Patent ID: 7840740

Claim:
A docking device comprising: a first connector for exchanging data with a media device, one or more second connectors for delivering data to a media supporting device, one or more sensors for detecting when the media supporting device is connected to the one or more second connectors, wherein the docking device is configured to hold the media device, the sensor further comprising: a resistor network operative to provide a first resistance value when the media supporting device is not connected to the one or more second connectors and a second resistance value when the media supporting device is connected to the one or more second connectors, the first resistance value operative to place the media device in a mode to not deliver data to the media supporting device, and the second resistance value operative to place the media device in a mode to deliver data to the media supporting device; and circuitry that pulses a first conductor in the first connector in response to detecting when the media supporting device is connected to the one or more second connectors, the pulse operative to cause the media device to query a second conductor in the first connector to determine a value associated with the resistor network.
