馋死 PPT研究院 POWERPOINT ACADEMY * * There is always the possibility to set a manually emergency call in any case of need. Optionally, data can be transmitted continuously to a command centre for use on professional emergency personnel. Another very helpful function is integrated in the innovative waistcoat: Heating elements are turned on if skin temperature is detected to have dropped to dangerous levels. 3. How do they work? The unit uses a ARM chip housed in the STAM32F4-Discovery board and is used in conjunction with an FFT library to process incoming sound and look at particular frequencies in the signal and how their magnitudes are proceeding. This allows the system to selectively identify a particular input. If it is above a certain threshold it provides feedback to the user about the detected emergency service. 参考译文： 电子电工技术应用 VCEC 生命体征控制和紧急呼救背心 它看起来就像你在任意一家外用品店可买到的背心一样，但是，生命体征控制和紧急呼救背心的作用远非如此。它可以监测穿者的重要生命体征，并能自动发出紧急呼救。 全方位警笛探测器 这是一个安装在汽车仪表板、交通信号灯或收费桥梁上的装置，它能探测该区域需提供的紧急服务并提供反馈。该探测器安装了4个微型麦克风。 该背心是老年人和医疗高危人群的日常保镖，使他们能够安心享受户外活动。该背心还可连续监测一些重要的人体功能，如心率，呼吸频率和体温。传感器收集运动和位置的数据。如果控制中心监测到紧急情况，就会以无线电、手机、视觉和听觉等各种形式发出紧急呼救。该装置传送出实时生命体征数据和所在的位置，以便做出初步诊断和定位。用红色LED灯做成的箭头会有效地告诉用户警笛的方向，而小液晶屏会显示简单易懂的图标来代表警车、救护车或救火车等不同的警报类型，来提醒和通知用户。该装置使用电池组来提供电源，电池容量可供本机工作数小时。为本机充电的连接器是标准的Ipod或Iphone电源插座，无需专用的电缆类型 如有必要，随时都可以手动发出紧急求助信号。该背心还可选择将数据连续地传输到一个指挥中心，供专业应急人员使用。该创新性的背心还有一个非常有用的功能：如果检测到人的体温下降到危险的温度，自动供热部件会启动。该装置采用了ARM芯片、STM32F4电子板和快速傅里叶变换算法库来处理接收到的音频。 分析声音的频率和音量来识别一个特定的音谱形式。这样该系统就能有选择地辨认特定的输入。当该装置确认收录到特定的警笛声音后，会立即将检测到的应急服务信息通知使用者。  Words and Expressions 1. vital ---- urgently needed; absolutely necessary e.g. The port is vital to supply relief to millions of drought victims 2. monitor --- check or record e.g. If we can know their frequency we will monitor their talking. 3. suffer from --- have a kind of disease e.g. I often suffer from unaccountable headaches. 4. in case of --- if, by any possibility e.g. I told them what each was to do in case of an emergency. 5. transmit --- s
