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.

All-Natural Preservative

White mustard essential oil (WMEO) is an all-natural extract from white mustard seeds that delivers broad antimicrobial efficacy against bacteria, yeast, and mold, providing a natural and effective alternative to synthetic or artificial preservatives. WMEO has broad application in beverages, meats, poultry, salads, gravies, and sauces. Maltodextrin and white mustard essential oil are both listed in the Code of Federal Regulations as GRAS (Generally Recognized As Safe) for use in food products.

Flexible Gas-Tight Film

The clay film “Claist,” which comprises a natural or synthetic clay as a main component, exhibits uniform orientation of clay particle laminates. It is flexible, has a mechanical strength sufficient for use as a self-standing film, and has a structure in which laminates of clay particles are highly oriented. The thickness of Claist is 10-100 micrometers, and can be made thicker by layering. The gas permeability at room temperature to hydrogen, oxygen, nitrogen and other inorganic gases is lower than the detectable limit. The gas barrier performance of Claist remains unchanged up to 600°C. Claist is flexible enough to be folded like paper without cracking. The standard Claist film shows a tensile strength of 19.2 MPa and an elongation of 2.2%.

Board Design Test Vehicle

The Board Design Test Vehicle is a method for objective evaluation and qualification of supplier capabilities for the fabrication of multilayer printed circuit boards. It is used to analyze and assess technical capability and reliability of products that are provided by a supplier, and provides a mechanism for supplier improvement with validation. The design incorporates features that allow for analysis of variables data to determine actual process capabilities statistically and accurately, with a minimal amount of effort. Data can be plotted with distributions to determine process capability, revealing whether the data is “filtered” or cherry-picked, and can help evaluate the repeatability and consistency of processes. The ability to validate design rules is provided and matches supplier capabilities to actual designs.

Lactic-Acid-Producing Bacterial Strain

This technology has solved the problem of adding beneficial lactic-acid-producing bacteria (LAB) to both wet and dry foods that undergo processing with heat and pressure. The bacterial strain is able to withstand harsh manufacturing regimes including high- compression tableting, coating, highshear blending, and excessive heating. Previously, most LAB could be distributed only in refrigerated wet foods (such as yogurt) and less than 1% of it survived to reach the digestive tract. The new LAB strain delivers 200 times the beneficial bacteria to the digestive tract over current strains, and has been used in products for the treatment of the symptoms of lactose-intolerance, irritable bowel syndrome, Crohn’s disease, colitis, arthritis, psoriasis, and a number of other digestive problems. It also has been shown to strengthen the immune system, improve absorption of vitamins and minerals, aid in digestion generally, and displace harmful bacteria in the digestive tract.

Database Interrelation Miner

The Interrelation Miner Methodology is a technology for multivariate statistical data analysis and outcome prediction (data mining) of either complex and/or multidimensional data sets, or of very small datasets based on statistical fuzzy set theory. This tool can be applied to any complicated data set with many samples or variables (e.g., micro array data), and provides results for small or incomplete data tables by using very simple decision rules with nonlinear data models. The Interrelation Miner has analyzed gas chromatography/mass spectrometry data and has provided up to 20% better prediction performance than compared approaches. Other possible applications include: microarrays, protein arrays, environmental data sets, food quality control, and quality control in general.
