Abstract: An electrical storage device includes high surface area fibers (e.g., shaped fibers and/or microfibers) coated with carbon (graphite, expanded graphite, activated carbon, carbon black, carbon nanofibers, CNT, or graphite coated CNT), electrolyte, and/or electrode active material (e.g., lead oxide) in electrodes. The electrodes are used to form electrical storage devices such as electrochemical batteries, electrochemical double layer capacitors, and asymmetrical capacitors.

Abstract: A sleeve generally shaped as a limb and an overlapping area of curvature formed in the sleeve extending a length of the sleeve. A clasp is formed from slicing the overlapping area of curvature the length of the sleeve along a line substantially perpendicular to a transverse plane to create a first end and a second end. The sleeve is openable to separate the first end and the second end of the clasp for fitting the sleeve around the prosthesis and latchable by fitting the first end of the clasp over the second end of the clasp.
