Through-Metal RFID Tags Resist Harsh Environments and Deter Counterfeiting

These patented 125-kHz RFID tags and readers enable tag information to be read and written through metal so that tags can be hermetically sealed inside metal parts such as surgical instruments, construction forms, weapons, and similar devices that must withstand harsh environments. MBBS tags can resist high temperatures and pressures (240°C, 2000 bar), acids, chemicals, and similar conditions. At the heart of each tag is an integrated circuit that can store up to 2 Kbits of rewritable data. The tags can be inserted directly into parts and other devices to build a permanent and robust tagging system. Tags have also been designed as anti-counterfeiting IDs, where the tag self-destructs if the factory- sealed container has been opened. The tags employ a flat air coil that uses no ferrite, as an antenna. MBBS reader technology offers an emitter and receiver that have been optimized for operation with metal tags.

Innovative Cooling Technology for Circuit Boards with LED Lights

Advanced Solid State Lighting (SSL) is a technology that enables the use of LED lights in cost-sensitive applications where cooling of the LED is needed. One limitation that has hindered LED light designs in commercial applications is the cooling of the LEDs when used in the continuous duty of commercial applications. This patent-pending solution for cooling LEDs should advance the penetration of LED designs into the commercial and industrial lighting market. SSL allows for design flexibility to scale the number of LEDs needed for an application. It uses current manufacturing methods and processes from the electronics industry, and the cooling concept can be applied to other PCB applications. SSL provides enough cooling that fans or heat sinks are not required. LED operating temperatures can be reduced by 20°F or more. SSL helps meet government-mandated energy reduction goals for large corporate buildings, and achieves longer life than current high bay lights.

Emissions Control System Provides up to 100% Removal

This emissions control system effectively reduces up to 100% of hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) from fossil fuel combustion engines. It is suitable for gasoline, natural gas, propane, syngas, and diesel engines. The Emission Reduction System technology is recyclable and does not create additional toxic emissions. It is made from low carbon steel or stainless steel. The system features direct bolt-on replacement of original manufacturer equipment for most makes and models, and can reach operating efficiency within 9 seconds of engine startup. It is available with a silencer, and features high sound attenuation. For automotive applications, it improves operator and passenger safety by removing CO, NOx, and HC before they can enter the cabin. High flow capacity prevents back pressure to maintain maximum horsepower. The system allows for virtually pollution-free idling when idling is necessary.

Lossy Compression Technique Varies Data Quality in Response to Bandwidth or Time

Looking at ways to encode an image as a file, one byte in the file contributes information to one pixel (PPM files) or a small group of pixels (GIF, JPEG). In other image technologies such as wavelets, certain bytes contribute much more information than others. Lossy compression technique can vary data quality in response to bandwidth or time. Using this technology, data is encoded so that every byte in the file contributes a little information to all the pixels in the image. If a group of bytes is missing, an image can still be reconstructed from the remaining bytes. The technology represents content as projections of highdimensional polygonal lines on smaller subspaces. The content can be reconstructed regardless of the order of the projections. Moreover, an approximation of the content can be reconstructed with a partial subset of projections.

Single-Layer Electrochromic Polymer Technology for Automotive and Architectural Glazing Light Control

DuPont’s electrochromatic (EC) technology for controllable light transmission in automotive and architectural safety glazing applications is based on an organic polymer film that can function as a controllable EC interlayer. This technology addresses the need for reducing the complexity of current EC technologies and can be used in rigid and flexible forms, large sizes, and curved shapes. It has applications in dynamic electrochromic glazing systems that undergo a reversible change in color from light to dark by application of a very low voltage. Target markets in automotive include sunroofs, mirrors, instrument clusters, windshield shadebands, sidelights, and backlights. The technology works either in transmissive or reflective mode. Transmissive EC devices are made with indium tin oxide electrodes that are fully transparent in the visible spectral range. All of the components of the electronic control systems are commercially available. Get the complete report on this technology at: Email: nasatech@yet2.com Phone: 781-972-0600

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.

Anti-Reflective Coating for Films

Able to withstand abrasion even with steel wool, these antireflective coating formulations for display applications offer high durability and reflectivity that ranges from 1.2% down to 0.5%. Reducing ambient light reflectance significantly improves image clarity on LCD and PDP displays and rearprojection televisions, especially in daylight or outdoor conditions. Lenses and other optical equipment may be additional applications. This DuPont technology is a single-pass roll-toroll (microgravure) coating process. Because of its refractive index and thickness, light reflected by the underlying substrate is out of phase with light reflected from the front surface. The two phases cancel each other out, dramatically reducing reflectance and improving image clarity. All the formulations offer exceptional adhesion to the substrate, a neutral color, and exceptional durability. The single applied coating spontaneously forms two layers to improve scratch resistance, adhesion, and improved optical benefits.
