    • A method includes forming first isolation trenches in a first side of a first semiconductor-on-insulator (SOI) structure to electrically isolate multiple portions of the first SOI structure from each other. The method also includes bonding a second SOI structure to the first SOI structure to form multiple cavities between the SOI structures. The method further includes forming conductive plugs through a second side of the first SOI structure and forming second isolation trenches in the second side of the first SOI structure around the conductive plugs. In addition, the method includes removing portions of the second SOI structure to leave a membrane bonded to the first SOI structure. The isolated portions of the first SOI structure, the cavities, and the membrane form multiple capacitive micromachined ultrasonic transducer (CMUT) elements. Each CMUT element is formed in one of the isolated portions of the first SOI structure and includes multiple CMUT cells.
    • 一种方法包括在第一绝缘体绝缘体(SOI)结构的第一侧中形成第一隔离沟槽,以将第一SOI结构的多个部分彼此电隔离。 该方法还包括将第二SOI结构接合到第一SOI结构以在SOI结构之间形成多个空腔。 该方法还包括通过第一SOI结构的第二侧形成导电插塞,并在导电插塞周围的第一SOI结构的第二侧形成第二隔离沟槽。 此外,该方法包括去除第二SOI结构的部分以留下结合到第一SOI结构的膜。 第一SOI结构,空腔和膜的隔离部分形成多个电容微加工超声换能器(CMUT)元件。 每个CMUT元件形成在第一SOI结构的隔离部分之一中,并且包括多个CMUT单元。

    • Systems and methods for field data gathering and which provide flexible configuration options for a central office. The system, run from, mobile computing devices, provides a free-flowing data gathering experience while only requiring what the central office needs from the field. The central office can configure the system to accept different types of data by way of different data input means available to the mobile computing device. Only the data needed by the central office need be collected by the mobile device operator. The data format is defined by the central office and is uploaded to each of the relevant mobile computing devices for use by the operators. Once each data set has been collected by an operator, the data package with the data set is scheduled for transmission to the central office once a connection with the central office can be made.
    • 用于现场数据采集的系统和方法,并为中心局提供灵活的配置选项。 该系统从移动计算设备运行,提供了一个自由流动的数据收集体验,同时只需要中心局从现场需要的。 中央办公室可以通过移动计算设备可用的不同数据输入手段,将系统配置为接受不同类型的数据。 只有中央办公室需要的数据需要由移动设备运营商收集。 数据格式由中心局定义,并被上传到每个相关的移动计算设备供操作者使用。 一旦每个数据集已被操作员收集,与数据集的数据包一起可以一旦与中心局建立连接就被安排传送到中心局。
