Patent number: 10852157Abstract: A method and apparatus of controlling movement of an aircraft. A turn path off of a planned route for an aircraft comprising a turn to direct the aircraft to an intercept point on the planned route is determined. A planned route indicator depicting the planned route, a turn path indicator depicting the turn path, and an aircraft position indicator indicating a position of the aircraft are displayed to an operator of the aircraft at the same time on a turn guidance display. Deviation limit indicators for the planned route, the turn path, or both, may be displayed on the turn guidance display. Indicator characteristics of the deviation limit indicators may be changed in response to aircraft deviations from the planned route or the turn path by more than the deviation limits. The turn guidance display is used to control the movement of the aircraft to follow the turn path.Type: GrantFiled: July 30, 2015Date of Patent: December 1, 2020Assignee: The Boeing CompanyInventors: Syed Tahir Shafaat, John Allin Brown, Minh-Tri Le

Patent number: 10688273Abstract: A dual pressure respiratory assistance device including a gas source which supplies a flow of gas into an air tube having a bubbler branch and a patient branch. A first tube that is connected to the bubbler branch is at least partially submerged in a fluid. An oscillatory relief valve cycles between first and second configurations. The relief valve includes an oscillating member which captures gas released through at least one hole in the first tube when the oscillating member is in a first position. The gas in the oscillating member causes the oscillating member to rise to a second position, wherein gas is released from the oscillating member and the at least one hole is blocked when the oscillating member reaches the second position.Type: GrantFiled: July 14, 2017Date of Patent: June 23, 2020Assignee: The Board of Trustees of Western Michigan UniversityInventors: Peter Allen Gustafson, Joseph David Hudson Taylor Barnett, Stephen Chiramukathu John, Hoa Tri Le

Patent number: 6930048Abstract: The invention is a method of etching an integrated circuit (IC) structure that includes a metal hard mask layer. The etching of the metal hard mask layer is performed by first feeding a gas mixture comprising a fluorine containing gas and oxygen (O2) gas to a reactor. The method then proceeds to generate a plasma that etches the metal hard mask layer. The method can be applied to either performing a via etch or a trench etch. Additionally, the invention teaches the removal of a photoresist layer without affecting the metal hard mask layer.Type: GrantFiled: September 18, 2002Date of Patent: August 16, 2005Assignee: Lam Research CorporationInventors: SiYi Li, S.M.

Patent number: 6630407Abstract: A semiconductor manufacturing process wherein an organic anti-reflective coating (ARC) is plasma etched with selectivity to an underlying dielectric layer and/or overlying photoresist. The etchant gas is fluorine-free and includes a carbon-containing gas such as CO gas, a nitrogen-containing gas such as N2, an optional oxygen-containing gas such as O2, and an optional inert carrier gas such as Ar. The etch rate of the ARC can be at least 10 times higher than that of the underlying layer. Using a combination of CO and O2 with N2 and a carrier gas such as Ar, it is possible to obtain dielectric:ARC selectivity of at least 10. The process is useful for etching contact or via openings in damascene and self-aligned contact or trench structures.Type: GrantFiled: March 30, 2001Date of Patent: October 7, 2003Assignee: Lam Research CorporationInventors: Douglas Keil, Jim Bowers, Eric Wagganer, Rao Annapragada, Tri Le
