The present invention relates to a method and system for the automated construction of application signatures. The arc extinguishing chamber has a plate-shaped fixed contact support insulating substrate including through holes to fix at least the pair of fixed contacts and formed with a metal foil on an outer peripheral circumferential edge of one surface by a metalizing process. If the cellular phone and the receiver would become disassociated more than a specified number of feet, the receiver would notify the individual of this fact so that the cellular phone could be retrieved, if necessary. The aspect of the game object’s trajectory may occur according to a known probability.
