    Abstract: An implant includes: a sinusoidal container that includes: a plurality of projections; a plurality of troughs; and a plurality of smooth interfaces, wherein a smooth interface is interposed between a projection and an adjacent trough for the plurality of projections, troughs, and interfaces to provide a smooth continuous transition between adjacent projections and troughs. A process for making an implant includes: forming a sinusoidal container from a polymer, the sinusoidal container including: a plurality of projections; a plurality of troughs; and a plurality of smooth interfaces, wherein a smooth interface is interposed between a projection and an adjacent trough for the plurality of projections, troughs, and interfaces to provide a smooth continuous transition between adjacent projections and troughs; and providing a filling tube attached to the sinusoidal container to make the implant.

    Abstract: A dump valve assembly is disclosed. The dump valve assembly has a seat plug, a spring, a standing valve, and a ball. The seat plug is anchored to the standing valve and has two prongs that engage two corresponding slots within the standing valve. By pressing downwardly upon the seat plug, the spring is compressed and the prongs slide downwardly until they engage the ball. By ceasing the downward pressure on the seat plug, the spring relaxes and expands, thereby lifting the ball off of the standing valve in order to open the standing valve for pump drainage.

    Abstract: A monolithic isolator circuit is provided which replaces optocoupler feedback configurations which are prone to wear out, lack reliability, and bandwidth limitations. By communicating only a subset of a sigma delta modulators quantizer across the isolator but closing the modulator loop on the primary side, much wider bandwidth communications of analog information can be achieved than with optocouplers. This allows for the use of the proposed isolator for cycle by cycle loop control and protection functions which previously required components on the local side of the isolation. The monolithic isolator circuit can be extended to isolate analog to digital converters (ADC), analog buffers, and to isolated current sense amplifiers (CSA). The monolithic isolator circuit utilizes a z-domain differential delay line to create an error in conformance with the difference between the feedback magnitude and a reference. Z-domain differential delay lines have a fast response, and may be windowed and event driven making these delay lines very current efficient. The conformance error may be fed to a digital compensator (such as a proportional-integral-derivative (PID) compensator) and finally to a z-domain modulator. The z-domain modulator may be one of several constructions, however, to achieve a reasonable number of bits a delta sigma structure, such as an error feedback structure, is utilized for the modulator.
