Abstract: Unmanned aerial vehicles and methods for unmanned aerial vehicles are described in various aspects herein. In at least one aspect, an unmanned aerial vehicle (UAV) includes a cooling structure configured to dissipate heat, and an air channel configured to dissipate heat from the cooling structure via an airflow. The UAV also includes at least one fan configured to provide the airflow through the air channel, and one or more sensors configured to receive ambient condition information associated with an ambient condition in a vicinity of the UAV. The UAV further includes one or more processors configured to trigger a reduction of the airflow through the air channel based on the ambient condition information. The ambient condition information may include dust information indicating a dust pollution in the vicinity of the UAV. Additionally or alternatively, the ambient condition information may include weather information indicating rain in the vicinity of the UAV.

Abstract: Various embodiments are generally directed to techniques for wire-free charging. Some embodiments are particularly directed to a wire-free charging system that is able to limit or prevent a radio frequency (RF) signal source from interfering with operation of the wire-free charging system, such as, for instance, a transmitter (TX) signal of a cellular device being charged by the wire-free charging system. In some embodiments, a wire-free power source may be able to detect an RF signal source and alter one or more operational parameters of the wire-free charging system to prevent the RF signal source from interfering with operation of the wire-free charging system.

Abstract: A heat pipe is provided that is adapted for use as part of an antenna. The heat pipe includes a first conductive shell portion; a second conductive shell portion; and an insulating shell portion disposed between and connected to the first conductive shell portion and the second conductive shell portion. A wick structure is disposed within the sealed chamber.

Abstract: An example system for projector image alignment. The system for projector image alignment can include a processor to compare a first calibration-pattern image projected by a first projector and at least a portion of a second calibration-pattern image projected by a second projector and generate a geometric model of an aligned image for display by both the first projector and the second projector. The processor can also send a first projector portion of the aligned image to the first projector based on the geometric model of the aligned image.

Abstract: Disclosed herein are systems and techniques to adapt an image to a gaze vector of a user or project content based on a distance between an appendage of a user and a at least a portion of a projected image. The system can include a projector to project an image and a camera to capture an image. The system can determine a gaze vector of a user and adapt the projected image based on the gaze vector. Additionally, the system can determine a distance between an appendage of the user and the projected image and project content based on the distance.

Abstract: Techniques related to improved front facing camera performance using display light during exposure of a scene are discussed. Such techniques may include providing, via a display device, exposure light during exposure of the scene such that providing the exposure light includes setting regions of the display device to different colors during exposure.
