Systems and methods for selectively disabling electrical and mechanical devices

A motor override system including:

• a structure responsive to an energy wave for changing a state of a mechanism to which the structure is operatively coupled, the structure including a material selectively changeable upon exposure to the energy wave to cause at least a portion of the material to degrade from a first state to a second state;
• a signal receiving device on an exterior surface of a housing encasing the engine;
• a signal receiving device in communication with the signal receiving device that receives a signal and transmits the signal to the structure,
• wherein, when the material is in the first state and the material forms a mechanical or electrical link with the mechanism such that a force can be transmitted through the material,
• when the material is in the second state, the degradation of at least the portion of the material disrupts the mechanical or electrical link and inhibits transmission of the force through the material causing a change in the state of the mechanism,
• when the material is in the second state, electrical power to the engine is stopped thereby stopping the operation of the engine.
