The present invention relates to a resetable over-current protection device. A waterproof housing has a mounting mechanism to engage a part of a headgear worn by an operator to position the housing in a portion of the operator’s forward field of view. A tunneling metal-insulator-metal capacitor is created between the control gate and a writeerase bit line. The first pump assembly includes a piston having a first end, a second end, and a throughbore extending between the first end and the second end. The resultant data is subjected to decoding and analog conversion to be converted into an audio signal.
