Single-Motion Extension Mechanism for Poles

Originally developed and marketed as an extension pole for painting, light bulb changing, and similar operations, the single-motion extension principle in this technology is adaptable to any rod or pole that must be extended and retracted to a compact length. It applies to extendable antennae; tent poles; emergency equipment such as stretchers, cots, or IV poles; tools; robotic arms; or surgical instruments that must extend and retract once in the body. The internal mechanism uses a metal tape similar to that in a retractable tape measure that pushes on the extending tube. The mechanism may be hand-operated or motorized, but either way, a single motion extends the pole. The internal, contained mechanism of the extension pole provides a singlemotion extension to about three times the collapsed length of the assembly. The assembly can be fabricated in a variety of materials in a variety of tensile and compression strengths in multiple segments. The assembly can scale up to greater lengths or be miniaturized to suit the application.

Odor Removal From Recycled Plastics

This technology removes odors from recycled plastics, especially high-density polyethylene (HDPE). Odors absorbed from household or industrial liquids do not affect physical properties of the polymer, but make the recycled plastic unsuitable for consumer goods. Trace amounts of polyethylene imines blended with the recycled plastic remove aldehyde odors typically resulting from rancid fats and oils. The technology also includes a process for manufacturing odor-free films from recycled plastics. This technology comprises a process for preparing a blend of recycled polymer and polyalkylene imines (PAI). The present technology includes another process for preparing films, molded articles, or thermoformed articles by a compounding or masterbatch process. The method of producing the blend is not material as long as a relatively uniform distribution of the PAI polymer through the recycled polymer is obtained. It is preferred for the blend to have intimate mixing of the polymers, i.e. microscopic distribution of PAI through the recycled polymer.

Green Sewage Treatment and Water Purification Technology

A green sewage treatment and water purification technology combines water with fertilizer and biomass production. The sustainable water treatment system produces biofuel and organic fertilizer, and extracts carbon from the atmosphere. No electric power is required for sewage treatment, filtering, and water cleaning. The system uses no chemicals, and can run in heavy rain without hazardous overflow. It also stays intact in dry seasons, even for several months without rain. The system combines two layers of microbiological water treatment: an upper layer with aerobic activity and a lower layer with anaerobic activity. Since the upper layer covers the lower layer, no anaerobic gas production can escape into the atmosphere. Due to the optimized design, the clarifying power and productivity of the system is much higher than in other single-layer wetlands. Benefits include an extremely compact and effective design, protection of the lower layer by the upper layer, integrated liquid transfer, and not generating clearing sludge.

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.
