Apple has been granted patents for a variety of items, including the design of the original iPod and iPod touch. Summaries of each are below.
Patent number 7782337 involves multi-conic gradient generation. Disclosed is a technique for computing a complex gradient using multiple conics. In connection with a computer system having a graphics processing unit (GPU) in addition to the normal central processing unit (CPU), gradients can be computed in real time. The conics may be rendered and adjusted in a number of ways, providing a rich palette for creation of gradient graphics. The computational efficiency of the algorithms disclosed herein, when executed on typical GPU hardware, allows rendering frame rates high enough to provide animated gradient images. The inventors are Mark Zimmer and Ralph Brunner.
Patent number 7783589 is for inverted index processing. Systems and methods for improving indexing are described. In one exemplary...| Read more »
