    • A pen transcription system and method for using the same are disclosed. The pen transcription system includes a receiver having first and second acoustical sensors mounted on a planar base and separated from one another, an EM detector, and a controller. The first and second acoustical sensors detect an acoustical signal emitted by a moveable signal source. The EM detector detects an EM signal that is synchronized with the acoustical signal. The controller measures the difference in time of detection between the EM signal and the acoustical signals detected by the first and second acoustical sensors. The acoustical sensors include a detector and a housing surrounding the detector, the housing having an aperture defined by an axis. The acoustical sensor has a reception function that is symmetrical about the axis and the axis is substantially perpendicular to the base surface.
    • 公开了一种笔转录系统及其使用方法。 笔转录系统包括具有安装在平面基底上并且彼此分离的第一和第二声学传感器,EM检测器和控制器的接收器。 第一和第二声学传感器检测由可移动信号源发出的声音信号。 EM检测器检测与声信号同步的EM信号。 控制器测量EM信号和由第一和第二声学传感器检测的声音信号之间的检测时间差。 声学传感器包括检测器和围绕检测器的壳体,壳体具有由轴限定的孔。 声学传感器具有关于轴对称的接收功能,并且该轴基本上垂直于基面。
