摘要： The invention relates in general to the field of digital cameras, especially small digital cameras. In particularly the invention relates for adjusting an aperture for mobile cameras. The adjustable aperture construction of the invention comprises two electrodes, and an electrical circuit for applying a voltage to the electrodes in order to create an electric field between the electrodes. In addition the construction comprises between the electrodes a center unit with a hole in the middle of it, the center unit being made of an electroactive material, such as dielectric material or electrostrictive polymer. The aperture can be adjusted by deforming the shape of the center unit. The shape of the center unit is advantageously deformed by the electric field created between said electrodes by said electrical circuit.

摘要： To control an electromechanical actuator in a camera from a digital computer without an expensive digital-to-analog conversion device, a series of electrical pulses are created and the duty cycle is varied in accordance with the computer output. The resulting signal is then applied to an electromechanical actuator which responds to the average current of the signal.
An actuator controllable by such a method is of the type having a planar coil (22) mounted on an armature (20) for rotation in the plane of the coil. To reduce friction and reduce parts, the armature (20) is mounted on a flexure spring (26) which urges the armature (20) toward its initial position.

摘要： A motor driving apparatus includes a power circuit that controls an output voltage via a feedback resistance (1-16, 1-17, 1-18). The power circuit varies the output voltage by changing a value of the feedback resistance (1-16, 1-17, 1-18) at a time of at least one of activation and termination of a motor (204, 205, 206, 210), thereby enabling to activate the motor (204, 205, 206, 210) at any one of a high speed and a low speed.
