Abstract
A method of controlling a plurality of shutter blades includes providing a shutter assembly including a solenoid having a first magnetic pole, a second magnetic pole, and a gap between the first and second poles. The shutter assembly also includes a permanent magnet moveable within the gap in a path coplanar with the solenoid, wherein movement of the permanent magnet transitions the plurality of shutter blades between an open position exposing a central opening of the shutter assembly and a closed position. The method also includes moving the plurality of shutter blades between the open and closed positions, and reducing an electrical signal applied to the solenoid while the plurality of shutter blades is in transit between the open and closed positions.
