Abstract

An electrical power distribution system has fixed stations with AC power to DC power conversion circuitry at these stations. The converter(s) are switchable ON/OFF at outlet ports or sockets where the socket configuration permits. Standardized DC sockets accommodate a variety of voltage requirements typical of portable digital devices. In some embodiments feedback circuitry is provided to regulate the power to these devices in accordance with parameters programmed in the portable devices or in the sensing circuitry provided at each station.

Claims

1. An electrical power distribution system, comprising:

an AC to DC converter for providing low voltage DC power;

at least one USB port electrically coupled to said AC to DC converter by a voltage regulator, wherein said USB port is configured to provide a DC voltage line connection but not a data line connection; and

a switch coupled between said AC to DC converter and said USB port to selectively energize said USB port when a plug is inserted;

wherein said switch is configured to turn the AC to DC converter on when a plug is inserted into said USB port, and turn the AC to DC converter off when no plug is inserted into said USB port.

2. The system according to claim 1, further including an indicator activated electrically by said switch for visually indicating the electrical condition of said USB port.

3. The system according to claim 2, wherein the indicator is an LED indicator.

4. The system according to claim 1, wherein said switch comprises a moveable support, whereby inserting a plug into said USB port energizes said AC to DC converter and provides DC voltage to the USB port.

5. The system according to claim 1, wherein said USB port is configured to provide various DC voltages for powering devices having various voltage requirements.

6. An electrical power distribution system, comprising:

AC to DC converter for providing low voltage DC power;

a DC outlet socket electrically coupled to said AC to DC converter by a voltage regulator,

a control circuit configured to receive a feedback signal from a device connected to the DC outlet socket,

wherein, based on the feedback signal from the device, the control circuit signals the voltage regulator to output a specified voltage to the DC outlet socket;

whereby various DC voltages are available at the DC outlet socket for powering devices having various voltage requirements.

7. The system of claim 6, wherein said DC outlet socket is a USB port or a FIREWIRE port.

8. The system according to claim 6, further including a switch coupled between said AC to DC converter and said DC outlet socket for selectively energizing said DC outlet socket;

wherein said switch comprises a moveable support, whereby inserting a plug into said DC outlet socket energizes said AC to DC converter and provides DC voltage to the DC outlet socket.

9. The system according to claim 8, further including an indicator activated electrically by said switch for indicating visually the electrical condition of said DC outlet socket.

10. The system according to claim 8, further including a manually moveable closure for said DC outlet socket, said switch being responsive to manual movement of said moveable closure from closed to open for energizing said DC outlet socket.
