SGER PROPOSAL 0414020 - George C. Lee, SUNY-BuffaloABSTRACTThis proposal is to develop a new 3D jerk sensor for extraction of temporal characteristics at (tangential acceleration), an (normal acceleration), ? (temporal torsion) and (temporal curvature) for seismic ground motion and structural response analysis. The new sensor is based on an innovative coupled electro-mechanic oscillator. The output of the oscillator is directly proportional to the measured jerk (derivative of acceleration). This new approach overcomes the difficulty of differential circuitry in high frequency resonance, amplitude and phrase measurement error. And the sensor itself does not require external power for operation, which reduces the noise from the electrical sources.

SGER方案0414020 -乔治C.李，纽约州立大学布法罗ABSTRACTThis建议是开发一种新的三维加加速度传感器的时间特性提取（切向加速度），（法向加速度），？（时间扭转）和（时间曲率）用于地震地面运动和结构反应分析。新的传感器是基于一个创新的机电耦合振荡器。振荡器的输出与测量的加加速度（加速度的导数）成正比。这种新方法克服了差动电路在高频谐振、幅值和相位测量误差方面的困难。传感器本身不需要外部电源进行操作，这降低了来自电源的噪声。
