Tool-Free Engineered Composite Thermoforming Technology

Tooless Engineered Composite (TEC) is a patent-pending process that incorporates the benefits of a thermoformed plastic composite product and the strength of fiberglass reinforcement. This tool-free process utilizes the thermoformed shell as the tool surface in a closed mold process. The result is an extremely durable product with superior finish quality. The product has low to no emissions and uses soy and corn resin. The TEC process utilizes a multi-layer thermoformed shell producing products with a class “A” finish. Utilizing a multi-layer thermoformed shell eliminates painting, which reduces cost and produces low or no emissions. This multi-layer shell has a layer of acrylic that may be sanded and buffed if needed. The thermoformed shell allows for the use of various materials, finishes, colors, textures, and decorative patterns that may be utilized in different applications.

In-Store Hair Analysis Tools

A company is seeking tools and devices that can be used instore to quickly classify hair types based on measured hair properties like hair thickness and/or damage level. Technologies include hair diagnostic devices/tools that can evaluate at least one of the following parameters: structure information; physical properties such as amount of curl, tensile strength, and stiffness; and cosmetic properties such as smoothness, friction, and resistance to frizz. Tools must be easy to use in-store, and results must be sensitive enough to differentiate between ranges of hair types. Respond to this TechNeed at: Email: nasatech@yet2.com Phone: 781-972-0600

Submillimeter-Wave Amplifier Module With Integrated Waveguide Transitions

This technique can be used in submillimeter-wave imaging in homeland security, weapons detection, and commercial test equipment. To increase the usefulness of monolithic millimeter-wave integrated circuit (MMIC) components at submillimeter-wave frequencies, a chip has been designed that incorporates two integrated, radial E-plane probes with an MMIC amplifier in between, thus creating a fully integrated waveguide module. The integrated amplifier chip has been fabricated in 35-nm gate length InP high-electron-mobility-transistor (HEMT) technology. The radial probes were mated to grounded coplanar waveguide input and output lines in the internal amplifier. The total length of the internal HEMT amplifier is 550 μm, while the total integrated chip length is 1,085 μm. The chip thickness is 50 μm with the chip width being 320 μm.

Economical Implementation of a Filter Engine in an FPGA

There are numerous potential uses in general signal processing. A logic design has been conceived for a field-programmable gate array (FPGA) that would implement a complex system of multiple digital state-space filters. The main innovative aspect of this design lies in providing for reuse of parts of the FPGA hardware to perform different parts of the filter computations at different times, in such a manner as to enable the timely performance of all required computations in the face of limitations on available FPGA hardware resources.

Improved Joining of Metal Components to Composite Structures

Uncured composite material is intertwined with metal studs, then cured. Systems requirements for complex spacecraft drive design requirements that lead to structures, components, and/or enclosures of a multi-material and multifunctional design. The varying physical properties of aluminum, tungsten, Invar, or other high-grade aerospace metals when utilized in conjunction with lightweight composites multiply system level solutions. These multi-material designs are largely dependent upon effective joining techniques, which create a “monolithic,” well-integrated and seamlessly functional structure.
