Abstract:
A controllable deflection device comprising:a first electromagnet supported by a first deflection element; a second electromagnet supported by a second deflection element spaced apart from said first deflection element; a first manipulatable element coupled with said first deflection element; and a second manipulatable element coupled with said second deflection element; and wherein said first electromagnet is juxtaposed to said second electromagnet so as to provide mutual magnetic attraction between said first and second electromagnets in response to controlled current flow therethrough, and thereby a controlled reduction in physical separation between said first and second electromagnets, and between said first and second manipulatable elements against a spring force of said first and second deflection elements, allowing said spring force of said first and second deflection elements to diminish said reduction in physical separation between said first and second electromagnets and said first and second manipulatable elements, for a prescribed reduction in said current flow.
