摘要： An antenna comprises a conductive helix (10) positioned parallel to a ground plane (12). One end (14) of the helix is coupled to the ground plane (12), while the other end (16) is left open. Radio frequency signals (20) are fed (18) into the open end of the helix to excite the antenna and radiate the radio frequency signal.

摘要： A paging receiver device and method are disclosed in which analog information transmitted from an external source such as a paging transmitter are received and decoded. The analog information includes at least one voice message. The voice message is recovered, digitized, and stored in one of a plurality of message slots in a memory of the paging receiver. In response to a paging user's request, the digitized stored message is recalled from memory, reconverted from digital information to analog information, and used to produce audible voice information being a replica of the original analog voice message.
摘要翻译：公开了一种寻呼接收机设备和方法，其中接收和解码从诸如寻呼发射机的外部源发送的模拟信息。模拟信息包括至少一个语音消息。语音消息被恢复，数字化并存储在寻呼机的存储器中的多个消息时隙之一中。响应于寻呼用户的请求，从存储器调用数字化的存储消息，从数字信息重新转换为模拟信息，并且用于产生作为原始模拟语音消息的副本的可听话音信息。

摘要： A fiber optic based security system is disposed on or in a structure such as a wall, roof, floor, ceiling, container, and/or ground. The security system contains an optical cable having first and second ends and an interface unit connected to both ends of the optical cable. The interface unit generates a specific light signal injected into the first end. The interface unit receives the specific light signal from the second end after the specific light signal propagates through the optical cable. The interface unit then determines if the specific light signal received falls within a given threshold and outputs an alarming signal indicating if the specific light signal received falls outside of the given threshold. An alarm system receives the alarming signal from the interface unit. The alarm system is activated if the interface unit indicates that the specific light signal falls outside of the given threshold.
摘要翻译：基于光纤的安全系统设置在诸如墙壁，屋顶，地板，天花板，容器和/或地面的结构上或其中。该安全系统包括具有第一端和第二端以及连接到光缆两端的接口单元的光缆。接口单元产生注入到第一端的特定光信号。接口单元在特定光信号通过光缆传播之后从第二端接收特定的光信号。然后，接口单元确定接收到的特定光信号是否落在给定阈值内，并输出指示接收到的特定光信号是否落在给定阈值之外的报警信号。报警系统从接口单元接收报警信号。如果接口单元指示特定光信号超出给定阈值，则报警系统被激活。
