Patent number: 11267556Abstract: A method of using a split winglet includes providing an aircraft having a winglet attach fitting attaching a split winglet to a wing. The split winglet has an upper winglet and a lower winglet. The method additionally includes maintaining the winglet attach fitting and winglet at a first height relative to a fuselage when the aircraft is non-flying, and moving the winglet attach fitting and winglet to a second height relative to the fuselage when the aircraft is flying, the second height being higher than the first height.Type: GrantFiled: February 8, 2019Date of Patent: March 8, 2022Assignee: The Boeing CompanyInventors: Philipp Witte, Darrell D. Campbell, Jr., Billy P. Tung, Fedor Kleshchev

Patent number: 9845162Abstract: The present disclosure provides a system, method, and apparatus for a protective finish for an airfoil. In one or more embodiments, the disclosed method involves providing a sheath, and applying the sheath to the surface of the airfoil. In one or more embodiments, the sheath wraps around the surface of the airfoil from the leading edge of the airfoil towards the trailing edge of the airfoil. In at least one embodiment, the sheath covers approximately 50 percent to approximately 70 percent of the chord length of the airfoil. In some embodiments, the sheath is manufactured from at least one polymer, such as a polyurethane and/or a floropolymer. In one or more embodiments, the airfoil is a winglet, a raked wing tip, and/or a wing.Type: GrantFiled: May 3, 2013Date of Patent: December 19, 2017Assignee: THE BOEING COMPANYInventor: Darrell D. Campbell, Jr.

Patent number: 7624987Abstract: In the present invention, a method is provided for biasing or controlling the deal of cards, or other indicia, to players of a game. The cards are biased such that each player in the game will receive a hand that is close in ranking to all the other players of the game. Each player of the game is assigned a deviation multiplier selected from a list. Next an initial single hand rank is randomly selected and each player's deviation number is used to identify a range of hand rankings from which each player's hand is selected. If the initial hand ranking is 50 and the average deviation for a player is 2, the player's hand ranking will be in the range of 50±(10×deviation multiplier) or 50±(20) which is 30-70. (i.e. 50±20 or 50?20=30 and 50+20=70). Biasing the deal of the cards increases the excitement and competition of the game by allowing all players of the game to have relatively close hand rankings.Type: GrantFiled: February 6, 2006Date of Patent: December 1, 2009Assignee: Seven Generations, Inc.Inventors: Darrell D. Campbell, David Richards, Spencer Peterson
