Source device detection may be performed for a variety of types of connectors such as cables or board/substrate connectors across which a DC voltage or stable presence signal is normally supplied during connections when the power signal of the connector is not present. An alternating power source is coupled to a capacitor of known capacitance via a switch. The capacitor is in series with an effective capacitance of a sink device, a connector, and a source device. When the switch is open, the voltage between the capacitor and the effective capacitor is read to determine if a source device is present and On, and when closed, if the source device is present and Off or in Stand-By, or not present. The methods, systems, and apparatuses described include tunability for the capacitor based on temperature and effective capacitance variations."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Source device detection","description":"Methods, systems, and apparatuses are described for source device detection.
