A kind of intestine endoscopic robot of resonant ciliary structure is proposed in the paper. The robot is simple-structured, driven by piezoelectric bimorph, a structure of unilateral burr surface array is designed, resonant and the non symmetry friction between flexible leg and the contact surface is used to drive the structure move ahead. The motion principles of robot have been given theoretical...
Truncated Airy pulses [1-3] were launched in an optical fiber close to its zero dispersion point allowing the effect of third order dispersion (TOD) to play a dominant role in the dynamics of pulses. When the truncated Airy pulse propagates in the presence of pure quadratic dispersion it lives for a finite distance until it reaches its divergence area (Fig.1(a)). However when the pulse dynamics is...
We present modulators developed in the projects “HELIOS”, and “UK Silicon Photonics”, integration with modulator driver to produce the first silicon modulator fully integrated with BiCMOS, and multiplexed photonic crystal modulators for ultra-low power operation.
A new fault location algorithm for EHVAC mixed cable-overhead line based on fault zone identification is proposed. When the failure happened, first, according to the uniform transmission line equations, taking cable-overhead line connection point as reference, this article puts forward the fault zone identification method; then, deducts fault point positioning functions in different sections and gets...
