Abstract

A portable electronic device connected to a network for receiving electrical power from the network. The portable electronic device includes a circuit for detectingand receiving electrical power over the network, and a power converter electrically connected to the circuit for receiving the electrical power from the circuit, converting the received electrical power such that converted electrical power has power characteristics compatible with the portable electronic device.

Claims

1. A portable electronic device comprising:

a circuit coupled to a network for receiving pre-processed power not processed by said circuit and generating post-processed power processed by said circuit; and

a power converter coupled to said circuit for converting said post-processed power to converted power for providing power supply to said portable electronic device.

2. The portable electronic device of claim 1, wherein said converted power is used to charge one or more batteries coupled to said portable electronic device under a mode selected from a group consisting of a normal operating mode, a shut-off mode, a stand-by mode, a power-saving mode and a sleep mode.

3. The portable electronic device of claim 1, wherein saidcircuit is coupled to said network via one or more RJ-45 connectors.

4. The portable electronic device of claim 1, wherein said network is an Ethernet.

5. A network power splitter comprising:

a circuit coupled to a network for receiving pre-processed power not processed by said circuit and generating post-processed power processed by said circuit;

a power converter coupled to said circuit for converting said post-processed power to converted power; and

one or more power output interfaces for outputting said converted power to one or more portable electronic devices.

6. The network power splitter of claim 5 further comprising one or more network interfaces for transmitting data between saidnetwork and saidone or more portable electronic devices.

7. The network power splitter of claim 5, wherein saidcircuit is coupled to said network via one or more RJ-45 connectors.

8. The network power splitter of claim 5, wherein said network is an Ethernet.

9. A method for supplying power to a portable electronic device, comprising the steps of:

receiving pre-processed power, not processed by a circuit coupled to said portable electronic device, from a computer network;

generating post-processed power processed by said circuit;

and

converting said post-processed power to converted power according to a voltage requirement of said portable electronic device.
