    • A system and method for a vertical axis wind turbine (VAWT) is described which can provide the basis for a new and improved wind turbine design suitable for a range of different power classes such as from 4 kilowatts to 10 megawatts. A vertical blade of chord length C is attached to a central hub via a main support strut of chord length C. The main support strut comprises two sections: a blade-support-section and a counterweight-support-section. Both the blade-support-section and the counter-weight-support-section have a blunt leading edge and a tapered trailing edge with the profile reversing either side of the hub axis. Two control struts comprising aerodynamic profiles support the blade wherein one control strut connects to the upper surface of the main support strut and the other control strut connects to the lower surface of the main support strut hub. The main support strut and the control struts provide lift to the wind turbine and reduce drag. The vertical blade and the main support strut comprise an integrated differential strain gauge, which is linked to a central controller and provides real time data on the integrity of the blade and strut.
    • 描述了用于垂直轴风力涡轮机(VAWT)的系统和方法,其可以为适用于一系列不同功率等级(例如4千瓦至10兆瓦)的新的和改进的风力涡轮机设计提供依据。 弦长C的垂直叶片通过弦长C的主支撑支柱连接到中心毂。主支撑支架包括两个部分:叶片支撑部分和配重支撑部分。 叶片支撑部分和对重支撑部分都具有钝的前缘和锥形的后缘,其轮廓反转轮毂轴线的任一侧。 包括气动轮廓的两个控制支柱支撑叶片,其中一个控制支柱连接到主支撑支柱的上表面,另一个控制支柱连接到主支撑支柱毂的下表面。 主要支撑支柱和控制支柱为风力发电机提供电梯并减少阻力。 垂直叶片和主支撑支柱包括集成的差分应变计,其与中央控制器相连,并提供关于叶片和支柱完整性的实时数据。

    • The invention describes a selection and arbitration method for reading a population of RFID transponders (tags). The transponders are selected or de-selected individually, or in one or more groups, using one or more command signals from a reader. The command signals from the reader include selection or de-selection criteria for selecting or de-selecting transponders by moving them between different states by setting or resetting a command flag, such as a flip-flop, in the transponders. The different transitional states include a Ready state, an Active state, a Standby state, a Singulated state and a Quiet state.
    • 本发明描述了一种用于读取大量RFID应答器(标签)的选择和仲裁方法。 使用来自读取器的一个或多个命令信号,单独地或者在一个或多个组中选择或取消选择应答器。 来自读取器的命令信号包括通过在转发器中设置或重置诸如触发器之类的命令标志来在不同状态之间移动来选择或取消选择转发器的选择或取消选择标准。 不同的过渡状态包括就绪状态,活动状态,待机状态,Singulated状态和Quiet状态。
