Abstract

A system and method for operating electronic equipment associated with a passenger seat and/or surrounding furniture in a vehicle cabin such as an aircraft cabin. According to a standard operating mode, electronic equipment is activated and/or operable without power consumption restrictions. According to a power saving operating mode, corresponding to an economy mode or a Sabbath mode, electronic equipment is inactivated and/or operable with power consumption restrictions. Operating mode selection may be via an interface unit associated with the passenger seat. In embodiments, power consumption statistics are calculated and displayed to the passenger to indicate an economy score for a flight. In embodiments, selecting power saving mode may cause the electronic equipment to perform differently during higher aircraft power demand periods as compared to lower aircraft power demand periods.

First claim

What is claimed is:

1. A system for selectable power mode operation of electronic equipment in a passenger cabin environment, comprising:
electronic equipment associated with a passenger seat in a passenger cabin, the electronic equipment for use by a passenger;
a controller operably coupled to the electronic equipment, the controller configured to operate the electronic equipment in one of a standard operating mode and a power saving operating mode; and
an interface unit communicatively coupled to the controller, the interface unit located in at least one of the passenger seat and the surrounding furniture, the interface unit including a display, and the interface unit operable to instruct the controller, based on selection input by the passenger, to operate the electronic equipment in one of the standard operating mode and the power saving operating mode;
wherein:
the electronic equipment comprises a plurality of seat actuators configured to adjust at least one seat element of the passenger seat;
when the standard operating mode of the electronic equipment is selected, the controller is configured to activate the plurality of seat actuators simultaneously to adjust the at least one seat element; and
when the power saving operating mode of the electronic equipment is selected, the controller is configured to activate the plurality of seat actuators sequentially to adjust the at least one seat element.

2. The system according to claim 1 , wherein:
the passenger cabin is in an aircraft;
aircraft performance includes higher aircraft power demand periods and lower aircraft power demand periods;
when the electronic equipment is operated in the standard operating mode, performance of the electronic equipment is the same during each of the higher aircraft power demand periods and lower aircraft power demand periods; and
when the electronic equipment is operated in the power saving operating mode, performance of the electronic equipment is reduced during the higher aircraft power demand periods as compared to the lower aircraft power demand periods.

3. The system according to claim 2 , wherein performance of the electronic equipment includes at least one of an ability to power on the electronic equipment, power draw of the electronic equipment, and available functions of the electronic equipment.

4. The system according to claim 1 , wherein:
the controller is configured to determine a power usage of the electronic equipment operating in each of the standard operating mode and the power saving operating mode of the electronic equipment;
the controller is further configured to calculate a difference between the determined power usages and communicate at least one of the determined power usages and the calculated difference between the determined power usages to the interface unit; and
the interface unit is configured to display to the passenger, via the display, at least one of the determined power usages and the calculated difference between the power usages.

5. The system according to claim 1 , wherein when the electronic equipment is operated in the power saving operating mode:
the controller is configured to determine a power usage of the electronic equipment operated in the power saving operating mode and calculate a difference between the determined power usage of the electronic equipment operated in the power saving operating mode and a known power usage of the electronic equipment operated in the standard operating mode;
the controller is further configured to communicate the calculated difference to the interface unit; and
the interface unit is configured to display the calculated difference, via the display, as at least one of a percentage and a graphic.

6. The system according to claim 1 , wherein:
the electronic equipment further comprises mood lighting and task lighting associated with the passenger seat;
when the standard operating mode of the electronic equipment is selected, the controller is configured to activate the mood lighting and allow the task lighting to be operated up to a maximum luminosity; and
when the power saving operating mode of the electronic equipment is selected, the controller is configured to inactivate the mood lighting and allow the task lighting to be operated up to a reduced luminosity less than the maximum luminosity.

7. The system according to claim 1 , wherein:
the passenger cabin is located in an aircraft;
when the standard operating mode of the electronic equipment is selected, the controller is configured to supply maximum power to the electronic equipment;
when the power saving operating mode of the electronic device is selected, the controller is configured to supply reduced power to the electronic equipment; and
the power saving mode causes the electronic equipment to perform differently during higher aircraft power demand periods as compared to lower aircraft power demand periods.

8. The system according to claim 1 , wherein the interface unit is located in or incorporated into an electronic passenger control unit associated with the passenger seat, and wherein the system further includes an indicator associated with the passenger seat configured to display an energy performance score, the indicator visible to at least one of the passenger and surrounding passengers in the passenger cabin environment.

9. A method for operating electronic equipment in a passenger cabin of an aircraft, comprising:
providing electronic equipment in an aircraft, the electronic equipment associated with a passenger seat, and the electronic equipment for use by a passenger;
providing a controller operably coupled to the electronic equipment; and
providing an interface unit associated with the passenger seat, the interface unit communicatively coupled to the controller, and the interface unit including a display;
displaying each of a standard operating mode of the electronic equipment and a power saving operating mode of the electronic equipment on the interface unit;
selecting, via the interface unit, the standard operating mode of the electronic equipment to operate the electronic equipment without power consumption restrictions; and
selecting, via the interface unit, the power saving operating mode of the electronic equipment to operate the electronic equipment with power consumption restrictions;
wherein:
the electronic equipment comprises a plurality of seat actuators configured to adjust at least one seat element of the passenger seat:
when the standard operating mode of the electronic equipment is selected, the controller is configured to activate the plurality of seat actuators simultaneously and/or at a first actuation speed; and
when the power saving operating mode of the electronic equipment is selected, the controller is configured to activate the plurality of seat actuators sequentially and/or at a second actuation speed slower than the first actuation speed.

10. The method according to claim 9 , wherein at a conclusion of a flight of the aircraft:
the controller is configured to determine a power usage of the electronic equipment operated in each of the standard operating mode and the power saving operating mode of the electronic equipment;
the controller is further configured to calculate a difference between the determined power usages and communicate at least one of the determined power usages and the calculated difference between the determined power usages to the interface unit; and
the interface unit is configured to display to the passenger, via the display, at least one of the determined power usages and the calculated difference between the power usages.
