing the vertebral plates with a first burr; removing a portion of the bone spur with a second burr having a spherically shaped abrading head; and, providing a third burr. The third burr comprises an elongate shaft having a distal end and a proximate end; and, a head attached to and extending outwardly from the distal end of the shaft. The head includes a smooth end surface; and, a smooth rounded peripheral edge circumscribing the end surface.

Abstract: The fluid expander includes a housing, a drive shaft mounted for rotation within the housing, a piston-cylinder assembly including a cylinder and a piston disposed within the cylinder for converting energy from a working fluid to rotational energy output via a drive shaft. Various adjustment assemblies are provided for adjusting speed, torque, stroke length, and thermodynamic cycles of the device. The fluid expander assembly can be used with external combustion systems, with solar or geothermal energy systems, or with internal combustion systems.
