  • Patent number: 8371520
    Abstract: A hybrid fixed wing aircraft converts into a roadworthy vehicle in a matter of seconds therefore operating efficiently in both air and ground transportation systems. The single piece wing is mounted on a skewed pivot that is on the lower portion of the fuselage and is operated by a pushbutton operating system. The aircraft includes telescopic twin boom tail design that when extended allows good pitch stability and damping. The aircraft's wing area may be increased with additional telescopic wing tip segments. This allows an increase in aspect ratio, hence improving efficiency at high loads. This feature also creates a reduction in induced drag at cruise speed by simply retracting the tips in flight. The vehicle has a unique synchronized control system that switches from flight to ground mode without input from the operator, thereby providing a natural interface for the operator.

  • Patent number: 7018366
    Abstract: VARS (Vacuum Assisted Relief System) is a aircrew bladder relief system that allows the pilot, whether male or female, to urinate in flight with comfort and convenience. There are three principle parts to the system, The pump, the garment, and the receiver. A pump and battery pack may be mounted in a breast pocket or attached to a torso harness at breast level. Locating the pump at a level higher than the garment insures little or no “leak back” to the garment. A garment worn like a diaper or underwear, includes an intake manifold comprised of a number of perforated tubes sandwiched between layers of material. Urine from a user is collected in the garment, drawn into the manifold tubes through these holes, by means of vacuum from the pump. Collected urine then passes through a hose into containment bag or receiver.
