A safety lock comprises a locking member () which engages a support. An inner lock shaft () actuates the locking member, the inner lock shaft having a first coupling face () at one end thereof. An outer lock shaft () has a second coupling face () which engages the first coupling face when the inner lock shaft and the outer lock shaft are in respective engagement positions relative to each other. A coupling structure () moves to prevent engagement of said first coupling face with said second coupling face.

Safety mechanism for materials handling system

A positioner facilitates docking and undocking of an electronic test head with a device handler. The positioner provides for rotation of the test head about a first axis. The positioner includes a linkage arm structure for moving the test head along a second axis orthogonal to the first axis. Using motors, sensors and a processor, the linkage arm structure accurately docks the electronic test head with the device handler.

Method and apparatus for automated docking of a test head to a device

A positioner facilitates docking and undocking of an electronic test head with a device handler. The position provides for rotation of the test head about a first axis. The positioner includes a scissor arm structure for moving the test head along a second axis orthogonal to the first axis

Electronic test head manipulator

A device testing system of the type in which an electronic test head is mounted for pivotal movement about three orthogonal axes. Cables are connected between a test cabinet and the test head to carry electronic signals. The test head is directly mounted to, and the cable is introduced to the test head through, a split ring cable pivot.

Device testing system with cable pivot

A materials handling system in which a load is maintained in a substantially weightless condition for easy and accurate positioning. A safety lock is introduced to prevent unlocking of the system if a condition of imbalance takes place while the system is locked.
