Abstract: A cryogenic dewar may include an inner tank and an outer tank. The cryogenic dewar may further include one or more longitudinal stiffeners coupled to the inner tank at locations of stress that provide resistance to such stress. The inner vessel may include a combination of longitudinal stiffeners to allow the dewar to meet governmental imposed regulations on strength and safety of the dewar without increasing the weight of the dewar or to increase the amount by weight of cryogenic liquid that can be transported under governmental imposed regulations, or both, by, with the addition of longitudinal stiffeners, simultaneously increasing the grade of the material of the inner tank.

Abstract: A cryogenic dewar may include an inner tank and an outer tank. The cryogenic dewar may further include a plurality of trunnion mounts. A first four of the trunnion mounts may be coupled between a front half of the inner tank and a front half of the outer tank. A second four of the trunnion mounts may be coupled between a rear half of the inner tank and a rear half of the outer tank. The trunnion mount may be further strengthen with a plurality of pie-shaped reinforcing pads welded to each other and to an outer surface of the inner tank.

Abstract: A fluid pumping system may include an engine, an electric generator, an electrically driven pump, and a first electrical resistance heating element. The engine may drive the generator, and the generator may supply power to the electrically driven pump and the electrical resistance heating element. The first electrical resistance heating element may be positioned to apply heat to fluid pumped by the electrically driven pump.

Abstract: An atmospheric water generator (AWG) may be used to extract water from ambient air. A compact screw compressor of the AWG may be used to compress refrigerant, a condenser of the AWG may be used to condense refrigerant, an expansion device, and an evaporator of the AWG may be used to transfer heat from ambient air to refrigerant, causing moisture in the air to condense. The condensed moisture may be collected in a water collection unit.

Abstract: A membrane assembly for use with a three-dimensional imager to obtain a topographical plantar image of a foot is provided. The assembly includes a support structure having a front end and a rear end elevated relative to the front end, and a flexible membrane suspended from the support structure and configured to receive and support an entire plantar surface of the foot. The membrane defines and encloses an upper portion of an inflatable chamber, and includes a forefoot- and a rearfoot-receiving region respectively adjacent to the front and the rear end of the support structure. The rearfoot-receiving region is under less tension than the forefoot-receiving region. The imager is positionable under the membrane in order to acquire the plantar image when the foot is disposed on the membrane. An apparatus including a membrane assembly and a three-dimensional imager, and a method for imaging a foot are also provided.

Abstract: The orthotic is formed of a monolithic semi-rigid resilient shell for engagement inside a footwear and for conformingly fitting against the plantar portion of a patient's foot. The orthotic includes a rear heel cup portion that may have inner and outer rearwardly-extending resiliently deformable arms defining at their rear ends a rearwardly-opened notch therebetween. A number of first grooves may be made along the outer or inner flange of the heel cup portion, on the exposed top or bottom surface thereof. The orthotic further comprises a front end portion for engaging the metatarsal plantar region of the foot, having a sinuous front edge which includes five frontwardly-facing arcuate concavities each for registering wedging engagement therein by a corresponding one of the five metatarsal anterior portions of that person's foot.
