10 results about "Translational motion" patented technology

Methods and systems are provided for nautical stationkeeping of free-floating objects. In one example, a method includes adjusting translational motion of a body freely floating in water by rotating the body. The translational motion may be adjusted, for instance, to maintain the body within a geographic area. In certain examples, the adjustment of the translational motion may be realized via a Magnus effect induced by rotating the body. The body may be configured as, for example, a free-floating object such as a wave engine.

The invention relates to an ultrasonic inspection system (600) designed for the automated non-destructive testing of large composite structures, particularly in the aerospace industry. Traditional ultrasonic inspection requires precise probe positioning, which can be affected by discrepancies between the CAD model used for programming and the actual part. The proposed system includes a probe holder moved by an end effector (650), ensuring constant alignment of the ultrasonic probe (150) despite these discrepancies. The probe holder incorporates a dual compliance mechanism: an upper system allowing limited translational movement with elastic return to maintain alignment, and a lower system providing angular adjustments via two intersecting axes of rotation. Rolling elements ensure a constant distance and orientation between the ultrasonic probe and the surface to be inspected.Adapted to complex geometries, this system allows reliable automated ultrasonic control, compensating for positioning variations, thus improving the accuracy and repeatability of defect detection Figure 6.

The invention provides a bending actuation type four-degree-of-freedom micro-motion platform with double piezoelectric actuators and an excitation method of the bending actuation type four-degree-of-freedom micro-motion platform, and belongs to the technical field of image stabilization and vibration suppression platforms. The micro-motion platform comprises a tail end platform, eight first bolts, two flexible hinges, two amplitude-change poles, four strain gauges, two piezoelectric actuators, two second bolts and a base; all the components are fixedly connected through the first bolt and the second bolt; the flexible hinge is used for transmitting linear and bending motion, and the piezoelectric actuator can achieve displacement output in a bending mode in the up-down direction and the left-right direction under the control of two paths of voltage. By coordinating the bending directions of the two piezoelectric actuators, the tail end platform can achieve translational motion along the Y axis and the Z axis and rotational motion around the Y axis and the Z axis, and therefore four-degree-of-freedom precise micro-motion adjustment is completed. The invention has the advantages of compact structure, small number of drivers, fast response and high precision, and is suitable for aerospace, navigation and other application scenes with strict requirements on optical imaging stability.

A dispensing head for a fluid product is adapted to mount on a fluid product reservoir of a dispenser. The dispensing head includes a pump actuator, and a locking system. The pump actuator is capable of moving along a main longitudinal axis (X) from a rest position to a product dispensing position, and vice versa. The locking system for the actuator enables the actuator to be locked and / or unlocked. The locking system include an actuating means and a ring. The actuating means is capable of moving in a translational movement in a plane perpendicular to the main axis (X) from a locking position of the actuator to an unlocking position of the actuator, and vice versa. The ring capable of moving in a rotational movement about the main axis.
