Abstract: The present invention includes a power cable tension control device having at one end an adapter capable of insertion into a computer port and at the opposing end a cable retaining structure for retaining a power cable, such as an AC power cable. The adapter does not electrically communicate with the retained power cable and therefore does not act as a conduit through which the power cable electrically communicates with the computer. The computer cable communicates with the computer using a port away from the adapter. Thus, the present invention provides a device that further anchors the power cable to the computer thereby reducing strain on the plug region of the power cable or the computer port, which prolongs the life of the power cable or computer port.

Abstract: A roadable aircraft capable of flying as well as road travel. The wings of the roadable aircraft are defined by inner and outer wing panels. The outer wing panels are folded with a fold mechanism that rotates each of the outer wing panels from a substantially horizontal extended flying position to a substantially vertical extended position and then folds each of the outer panels into a direction parallel to the travel direction defined by the fuselage. An operator controlled selectable drive mechanism allows the operator to select either the propeller or drive wheel to receive power from the engine shaft.
