摘要： Techniques and examples pertaining to single channel line-of-sight (LOS) communication are described. The transmitting end of the LOS communication involves direct modulation of a light emitted from a light emitter. The receiving end of the LOS communication involves receiving a video stream of the light emitter emitting the light, wherein the video stream comprises a plurality of video frames that are continuous in time. The receiving end of the LOS communication also involves converting the video stream to a binary string comprising a plurality of binary bits. Each of the binary bits corresponds to a respective one of the plurality of video frames, and the binary string contains a repeated binary pattern representing a message being conveyed. The receiving end of the LOS communication also involves extracting the binary pattern from the binary string and then decoding the binary pattern to obtain the message.

摘要： Example positioning systems and methods are described. In one implementation, a landing platform includes a base having an aperture and multiple positioning arms attached to the base. Each of the multiple positioning arms can rotate between an unlocked position and a locked position. Additionally, each of the multiple positioning arms are configured to engage a positioning ring on an unmanned aerial vehicle (UAV) and further configured to reposition the UAV on the base.

摘要： Example landing platform systems and methods are described. In one implementation, a landing platform includes a top plate configured to support an unmanned aerial vehicle (UAV), where the top plate has a plurality of slots therethrough. A rotating plate is located adjacent the top plate and includes multiple centering pins extending therefrom and extending through the plurality of slots in the top plate. A motor is capable of rotating the rotating plate, which causes the multiple centering pins to center the UAV on the top plate.

摘要： Described herein are systems, methods, and devices for recovering unmanned aerial vehicles (UAVs), such as UAVs that are trapped in an obstacle such as a tree. In particular, a method is described, the method including determining location parameters associated with a trapped UAV; navigating to the proximity of the UAV; determining launching parameters and a target associated with the launch of a launching device; and causing the launch of a launching device towards the target. The launching device may include a tether, such that a user may pull on the tether to dislodge the trapped UAV from the tree.
