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.

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.

Topical Products to Suppress Pain During Epilation

A company is seeking topically applied products and/or chemical technologies to eliminate or suppress pain sensation associated with epilation of undesired hair from skin. Pain elimination or suppression should be quick (<5 minutes) upon application on skin, and the effect should be temporary (lasting about 30 minutes), similar to topical anesthetics. Products can be in the form of liquid, gel, cream, or lotion to easily apply or spray on skin; should not have any undesired side effects on skin (irritation, itching, redness); and derived from natural sources and with herbal properties.

Crush/Cut-Resistant Safety Glove

A company seeks existing materials that can be utilized in applications for a safety glove. This material must be cutresistant, flexible, and withstand oily, wet, muddy conditions. The material covering the top of the hand and fingers must be extremely flexible and designed to protect the hand and digits from being crushed by dispersing the area of impact from the initial blow. The mold for the top area of the hand must have emphasis on complete coverage without hindering normal movement.

Dr. Drake Deming, Senior Scientist, Solar System Exploration Division, Goddard Space Flight Center

Dr. Drake Deming, former Chief of Goddard Space Flight Center’s Planetary Systems Laboratory, currently serves as Senior Scientist with NASA’s Solar System Exploration Division where he specializes in detecting and characterizing hot Jupiter extrasolar planets. Dr. Deming was named recipient of the 2007 John C. Lindsay Memorial Award, Goddard’s highest honor for outstanding contributions in space science, for his work in developing a way to detect light from extrasolar planets and use it to measure their temperatures.

Lithium-Ion Batteries Fuel the Future of Automotive Design

In 1924, General Motors president Alfred P. Sloan Jr. devised annual model-year design changes in order to maintain unit sales. Body shapes faced cosmetic changes every year, whether or not the underlying automobile had changed. This breakthrough strategy had widespread effects on the automobile business, automotive design, and eventually the United States economy. In recent years, amongst a worsening economy and a struggling auto industry, the underlying automobile has changed rapidly, with emphases on efficiency and environmental friendliness.

nBn Infrared Detector Containing Graded Absorption Layer

Potential applications include environmental monitoring, firefighting, law enforcement, and medical diagnosis. It has been proposed to modify the basic structure of an nBn infrared photodetector so that a plain electron-donor-type (n-type) semiconductor contact layer would be replaced by a graded n-type III–V alloy semiconductor layer (i.e., ternary or quarternary) with appropriate doping gradient. The abbreviation “nBn” refers to one aspect of the unmodified basic device structure: There is an electron-barrier (“B”) layer between two n-type (“n”) layers, as shown in the upper part of the figure. One of the n-type layers is the aforementioned photon-absorption layer; the other n-type layer, denoted the contact layer, collects the photocurrent.
