An adaptable camera support includes a quick disconnect, panning ball clamp connectable to an adjustable clamp. The relative angularity and separation of the jaws of the adjustable clamp are independently variable to engage articles of widely varying size and shape. The quick disconnect panning ball clamp includes a rotatable panning base and a ball element rotatable on axes at an angle to the axis of rotation of the panning base. Hinged ball clamp housing sections enable rapid releasing and securing of the ball element and an article attached to the ball element.

An improved antenna ball joint mount is provided that includes a hollow socket mechanically coupled to a spherical member with a locking part. The hollow socket and the spherical member are fully detachable to simplify the installation of an antenna. A user is able to set a position of the antenna to any point on a spherical sector surface within a range of motion allowed by a shape of joint components and rotate the antenna around own axis to adjust a polarization plane and then lock the mount in a predetermined position.

A joint having a base portion, an upper portion, and an actuation portion. The base portion defines a socket. The upper portion has a spherical element at least partially located inside the socket, and the spherical element defines a locking portion. The actuation portion is at least partially located inside the base portion. The actuation portion has a button, a button spring, a pin, a pin spring. The button defines a pin receiving space. The pin has a pin projection, and the pin extends through the pin receiving space. The button is configured to move between a locked position, in which the pin is prevented from moving in an actuation direction, and an actuation position, in which the pin is capable of at least some movement in the actuation direction. The button spring biases the button to the locked position, and the pin spring biases the pin toward the spherical element and abuts the locking portion. In the actuation position, the upper portion is able to move within the socket while the pin projection abuts the spherical element, and the pin is able to move in the actuation direction. In the locked position, the button prevents the pin from moving in the actuation direction, and the pin projection is located inside the locking portion.

A slim type universal joint is used to transmit torque generated by an output/driving shaft and/or rotary motion on a rotation axis on a system of engine vehicles connected thereto into the output/driving shaft of a different axis and allows independent locking of the rotation axis. The slim type universal joint includes a locking hole, a central-lower part, a central-upper part, pin holes, an outer-lower part and an outer-upper part, a first short cap pin, a second short cap pin and a long cap pin.

A rotational degree of freedom joint constraint system is disclosed. The system can include joint constraint hardware, such as a first component and a second component. The first component can have a rotational interface, and a constraint feature associated with the rotational interface. The second component can have a socket operable with the rotational interface to facilitate relative movement of the first component and the second component in at least one rotational degree of freedom. The second component can form an opening configured to facilitate movement of the constraint feature therein upon the relative movement of the first component and the second component. The rotational degree of freedom joint constraint system can also include a locking mechanism operable with the constraint feature. Movement of the constraint feature within the opening can be preventable by the locking mechanism to constrain the relative movement of the first component and the second component.

A multi-joint fixture including a proximal base unit, one or more arms serially connected by electromagnetically lockable ball joints, and a distal hub. The ball joints unlock when not powered. A centering mechanism biases the ball joints toward a neutral position. A control system activates the electromagnetic brake with a high-then-low voltage profile. A headpiece attaches to the hub and holds a drape that covers the fixture. A connector connects a surgical device to the headpiece. A switch on the hub can be actuated via actuators on the headpiece or connector.

A resonance testing apparatus has a plurality of arms for supporting a workpiece. At least one of said arms incorporates an articulation assembly having: a strut, a joint element which is movable in response to movement of the strut, and a clamp arrangement for clamping the joint element. The assembly has a first condition in which the joint element is movable and a second condition in which the clamp arrangement acts on the joint element to damp or restrict movement of the strut. The assembly includes a seating for the joint element, and a biasing arrangement for the seating. The assembly has a first condition in which the joint element is arranged on the seating and is movable on the seating and a second condition in which the biasing arrangement acts on the seating to damp or restrict movement of the joint element on the seating.

A pivoting joint assembly includes a base, a plate, and at least one bolt. The base has one or more semi-spherical sockets with each socket having a centrally-positioned hole extending through the base. The plate has one or more semi-spherical sockets recessed within the plate with aligned semi-spherical protrusions extending from the plate. The plate has a hole extending through a central portion of each of the plate's sockets and a corresponding protrusion aligned therewith. Each protrusion is partially fitted in a corresponding socket in the base. Each bolt has a head and a post extending from the head. The head includes a semi-spherical portion adjacent to the post. The post extends through aligned holes in the plate and base. The post is coupled to the base such that the semi-spherical portion of bolt's head nests within one of the plate's sockets.
