Did You Know...
...that the inventor of the electric motor was a blacksmith named Thomas Davenport? Described as "a brilliantly unsuccessful inventor", Davenport invented the first rotary electric motor. In 1836 he headed out -- on foot -- from his Vermont home to file a patent application at the Patent Office in Washington, D.C. By the time he got there, he had squandered away his money and couldn't afford the $30 filing fee so he turned around and went home. When he later mailed in his application with money he'd raised, the Patent office was destroyed in a fire. He did finally get credit for his invention on Feb. 5, 1837.

It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.AbstractRandom access to arbitrary fields of a video segment compressed using both interframe and intraframe techniques is enhanced by adding state information to the bitstream prior to each intraframe compressed image to allow each intraframe compressed image to be randomly accessed by generating a field index that maps each temporal field to the offset in the compressed bitstream of the data used to decode the field, and by playing back segments using two or more alternatingly used decoders. The cut density may be improved by eliminating from the bitstream applied to each decoder any data corresponding to bidirectionally compressed images that would otherwise be used by the decoder to generate fields prior to the desired field.Other References
