| 20100119222 | ELECTROMAGNETIC SHUTTER FOR IMAGING SENSORS - A shutter mechanism for an optical system includes a linear track having a first end and a second end, a first magnetic assembly located adjacent the first end of the track and a second magnetic assembly located adjacent the second end of the track, the two magnetic assemblies arranged in opposite polarities. A shutter plate is provided coupled to a coil mounted on and movable across the track. When a direct electric current is passed through the coil in one direction the shutter is forced to move to the first end of the track, whereas when a direct electric current is passed through the coil in an opposite direction the shutter is forced to move to the second end of the track. | 05-13-2010 |
