Patent number: 8740142Abstract: Various embodiments of the present disclosure provide an apparatus configured to automatically retrieve, service, and launch an aircraft. For retrieval, the aircraft drops a weighted cable, and pulls it at low relative speed into a broad aperture of the apparatus. In certain instances, the cable is dragged along guiding surfaces of the apparatus into and through a slot until its free end is captured. The aircraft becomes anchored to the apparatus, and is pulled downward by the cable into a receptacle. Guiding surfaces of the receptacle adjust the position and orientation of a probe on the aircraft, directing the probe to mate with a docking fixture of the apparatus. Once mated, the aircraft is automatically shut down and serviced. When desired, the aircraft is automatically started and tested in preparation for launch, and then released into free flight. A full ground-handling cycle is thus accomplished with a simple, economical apparatus.Type: GrantFiled: May 23, 2013Date of Patent: June 3, 2014Assignee: Aerovel CorporationInventors: Brian T. McGeer, Andreas H. von Flotow

Patent number: 8708278Abstract: For retrieval of a hovering aircraft, a cable, bar, or similar fixture is suspended in an approximately horizontal orientation across the retrieval area between two well-separated supports. The aircraft slowly flies into this fixture, which then slides along the aircraft in a direction approximately parallel with the aircraft's thrust line. This leads to the aircraft becoming fastened to the fixture by an interceptor or aircraft capturer, which in alternative embodiments are respectively on the aircraft or the fixture or both. Thrust is then reduced, and the aircraft comes to rest hanging from the fixture for subsequent removal. Retrieval is thus accomplished with simple and economical apparatus, light and unobtrusive elements on the aircraft, low risk of damage, and only moderate piloting accuracy.Type: GrantFiled: May 22, 2013Date of Patent: April 29, 2014Assignee: Aerovel CorporationInventors: Brian T.

Patent number: 8453966Abstract: An aircraft capable of thrust-borne flight can be automatically retrieved, serviced, and launched using equipment suitable for use on a small vessel, or a base with similarly limited space or irregular motion. For retrieval, the aircraft drops a weighted cable, and pulls it at low relative speed into a broad aperture of a base apparatus. Continued translation of the aircraft may pull the cable clear of the apparatus, in which case it can continue in free flight and return for another retrieval attempt. Alternatively, the cable will be dragged along guiding surfaces of the apparatus into and through a slot or similar channel, until its free end is captured. The aircraft, having thus become anchored to the base station, is then pulled down by the cable into a receptacle. Guiding surfaces of the receptacle adjust the position and orientation of a probe on the aircraft, while directing the probe to mate with a docking fixture.Type: GrantFiled: February 9, 2010Date of Patent: June 4, 2013Assignee: Aerovel CorporationInventors: Brian T.

Patent number: 8405723Abstract: A method and system for maintaining the line of sight of an airborne camera fixed on a target by compensating for overflight velocity of the aircraft. The compensation system automatically commands an angular velocity of the line of sight to maintain the camera pointing at the target being overflown. This angular velocity of the line of sight is computed based upon the aircraft overflight velocity and upon a vector from the aircraft to the target. This automatic compensation for aircraft overflight velocity causes the line of sight to remain fixed upon the target. The compensation system drives a gimbal system upon which the camera is mounted to perform this compensation automatically.Type: GrantFiled: October 6, 2009Date of Patent: March 26, 2013Assignee: Insitu, Inc.Inventors: Andreas H. von Flotow, Mathieu Mercadal

Patent number: 8226039Abstract: Vibration isolation devices and associated systems and methods are disclosed herein. In one embodiment, for example, an unmanned aircraft can include a fuselage having a first fuselage section and a second fuselage section adjacent to and at least approximately longitudinally aligned with the first fuselage section. The aircraft can also include at least one vibration isolation device coupling the first fuselage section to the second fuselage section. The vibration isolation device is translationally stiffer along a longitudinal axis than it is along a lateral and a vertical axis, and rotationally stiffer about a pitch and a yaw axis than it is about a roll axis.Type: GrantFiled: January 10, 2012Date of Patent: July 24, 2012Assignee: Insitu, Inc.Inventors: Andreas H. von Flotow, Tyler Patrick Horton

Patent number: 8140200Abstract: Turret assemblies for small aerial platforms, including unmanned aircraft, and associated methods. In one embodiment, an aircraft system can include a turret assembly having a payload with a line of sight to a target and a gimbal system carrying the payload. The gimbal system can include (a) a first support coupled to a first actuator to rotate about a first axis, and (b) a second support carried by the first support and coupled to a second actuator to rotate about a second axis generally transverse to the first axis. The turret assembly can also include a controller configured to direct movement of at least one of the first actuator and the second actuator such that the line of sight is pointed away from a point of impact before the turret assembly contacts the ground or another external structure during landing or capture operations.Type: GrantFiled: October 31, 2007Date of Patent: March 20, 2012Assignee: Insitu, Inc.Inventors: Stephen B.

Patent number: 7876359Abstract: A method and system for stabilizing images being taken by a video camera using electromechanical stabilization. The stabilization system performs inter-frame stabilization based on the velocity of a vehicle on which the video camera is mounted and the pan rate of a line-of-sight controller of the video camera. The inter-frame stabilization is performed by a software component by moving a display area (or viewport) within a larger image area. The stabilization system converts an inter-frame stabilization adjustment into a pan rate adjustment so that the line-of-sight controller will keep the desired object within the image area of the camera.Type: GrantFiled: December 1, 2003Date of Patent: January 25, 2011Assignee: Insitu, Inc.Inventors: Andreas H. von Flotow, Mathieu Mercadal, Brian T.
