Abstract

A quadrotor is proposed than can both fly and roll. The proposed robot employs passively reconfigurable structures to enable the rolling, tightly coupling the attitude of the robot to the rolling cage. The benefits are precise rolling and turning control as well as improved rolling efficiency. The passively reconfigurable structures are enabled by pre-stretched elastic springs to generate a nonlinear restoring torque. The robot leveraged the superior maneuverability in the rolling mode to take photos of the surroundings at different tilting and panning angles to construct a panoramic image. Besides, the results of the power measurements show a significant reduction in the cost of transport brought by at low speed, equating to a 15-fold extension in the operational range.

Abstract

A Far-UVC excimer light source contains a first electrode adapted to be energized, a second electrode adapted to be energized, a body defining a cavity that is filled with an excited molecule complex between the first and second electrodes; and a Far-UVC optical dielectric coating filter which is a Far-UVC filter attached to the interior side of the first electrode and adapted to filter a Far-UVC light excited in the cavity of the body. The Far-UVC dielectric coating is located inside the light source, between the cavity with the excited molecules and the first electrode. The Far-UVC filter attached to the interior side of the first electrode is a transmissive Far-UVC optical filtering dielectric coating or coated glass which is integrated, placed on, or near the interior side of the first electrode inside the light source.

Abstract

The present invention provides a cable planning method based a fast marching method applied with simulated annealing (FMM/SA) algorithm. In the FMM/SA algorithm-based cable planning method, the FMM used to obtain the optimal submarine cable path with the lowest life-cycle cost, and the SA algorithm is used to continuously adjust the weight of each design consideration with the aim to achieve an optimal cable path that is as close as possible to a real-life cable path which has a history of cost-effectiveness and resilience. The set of weights contributed to the optimal cable path is then used as an optimal set of weights of design considerations for cable path planning. The FMM/SA algorithm-based cable planning method can provide a computationally effective approach which has lower computation costs and better performance in generating cable paths with optimal life-cycle cost and reliability.
