An aircraft air conditioning system comprises a plurality of temperature zones and at least one door. Comprises an air-conditioning unit configured to condition and provide air to at least one of the plurality of temperature zones, temperature zone sensors each associated with a temperature zone for measuring the temperature therein, and a control unit. The control unit receives information representing the closing state of a cabin door, and is coupled to the temperature zone sensors and configured to control the temperature of the conditioned air provided to at least one of the plurality of temperature zones in two operation modes. In a first mode, when doors are closed, the temperature control depends on the measured temperatures in the temperature zones. In the second mode, it depends on a set-temperature, independent of the measured temperature in a temperature zone affected by an open door.

A plurality of sensors are disposed in the interior space configured to sense a passenger condition.

A method of operation for a system incorporating a graphical user interface disposed in a bulkhead within a cabin of an aircraft. The method includes displaying a menu for at least one controllable parameter, receiving a selection of the controllable parameter, displaying at least one control for the selected controllable parameter, receiving a control input for the selected controllable parameter, and adjusting the selected controllable parameter consistent with the control input. The controllable parameter may be one from a plurality of controllable parameters selected from a group that includes cabin light intensity, cabin light color, temperature, and the degree of openness of at least one window shade. A system and an executable computer program product also are provided.

A system for controlling a cooling system comprises an operating state detection unit adapted to detect operating signals characteristic of the operating state of the cooling system and/or the operating state of a plurality of cooling energy consumers to be supplied with cooling energy by the cooling system and a database in which priority data dependent on the operating state and characteristic of the priority to be given to the cooling energy consumers in terms of the cooling energy to be supplied in various operating states of the cooling system and/or of the cooling energy consumers, is stored for a plurality of cooling energy consumers to be supplied with cooling energy by the cooling system.

Methods of determining an overall performance of air-conditioning system(s) are disclosed. The methods include transmitting data from a sensor operably coupled to at least one air-conditioning pack, comparing the transmitted data, determining an overall performance of the air-conditioning system(s) based on the comparing, and providing an indication of the determined overall performance of the air-conditioning system(s).

A processing system deployed in a carrier transport vehicle may establish a wireless communication session with a mobile device of a user, assign a zone of the carrier transport vehicle to the user, the zone including a plurality of network-connected devices, obtain a user profile from the mobile device of the user, determine at least one biometric sensor accessible via the mobile device of the user, obtain biometric data of the user from the at least one biometric sensor accessible via the mobile device of the user, determine a condition of the user based upon the biometric data, identify at least one adjustment to at least one of the plurality of network-connected devices in response to the condition of the user that is determined and the user profile, and apply the at least one adjustment to the at least one of the plurality of network-connected devices.

A passenger service system includes a seat, a first sensor associated with the seat that senses a position of the seat and generates a first signal, a second sensor associated with the seat that senses the presence of a passenger in the seat and generates a second signal, a first light source disposed at a predetermined location with respect to the seat, where the first light source generates light, a third sensor associated with the first light source that senses at least a position of at least one hand of the passenger and generate a third signal, and a controller that receives the first signal, a first light signal that controls at least one parameter associated with the light including at least one of an intensity, a color, a projected pattern, projected pattern location, or a width.

In a method for controlling an aircraft air conditioning system, a heating or cooling demand of an aircraft region to be air conditioned is determined. A volume flow of recirculation air discharged from the aircraft region to be air conditioned and a volume flow of compressed air into a mixing chamber of the aircraft air conditioning system is controlled such that the heating or cooling demand of the aircraft region to be air conditioned is met, while the volume flow of compressed air into the mixing chamber of the aircraft air conditioning system is minimized.

A vehicle passenger cabin control system that includes a cabin control panel having an interface that is operable to receive control commands. The cabin control panel is operable to control at least one passenger cabin system in response to a received control command. The cabin control system includes a first wireless data interface. The control system also includes a mobile device that includes a display screen, a user interface operable to receive control commands, and a second wireless data interface to send the control commands to the cabin control panel. Control commands received by the user interface of the mobile device are transmitted by the cabin control panel by the second wireless data interface and the first wireless data interface. The cabin control panel is operable to control at least one passenger cabin system in response to a received mobile control command.

An air conditioning system for an aircraft passenger compartment, the system including: an air supply circuit connecting at least one external air inlet to at least one air distribution outlet which opens into the compartment, an auxiliary power unit mounted in the supply circuit and configured to compress an air stream in the supply circuit, the supply circuit including a heating first branch that connects the auxiliary power unit to the air distribution outlet, and in which a heating mechanism is mounted, a cooling second branch that connects the auxiliary power unit to the air distribution outlet, and a switching mechanism configured to distribute the air stream between the heating first branch and the cooling second branch.
