Shutter assembly for managing light relative to a photosensitive device

A photosensor assembly operable with a shutter assembly, comprising:

• a photosensor platform;
• a photosensitive device coupled to the photosensor platform;
• a shutter assembly comprising:
• a base coupled to the photosensor platform;
• a flexure device supported by the base, the flexure device having a flexible member;
• a shutter arm rotatably coupled to the base via the flexure device;
• and
• an actuation mechanism coupled to the shutter arm via the flexure device, the actuation mechanism operable, upon application of an electric field, to rotate the shutter arm from a first position to a second position to manage light relative to the photosensitive device,
• wherein, upon rotation of the shutter arm to the second position, the flexible member bends and stores energy, and wherein, upon removal of the electric field, the flexible member releases the stored energy to return the shutter arm to the first position.

A method for operating a shutter assembly to manage light relative to a photosensitive device, comprising:

• applying a first electric field to an actuation mechanism to move a shutter arm from a first position to a second position, a flexure device storing energy due to bending of a flexible member upon the shutter arm moving to the second position, the shutter arm being maintained in the second position by a keeper magnet coupled to a ferromagnetic component by a magnetic force;
• facilitating removal of the first electric field from the actuation mechanism, whereby the magnet force maintains the shutter arm in the second position;
• and
• applying a second electric field to the actuation mechanism that causes an actuation force that overcomes the magnetic force, wherein upon overcoming the magnetic force, the flexure device releasing the stored energy from the flexible member to move the shutter arm to the first position.
