Abstract: Systems and methods to detect objects and associated properties may be performed by an aerial vehicle having one or more propellers and one or more microphones. The aerial vehicle may emit propeller noise patterns via the propellers during operation, and the aerial vehicle may receive echoes of the propeller noise patterns via the microphones. Based on the emitted noise patterns and received echoes, the aerial vehicle may detect objects and associated properties within an environment of the aerial vehicle. In addition, the aerial vehicle may emit encoded propeller noise patterns via the propellers during operation to communicate with other aerial vehicles, and other aerial vehicles may receive the encoded propeller noise patterns via microphones. Using such encoded propeller noise patterns, a plurality of aerial vehicles may communicate and/or coordinate operations with each other.

Abstract: Systems and methods to measure states of charge of a battery may include an ultrasonic sensor and a control system. For example, the control system may instruct the ultrasonic sensor to emit ultrasonic waves toward a battery, and may instruct the ultrasonic sensor to receive echoes of the emitted ultrasonic waves reflected back from the battery. In addition, the control system may process data associated with the emitted waves and received echoes, including properties associated with the waves and echoes, such as a time of flight, frequency, amplitude, wavelength, phase, duration, or others. Based on the properties of the received echoes, and by comparison with expected properties, various physical, mechanical, chemical, and/or material characteristics of the battery may be determined, based on which a state of charge and/or a state of health of the battery may further be determined.

Abstract: Systems and methods to maintain a fleet of batteries may include a plurality of electrically connected batteries and a control system. For example, the connected batteries may be stored and connected via a cabinet or rack. The control system may determine desired states of charge and/or desired storage temperatures for the connected batteries, in order to maintain at least one battery available to meet demand while also minimizing an aging rate of the fleet of batteries. Accordingly, the control system may adjust states of charge associated with the fleet of batteries to the desired states of charge, which may include various distributions of states of charge, and the control system may also adjust storage temperatures associated with the fleet of batteries.

Abstract: A system may include a receiver configured to receive sensor data from one or more aerial vehicles, the sensor data including map data including sensed data related to an aerial view from one or more aerial vehicles of terrain and objects on the terrain. The system may also include a map updating processor in communication with the receiver. The map updating processor may receive the map data and identify a geographic location and/or an orientation associated with the map data. The map updating processor may also align, based at least in part on the geographic location and/or the orientation, the map data with a virtual aerial map providing an aerial view of terrain and objects on the terrain. The map updating processor may also incorporate at least a portion of the map data into the virtual aerial map and generate an updated virtual aerial map.
