Resonant Beam Charging (RBC) is a wireless charging technology which supports multi-watt power transfer over meter-level distance. The features of safety, mobility and simultaneous charging capability enable RBC to charge multiple mobile devices safely at the same time. To detect the devices that need to be charged, a Mask R-CNN based dection model is proposed in previous work. However, considering the constraints of the RBC system, it's not easy to apply Mask R-CNN in lightweight hardware-embed...

Resonant Beam Charging (RBC) is a promising multi-Watt and multi-meter wireless power transfer method with safety, mobility and simultaneously-charging capability. However, RBC system operation relies on information availability including power receiver location, class label and the receiver number. Since smartphone is the most widely-used mobile device, we propose a Mask R-CNN based smartphone detection model in the RBC system. Experiments illustrate that our model reduces the smartphone scanni...

Existing Unmanned Aerial Vehicles (UAVs) mainly rely on the direct ground-to-UAV communications over the unlicensed spectrum, which can only operate within the visual line of sight. Integrating UAVs into cellular networks is a promising solution to extend the range but poses new challenges to the transport protocols. To ensure the flight safety, the transmission of UAV commands and mission-related data is required to be reliable with low latency. In this paper, we propose a Low-latency Reliable ...
