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.

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.

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.

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.

Multi-turn Encoders Find Home in Industrial Applications

Single-turn encoders have long been used in industrial automation to gauge angular displacement in a broad range of applications, ranging from steering control on a mobile equipment vehicle to boom extensions. A single-turn encoder is a transducer that precisely measures angular displacement over 360 degrees and assigns a value to each position. These values can be decimal, binary or grey code, and systems typically offer up to 17–bit resolution.
