摘要： An coin sensor utilizes time-multiplexing of LC oscillators having natural frequencies F1A, F1B, F2, and F3 to produce magnetic fields in three sets of windings. As a coin passes through the coin sensor, the LC oscillators are separately enabled in a sequence to produce a frequency profile for each set of windings. A first winding produces a frequency profile for a cross-sectional area of a coin, and a third winding produces a frequency profile for further distinguishing the relative size of a coin. A microcontroller identifies signatures points from the frequency profiles and compares the signature points with stored signatures for a multitude of coins and/or tokens.

摘要翻译：硬币传感器利用具有固有频率F1A，F1B，F2和F3的LC振荡器的时间复用来产生三组绕组中的磁场。当硬币通过硬币传感器时，LC振荡器分别使能以产生每组绕组的频率分布。第一绕组产生用于硬币的横截面积的频率分布，并且第三绕组产生用于进一步区分硬币的相对尺寸的频率分布。微控制器从频率分布中识别签名点，并将签名点与存储的许多硬币和/或令牌的签名进行比较。
