SYSTEM AND METHOD OF DETECTING A PLUG-IN TYPE BASED ON IMPEDANCE COMPARISON

A particular method includes determining, at an electronic device having a plug-in port, a plug-in type of an accessory connected to the plug-in port based on a comparison of an alternating current (AC) impedance at the plug-in port to a direct current (DC) impedance at the plug-in port.

Zusammenfassung:	A particular method includes determining, at an electronic device having a plug-in port, a plug-in type of an accessory connected to the plug-in port based on a comparison of an alternating current (AC) impedance at the plug-in port to a direct current (DC) impedance at the plug-in port. Cette invention concerne un procédé consistant à déterminer dans un dispositif électronique comprenant un port de raccordement, un type de dispositif enfichable d'un accessoire enfiché dans le port de raccordement sur la base d'une comparaison d'une impédance de courant alternatif (AC) sur le port de raccordement à une impédance de courant continu (CC) sur le port de raccordement.
