An amplifier capable of lowering an electrical current flowing in a peak amplifier before a carrier amplifier becomes saturated to thereby improve the efficiency of an entirety of the amplifier is provided. Detection of the grace period includes establishing a token to be circulated between processing entities sharing access to the data element. The method includes the steps of: providing a case made of thermoplastic doped with organometallic additive; activating the organometallic additive in the case by a laser beam for forming initial pattern of the hearing aid coil in the inner surface of the case; and bathing the case in copper solution for providing the initial pattern with copper plating layer. Moreover, the collected and analyzed information can be used to identify and resolve problems in the wireless network, especially when the identified problems are correlating with E911 location information.
