Patent ID: 8325408

Claim:
A device comprising an electromechanical shutter device comprising a base member and a shutter assembly associated with the base member, the shutter assembly comprising: an electrical current source member associated with the base member; a shutter member spaced apart from and movable with respect to the electrical current source member between a light beam blocked position and a light beam passed position; a light beam blocking member associated with the shutter member for blocking a light beam when the shutter member is moved to the light beam blocked position and for not blocking the light beam when the shutter member is moved to the light beam passed position; a shutter coil associated with the shutter member which generates an electromagnetic force when energized; at least one magnet positioned proximate to the shutter coil and which generates a magnetic flux directed towards and intersecting the shutter coil; electrically conductive means connecting the electrical current source member to the shutter member for passing electrical current from the electrical current source member to the shutter member to energize the shutter coil and to control movement of the shutter member between the light beam blocked position and the light beam passed position; wherein when the shutter coil is energized, an electromagnetic force is generated by the shutter coil which interacts with the magnetic flux to thereby cause movement of the shutter member between the light beam blocked position and the light beam passed position; wherein the electrical current source member comprises a stationary printed circuit board and wherein the shutter member comprises a printed circuit board movable vertically between the light beam blocked position and the light beam passed position, wherein the shutter coil is formed into the shutter member, wherein the shutter member has a pair of opposite sides, and wherein the shutter coil comprises a first shutter coil formed in one side, and a second shutter coil formed in the other side, wherein the first and second shutter coils are connected in series.
