    摘要： A method for providing an alarm for a window comprises calculating a first distance between a detector mounted within a movable portion of the window and a window frame edge and calculating a second distance between the detector and the window frame edge. The method further comprises determining whether the movable portion of the window has remained stationary for more than a predetermined time period based on the first distance and the second distance and, if the movable portion has remained stationary for more than the predetermined time period, storing the second distance in a memory, placing the security apparatus into an active alarm state, calculating a third distance observed by the detector, determining a change between the third distance and the second distance, determining whether the change exceeds a predetermined distance, and generating an alarm signal if the change exceeds the predetermined distance.

    摘要： A device includes a controller. An input is coupled to the controller, the input having a set of wires to couple to a doorbell to receive an AC signal when the doorbell is actuated. An analog to digital converter is coupled to the input to convert the received AC signal to a digital signal and coupled to the controller to provide the digital signal to the controller. A transmitter is coupled to the controller to wirelessly transmit signals from the controller representative to actuation of the doorbell. An enclosure contains the controller, input, analog to digital converter and transmitter and has an opening to provide a passage outside the enclosure for the set of wires. The controller may be programmable via an optical signal and may provide alerts responsive to a temperature sensor.

    摘要翻译： 设备包括控制器。 输入耦合到控制器，输入具有一组电线以耦合到门铃以在门铃被致动时接收AC信号。 模数转换器耦合到输入端，以将接收到的AC信号转换为数字信号并耦合到控制器以向控制器提供数字信号。 发射机耦合到控制器以无线地传输来自控制器代表的信号到门铃的致动。 外壳包含控制器，输入，模数转换器和变送器，并具有一个开口，用于为该组电线提供外壳外的通道。 控制器可以经由光信号来编程，并且可以响应温度传感器提供警报。
