Abstract: A method for fabricating a plastic spherical mirror is disclosed. First, a plastic part with a mirror surface supported by a plurality of wall structures is designed. Next, a metal mold including mold for forming the plastic part according the above design specification is provided. A mirror surface of the metal mold is polished to an A1 optical grade finish. The metal mold is heated and chilled to form a curvature of the mirror surface of the metal mold. A plastic material formulation is selected and heated until a melt thereof is obtained. The melt is injected into the mold of the metal mold and the injected melt in the mold is cooled to form the plastic part. A thin layer of a reflective metal coating is deposited on the mirror surface of the plastic part and a protective overcoat is formed on the reflective metal coating.

Abstract: In one aspect, a phone-interface device determines whether a problem has occurred at a control panel by determining whether a signal from the control panel has been received, and when a signal has not been received within a period of time, the phone-interface device transmits an error message to a monitoring station. In another aspect, the control panel determines whether a problem has occurred at the phone-interface device by determining whether a signal from the phone-interface device has been received, and when a signal has not been received within a period of time, the control panel transmits an error message to a user. In another aspect, the phone-interface device contains memory to buffer data transferred between the control panel and a monitoring station. In this way, a high-speed connection between the phone-interface and the monitoring station can be accommodated while using a lower-speed connection between the phone-interface device and the control panel.

Abstract translation: 一方面，电话接口设备通过确定是否已经接收到来自控制面板的信号来确定控制面板上是否发生了问题，并且当在一段时间内还没有接收到信号时，电话接口 设备向监控站发送错误消息。 在另一方面，控制面板通过确定是否已经接收到来自电话接口设备的信号来确定在电话接口设备上是否发生了问题，并且当在一段时间内还没有接收到信号时，控制面板 面板向用户发送错误消息。 另一方面，电话接口设备包含用于缓冲在控制面板和监控站之间传送的数据的存储器。 以这种方式，在电话接口设备和控制面板之间使用低速连接的同时，可以容纳电话接口和监控站之间的高速连接。

Abstract: A aerial display system comprising inexpensive optical elements and a high brighted LCD display or similar video image display types provides floating images in an inexpensive enclosure. In the aerial display system, either an anti-reflective acrylic plastic layer or a circular polarizer is disposed proximate and parallel to a beam splitter so that the focal point of the floating image is proximate to the plastic layer or polarizer. This image position yields both a wider field of view and wider perceived field of view.

Abstract: In a security or monitoring system having a system roller and one or more sensor/transmitters, information is sent from the transmitter to the system controller in message packets. As improved message packet protocol provides a front porch pulse, a set of synchronization bits, a start bit, a set of information bits, a first stop bit, a set of error detection bits, and a second stop bit.

Abstract: In a battery-powered sensor such as a smoke detector, a passive report of unacceptable battery condition is first given while an active report of such condition is inhibited. Then, after the lapse of a period of time after the unacceptable battery condition is first detected, the active report is given.
