A Sort-on-the-FlySearch-on-the-Fly search engine provides an intuitive mechanisms for searching databases, allowing a user to access data in the database without having to know anything about the database structure. For each sample in each of the block of data in the received frame, a corresponding one of the diversity combining weight vectors may be applied to extract a corresponding logic level. In addition, the composition of the present invention is very noncaustic to skin, even when employed at a pH as low as 0.
