TL;DR: In this article, a multi-dimensional adjusting stereo-shooting dual-position device consisting of a base length adjusting structure, an azimuth angle adjusting structure and a horizontal inclination adjusting structure is presented.
Abstract: The utility model relates to a multi-dimensional adjusting stereoscopic shooting dual-position device which comprises a base length adjusting structure, an azimuth angle adjusting structure, a horizontal inclination angle adjusting structure and a pitch angle adjusting structure. The base length adjusting structure adjusts the space between to sliding blocks through a shaft and enables two cameras to move in the same direction or the reverse directions. The azimuth angle adjusting structure synchronously, equiangularly and reversely rotates a turntable through a shaft and accordingly adjusts the azimuth angle of the two cameras. The horizontal inclination angle adjusting structure adjusts the horizontal inclination angle of a camera, and the pitch angle adjusting structure adjusts the pitch angle of the other camera. The base length adjusting structure and the azimuth angle adjusting structure are independent mutually and respectively control the two cameras to be synchronously and reversely adjusted respectively through the shaft so as to ensure that the symmetric center of the two cameras does not change. Two angular displacement tables are adopted for the horizontal inclination angle adjusting structure and the pitch angle adjusting structure and are arranged on the two turntables in angle rotating direction orthogonality mode, one angular displacement table is used for adjusting the horizontal inclination angle of a camera, and the other angular displacement table is used for adjusting the pitch angle of the other camera. Therefore, stereoscopic effect adjusting and perfect alignment of shot objects at positions of different distances are achieved.

TL;DR: A table system with angular position control is described in this article, in which an object supported on a table can be moved accurately over a tiny angle in circular direction to any desired position.
Abstract: A table system with angular position control means is disclosed in which an object supported on a table can be moved accurately over a tiny angle in circular direction to any desired position. The table(2) is supported on a bed(1) for rotation through a crossed-roller bearing(15). Position control means(3) gets the table(2) to turn over a tiny angle through an arm plate (4) fastened to the table(2). A nut and screw set(10), when driven by a motor(8), causes a linear motion that is in line with a tangent of the table(2), and the linear motion is translated into a circular motion to turn the table(2) in any circular direction by virtue of a combination of a first linear motion guide unit(6) interposed between the bed(1) and a carriage(5) to control the linear motion in the tangential direction, a second bearing means(30) interposed between the carriage(5) and a turret means(25), and a second linear motion guide unit(7) to control a linear motion in the direction that looks towards the center of the table(2).

TL;DR: In this paper, an inertial stabilizing system for image stabilizing of hand-held optical instruments is presented, where an ultralight oscillogro (1-6) serves as a reference element by which the angular position in inertial space is detected.
Abstract: The present invention comprises an inertial stabilizing system to be used preferably in connection with image stabilizing of hand-held optical instruments. An ultralight oscillogyro (1-6) serves as a reference element by which the angular position in inertial space is detected. An electromechanical control system causes a gimbaled part (19) of the optics to assume essentially the same angular position in space assumed by the rotation plane of the rotor of the oscillogyro. The oscillogyro is modified for a widened angular range and the damping of the gyro is utilized for obtaining directly the possibility of target tracking.

TL;DR: In this paper, a rotary actuator is coupled to a base and a displacement member is coupled with an output shaft of the pivot actuator to control the linear position of the displacement member.
Abstract: In a system for controlling the inclination angle and rotation angle of a body, a rotary actuator is coupled to a base. A pivot actuator is coupled to an output shaft of the rotary actuator. The rotary actuator controls the angular position of the pivot actuator. A displacement member is coupled to an output shaft of the pivot actuator. The pivot actuator controls the linear position of the displacement member. A support shaft is pivotably coupled to the displacement member. A spherical bearing includes a socket that is coupled to the base and a ball that is coupled to the support shaft. In this manner, the angular position and linear position of the displacement member is translated to a corresponding rotation angle and inclination angle in the support shaft. This system provides for a continuous range of rotation of the upper body and a continuous range of inclination angles in the upper body relative to the lower base. An optional system for deploying the legs provides for continuous, controlled motion in their release. In doing so, the present invention provides a system with a higher degree of flexibility, precision and reliability.
