Precision Feedback-Controlled Laser Drilling for Fluid Flow Apertures

This technology provides a method of laserdrilling any component under the control of real-time feedback to provide for predictable, calibrated fluid flow through one or an array of holes formed in the component. The technique can improve flow control through a machined part by an order of magnitude or more over conventional open-loop laser drilling technologies, increasing the predicted lifetime of component parts. The method can be applied to any component or device that requires controlled flow of any fluid.

Diagnostic Pattern Recognition Using Mid-IR Spectroscopy

By applying mid-infrared spectroscopy to bodily fluids, this suite of technologies offers the potential for quick, accurate, and inexpensive diagnostic support for a variety of diseases in humans or animals. Every disease or condition results in quantitative imbalances in the “normally occurring” molecules of the body — raised glucose or cholesterol, for example. Pathogens like bacteria and viruses contribute their own molecular loads as well as destabilizing the body’s “homeostasis;” its usual stable and healthy condition. A spectrographic “snapshot” of sample fluids from blood serum, lymph, and saliva can be matched to the unique spectroscopic pattern of known conditions and diseases. Pattern recognition can then result in a quick diagnosis.

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.

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.

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.

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.

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.
