  • Patent number: 8593568
    Abstract: A shape memory alloy actuation apparatus comprises a movable element supported on a support structure by a suspension system comprising a plurality of resilient flexures. A shape memory alloy actuator drives movement of the movable element on contraction. An end-stop limits the movement of the movable element in the opposite direction. Rather than using the resilient flexures of the suspension system as the sole biassing means, an additional Massing element biasses the movable element against the SMA actuator. When the moveable element is held against the end-stop, the force applied by the biassing element is greater than the force applied by the flexures of the suspension system. This reduces the design constraints, for example allowing a greater range of movement.

  • Patent number: 8023813
    Abstract: A collapsible lens barrel includes a first holding frame (2) for holding a first lens group (L1), a second holding frame (5) for holding a second lens group (L2) that is disposed on an image plane side with respect to the first lens group (L1), an actuator (6) for moving the second holding frame 5 in an optical axis direction, and a tubular cam frame (17) including a plurality of cam grooves that are formed at substantially equal intervals around a circumferential direction for moving the first holding frame (2) in the optical axis direction. The actuator (6) is attached to a portion in the cam frame (17) where the cam grooves are not formed. The first lens group (L1) is moved using the cam grooves, and the second lens group (L2) is moved using the actuator (6), so that a faster zooming speed and a lower zooming noise can be achieved.

  • Patent number: 7965934
    Abstract: A switching mechanism for a camera device includes a driving device, a first screw bar connecting to the driving device, a second screw bar connecting to the first screw bar, and a lead screw having an end coupled with the second screw bar. The first screw bar is driven by the driving device via a screw thread thereof, and the second screw bar is driven by the first screw bar via a screw thread thereof, thereby driving the lead screw for rotation. The screw nut is disposed on the lead screw and moved back and forth via the rotation of the lead screw. Two stop blocks disposed at two ends of the lead screw respectively are to limit two positions of the moved screw nut while the screw nut is moved beyond a threaded area of the lead screw, upon which time the screw nut is slightly engaged with the lead screw.
