    Abstract: Systems, computer readable medium and methods for navigation correction for excessive wind in an autonomous drone are disclosed. Excessive winds can be a particular problem for small autonomous drones as safety and retrieval of the autonomous drones is important and the autonomous drones often have limited thrust and batteries. Autonomous drones are disclosed that detect and correct flight plans when excessive winds are detected. The autonomous drone determines based on the severity of the excessive winds whether to return to a home position which is typically a position of a user of the autonomous drone or to land in place. If the excessive winds subside, then the autonomous drone returns to its original flight plan at the point where the autonomous drone was blown off course by the excessive winds. The autonomous drone detects excessive winds either directly by sensor data or inferentially by unanticipated movement of the autonomous drone.

    Abstract: System, methods, devices, and instructions are described for fast boot of a processor as part of camera operation. In some embodiments, in response to a camera input, a digital signal processor (DSP) of a device is booted using a first set of instructions. Capture of image sensor data is initiated using the first set of instructions at the DSP. The DSP then receives a second set of instructions and the DSP is programmed using the second set of instructions after at least a first frame of the image sensor data is stored in a memory of the device. The first frame of the image sensor data is processed using the DSP as programmed by the second set of instructions. In some embodiments, the first set of instructions includes only instructions for setting camera sensor values, and the second set of instructions includes instructions for processing raw sensor data into formatted image files.
