Abstract: A keying mechanism within a device bay allows a device connector of a device to make electrical connection with the device bay connector when a key slot of the device is located in one of a plurality of predetermined locations on the device. The keying mechanism prevents the device connector from making electrical connection with the device bay connector when the device does not have a key slot in any of the predetermined locations.

Abstract: Apparatuses and methods for supporting a receptacle block in a device testing a unit under test. The unit under test includes the receptacle block, which has one or more receptacles electrically coupled to components of the unit under test. A support includes a plurality of supporting surfaces that are respectively positioned at different depths. A positioning mechanism positions the support behind a receptacle block.

Abstract: A device for holding one or more connectors and inserting the connectors into one or more receptacles of a unit for testing. The device comprises a base movable toward the receptacles, a connector holder holding the connectors that is movable with the base and movable relative to the base, and a biasing mechanism disposed relative to the connector holder to bias the connector holder toward the receptacles.

Abstract: A device for assisting in the release of a tandem wheel locking pin from a locking rail of a semi-trailer is disclosed. In a basic embodiment, the device consists of a gripping plate which engages the locking pin release rod of the tandem unit, a helical spring, and a hook plate which engages a frame member of the tandem unit such that tension is maintained on the spring. By locking the brakes of the tandem unit and rocking the trailer, friction between the locking rail and the locking pin is released, and the tension of the spring can pull the pin, at least partially, from the locking rail. An alternate embodiment of the device includes a positioning assist pin which may be placed into the locking rail at the point at which the tandem unit is to be moved to aid in aligning the locking pins at a new location.
