  • System and method for continuously adaptive indexes
    Patent number: 6360213
    Abstract: Hybrid target indexes are employed for skewed data set domains. Such hybrid indexes contain multiple value representations within a given index. The representations can be optimized for particular keys in highly skewed data set domains. For example, a hybrid target index on customer states might employ a bitmap to represent the index value for a California key and also employ, in the same index, an uncompressed list of row-IDs to represent the index value for a Delaware key.

  • Gas tight tank cleaning method
    Patent number: 5776257
    Abstract: Methods for cleaning industrial tanks are disclosed in which a fast temporary seal is applied to a manway entry into a tank to be cleaned. A robotic tank cleaning system is introduced through the temporary seal into the tank.
