Patent number: 8797512Abstract: A three dimensional imaging camera comprises a system controller, pulsed laser transmitter, receiving optics, an infrared focal plane array light detector, and an image processor. The described invention is capable of developing a complete 3-D scene from a single point of view. The 3-D imaging camera utilizes a pulsed laser transmitter capable of illuminating an entire scene with a single high power flash of light. The 3-D imaging camera employs a system controller to trigger a pulse of high intensity light from the pulsed laser transmitter, and counts the time from the start of the transmitter light pulse. The light reflected from the illuminated scene impinges on a receiving optics and is detected by a focal plane array optical detector. An image processor applies image enhancing algorithms to improve the image quality and develop object data for subjects in the field of view of the flash ladar imaging camera.Type: GrantFiled: September 14, 2012Date of Patent: August 5, 2014Assignee: Advanced Scientific Concepts, Inc.Inventors: Roger Stettner, Howard Bailey, Brad Short, Laurent Heughebaert, Patrick Gilliland

Publication number: 20110057075Abstract: Takeoff and landing modes are added to a flight control system of a Vertical Take-Off and Landing (VTOL) Unmanned Air Vehicle (UAV). The takeoff and landing modes use data available to the flight control system and the VTOL UAV's existing control surfaces and throttle control. As a result, the VTOL UAV can takeoff from and land on inclined surfaces without the use of landing gear mechanisms designed to level the UAV on the inclined surfaces.Type: ApplicationFiled: November 18, 2010Publication date: March 10, 2011Applicant: HONEYWELL INTERNATIONAL INC.Inventors: David C.

Patent number: 7896293Abstract: The process improves the maneuverability of an aircraft during the approach to landing and then flare-out phases, the aircraft being equipped with air brakes. According to the process, the air brakes are put in a first deployed position during the approach phase, and as a function of a representative parameter of a given altitude and in case of a steep angle approach, they are actuated to transition to a second more retracted position than the first position so as to achieve a flare-out allowing to essentially maintain the same angle of incidence, corresponding in case of a steep angle approach to achieve a flare-out with habitual exterior piloting references during the flare-out phase.Type: GrantFiled: June 11, 2008Date of Patent: March 1, 2011Assignee: AirbusInventors: Stéphane Boissenin, Jacques Rosay

Patent number: 7874521Abstract: A system operates to guide an aircraft to or along a route designed to maintain the aircraft within a safe glide distance of an acceptable emergency landing area. The system uses a database of emergency landing areas with glide characteristics of an aircraft to determine a route that minimizes travel time or other specified parameter, while keeping the aircraft within a safe glide distance of a landing area in the database meeting the landing requirements for the aircraft.Type: GrantFiled: October 17, 2006Date of Patent: January 25, 2011Assignee: Hoshiko LLCInventor: Gary Stephen Shuster

Publication number: 20110006164Abstract: A system for automatic or auto pilot controlled landing of air vehicle (2) with an undercarriage (10) with a substantially plane lower side, at a stationary or mobile landing place is described. The system is primarily characterized in that the landing plate is settable after two axes in roll and pitch, by a set mean controlled in relationship to the air vehicle and the horizontal plane. The air vehicle (2) and the landing plate (3) are provided with transmitter and receiver which define and communicate the mutual distance and the relative angles between the landing plate (3) and the undercarriage (10). Said set means is arranged to set said two axes such that the landing plate (3) will be substantially parallel to the lower side of the undercarriage (10).Type: ApplicationFiled: January 14, 2009Publication date: January 13, 2011Inventors: Johan Märtensson, Torbjörn Segerström, Magnus Magnus, Andreas Gising
