Abstract: The system for which this patent applies regards the application of an emergency evacuation warning and information system for a generalized computer local area network. Utilizing the existing network for information transfer and the integrated hardware of each computer workstation, namely the input devices as warning trigger methods and visual display unit to provide a personalized individual evacuation plan pertaining to the location of each computer workstation.

Abstract: A shaped hull with a fixed angle keel with respect to the hull that when heeled, orients the keel to an angle of attack substantially related to the heel angle. The angle of attack being sufficient to create on the keel a lateral force substantially equal and opposite to the lateral force derived from the wind. The submerged portion of the hull, however, remains symmetrical and oriented parallel to the course sail as is its associated drag contribution vector. Thereby reducing or substantially eliminating the lateral force generated by the hull and the associated drag contribution. The movement of the shaped hull induces a lateral force on the keel without generating a lateral force and its associated drag on the hull, thus providing a sailboat with reduced drag without resorting to the prior art methods and their associated disadvantages.

Abstract: A tilt-rotor aircraft capable of vertical/short take-off and landing. The aircraft utilizes a co-axial counter rotating rotor system to provide vertical and horizontal thrust. The fuselage is positioned over the forward half of the rotor in the vertical take-off configuration and the rotors rotate ninety degrees to provide horizontal thrust in the forward flight mode. The aircraft uses conventional flight control surfaces during forward flight and uses cyclic rotor pitch control or a series of control surfaces located in the rotor wash to control the aircraft during vertical flight. One or more engines powering the rotor system provide thrust for the aircraft. The engine(s) can be located in the fuselage or in the wings. The aircraft uses lifting airfoils during forward flight which can include a wing/tail or a canard/wing configuration and uses a conventional tail for directional stability and control.
