Resonant coils and metamaterials are useful to increase the effective range of a wireless power transfer system. We experimentally compared the characteristics of a resonant coil and a metamaterial with similar sizes. The resonant coil had higher Q and higher coupling ability with a loop than did the metamaterial. The transmission coefficient with the resonant coil system averaged 3.6 times higher...
This paper presents a design method to generate a ladder diagram (LD) automatically with the control Petri Net (CPN) for control of discrete event system. This method describes the specification of a practical system with the CPN that associates operations with places and conditions with transitions. Based on the firing regulation of transition, the relationship of places, conditions, and events are...
