An autonomous aerial vehicle for ventilating persons. The ventilation becomes necessary as a result of fires, accidents, or medical emergencies. In these and comparable cases, the aerial vehicle aids for ventilating a person quickly and independently of the transport links of a location or the traffic situation at the time so the state of the person is stabilized until the arrival of an emergency doctor or other rescue workers and the chances of survival improves. The aerial vehicle provides positional determination inside and/or outside buildings, recording of the surrounding area, ventilation of at least one person, and a communication method or mechanism.

A system and method for tracking performance of a physical activity of a user on a field are provided. The system comprises a visual aid unit and a controller. The controller is configured to receive sensor data indicative of at least one of position and direction of movement of the user on the field. The sensor data is generated in relation to a first performance of the physical activity by the user. The controller analyzes the sensor data to generate visual indicators for the user. The controller controls the visual aid unit to project the generated visual indicators during a second performance of the physical activity by the user for reference of the user. The visual indicators are configured to aid in improving the performance of the user in relation to the physical activity.

Methods and apparatus to create drone displays are disclosed. An example drone display design system includes an audience configuration definer to receive an input representing a configuration of an audience from a user, and a drone display designer to, by executing an instruction with a processor, design a drone display to present content to the audience based on the input.

An unmanned aerial system (UAS) that displays an image, video or other effect is described. The UAS may include a camera that captures the image for display. The UAS may be used in connection with a water display, and multiple UASs may operate together.

An example unmanned aerial vehicle traffic signal and related methods are disclosed. The example unmanned aerial vehicle includes a housing, a rotor, a motor, a sensor, a traffic signal, and a processor. The rotor is to lift the housing off ground. The motor is to drive the rotor. The sensor is to monitor traffic. The traffic signal is carried by the housing. The processor is to control the traffic signal based on the traffic monitored by the sensor.

Herein is disclosed a bounding-volume based unmanned aerial vehicle illumination management system comprising one or more processors, configured to define a plurality of bounding volumes within a region of unmanned aerial vehicle flight; determine a subset of unmanned aerial vehicles within a bounding volume according to an unmanned aerial vehicle flight plan; determine a combined lighting value of the subset of unmanned aerial vehicles according to an unmanned aerial vehicle illumination plan; and determine a surface illumination corresponding to the combined lighting value of one or more bounding volumes.

A vehicular alert system includes an autonomous aerial vehicle and a central computer. The autonomous aerial vehicle includes a processor, a display, and a detector. The processor controls a data transceiver. The detector detects one or more vehicular condition. The central computer communicates with the autonomous aerial vehicle via the data transceiver. The central computer includes a memory device. The memory device stores vehicular condition data and road condition data. The central computer communicates one of a vehicular condition or a road condition to the autonomous aerial vehicle. The processor of the autonomous aerial vehicle displays the received condition on the display.
