    • An apparatus includes a conductive plate operable to generate a reference signal and a shield configured to surround at least a portion of the conductive plate and to attenuate at least a portion of a horizontal electromagnetic signal. The apparatus also includes an electrode configured to be electrically coupled to the shield and to a ground, where the electrode is responsive to a vertical electromagnetic signal, and the vertical electromagnetic signal generated by a subsurface earth formation in response to an electroseismic or seismoelectric conversion of a passive electromagnetic source signal. The apparatus also includes an amplifier comprising a first input and a second input, where the first input is configured to electrically couple to the conductive plate and the second input is configured to electrically couple to the electrode.
    • 一种装置包括可操作以产生参考信号的导电板和被配置为围绕导电板的至少一部分并且衰减水平电磁信号的至少一部分的屏蔽。 该装置还包括电极,其被配置为电耦合到屏蔽和接地,其中电极响应于垂直电磁信号,以及由地下地层响应于电地震或地震电转换产生的垂直电磁信号 被动电磁源信号。 该装置还包括放大器,其包括第一输入端和第二输入端,其中第一输入端被配置为电耦合到导电板,而第二输入端被配置为电耦合到电极。

    • A system for distributing electronic messages amongst a plurality of users wherein the system comprises a server and a plurality of client devices in communication by means of at least one communications network. A message management module maintains a message storage device, and provides a message user interface by which messages in the storage device can be displayed or accessed by said client devices. The users each belong to at least one of a plurality of user groups, and, upon receipt of an original message from a first user via a first client device in respect of a first user group, the message management module causes the message to be sent to client devices associated with other users belonging to said first group. Upon receipt of a reply message from at least one of said other users via a respective client device, the message management module causes the, or each, reply message to be displayed on said message user interface in association with said original message.
    • 一种用于在多个用户之间分发电子消息的系统,其中所述系统包括通过至少一个通信网络进行通信的服务器和多个客户端设备。 消息管理模块维护消息存储设备,并提供消息用户界面,通过该消息用户界面可以由所述客户端设备显示或访问存储设备中的消息。 每个用户各自属于多个用户组中的至少一个,并且在相对于第一用户组经由第一客户端设备从第一用户接收到原始消息时,消息管理模块使得该消息被发送 涉及与属于所述第一组的其他用户相关联的客户端设备。 在通过相应的客户端设备从至少一个所述其他用户接收到回复消息时,消息管理模块使得或者每个应答消息与所述原始消息相关联地显示在所述消息用户界面上。
