Abstract: A content visualization system generates visual content for a visualization device based on visual content of an event. The content visualization system collects visual content and source perspective data from visual content sources. The visualization device requests visual content from the content visualization system by providing device perspective data to the content visualization system. The content visualization system generates visual content for the visualization device based on the visual content from the visual content sources, the source perspective data, and the device perspective data. The content visualization system can determine visual content that is relevant to the device perspective by identifying source perspectives that overlap with the device perspective. The content visualization system generates visual content for the visualization device based on the identified visual content.

Abstract: A variable pitch propeller is designed to adjust the pitch of the propeller blade during flight to maximize the propeller efficiency. The propeller blade may comprise airfoil cross-sections. Each cross-section may be composed of different materials at the leading edge and trailing edge. In various embodiments, these materials are selected and oriented to achieve the necessary elastic moduli of the leading and trailing edge for the airfoil cross-section. During liftoff, the airfoil at the blade tip possesses a high blade pitch (e.g. 20 degrees), thereby increasing the generated lift on the propeller blades. During flight or hover conditions when maximal lift is no longer required, the trailing edge of the airfoil displaces upward and reduces the blade pitch to minimize the drag forces on the blade tip.

Abstract: An unmanned aerial vehicle manages storage of data and transfer between other connected devices.

The stored sensor data is transferred from the buffer to a non-volatile storage responsive to the battery level dropping below a predefined threshold or detecting that the unmanned aerial vehicle is stationary and a shutdown may be imminent.
