摘要： A camera apparatus capable of providing optical image stabilization comprises: a support structure; a camera unit comprising an image sensor and a lens system; a suspension system comprising a plurality of flexure elements supporting the camera unit on the support structure in a manner allowing the camera unit to tilt; and a plurality of SMA actuators. A sensor arrangement, whose output is used as the basis for generating drive signals, is mounted on the camera unit. A control circuit generates drive signals for the SMA actuators, by deriving closed-loop control signals representative of a desired degree of variation in the power of the drive signals from the output signals of the sensor arrangement without dependence on any measurement of the resistance of the SMA actuators, and generating the drive signals with powers that varies from a set-point power in correspondence with the closed-loop control signal.

摘要： In a camera apparatus, two SMA actuator subsystems each comprise two SMA wires connected between a camera unit and a support structure, hooked over a pivot element defining pivot axes that lie in a common plane along the optical axis. Differential contraction of the SMA wires drives rotation. The SMA actuator subsystems are opposed, but the SMA wires of each subsystem are fixed respectively to the camera unit and the support structure, reducing the height. A non-conductive substrate supporting conductive tracks electrically connected to the SMA actuator system is configured as a flexure arrangement between the camera unit and the support structure. The flexure arrangement is connected to the camera unit at a position in the common plane reducing lateral resistance to tilt. Use of an intermediate connector element allows the circuit board to be arranged in front of the intermediate connector inside the height of the lens system.

摘要： A shape memory alloy actuation apparatus comprises a camera lens element supported on the support structure by a plurality of resilient flexures that guide movement of the movable element along the optical axis. A shape memory alloy actuator biassed by the resilient flexures and an additional resilient biassing element is arranged to drive movement of the camera lens element. An end-stop limits movement of the camera lens element at a position where the shape memory alloy actuator has a predetermined length that is above the length corresponding on the local maximum resistance by an amount not greater than 15% of the difference between (i) the length corresponding to the local maximum resistance and (ii) the length corresponding to the local minimum resistance.

摘要： A miniature camera lens actuation apparatus employs an SMA actuator comprising SMA wire to move a camera lens element. To provide autofocus, the SMA actuator is heated across its range of contraction and the resistance at which the focus is at an acceptable level is stored. To combat hysteresis, there is performed a flyback in which the SMA actuator is cooled, before heating the SMA actuator to the stored resistance. The stored resistance is adjusted to combat creep caused by non-linear heating of the SMA actuator. The SMA wire has conductive material extending along on a portion of the SMA wire which extends from a member connected to the SMA wire and being in electrical connection with the SMA wire in order to short out that portion of the SMA wire to reduce creep. Additional material is applied over the SMA wire and the member to reduce fatigue.

摘要： A piezoelectric device comprising a continuous piezoelectric element (10) extending alternately back and forth to form a plurality of parallel, straight portions (14) arranged in a stack with intermediate linkage portions (15) at alternate ends the straight portions (14). Each straight portion (14) is constructed and arranged with electrodes (12, 13) to bend, on activation, in the stacking direction in which the straight portions (14) are stacked with opposite curvature in two halves (16, 17) of the straight portion (14) to create displacement between the ends of the straight portion (14) in the stacking direction adding in series through the stack. The continuous nature of the piezoelectric element (10) eases manufacture. Devices with two types of construction are disclosed. Firstly, the continuous piezoelectric element (10) may have a bender construction such as a bimorph bender construction. Secondly, the continuous piezoelectric element (101) may be a sheet of piezoelectric material having overlapping slits (102) extending from alternate sides to form the straight portions (103) between the slits (102), with opposed electrodes (105) arranged on each major surface of the sheet in pairs separated across, and extending along, the straight portions (103).
