A device can include a processor; memory; a display; a bezel that defines a bezel region and a display region for the display; one or more media capture components where the one or more media capture components include a camera operatively coupled to the processor, where the camera includes an aperture disposed in the bezel region; a switch that includes an operational state for a circuit electrically coupled to the at least one of the one or more media capture components and a nonoperational state for the circuit; and a movable shutter that controls the switch, where the movable shutter includes a closed orientation that obscures a field of view of the camera and that corresponds to the nonoperational state of the switch and an open orientation that does not obscure the field of view and that corresponds to the operational state of the switch.

A shutter device includes a light blocking unit and a voice coil motor. The voice coil motor includes a permanent magnet module, a guide track assembly and a coil assembly. The coil assembly is arranged on the guide track assembly, and the permanent magnet module is adapted to produce a magnetic field in the guide track assembly. The light blocking unit includes two shutter blades both connecting to the coil assembly. When energized, the coil assembly will produce a magnetic field having a direction same as or opposite to the direction of the magnetic field in the guide track assembly so that the coil assembly moves forward or backward along the guide track assembly to drive the two shutter blades to open or close. A method controls the shutter device. An exposure dose control method is used with a photolithography machine including the shutter device.

An optical system is provided and includes a fixed assembly, a movable member, a driving assembly and a buffering member. The movable member is movably connected to the fixed assembly and is configured to hold an optical member having an optical axis. The driving assembly is for driving the movable member to move relative to the fixed assembly. The buffering member is disposed on a first surface of the fixed assembly. The buffering member, the movable member and the fixed assembly are arranged along the optical axis. The buffering member includes a soft resin material. The buffering member is disposed to surround the optical axis.
