A server is configured to store a number of different models of an object in machine-ready form corresponding to a number of different three-dimensional printers having differing capabilities and/or hardware configurations. When a user at a client device or a printer requests the object, the server automatically determines a printer type and selects a suitable, corresponding machine-ready model for immediate fabrication by the printer.

A multi-axis positioning stage or positioner includes a top plate supported and manipulatable by a plurality of prismatic joint actuators. Each actuator includes an actuator joint having four or five Degrees of Freedom (DOF) with the top plate. When one or more of the actuators extends or contracts, the pivot points, or four or five DOF actuator joints, of the remaining actuators are allowed to shift to move the top plate. The actuators can be disposed between at least one base plate or base structure, and can be fixed thereto.

A rotary stage assembly includes a platform and a rotary drive defining an axis of rotation. The platform is mounted on a spindle for receiving rotary movement from the rotary drive. A cylindrical wall is attached to the platform receiving rotary movement from the rotary drive and is coaxial with the axis of rotation defined by the rotary drive. The cylindrical wall defines an inner surface including reference patterns. An imaging assembly images the reference patterns on the inner surface of the cylindrical wall. The imaging assembly detects angular orientation and tilt of the platform from an axis of rotation of the platform from imaging the reference patterns on the inner surface of the cylindrical wall. A controller calculates angular orientation and tilt of the platform from the location of said reference patterns signaled from the imaging assembly.

Methods, apparatus, systems and articles of manufacture are disclosed to mount a camera to a mounting plate, the apparatus comprising: a camera socket connector to connect to a socket of the camera; and a mounting plate connector to connect to the mounting plate, wherein the camera socket connector able to be removably coupled to the mounting plate connector.

A self-balancing vibration damping system, an active vibration damping seat, and transport equipment are provided. The self-balancing vibration damping system includes an active vibration damping module, a control module, a sensor module, and a receiving module, where the sensor module is configured to acquire motion data of the transport equipment; the active vibration damping module includes a first rotating assembly and a second rotating assembly; the first rotating assembly is provided in an accommodation space; the second rotating assembly is provided at a driving end of the first rotating assembly, and is butted with the receiving module; the control module is configured to control the first rotating assembly and the second rotating assembly to operate synchronously according to the motion data, so as to provide a force opposite to a tilt direction of the receiving module.

An apparatus is provided comprising a shaft having an axis and mounted to a boom structure, a support structure configured to be coupled to the shaft, wherein the support structure is configured to rotate about the axis. In addition, a method is provided comprising translating a cradle along a vertical axis, and rotating, in response to the translating, a support structure about a shaft, wherein the cradle is supported by the support structure, wherein the cradle remains stationary with regard to pitch rotation during the translating.

One or more embodiments for a rotating mounting header are adapted to connect to a single stand and provide options for connecting to a number of equipment, either type and/or amount, on a single rotating and mounting header. The rotating mounting header provides the variety of options by providing an option for including a various number of arms and/or various types of arms to connect to and extend out from a center column. The rotating mounting header comprises a center column that can accommodate a various configurations of arm mounting cylinders such that one or more arms can connect to the rotating mounting header assembly at the same time, and the one or more arms are further able to rotate simultaneously or freely move independent of another arm at the center column while also being set at a same level plane.
