A lateral, high-voltage, FET having a low on-resistance and a buried conduction layer comprises a P-type buried layer region within an N-well formed in a P-type substrate. The loop portion includes a support and a loop material disposed on one side thereof whereas the hook portion includes a support and a plurality of closely spaced upstanding hook elements extending from one side thereof. Thus said combustion air at the air inlet to said gas turbine obtains a lowered temperature and increases an efficiency of said gas turbine. The egress network receives the packetized voice signal, converts the packetized voice signal into an output voice signal, and outputs the output voice signal. The light unit control circuit includes a timer configured to cause the light unit to illuminate a first brightness level when the switch unit is actuated, and to remain illuminated at the first brightness level for a predetermined time period after the trigger is actuated.
