Oscillator system for detecting a selected one of a plurality of tuned circuits

摘要: The system of the present invention allows transmission information and data across a gap, for example, from steering wheel an automobile to column, without any physical connection between source or gathering circuit. Furthermore, requires no power. utilizes principle that oscillator circuit is loaded by inductively coupled tuned oscillate at approximately same frequency. Loading causes L-C loop voltage amplitude decrease. Using first selectively switched multiple frequencies, frequencies oscillator, logic determining which several running produces decrease in voltage, provides be transmitted gap gatherine
