Abstract: A method for powering down a autonomous power unit includes a spark ignition engine power source having an associated power source actuating system and a power output, comprises a regulator associated with the power source. The regulator comprises a deactivator actuatingly linked to the power source actuating system and having a base and secondary configurations wherein the base configuration allows the rated power output by the power source and the secondary configurations allow a progressively reduced secondary rate of power output by the power source and wherein the secondary rates are less than the base rate. The apparatus further comprises a controller remote from the regulator, for transmitting a control signal to the regulator. The deactivator is actuable in response to the control signal to activate either the base rate configuration or one of the secondary configurations to control thereby regulating the power source.

Abstract: An apparatus is disclosed for remotely and controllably deactivating or partly deactivating a first asset, which first asset may comprise an air dependent power source. The apparatus may comprise a regulator associated with the first asset. The regulator may comprise a valve having first and second positions and the first position may allow a first rate of the air supply to the power source and the second position may allow a second rate of air supply to the power source and the second rate may be less than the first rate. The apparatus may further comprise a controller remote from the regulator for transmitting a control signal to the regulator; the valve being actuable in response to the control signal to move between the first and second positions thereby regulating the air supply to the power source.
