A system and method for processing thermal signature data is provided. In the electronic trip device, the power supply circuit comprises voltage raising means enabling a raised voltage to be supplied to the input of the voltage regulator designed to supply the supply voltage to the electronic processing unit, said raised voltage being greater than a voltage at the terminals of the storage capacitor. The second acoustic device, when configured using the set of operating parameters, produces an acoustic performance substantially same as that of the first acoustic device. The insert member includes a reduced diameter hub at the bottom end thereof, with a plurality of fingers extending outwardly from the hub. An extension portion is disposed along a sidewall of the hollow body. The clothing assembly comprises an undergarment removably attachable to an upper body garment.
