A method for controlling a gimbal includes detecting a motion of the gimbal, determining whether a received control signal indicates that the motion of the gimbal corresponds to a user-intended motion, controlling the gimbal to move along a moving direction of the motion in response to determining that the received control signal indicates the motion of the gimbal corresponds to the user-intended motion, and controlling the gimbal to move along an opposite direction to the moving direction of the motion in response to determining that the received control signal does not indicate the motion of the gimbal corresponds to the user-intended motion.

A control method for a non-orthogonal gimbal includes obtaining an actual attitude of the gimbal, determining a target attitude of the gimbal according to the actual attitude of the gimbal and an angle between a first rotation axis of a first drive motor and a second rotation axis of a second drive motor, determining an attitude error according to the actual attitude and the target attitude, and controlling one or more of a plurality of drive motors according to the attitude error to cause the gimbal to approach the target attitude. The gimbal includes the plurality of drive motors including the first drive motor, the second drive motor, and the third drive motor. The gimbal further includes a base, a first axis arm, a second axis arm, and a third axis arm.

A mounting assembly includes a mounting block. A first shaft is supported by the mounting block and movable about a first rotational axis of the first shaft and a first extension axis with respect to the mounting block. A clamp is attached to the first shaft, wherein the clamp interfaces with the mounting block to limit movement of the first shaft along the extension axis while allowing rotation of the first shaft about the first rotational axis. A second shaft is coupled to the first shaft and movable about a second rotational axis of the second shaft.

A method for controlling a gimbal includes detecting a motion state of a motion of the gimbal, comparing the motion state to a preset threshold, and controlling the gimbal to move along a moving direction of the motion or to move in an opposite direction to the moving direction oldie motion based on the comparison.

A levelling device for positioning of a medical device in relation to a patient is disclosed. The levelling device comprises a tube having fluid communication between a first end and a second end, wherein the first end is configured for connection to the medical device and the second end is configured for connection to the patient. The levelling device comprises a control unit connected to a sensor, wherein the sensor is configured to transmit sensor data to the control unit which is indicative of a pressure difference between the first and second end of the tube, and an actuator connected to the control unit, wherein the actuator is configured to connect to the medical device and to arrange a position of the medical device in relation to the patient in dependence on said pressure difference.

A system and method for rendering a 3D camera apparatus able to move and rotate as designed, in an upside-down configuration. The system allows for a user to control the camera via the system from above by lowering the camera and system into a manhole or septic tank, allowing a camera to take pictures from the lowest desired point all the way up to the top of the hole.

A dynamic balance type vertical vibration isolator includes slide blocks, balance springs, mass blocks, a fixed block, rotation shafts, stiffness-adjustable springs, etc. When an earthquake force is upward, the stiffness-adjustable springs are compressed, upward forces of the stiffness-adjustable springs are increased, meanwhile, the slide blocks and the mass blocks move away from the fixed block, the balance springs are stretched to generate pull forces, and the pull forces have vertically upward components, so as to reduce compression degrees of the stiffness-adjustable springs, and further to reduce the upward forces of the stiffness-adjustable springs. Similarly, when the earthquake force is downward, the stiffness-adjustable springs are stretched, downward forces of the stiffness-adjustable springs are increased, meanwhile, the slide blocks and the mass blocks move close to the fixed block, the balance springs are compressed to generate compression forces, and the compression forces have vertical downward components.

A decorative stand assembly for combining a terrarium, an aquarium and a waterfall includes a terrarium for housing plant life. The terrarium has a plurality of first windows therein for viewing an interior of the terrarium. A waterfall housing is positioned on the terrarium and the waterfall housing has a plurality of second windows for viewing an interior of the waterfall housing. A pump is positioned within the waterfall housing to pump a fluid into the waterfall housing for simulating a waterfall. An aquarium is coupled to the waterfall housing to house fish.

A system for lowering and guiding a 3D camera apparatus which includes a pole, top mount, at least one cage bar, a base mount and assembly. The system pairs with a 3D camera, keeping the camera safely in place while allowing the camera to move and rotate as designed. The system allows for a user to control the camera via the system from above by lowering the camera and system into a manhole or septic tank, allowing a camera to take pictures from the lowest desired point all the way up to the top of the hole.
