System design and development are fundamental capabilities for an engineer. The Department of Control Engineering at the National Institute of Technology, Nara College, has been offering a course called “Practical System Design,” a unique opportunity for students to experience the entire process of developing an autonomous mobile robot, to fourth-year students for about 20 years. However, in recent...
Handwritten characters involve much variant appearance by each individual. Especially, brush-writing, such in Japanese or Chinese calligraphy, is very skillful action, since the writer is required to activate the calligraphic technique, such as the pullout, the stop, and flick, with softness of the brush. In this article, we implemented a virtual brush-writing system with the pen-style haptic device...
The performance of an externally-pumped photorefractive phase conjugator is greatly improved, especially in stability and response to signal change, by the phase control of incident beams. Using piezoelectrically-driven mirrors in all incident optical paths, the backward pump is made incoherent with the other input beams and the fluctuation of mutual mean phases between forward pump and signal beams...
