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.

Highly Power-Aware Digital Extravehicular Activity (EVA) Radio

As NASA embarks upon deep-space human exploration, the next-generation extravehicular activity (EVA) radio will be a pivotal technology and an integral part of lunar surface systems success. It facilitates surface operations, enables crew mobility, and supports point to multi-point communications across rovers, landers, habitat, and other astronauts. Driven by Com - m unications, Command, Control, and Information (C3I) interoperability, stringent power budgets, and miniaturization, this mobile radio platform has become increasingly complex. To achieve the overarching communication goals of small form factor, ultrapower, and reconfigurability, NASA needs to advance power-aware processing technology.

Technology to Convert, Concentrate, or Dry Oil-Based Emulsions, Dispersions, or Liquids Into a Dry Powder Form

A company supplies a variety of chemicals, including inverse emulsions that consist of a very-high-molecular weight, water-soluble polymer dispersed in a continuous oil phase. The typical ratio of the key components is approximately 1:1:1 (polymer:water:oil). The company seeks to convert these emulsions to a water-soluble, powdered form, without losing any of the polymer properties. The problem is particularly difficult due to the oil in the emulsion. The oil is an aliphatic hydrocarbon with a low vapor pressure (0.023 kPa at 20ºC) and a distillation temperature of 255ºC.

Delivery System to Modify Release of Organic Agricultural Compound

A company’s current product is applied in granular or prill form, and a coating acts to inhibit the release of the product within. The company is looking for a method to modify the release of the organic compound. The compound becomes active when it comes into contact with external reagents in the area of application. Moisture, pH, temperature, and soil types are the influencers. The solution may come in the form of encapsulation, a barrier method, or a novel mechanism that modifies the release rate of the product in granular or prill form.

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.
