There is no acceptable urine or fecal containment waste management system for long duration missions for use by crew members confined to pressurized space suits available. Omni's proposed solution is to integrate its new patent pending urine collection and containment system technology, ProRen FLO (Prosthetic Renal Flow System), combined with Omni fecal collection and containment options into a In-Suit waste management System Garment.


A processing plate assembly for mounting to a homogenizer and for holding tubes containing samples to be homogenized. The processing plate assembly includes a mounting structure and one or plural tube holders. The mounting structure removably or permanently mounts to the homogenizer and can be provided by for example a flat plate-like mounting structure. The tube holders are attached to the mounting structure and hold the tubes in generally tangential use positions with a centroid of each tube positioned along a longitudinal axis of the tube and axially offset from a radius line of the processing plate that is perpendicular to the tube axis. In this way, the homogenizer imparts sinusoidal swashing forces on the tubes that urge the tubes forward into securement in their tube holders and that produces improved homogenization in the tubes.

Circuits and methods are implemented via a plurality of switches, a set of at least two capacitors, at least one voltage amplifier, and an operational amplifier. In one example, during the sampling phase at least one input voltage is sampled, and during the transfer phase at least a first reference voltage provided by the at least one voltage amplifier is subtracted from the at least one input voltage using the operational amplifier. The same set of at least two capacitors may be used in both the sampling phase and the transfer phase.
