Abstract: A novel zip-line construction capable of three-dimensional movement is disclosed. The zip-line construction generally comprises a single or dual cable member having two ends, a trolley assembly having the ability to traverse a desired distance along the cable member and at least one device capable of attaching the cable member to a separate fixed body. The zip-line of the invention expands movement of the traditional zip-line from two-dimensional movement to three-dimensional movement, thereby advantageously providing a longer and more thrilling ride experience.

Abstract: An optical module inspection circuit on an optical platform includes an optical module carrier for precisely aligning optical devices with optical interfaces of inspection equipment located at fixed positions in the optical module inspection circuit. The module-includes an apparatus for conveyance along a top surface of the optical platform. The module may be conveyed automatically to predetermined positions on the optical platform to automate alignment and positioning of optical devices with respect to optical inspection stations in the optical test circuit.
