Finger Seals Replace Brush or Labyrinth Seals

Finger seals are non-contact fluid seals similar in purpose to labyrinth or brush seals in that they act as a barrier between two areas of the same or different pressures, but allow a rotating shaft to penetrate through them from one side to the other. Applications include sealing rotating parts in turbine engines, pumps, rotating air motors, or other applications where a shaft needs to be sealed against incursion or excursion of oil, air, water, or other gases or fluids.

Unique DNA Signature Identifies Organism’s Species

Unique genetic markers called oligonucleotides can provide swift identification of a known organism or rule out an organism from known genomes. This software technology provides a way to generate thousands of such markers and provides a searchable database of chromosomal sequences for over 100 pathogens and near-neighbor organisms, unique plasmid sequences, and markers for virulence and antibioticresistant genes in a platform-independent format. Using the technology, the existing database can be extended to any DNA-based organisms. With as few as 20 DNA fragments, the system can achieve a 99% confidence of no false negatives against a library of samples.

Heating Different Zones of Food in a Microwave Oven

An organization seeks technology to enable foods to become crispy when heated in a home microwave oven. The outer surface should heat and become (or remain) crispy, while the interior body of the food should heat only as appropriate. The organization seeks materials, ingredients, or other technologies that enable the zones, while physically part of the same food, to respond differently to the same radiant microwave energy environment.

Topical Delivery for Analgesic Medications

A company seeks new non-oral delivery mechanisms for analgesics. Non-oral methods avoid the stomach and the intestine. These new mechanisms might be topical; that is, in contact with the outer layer of the skin. However, other nonoral mechanisms are open for consideration. Non-oral administration bypasses both the stomach and the liver and can deliver more active to the bloodstream more quickly per dose.

High-Production Suction Head for Mud, Sludge, and Sewerage Dredging

This technology features a uniquely designed suction head that eliminates problems typically experienced in alluvial diamond mining, mud, sewerage pumping, or dredging operations. This patented system offers a proven solution where no divers are required, and which can be operated from the deck of the ship in the shallow, mid-water, and deep-water operations for 24 hours a day — even on foul weather days.

Detecting Your Level of Hydration

HydroSmart is a new way to determine if you are adequately hydrated at any given time. It is a handheld, portable, simple- to-use device that requires a stream of urine, and the results are given almost instantaneously via a color-changing reagent. A color change corresponds to the specific gravity of the urine specimen. Urine specific is a measure of a person’s level of hydration. The device avoids the need to urinate into a plastic cup, which is normally delivered to another person for lab analysis; a situation that is somewhat embarrassing and most importantly, time-consuming. The reagent is bromthymol blue, poly(methylvinyl ether/maleic anhydride) and an alkaline compound such as sodium hydroxide. It is absorbed on a porous membrane, such as a woven matrix of cellulosic fibers or other substrate material, which can retain the reagent. There is a cap that contains a color chart for comparison with the color resulting from the reaction of the urine and the chemical reagent.
