Method for configurable aircraft USB power level management
First Claim
1. A power distributing system in an aircraft, the system comprising:
- a plurality of passenger seats of the aircraft, where a seat of the plurality of seats comprises;
a charging module, wherein the charging module is configured to (i) supply power to a connected device by way of a USB port and (ii) perform a handshake procedure with the connected device, wherein the handshake procedure comprises receiving an indication of both (i) a first power level to charge the connected device and operate the connected device and (ii) a second power level to operate the connected device but not charge the device;
a passenger control unit (PCU) coupled to the charging module, wherein the passenger control unit is configured to determine a supplied power level for the connected device, based on at least one of the indicated first power level and the second power level; and
a power supply configured to supply power to the at least one charging module based on the supplied power level.

Abstract
Within examples, systems for power distribution within the cabin of an aircraft are provided and methods for operation. The system includes a passenger seat of the aircraft. The passenger seat includes a charging module. The charging module is configured to supply power to a connected device of the passenger seat. The passenger seat also includes a passenger control unit (PCU) coupled to the charging module. The passenger control unit is configured to determine a power requirement for the connected device. Additionally, the passenger seat is associated with a seat grouping of the aircraft. The seat grouping of the aircraft includes at least one passenger seat. Further, the power distribution system includes a power supply configured to supply power to at least one charging module based on the determined power requirement.

11. A method of distributing power in an aircraft, the method comprising:
-
providing a device connection via a USB port of a charging module at a passenger seat, wherein the device connection is (i) configured to supply power to a connected device and (ii) perform a handshake procedure with the connected device, wherein the handshake procedure comprises receiving an indication of both (i) a first power level to charge the connected device and operate the connected device and (ii) a second power level to operate the connected device but not charge the device; determining a supplied power level for a connected device with a passenger control unit (PCU) of the passenger seat, wherein the supplied power level is based on at least one of the indicated first power level and the second power level; and
supplying power to at least one charging module based on the determined supplied power level via a power supply. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A method of distributing power in an aircraft, the method comprising:
-
assigning passenger seats of an aircraft to a plurality of seat groups, wherein for the plurality of seat groups; supplying power to a passenger control unit (PCU) of a plurality of passenger seats via a power supply, determining a priority for a plurality of connected devices within the group via a master PCU, providing power to a respective PCU of the group based on the determined priority via the master PCU; and for a plurality of passenger seats; providing a device connection via a USB port of a charging module at the passenger seat, wherein the device connection is (i) configured to supply power to a connected device and (ii) perform a handshake procedure with the connected device, wherein the handshake procedure comprises receiving an indication of both (i) a first power level to charge the connected device and operate the connected device and (ii) a second power level to operate the connected device but not charge the device, determining a supplied power level for a connected device with the PCU of the passenger seat, communicating the power requirement from the PCU of the passenger seat to the master PCU, and supplying power provided by the power supply to at least one charging module.
