Assignee:

inTest IP Corp. - Wilmington DE

International Classification:

G01R 3102

US Classification:

324758, 324754

Abstract:

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 support structure for moving the test head along a second axis orthogonal to the first axis. The support structure accurately docks the electronic test head with the device handler.

US Classification:

3241581, 324758, 414589

Abstract:

A safety lock system prevents unlocking of a balanced loaded unit when the loaded unit becomes unbalanced. A plurality of calipers applies pressure on opposite sides of a guide rail. A lock block couples the load to at least one of the calipers for movement of the load along the guide rail. A rotatable handle is coupled to the calipers through a shaft. Rotation of the handle locks or unlocks the lock block against vertical movement. A safety block is coupled to the loaded unit and is moveable with the loaded unit for preventing rotation of the handle upon a preselected movement of the loaded unit relative to the lock block.
