First Claim
Patent Images
1. A non-transitory machine-readable storage medium encoded with instructions executable by a processor, the machine-readable storage medium comprising instructions to:
- obtain an impedance measurement at each key position of a connection socket;
detect a plugged cable at a key position based on the obtained impedance measurement;
in response to the detected plugged cable at the key position, determine an assigned power level associated to the key position;
deliver a power through the plugged cable according to the determined assigned power level based on a logic state that represents assigned bits of data to signal a level of power to be delivered to the key position.

Abstract
Examples disclose a computing system comprising a host device with a connection socket to support multiple types of cables by detecting a first key position and a second key position for determination of the type of cable. Further, the computing system comprises a switching circuit to determine a logic state of each of the key positions. Additionally, the switching circuit is to deliver power associated with the type of cable based on the logic states of the key positions.
