Abstract: A method is provided for horizon detection. The method includes acquiring an image that depicts a view of an environment, and defining a line pattern of lines that divide the image into respective pairs of image segments. The line pattern is formed of lines that are parallel, or intersecting at a common point of intersection. The method includes searching the lines of the line pattern to identify one of the lines as an estimated true horizon in the image that divides the image into a respective pair of image segments at a boundary of greatest difference in average brightness between the image segments from among the respective pairs of image segments. The method includes determining true horizon in the image from the estimated true horizon. The method may also include an evaluation of the estimated true horizon or the true horizon as to verify one or more expected characteristics.

Abstract: A surface mounting device is disclosed. The mounting device may be configured for coupling to a sensor package. The mounting device may include an active adherent and one or more passive adherents. The active adherent may include a suction cup with a powered pressurizer in fluid communication with a cavity of the suction cup. The passive adherent(s) may include one or more pads having an adhering coating. The mounting device may be positioned proximate a suitable mounting surface by a vehicle, such as an aerial vehicle. Once proximate a suitable surface, the mounting device may first attach itself to the surface using the active adherent. The mounting surface may attach itself to the surface using the passive adherent(s) if a more permanent attachment is desired, and/or if power is in short supply.

Abstract: A vehicle includes a fuselage having a longitudinal axis and a propulsion system that is coupled to the fuselage. The vehicle also includes a pair of articulated appendages that is coupled to the fuselage. Each one of the articulated appendages includes a plurality of airfoil segments and is moveable between a ground configuration, in which each one of the pair of articulated appendages supports the vehicle during takeoff or landing of the vehicle, and a flight configuration, in which each one of the pair of articulated appendages produces lift during flight of the vehicle.
