    • An in-line pipe inspection tool has one or more inspection platforms (28, 30) which are connected to an elongate wheeled trolley by link arms (20 to 26). The trolley unit (10, 12) has drive means for driving the point of connection of the first link arm (20, 22) to the trolley (10) relative to the point of connection of the second link arm (24, 26) to the trolley (12), thereby to move the inspection platforms (28, 30) in a direction perpendicular to the direction of elongation of the trolley (10, 12). Thus the inspection platforms (28, 30) are movable which is relative to the trolley (10, 12) to permit the tool to be adapted to pipelines of different diameters. Moreover, the platforms (28, 30) preferably have permanent magnets which contain a rotatable magnet. The rotatable magnet permits the net magnetic field generated by the platform to be varied.
    • 在线管道检查工具具有一个或多个通过连接臂(20至26)连接到细长轮式手推车的检查平台(28,30)。 推车单元(10,12)具有驱动装置,用于相对于第二连杆臂(24,26)的连接点将第一连杆臂(20,22)与手推车(10)的连接点相对于 所述手推车(12),从而使所述检查平台(28,30)沿与所述手推车(10,12)的伸长方向垂直的方向移动。 因此,检查平台(28,30)可相对于台车(10,12)移动,以允许工具适应于不同直径的管道。 此外,平台(28,30)优选地具有包含可旋转磁体的永磁体。 可旋转的磁体允许由平台产生的净磁场变化。

    • Systems and methods for determining an optimal range of frequencies of electromagnetic waves are described. In some embodiments, mobile voice communications devices measure average power received from certain ranges of such frequencies, each range associated with a communications service provider. A cost may be associated with each range. An optimal range of frequencies may be determined based on these factors. Each device may also receive a set of data identifying the location of the device. Each device may transmit one or more communications signals to a CIP with such measurements and location information, and some of this information may be stored in a database.
    • 描述用于确定电磁波的最佳频率范围的系统和方法。 在一些实施例中,移动语音通信设备测量从这种频率的某些范围接收的平均功率,每个范围与通信服务提供商相关联。 成本可能与每个范围相关联。 可以基于这些因素来确定最佳的频率范围。 每个设备还可以接收标识设备位置的一组数据。 每个设备可以向具有这样的测量和位置信息的CIP发送一个或多个通信信号,并且这些信息中的一些可以被存储在数据库中。
