汽车安全与防盗最初的电子化开始于1994年的引擎防盗(IMMO),恩智浦半 导体(当时的飞利浦半导体)作为第一家半导体公司把RFID的电子标签技术成功 的应用于汽车电子引擎锁:通过汽车与钥匙间的125kHz的无线通讯实现电子身 份识别,来判断启动汽车引擎。这一技术极大的提高了汽车的安全性,很快就在 欧洲以及北美地区广泛应用,并在短短几年时间内使欧洲的汽车失窃率大幅降低 了90 ,因而成为整个欧洲的汽车标准配置(Automotive safety and anti-theft electronic originally began in 1994, engine anti-theft (IMMO), NXP (then Philips Semiconductors) as the first semiconductor company to RFID electronic tag technology successfully used in automotive electronic engine lock: By car keys between 125kHz and wireless communications for electronic identification, to determine start the car engine. This technology greatly improves the car' s safety, soon in Europe and North America, widely used, and in a few years time so that European auto theft rate significantly reduced by 90 , and thus the entire European automotive Standard configuration)

核磁共振(NMR)技术探测地下水是目前唯一的直接找水的地球物理方法。与传统的地球物理方法相比具有高分辨力,高效率,信息量丰富和解唯一性等优点。利用核磁共振地下水探测系统可以高效率地进行区域水文地质调查,确定找水远景区,圈定地下水在三维空间内的分布,进而可靠地选定水井位置等。但是由于水中氢核产生的核磁共振信号的幅度小(纳伏级),要求探测系统的灵敏度高,将引入大量的自然和人为噪声,导致采集信号的信噪比低,解释结果不清楚。 本文用LMS自适应算法提高MRS信号的信噪比,用Hilbert变换提取MRS信号的包络信号,用线性拟合提取水文地质参数并通过仿真实验结果,验证了本文提出的数据处理方法的有效性和准确性。 (Nuclear magnetic resonance (NMR) technique to the detection of direct water division is the only geophysical method to find water. Compared with conventional high-resolution geophysical methods, efficient, informative unique advantages of reconciliation. Groundwater exploration using nuclear magnetic resonance system can efficiently carry out the regional hydrogeological investigation to determine the prospective areas to find water, delineation of ground water distribution in three-dimensional space, and then reliably the location of the selected wells. However, because the water proton NMR signal amplitude generated by small (Na V level), requiring high sensitivity detection systems, will introduce a large number of natural and man-made noise, resulting in low signal to noise ratio acquisition, interpretation of results is not clear. In this paper, LMS adaptive algorithm improves the MRS signal to noise ratio, with the Hilbert transform to extract the signal envelope MRS signal ext)
