Patent ID: 8282740

Claim:
A method for debris removal from a surface, the method comprising: providing power to a conductive memory wire that is secured to a moveable portion of a two-position snap spring, where in response to providing the power to the conductive memory wire, a length of the conductive memory wire decreases, and where in response to the decreasing length of the conductive memory wire, the moveable portion of the two-position snap spring is pulled from an extended position to a retracted position; and removing power from the conductive memory wire, where in response to removing the power to the conductive memory wire, the moveable portion of the two-position snap spring moves from the retracted position to the extended position, and where in response to the moving of the moveable portion of the two-position snap spring from the retracted position to the extended position, an energy is generated and transferred to the surface that dislodges the debris from the surface.
