In accordance with the present invention, an information management application that provides users with the ability to create and customize matrix displays of information relating to a particular product or service for navigation by other users is provided. The invention includes modifying a first test mode of a plurality of latches included in a scan chain, operating the latches in the modified first test mode, and operating the plurality of latches included in the scan chain in a second test mode. The primary seal assembly includes an annular seal ring and an arcuate support arm. The plunger has a handle disposed at a top end and a working end in the shape of a ball, disposed at its lower end. The elastic element is resisted between the housing and the latching element, the elastic element is used for accumulating an elastic force with rotation of the stylus body relative to the housing and the movement of the latching element. This process may be continued for two or more iterations to obtain better interference cancellation.
