Multi-Purpose Split-Duct System for Cables

The cable industry uses cylindrical one-piece ducting, but installing cables in such a duct is labor-intensive, difficult, time-consuming, and expensive. This split-duct system features a patented extrusion manufactured from highimpact ABS plastic. The duct sections are hinged together along a longitudinal edge with an integral hinge and “snap” closing system. The system is placed in a trench in a “double-U” configuration and the cables are then laid into the duct. Once the cables are laid, the other half of the ducting system snaps into place, locking the two halves firmly together.

The ducting system can also be placed above ground or in ceilings, and comes in a standard length of 3 meters, including bends, tees, and offset sections.

Method of Making Textile Articles Impregnated with Predetermined Levels of Antibacterial Activity

This invention is a method for impregnating textiles with a predetermined amount of durable antibacterial materials (inorganic compound). BacterProof™ is a patented method for embedding an inorganic compound that kills both grampositive and gram-negative bacteria. The inorganic compound is embedded into synthetic fibers like polyester and nylon, which is then blended with cotton in a procedure that produces a fabric with superb antibacterial properties. Any bacteria that comes into contact with the BacterProof™ will be killed before it has a chance to multiply and infect the patient or be transferred to another patient by medical staff. In addition to being self-disinfecting, the fabric is nontoxic, allergy-free, odorless, and contains no chemicals.

Non-Damaging Cell Wall Defrosting Method and Apparatus

A defrosting technology was developed to protect cell walls and the quality of frozen products during defrosting. Potential applications include the medical and pharmaceutical industries, cosmetic materials, and foods. The system seldom breaks cell walls because of its quick temperature rising and its high-level uniform heating. In the frozen food field, this system can prevent dripping, and loss of quality and nutrition.

Microencapsulation Technology

Unique Technologies

A flexible, platform microencapsulation technology can be applied to actives from water soluble to water insoluble materials at the 20–35% range; loading levels of up to >50% have been achieved for some actives. The microcapsules protect the actives from environmental conditions, and can be designed to release their core materials in a controlled manner over a designated period of time or by a trigger (temperature, etc.). The capsules can be designed to have multiple cores that can either be contained throughout the inner core of the capsule or seeded in the shell (or both). These “seeded” microcapsules could be used in abuse-resistant pharmaceutical formulations, and could also be applied in a tableting process. The technology increases the bioavailability of pharmaceuticals difficult to formulate and can solubilize them.

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.

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%.

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.

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.
