Abstract
Abstract A connector adapter enabling power to be provided to a portable electronic device through a combined power and signal connector. In a specific example system, power for a portable electronic device is provided through a serial data connector. A serial I/O cable has a device end and a computer end. The computer end of the cable has a connector that includes a socket for receiving a power jack from a separate power supply. The adapter enables external power to be connected when the portable electronic device is operating alone. The adapter is similar to the computer end of the I/O cable, comprising a serial data connector that includes a socket for receiving a power jack from the separate power supply.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
97 words
An adapter comprising: a first connector, the first connector adapted to receive a power connector; a second connector, the second connector having at least two contacts for power, the second connector adapted to mate with a signal connector, the signal connector having at least two contacts for power and at least one contact for a signal other than power; and the first connector having contacts connected only to the power contacts of the second connector, thereby enabling power to be transmitted through the second connector to the signal connector without any signal connections to the second connector.
Claim 2
Dependent Claim
97 words
An adapter comprising: a first connector, the first connector adapted to receive a power connector; a second connector, the second connector having at least two contacts for power, the second connector adapted to mate with a signal connector, the signal connector having at least two contacts for power and at least one contact for a signal other than power; and the first connector having contacts connected only to the power contacts of the second connector, thereby enabling power to be transmitted through the second connector to the signal connector without any signal connections to the second connector.
Claim 3
Independent Claim
137 words
A method of providing power to an electronic device, the electronic device including a signal connector, the signal connector having at least one contact adapted to conduct a signal other than power: connecting, on a first connector on an adapter, at least two contacts to power; connecting, in the adapter, contacts in a second connector, only to the contacts in the first connector that are connected to power, so that contacts in the second connector are only connected to power and are not electrically connected to any signal lines other than power; and connecting the second connector to the signal connector on the electronic device, so that some contacts in the signal connector are electrically connected to power and all other contacts in the signal connector are not electrically connected to any signal lines other than power.
Claim 4
Independent Claim
137 words
A method of providing power to an electronic device, the electronic device including a signal connector, the signal connector having at least one contact adapted to conduct a signal other than power: connecting, on a first connector on an adapter, at least two contacts to power; connecting, in the adapter, contacts in a second connector, only to the contacts in the first connector that are connected to power, so that contacts in the second connector are only connected to power and are not electrically connected to any signal lines other than power; and connecting the second connector to the signal connector on the electronic device, so that some contacts in the signal connector are electrically connected to power and all other contacts in the signal connector are not electrically connected to any signal lines other than power.
