Title: Mobile station and method for controlling mobile station side communication, base station and method for controlling base station side communication, and communication system
Inventor: YAMAGISHI ATSUSHI
IPC: H04W4/90
Filed: 2004-06-01
Abstract: When an urgent communication or the like is caused, it is possible to handle the urgent communication or the like with a higher priority by a simple and effective method. There is provided a communication system in which at emergency, a base station (100) and a mobile station (200a) establish an urgent communication. The mobile station (200a) switches the output adjustment from the normal mode to the emergency mode and transmits an urgent communication with an output as large as possible. The base station (100) receives the strong radio wave from the mobile station (200a) which has transmitted the urgent communication. The base station (100) continues to output a suppression signal to make the other mobile stations suppress a signal strength. The other mobile stations are suppressed by the perspective effect and the base station (100) cannot receive communications other than the urgent communication. Only the mobile station (200a) which has transmitted the urgent communication establishes a communication path with the base station (100). After the establishment, the mobile station (200a) which has transmitted the urgent communication performs communication according to the normal communication procedure.

Title: Economic low-head hydro and tidal power turbine
Inventor: STABINS PETER ANDREW
IPC: F03B13/26
Filed: 2006-01-11
Abstract: A reaction turbine system for low-head hydro and tidal power is disclosed. The system consists of multiple Darrieus type turbine sections attached in series along a single horizontal rotating shaft. The Darrieus blades are long, rectangular, perpendicular to fluid flow and have an airfoil shaped cross-section. The blades in each Darrieus section are offset from the blades in the other sections. This greatly reduces the torque pulsation typical of a Darrieus turbine while keeping the simplicity of straight airfoil blades, the ability to generate power from multiple fluid flow directions and a high rotational speed. Such a system can be used in open bi-directional flowing water found in tidal areas or enclosed in one or more fluid flow ducts to efficiently generate low-cost power from a low-head hydro site.
