发明名称 METHOD AND APPARATUS FOR DETECTING PRESENCE OF VEHICLE USING A MAGNETIC SENSOR EMPLOYING A MAGNETO-RESISTIVE EFFECT
摘要 Method using raw signal from magneto-resistive sensor through the use of recent variance (RV) of raw signal (RS) for first-capture of first time RV crosses variance detect, second-capture start enable for first time when RS crosses above raw detect and RV above variance detect, third-capture ending time when RS crosses below raw undetect and RV below variance undetect. Starting and ending times are products of the process, often used for traffic flow counts. Apparatus supporting this method as a processor and/or a vehicular sensor node.
