Patent number: 10626824Abstract: A thrust reverser includes: a thrust-reversing element movable between a stowed position and a deployed position; at least one hydraulic actuator operably coupled to move the thrust-reversing element between the stowed and deployed positions; at least one hydraulic primary lock configured to transition, in response to a first activation pressure, between an engaged state, where movement of the thrust-reversing element is inhibited, and a released state, where movement of the thrust-reversing element is uninhibited; and a directional control unit fluidly coupled to the hydraulic actuator and the hydraulic primary lock, the directional control unit configured to transition from a first stage to a second stage in response to a second activation pressure that is greater than the first activation pressure, and where a transition from the first stage to the second stage by the directional control unit causes the hydraulic actuator to move the thrust-reversing element to the deployed position.Type: GrantFiled: March 19, 2018Date of Patent: April 21, 2020Assignee: Woodward, Inc.Inventors: Joseph Thomas Kopecek, Julian Sweet

Publication number: 20120031470Abstract: The invention provides solar panel systems, which may be applied to surfaces such as residential rooftops. The invention also provides methods of installing solar panel systems. A solar panel system may comprise one or more module, which may comprise one or more solar panels and a rack. A solar panel may comprise a polymer, and may not comprise glass or a metal frame. The rack may include three footings and a plurality of adjustable fasteners that may enable the module to reside on an uneven surface. The rack may also include integrated electronic components and a microinverter. A module may yield a desired power output, and may generate performance monitoring data.Type: ApplicationFiled: June 17, 2010Publication date: February 9, 2012Inventors: Dmitry Dimov, Julian Sweet, Mark Goldman, Theo Mann, Christine M.
