Abstract: Controlling an unmanned aerial vehicle to traverse a portion of an operational environment of the unmanned aerial vehicle may include obtaining an object detection type, obtaining object detection input data, obtaining relative object orientation data based on the object detection type and the object detection input data, and performing a collision avoidance operation based on the relative object orientation data. The object detection type may be monocular object detection, which may include obtaining the relative object orientation data by obtaining motion data indicating a change of spatial location for the unmanned aerial vehicle between obtaining the first image and obtaining the second image based on searching along epipolar lines to obtain optical flow data.

Abstract: An unmanned aerial vehicle (“UAV”) receives location information describing geographic boundaries of a polygonal no-fly zone (“NFZ”), the NFZ having a plurality of virtual walls each associated with a geographic line segment. The UAV identifies a closest and a second closest virtual wall of the plurality of virtual walls of the NFZ to a geographic location of the UAV. The UAV determines a first distance from the location of the UAV to a portion of the closest virtual wall nearest to the location of the UAV and a second distance from the location of the UAV to a portion of the second closest virtual wall nearest to the location of the UAV. In response to the first and/or second determined distances being less than a threshold distance, the UAV modifies a velocity and/or a trajectory of the UAV such that the UAV does not cross the virtual walls.

Abstract: A novel vestibular implant system is described. An implantable vestibular stimulator provides vestibular stimulation signals to stimulate target neural tissue for vestibular sensation by a patient. One or more motion sensors are controllably powered by the vestibular implant system and develop a motion signal reflecting head motion of an implant patient. The vestibular stimulator includes at least two different operating modes: i. a sensor controlled mode wherein the motion sensor is powered and the vestibular stimulation signal is developed as a dependent function of the motion signal, and ii. a sensor independent mode wherein the motion sensor is unpowered and the vestibular stimulation signals, if any, are developed independently of the motion signal.

The elastic plate has an annular rim that rests against an outer surface of the support plate. A fastening ring surrounds the support plate and is axially displaceable relative thereto. A radially inwardly directed projection of the fastening ring acts upon a rim of the elastic plate such that displacement of the fastening ring in a fastening direction results in an increase of the distance of the rim from the upper surface of the support plate.
