Patent number: 11952101Abstract: An assembly integrates an aft wing spar root fitting to an aircraft fuselage when joining the aircraft wing to the aircraft body. The assembly provides structural strength to the connection between the aircraft wing and the aircraft body, provides corrosion prevention and provides improved inspection capabilities and repair capabilities to the aircraft wing and aircraft body connection.Type: GrantFiled: March 3, 2022Date of Patent: April 9, 2024Assignee: The Boeing CompanyInventors: Michael R. Rush, Orion P. Watson, Daniel H. Fletcher, Ryan A. Fear, Brent E. Beneke, David H. Leibov, Patricia W. Estell, Norma L Alvarez-Quinones, Soo H. Teoh, Jesse R. Wiseman, Mark E. Shadell, Mark R.

Patent number: 11830407Abstract: A fault-tolerant display system includes a dual thin film transistor (TFT) panel with pixel cells having two independently-controlled switching transistors; as such, primary source and gate drivers are operative to drive the display with first TFT transistors, while secondary source and gate drivers are operative to drive the display with second TFT transistors. As the display incorporates an additional TFT within the pixel cell which is driven independently, reliability is increased even at the pixel level. In this way, individual pixels of the LCD panel are driven simultaneously and independently by two pairs of source drivers and gate drivers, such that if one of the driver pairs fails due to some fault, the other driver pair can continue to drive the LCD panel without loss of information despite the failure of the first driver pair.Type: GrantFiled: February 12, 2018Date of Patent: November 28, 2023Assignee: L3 Technologies, Inc.Inventors: Mark W.

Patent number: 10847106Abstract: Fault-tolerant liquid crystal displays are delineated for avionics systems. At least some example embodiments are methods including providing an avionics display full screen on the LCD, the providing being implemented by driving source signal lines of the LCD by way of a first source driver circuit through a first set of FETs; driving gate signal lines of the LCD by way of a first gate driver circuit through a second set of FETs; preventing back biasing of a second source driver circuit by electrically isolating the source signal lines from the second source driver circuit; and preventing back biasing of a second gate driver circuit by electrically isolating the gate signal lines from the second gate driver circuit.Type: GrantFiled: February 9, 2018Date of Patent: November 24, 2020Assignee: L3 TECHNOLOGIES, INC.Inventor: Mark W.

Patent number: 10527896Abstract: Various circuits may benefit from suitable protection. For example, certain displays, such as active matrix liquid crystal displays, may benefit from enclosures configured to protect driver circuits from high intensity radiated fields. A system can include a first protective conductive coating layer. The system can also include a first insulating layer on the first protective conductive layer. The system can further include a signal conductive layer on the insulating layer. The system can additionally include a driver layer mounted to the signal conductive layer. The system can also include a second insulating layer above the driver layer. The system can further include a second protective conductive coating layer on the second insulating layer. The system can additionally include one or a plurality of conductive elements disposed between the first protective conductive coating layer and the second protective conductive coating layer to form an enclosure around the driver layer.Type: GrantFiled: December 8, 2017Date of Patent: January 7, 2020Assignee: L3 TECHNOLOGIES, INC.Inventors: Michael G. Abernathy, Mark W. Fletcher, Sanjay Tripathi

Publication number: 20130278556Abstract: A display system includes a backing, a touch-screen, and a front-mounted flexible display. The backing provides a rigid substrate or base upon which the other components are mounted. The touch-screen includes a conductive rear panel and a conductive front panel separated from the rear panel by an insulating air gap. The front conductive panel is flexible enough and positioned close enough to the rear panel that touching the front panel causes enough deflection of the front panel to cause it to bridge the air gap locally and to contact the rear panel. Thus, in this way the electrical path (and therefore the resistance of the circuit) can be mapped to the particular location on the touch-screen touched by the user.Type: ApplicationFiled: April 22, 2013Publication date: October 24, 2013Inventors: Jerome S. CONWAY, Mark W. FLETCHER
