Dispensing Closure Technology Seals and Separates Ingredients

StarOne Group The Drop-Top™, a container closure and delivery system, features an internal, multi-cavity design that stores up to three separate doses of ingredients, including liquids, powders, gases, granules, or tablets. The dispensing closure technology increases the shelf life of products that are not stable in oxygen or aqueous solutions, and stores highly sensitive products that cannot have any contact with the environment or specific ingredients.

Sterility Verification of a Flowing Liquid

A client seeks a device capable of detecting contamination in a liquid flow. The system needs to detect non-liquid particles, bacteria, yeasts, mold, and/or spores in a continuous liquid stream. Any proposed sensing methodology must not physically interact with the liquid flowing in the interior of the channel. In operation, the detection system should report any contamination; the nature of the contamination can be determined later. A proposed solution need not identify the specific contaminant. An optical or light-based system is desired, but a variety of technologies may be acceptable if they do not require the fluid flow to be sampled directly.

Fabrics with an Inherent Thickness

A foam shape must be replaced with a knitted, woven, or nonwoven fabric that derives its thickness from the geometric structure of its components. The current application uses polyurethane foams that range from millimeters to 2 cm thick. The foams offer little or no ventilation in a situation where air circulation can be critical. New materials at the fiber level must be used to create a light fabric with a build-in structural thickness and loft. Possible solution areas include mathematical models of knitting matrices and nonwoven manufacturing techniques.

Additives to Minimize Dirt Accumulation

Polymeric and non-polymeric additives must release dirt from stucco, decks, and other coated architectural surfaces. A client seeks hydrophobic surfaces that are hard rather than tacky, and offer low surface tension and high contact angle. Preferably, a homeowner could spray these enhanced coatings with water and quickly wash away accumulated dirt. The additives must be compatible with water-based systems such as acrylics and styrene-acrylics or alkyds, as well as with polyurethanes and epoxies. Technology options must also accept occasional re-coating, and resist standard soaps and household cleaners.

Cost-Effective Cholesterol Tests

A client seeks a simple, small, and cost-effective diagnostic cholesterol test kit. The technology must be used directly by a consumer, possibly as an in-home test kit. Results should be visible immediately and show different levels, including normal, moderately elevated, or high cholesterol. Solutions could be minimally or non-invasive diagnostics that detect one or multiple states, and could include tests for blood, breath, saliva, sweat, urine, or tongue scraping. Ideally, tests must be validated against standard blood cholesterol tests, and detect a 10% change in total cholesterol.

Mechanism Allows Pedals to be Used Together or Separately

Current bicycle mechanisms allow only alternate use of pedals, thus halving possible torque. A new arrangement allows simultaneous use of both pedals. The TEJJ cycle uses the force of alternately pushed pedals to start or maintain momentum. When carrying higher loads or climbing a hill, a rider can also optionally push both pedals simultaneously to increase torque. Springs return the pedals to their optimum driving position, and the main driving gear freewheels even as the pedal returns to the driving position. The new mechanism has application for pedal-driven carts of all kinds, and in pedal-driven vehicles for the disabled.

Technology Tests for Unwanted Microorganisms

Clinical and industrial instruments, clothing, gloves, and work surfaces may contain or acquire microorganisms, which flourish or grow as a function of the environment in which they are located. Such growth may lead to the proliferation of toxin- or allergen-producing pathogenic organisms. Using nucleic acids, a new technology provides a more sensitive, convenient, and less costly way to test for the presence of unwanted microorganisms.
