Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
128 words
Apparatus for deflecting light in response to electromagnetic signals, comprising, in combination: movable transducer means for converting electrical signals into magnetic pulses, including a winding for transmitting electrical signals, and a core disposed in the winding and linearly movable in response to the electrical signals in the coil; support means secured to the core and movable therewith, including a plurality of posts secured to the core and a plurality of tension springs, including a tension spring secured to each post; a mass secured to the plurality of the posts of the support means by the tension springs and movable in a nonlinear manner in response to the movement of the core and the support means; and a mirror secured to the mass and movable therewith to deflect light.
Claim 2
Dependent Claim
