ABSTRACT:
Systems and methods include a circuit for detecting the insertion of a component into a docking station, e.g., an audio plug. When the component is inserted into the docking station, an electronic switch can be opened. When the switch is opened, a detector (e.g., monostable multivibrator) for detecting a change in state of the switch can be activated. Responsive to the detected change in state, the detector can issue a signal to a control device. Responsive to the signal, the controller can look to a resistive identification circuit and, based on its resistance, determine whether the component has just been inserted or removed from the docking station.
