    • Methods and apparatus implementing techniques for asymmetrical communication in prepayment metering. In general, in one aspect, the techniques provide a utility system (100) that includes a distribution network (102) for distributing a resource to a customer. The system includes a meter (104) for metering the resource and for connecting and disconnecting a supply of the resource distributed to the customer. The meter (104) includes a control system (106) for maintaining an account of the customer and for controlling distribution of the resource based on account information. The meter (104) includes a first communication system (108) for sending, over a first medium, information from the prepayment meter (104) to the control system (106). The meter (104) includes a second communication system (110) for sending, over a second medium, information from the control system (106) to the prepayment meter (104), wherein the information includes signals for disconnecting or connecting the supply of the resource distributed to the consumer.
    • 方法和设备实现预付费计量中不对称通信的技术。 通常,在一个方面,该技术提供了一种公用事业系统(100),其包括用于将资源分配给客户的分配网络(102)。 该系统包括用于计量资源并用于连接和断开分配给客户的资源的供应的计量器(104)。 仪表(104)包括一个控制系统(106),用于维护客户的帐户并根据帐户信息来控制资源分配。 仪表(104)包括第一通信系统(108),用于在第一介质上从预付费计量器(104)向控制系统(106)发送信息。 仪表(104)包括第二通信系统(110),用于通过第二介质将信息从控制系统(106)发送到预付费计量器(104),其中所述信息包括用于断开或连接 资源分配给消费者。

    • A broadband omni-directional bicone antenna. The antenna can comprise conductive surfaces of conical voids provided within a solid dielectric structure. The outside surface of the solid structure can support a radio frequency (RF) lens geometry operable for beam forming. The beam forming can modify the elevation pattern of the electromagnetic radiation from the bicone antenna. The solid dielectric structure may be machined or molded from a single piece of material. The conical voids provided within the solid structure can be metallized to provide conductive bicone radiators. The outer surface beam shaping lenses can be zoned or continuous and can provide elevation patterns with increased gain, cosecant squared falloff, or various other patterns. The beam shaping lens may be formed from any low-loss dielectric. Alternatively, the lens may be formed from a less dense material such as dielectric foam that can support radial conductive beam forming vanes.
    • 宽带全向双向天线。 天线可以包括设置在固体电介质结构内的锥形空隙的导电表面。 固体结构的外表面可以支持用于波束形成的射频(RF)透镜几何形状。 波束形成可以修改来自二极管天线的电磁辐射的仰角图。 固体电介质结构可以由单片材料加工或模制。 提供在固体结构内的锥形空隙可以被金属化以提供导电的二元散热器。 外表面光束整形透镜可以划分或连续,并且可以提供具有增加的增益,舒适平方衰减或各种其它图案的高程图案。 光束整形透镜可以由任何低损耗电介质形成。 或者,透镜可以由较不致密的材料形成,例如可以支撑径向导电波束形成叶片的电介质泡沫。
