Microbial-Based Lawn-Care, Pond-Care, and Cleaning Technologies

Proprietary microbial systems use naturally occurring microbes in lieu of chemicals in fertilizers, microbial inoculants, cleaning products, and pond treatments. Products are based on incorporating beneficial micro-organisms with a variety of task-specific organic surfactants, microbial nutrients, fertilizers, cleaning agents, and bio-polymers. The micro-organisms produce enzymes that continue to work even after cleaning, or — in the case of lawn and pond care — continue to make the soil or pond healthier even after fertilizing the plants or inoculating the water.

Analytical Technique for Healthcare and Industrial Applications

Aria Analytics is commercializing a novel analytical technology to characterize liquids for healthcare and industrial applications. As a drop of liquid evaporates on the vibrating quartz sensor, it undergoes distinctive phase changes representing the unique chemical and physical characteristics of the sample. This unique “fingerprint” represents information that is not readily available from any combination of analytical methods currently in use.

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.

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.

Up to Ten-Fold Production Increase for Deep, Heavy-Oil Fields

In oil field tests over 18 months, Direct Current Electrical Stimulation has shown up to a 10X increase in oil production for deep, heavy oil. The predominant method for recovering heavy oil is steam, but steam is limited to depths of 2,500 feet. There are no inherent depth limitations to Direct Current Electrical Stimulation. This patented technology — electrically enhanced oil recovery — uses direct current electricity to both heat and electrochemically upgrade the oil in situ, allowing for economical recovery.
