An automated analysis system identifies the presence of malicious P-code or N-code programs in a manner that limits the possibility of the malicious code infecting a target computer. At least a portion of a plurality of transport packets stored in a buffer include a first timestamp value. A plurality of emergency signaling devices transmit digital radio signals on the channels of frequencies reserved for public safety personnel to the light assemblies to transmit a radio signal on the reserved frequencies to the central transceiver, a 9-1-1 alert or the like. In an exemplary embodiment of the present invention, a driver circuit includes switching circuitry connected between the terminals of the write head and reference voltage supplies, such as positive and negative voltage supplies. In one embodiment, the method of manufacturing the gate dielectric includes forming a gate dielectric layer on a substrate, and subjecting the gate dielectric layer to a nitrogen containing plasma process, wherein the nitrogen containing plasma process has a ratio of helium to nitrogen of 3:1 or greater.
