Apparatus, systems and methods for removing debris from a surface
View Patent ↗Exemplary surface debris removal systems and methods are operable to remove debris from a signal transmitting/receiving surface. An embodiment provides power to, and then removes power from, a conductive memory wire that is secured to a moveable portion of a two-position snap spring. In response to providing the power to the conductive memory wire, a length of the conductive memory wire decreases so that the moveable portion of the two-position snap spring is pulled from an extended position to a retracted position. When power is removed from the conductive memory wire, the moveable portion of the two-position snap spring moves from the retracted position to the extended position. 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.

a mechanical actuator with a lever arm; and
an electronic actuator coupled to the mechanical actuator, wherein actuation of the electronic actuator causes the lever arm of the mechanical actuator to engage the moveable portion of the mechanical system, and where in response to engaging the lever arm, the moveable portion of the mechanical system moves from the retracted position to the extended position,
where in response to the moving of the moveable portion from the retracted position to the extended position, an energy is generated and transferred to the surface that dislodges the debris from the surface.

a mechanical actuator with a lever arm configured to engage the moveable portion of the two-position snap spring;
an electronic actuator coupled to the mechanical actuator, wherein actuation of the electronic actuator causes the lever arm of the mechanical actuator to release the moveable portion of the two-position snap spring from the retracted position to the extended position, where in response to the movement of the moveable portion of the two-position snap spring from the retracted position to the extended position, an energy is generated and transferred from the moveable portion of the two-position snap spring to a surface having debris thereon.
