    • A device and apparatus for determining wind conditions around a sailboat. The device includes means for receiving a measured wind angle and wind speed readings from a wind sensor attached to the sailboat and readings of boat heading and boat speed through the water, means for storing wind angle correction data, a computing unit for computing a corrected wind angle reading using the measured wind angle reading, the boat speed reading and the wind angle correction data and for computing a wind direction using the corrected wind angle reading and the boat heading reading, and means for displaying the wind direction. The device additionally includes input means for receiving a wind direction error tack to tack, means for determining the current tack state of the sailboat using the measured wind angle reading, and means for modifying the correction data. Thus, powerful and intuitive correction of wind direction readings is possible.
    • 一种用于确定帆船周围的风况的装置和装置。 该装置包括用于从附接到帆船的风传感器接收测量的风角和风速读数的装置,以及通过水的船的航向和船速的读数,用于存储风角校正数据的装置,用于计算校正风的计算单元 使用测量的风角读数,船速读数和风角校正数据的角度读数,以及使用校正的风角读数和船的航向读数来计算风向,以及用于显示风向的装置。 该装置还包括用于接收风向误差粘性的输入装置,用于使用测得的风角读数确定帆船的当前粘着状态的装置,以及用于修改校正数据的装置。 因此,强大和直观的风向读数校正是可能的。

    • A method of wirelessly networking a system of at least first and second communication nodes includes obtaining a common power source for the at least first and second communication nodes, switching on the common power source, and establishing a power-up time. Each of the first and second communication nodes is capable of tracking the time since the power-up time. The method includes sending a start signal from one of the first and second communication nodes, wherein the start signal occurs after the power-up time and includes at least information of the elapsed time since the power up time. The method includes networking the other of the first and second communication nodes with the one of the first and second communication nodes sending the start signal, if the elapsed time of the other of the first and second communication nodes approximately matches the elapsed time provided in the start signal.
    • 至少第一和第二通信节点的系统的无线联网的方法包括获得用于所述至少第一和第二通信节点的公共电源,接通公共电源以及建立上电时间。 第一和第二通信节点中的每一个能够跟踪从上电时间起的时间。 该方法包括从第一通信节点和第二通信节点之一发送起始信号,其中起始信号在上电时间之后发生,并且至少包括从上电时间起经过的时间的信息。 该方法包括:如果第一和第二通信节点中的另一个的经过时间大约与第一和第二通信节点中提供的经过时间大致匹配,则将第一和第二通信节点中的另一个与发送开始信号的第一和第二通信节点中的一个进行联网 启动信号。

    • A heat exchanger including a first header, a second header, and a third header. The third header includes a first plate including a generally planar face and a second plate including a generally planar face parallel to the planar face of the first plate and joined to the planar face of the first plate. The second plate includes an arcuate recess that extends from the planar face of the second plate to at least partially define a flow conduit between a first tube and a second tube. The arcuate recess has a radius of curvature measured from an axis generally parallel to the planar faces of the first and the second plates, and the axis is located within a first plane generally parallel to and midway between first and second opposing flat broad sides of the first tube and the second tube.
