    • A glass breakage detector (100) having an acoustic transducer (102) for sensing first acoustic waves (130) and for providing a first analog signal (110) representative of the received first acoustic waves (130), an analog to digital converter circuit (104) adapted to convert the first analog signal (110) to a digital signal (112), processing circuitry (106) adapted to process the digital signal (112) to determine if the received first acoustic waves (130) are a result of glass breakage and generate an alarm signal (116) when it is determined that the received first acoustic waves (130) are a result of glass breakage, and a memory circuit (108), wherein the processing circuitry (106) is adapted to cause the memory circuit (108) to store the digital signal (112) for subsequent retrieval and analysis.
    • 一种具有用于感测第一声波(130)并用于提供代表所接收的第一声波(130)的第一模拟信号(110)的声换能器(100)的玻璃破损检测器(100),模数转换器电路 104),其适于将所述第一模拟信号(110)转换为数字信号(112),适于处理所述数字信号(112)以确定所接收的第一声波(130)是否为玻璃的结果的处理电路(106) 当确定接收到的第一声波(130)是玻璃破裂的结果时,断裂并产生报警信号(116),以及存储器电路(108),其中处理电路(106)适于引起存储器 电路(108)以存储数字信号(112)用于随后的检索和分析。
