Mathematically Lossless Compression for Real-Time Medical Imaging

Qbit’s proprietary line of data compression software offers 100% mathematically lossless data reconstruction that ensures that every bit is reconstructed. It allows for an increase in digital throughput, workflow speed, and acts as an enabling technology for applications that require real-time digital content delivery, such as enabling real-time content delivery between a medical image acquisition system such as a 64-slice CT and the workstation system.

The small software “footprint” of the Qbit codec also makes it suitable for use in memory-limited devices as well as chipembedded applications. It can natively handle any raster size, unlimited color planes, and floating-point formats. It is parallelized, so it may perform better than real-time if required.

Automated, In-Process Method for Surface Contamination Inspection of Panels

This patented surface contamination detection system enables accurate, automated, in-line inspection of metallic and composite panels prior to bonding, coating, painting, or welding operations. This technology is currently used for realtime, in-process panel inspection at a leading U.S. aircraft manufacturer, where detecting surface contamination before subsequent operations has resulted in lower scrap and rework cost, and improved customer satisfaction. The technology is transferable to any applications where surface contamination of metal or composite panels is undesirable, necessitating the need for in-process inspection.

This method and apparatus incorporates infrared imaging technology and automated multiple cameras to enable accurate, reliable, and automated detection of contaminants on metallic and composite panels. This technology makes surface inspection feasible for high-throughput processing lines.

Orthobiologics to Treat Spine-Related Diseases

This organization seeks new orthobiologic technologies that stimulate bone growth, provide a growth scaffolding, and promote bone healing through osteoinduction (bone formation is actively induced) and osteoconduction (where a scaffold facilitates bone repair passively) in spinal fusion repairs. They are also seeking FDA-approved elastic materials with strength and stiffness close to cortical bone.

Maintain Food Crispiness from Freezer Storage to Microwave Preparation

Methods are sought to replicate the texture of crunchy food in a convenience food stored in a freezer and prepared in a microwave oven. All ingredient-based solutions must be GRAS (generally recognized as safe) for human consumption. Cost must be within 1 to 2 cents per pound for the final product, and cooking time, once out of the box, must be complete in 4 to 6 minutes. Storage time for the packaged food should be 18 months in a home freezer.

Reusable, Dry Adhesive Material Utilizing Vertically Aligned Multiwalled Carbon Nanotube Array

A novel dry adhesive is being developed that can mimic the hairs on a gecko's foot using vertically aligned multiwalled carbon nanotube (CNT) array. The use of CNT array as dry adhesive material allows reproducing biological adhesion structures and generates fairly strong adhesion strength (over 100 N per centimeter square). CNTs are known to have extraordinary mechanical, thermal and electrical properties. This adhesive can be bent repeatedly with large deflection without failure, which intrinsically results in a reusable or re-attachable dry adhesive. The highly hydrophobic property of CNTs makes them free from the clumping problem, which the polymer based synthetic hair structures face. This product's adhesion is so effective it can be directly applied to glass.

Reusable Adhesive Thermal Interface Material (TIM) To Improve the Contact Thermal Conductance

Current TIM technologies include thermal greases or pastes, phase change materials, solders and thermally conductive adhesive tapes. The thermal conductivity of the best thermal greases available in the market are on the order of 10^5 W/m^2 -K. However, thermal greases, which are single use applications, are oily so their utilization is messy, making them difficult to apply in a thin, uniform coat. This reusable technology employs vertically aligned carbon nanotubes (CNTs) to bridge the interfaces. By using a CNT array as dry interface material, his technology can perform as a thermally conductive tape that provides not only good thermal conducting ability but also strong mechanical bonding between the mating surfaces. It has been shown that a small fraction of CNTs as filling material could induce a 125% enhancement in thermal transport. This interface material can be directly applied to any interface that needs high thermal conductivity.

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.

Delivery System for Controlled Release of Actives

A technology is sought that will enable delivery of active cleaning compositions triggered at a specific time/place by a large range of conditions. The solution must be environmentally safe, must function at a pH range between seven and 11 and temperatures between 5 and 80°C, be compatible for use with chemicals in liquid or solid form, and be suitable for use in a mass-market consumer product. It must not inhibit homogenous mixing of the active material into solutions or onto substrates after dispensing.
