Such profiles make the flow velocity through the runners two times faster than that of the traditional fixed/caisson type OWC （oscillating water column）, that is, the runners may be able to get the dynamical energy eight times on the ideal. Besides, the runners counter-drive the inner and the outer armatures of the peculiar generator, respectively, and then the relative rotational speed is two times as fast as the speed of the single runner/armature. Such characteristics make the runner diameter large, namely the output higher, as you request, because the rotational moment of the power unit hardly act on the floating type platform. This paper, as the first step, discusses the platform behaviors at the normally oscillating wave. The platform behavior is affected by not only the length and the amplitude of the wave but also the relation between the weight of the platform and the buoyancy force of the floats.展开更多

This method can make the production fast and effective at small series or frequent manufacturing changes. The shop-floor control method, presented in this paper, offers a solution for the facing problem of fast and easy reconfiguration. The hardware of the controller designed modular with software components for online configuration. This solution allows sensor integration on different levels for every part of the manufacturing cell. With unified programming language and the machine specific controllers （post-processing） the cells can be defined easily by different types of human-machine interaction. The shop-floor control architecture is implemented and validated on an Adept SCARA （selective compliance assembly robot arm） robot. The robot is driven by standalone, low-level, interchangeable, software and hardware components.展开更多
