    Abstract: A toe-in system allows for electromechanical control to adjust the parallax, or "toe-in", of two cameras to create an accurately fused 3D stereoscopic image. The system includes of two cameras, an electromechanical adjustment mechanism, an electronic method of distance measurement, image processing software, and a correlation algorithm. The two cameras are to be mounted equidistant from the center axis of the device, with the electromechanical control method attached to each camera independently, or dependently. The cameras may be mounted in a manner that allows for restricted movement by the electromechanical drive mechanism. The electronic distance measurement sensor measures the distance from the objective to the cameras image capturing sensor or center of rotation. With the distance and the kinematic parameters of the electromechanical drive method being known, a correlation algorithm calculates the required quantity of "toe-in" needed to create a fused, stereoscopic, 3D, image.

    Abstract: The present invention relates to an actuator (5) comprising a driving device (15) adapted to move a spindle (20) in first and second rotational directions (200), where the spindle (20) is connected to a nut (25) such that when the spindle (20) rotates the nut (25) is translocated in a third or fourth translational direction (210), where the movement of the nut (25) acts on a deformable part (30), such that the translocation of the nut (25) is reflected in a deformation of the deformable part (30). The deformable part (30) is deformed into a hollow (35) formed between the driving device (15) and the deformable part (30), and the spindle (20) reaches through the deformable part (30) and the hollow (35).
