Autonomous UAV Battery Swapping

One of the main hindrances of unmanned aerial vehicle (UAV) technology are power constraints. One way to alleviate some power constraints would be for two UAVs to exchange batteries while both are in flight. Autonomous mid-air battery swapping will expand the scope of UAV technology by allowing for indefinite flight times and longer missions. A single board computer will control each UAV’s flight software to respond to inputs to align with each other mid-flight. When the two UAVs have joined, mechanical components will exchange a depleted battery on the worker UAV for a freshly charged battery that belongs to the battery supply UAV. After the exchange, the drones will then detach themselves from each other, and the worker UAV will resume its mission while the battery supply UAV returns back to the ground control station

Recent advances in multidimensional systems and signal processing: an overview

In this paper, we present an overview of recent advances in multidimensional (MD) systems and signal processing. We focus on topics closely related to the four papers selected into the special session of 'recent advances in multidimensional systems and signal processing' at ISCAS 2015. The paper starts with an overview of the theory of MD IIR digital filters and its applications ranging from image/videos of light-fields to microwave and mm-wave antenna array processing. State-space formulation for the realization of MD IIR notch filters is also discussed as applicable to image processing scenarios. Thereafter, new developments in visual tomography-based imaging systems that exploit MD signal processing towards safety and health applications are discussed. The paper also reviews new theoretical developments in modeling of physical systems. Recent advances in MD Kirchhoff circuit realizations for some physical systems including finite speed heat diffusion are reviewed
