...that after Parker Brothers executives turned down the game of Monopoly because it had "52 fundamental errors" (including taking too long to play), a copy of the game wound up in the home of the company president who stayed up until 1 a.m. to finish playing it? He was so impressed by the game that the next day he wrote to inventor Charles Darrow and offered to buy it!

| 7728880 | Automatic white balance method and apparatus Automatic white balance of captured images can be performed based on a gray world assumption. Initially, a flat field gray image is captured for one or more reference illuminations. The statistics of the captured gray image are determined and stored for each referen... | 06/01/2010 |
| 7702169 | Systems, methods, and apparatus for table construction and use in image processing A method of processing an image includes selecting, for each of a plurality of picture element values in at least a portion of the image, one among a plurality of offset values. For each of the plurality of picture element values, an index value is obtained based on... | 04/20/2010 |
| 7698132 | Sub-sampled excitation waveform codebooks Methods and apparatus are presented for reducing the number of bits needed to represent an excitation waveform. An acoustic signal in an analysis frame is analyzed to determine whether it is a band-limited signal. A sub-sampled sparse codebook is used to generate th... | 04/13/2010 |
