摘要: The validator has a transmit coil TC for creating a magnetic field and a receive RC coil for detecting changes in the field due to the presence of a coin adjacent to the coils. The validator performs a test on each coin to provide a first parameter which is a measure of coin face area, and a second parameter which is a measure of coin resistance.
The parameters are utilised to establish the validity of the coin.摘要翻译: 验证器具有用于产生磁场的发射线圈TC和用于检测由于与线圈相邻的硬币的存在而导致的场中的变化的接收RC线圈。 验证器对每个硬币执行测试以提供作为硬币面积的度量的第一参数,以及作为硬币抵抗度量度的第二参数。 这些参数用于确定硬币的有效性。
