Cargo Drop Air Delivery System

The ADCA aerial delivery system reduces cargo loading time, is safe for fragile cargo, and allows loading and unloading to be performed by one person (no special training required). The drop container is designed with a tubular frame, padding materials, a shock-absorbing cushion, and side and bottom air bags to withstand impact as it drops to the ground so that the box remains intact and secure. All types of aerial drops (high/low velocity) are possible, and the system is compatible with existing ranges of parachutes. ADCA is very stable, and highly targeted aerial drops can be achieved due to a weighted-bottom feature. The ADCA system comes as a single unit with no parts to assemble and a single unit may be used repeatedly. Applications include humanitarian aid and relief efforts, and resupplying military troops in hostile territory.

Secure-Document Markup Software

Northrop-Grumman The Portion Marking Verification Tool (PMVT) software automates the process of regulatory document marking. This tool assists users in meeting the mandated requirements for portion marking in sensitive or classified documents. By utilizing PMVT, portion marking can be up to 200–400% faster than traditional review processes. PMVT handles all U.S. classification levels; SCI/SAP control channels and dissemination controls; guides reviewers through the classification process; allows reviewers to verify the suggested portion marking and make changes; and searches for words and complex expressions. The building of rule sets is flexible, and rule sets can be created to reflect government classification requirements. Email and other text repositories can be automatically scanned. PMVT is a software-only product integrated with the Microsoft Office environment.

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.

Thin-Film Solar Cell Technologies

Thin-film technologies are sought for dye-sensitized solar cells that are flexible and printable on a plastic substrate; amorphous silicon/microcrystalline silicon tandem solar cells and textured TCO glass; and copper-indium- gallium-selenide solar cells that are flexible and printable on a plastic or stainless steel substrate. Also needed is a quasi-solid-state electrolyte (for outdoor reliability and stability) and a sintering technology to deposit TiO2 paste on flexible substrates at temperatures under 150°C.

Natural Preservatives for Beverages

Organic antimicrobial chemistries are needed to act as natural preservatives for a variety of beverages. They must be safe, stable, colorless, odorless, and tasteless at the concentration necessary to act as a preservative, and be effective at low concentrations (below 1%). They must extend the overall lifetime of the beverage and the nature of the beverage must not change.

Environmentally Friendly Solvents

A specialty chemical company is seeking innovative green, renewable raw materials, products, and processes for replacement of existing non-environmentally friendly solvents while not compromising the performance or significantly increasing the costs. The solutions should be biodegradable, low/non- VOC, low toxicity, and economically competitive. Sources for renewable raw material solutions may include glycerol, sugars, furfural, succinic acid, and bioethanol.

Quantifying Breast-Feeding Volume

A method is sought to provide a real-time quantitative measure of the volume of milk consumed as a baby breast-feeds. The solution must be safe, environmentally sound, non-invasive, retail for under $50, and should not interfere with mother- newborn bonding. It should be compatible with home use and relatively small in size, and should show results in a specific standard or some calibrated multi-point scale.
