Methods and systems are provided for a transportation vehicle. A seat peripheral device includes a comparison component, a reference component, and a processor. The comparison component is configured to compare an input voltage and a reference voltage associated with a power supply component, where the input voltage is based on a supply voltage supplied to the seat peripheral device via a cable connected to the power supply component providing a DC voltage, and to output an output voltage based on whether the input voltage exceeds the reference voltage. The reference component is configured to generate the reference voltage based on the supply voltage when the DC voltage is at or above a threshold level. When the DC voltage drops below the threshold level during the power interruption, the reference component is configured to maintain the reference voltage at a same level as the reference voltage prior the power interruption.

A method comprises: detecting a triggering event related to operations of a feature implemented by a commercial transportation vehicle; receiving, in response to the detecting the triggering event, one or more requests associated with the feature, each of the one or more requests comprising a data structure containing information related to the operations of the feature associated with the request; querying at least one device or at least one database that supports the operations of the feature; aggregating one or more responses received from the at least one device or the at least one database in response to the querying; determining, based the aggregated one or more responses, a set of rules to configure the feature; and receiving the set of rules such that the feature operates based on the set of rules.

Systems and methods for performing wireless transceiver self-tests in an aircraft are described. An example method includes receiving, by an in-flight entertainment (IFE) system of a current seat on the aircraft, a message comprising an indication to perform a self-test for a wireless transceiver associated with the IFE system. A configuration in the message determines a first set of seats from which the current seat receives data and a second set of seats to which the current seat transmits data. The method then performs a first test for a receiver of the wireless transceiver and a second test for a transmitter of the wireless transceiver. Upon completion of the tests, the method transmits a report including an indication of whether the receiver is operational, an indication of whether the second test was completed, and a list of successful transmitters and failed transmitters associated with the first set of seats.

Innovative peripheral bar assembly for a transportation vehicle is provided. One method includes transmitting, by a processor of a seat device of an aircraft coupled to a peripheral bar assembly having a plurality of programmable light sources, one or more commands to the peripheral bar assembly to operate one or more of the light sources; and operating, by the peripheral bar assembly, the one or more light sources, in response to the one or more commands to indicate non-verbal communication associated with the aircraft.

Systems, devices, and methods for displaying celestial bodies in an aircraft are disclosed herein. In some embodiments, an IFEC system includes a database, a display device, and a processor operably coupled to the database and the display device. The processor can be configured to receive a first set of flight data from the aircraft, load a first GUI including one or more of the images and/or videos of celestial bodies arranged and/or modified based on the received first set of flight data, transmit the first GUI to the display device, receive a second set of flight data from the aircraft, load a second GUI based on the received second set of flight data, wherein the second GUI includes one or more of the images and/or videos of celestial bodies arranged and/or modified in a different manner than the first GUI, and transmit the second GUI to the display device.

Methods and systems are provided for a transportation vehicle. One method includes determining a visual impairment parameter indicating a degree of visual impairment of a passenger of a passenger seat associated with the seat device, determining a passenger location of the passenger and a location of a target, estimating an initial facing direction toward which the passenger faces, determining a position adjustment parameter indicating a position adjustment to be made by the passenger of the passenger seat to face the target, based on the passenger location, the location of the target, and the initial facing direction, and outputting a position adjustment instruction according to the position adjustment parameter, the position adjustment instruction including at least an audio instruction in response to the visual impairment parameter indicating visual impairment of the passenger.

A display in a commercial passenger vehicle can an option to be locked or unlock to enhance security. An example system for securing an in-vehicle entertainment (IVE) display in a commercial passenger vehicle comprises a mobile device and a computer. The mobile device comprises a first processor configured to secure a display located in the commercial passenger vehicle, where the first processor is configured to: obtain a payload; generate a first digitally signed payload as a first output of a first mathematical computation performed on the payload with a secret key; and send a first message comprising the first digitally signed payload and a lock command to instruct the display to lock the display. The computer is communicably coupled with the display and comprises a second processor configured to send a first instruction to cause the display to lock in response to a reception of the lock command.

A power supply system for use in an airplane is described. The power supply system includes N alternating current (AC) power outlets configured to provide AC power output at a passenger seat in an airplane, M direct current (DC) power outlets configured to provide DC power output at the passenger seat and a controller configured to control allocation of power from a power supply to the N AC power outlets and M DC power outlet according to a phase of a plurality of phases of operation of the power supply system, where N and M are positive integers.

A method for providing video programs for passengers on commercial passenger vehicles is provided. The method includes obtaining satellite beam coverage information indicative of beam coverages of one or more commercial passenger vehicles by one or more satellites; checking subscription information corresponding to a subset of commercial passenger vehicles in a beam coverage area of a particular satellite beam; generating, based on a result of the checking, a video program package including one or more video programs subscribed by the subset of commercial passenger vehicles; and transmitting the video program package to a satellite providing the particular satellite beam such that the one or more video programs of the video program package are transmitted through the particular satellite beam to the subset of commercial passenger vehicles.

A central computing platform provides users with control over multi-party information involving third-party services during different stages of a travel journey, or while users are provided with data connectivity via different networks or systems. The central computing platform provides a digital ledger on which the multi-party information is recorded. Recording of the multi-party information, as well as modification thereof, requires authentication of each party as well as input (e.g., approval) by the computing platform. The central computing platform can be communicatively coupled with local networks, such as cellular networks, as well as mobile platforms or in-vehicle connectivity systems to which user devices can be connected. As a result, the central computing platform is involved in generation, recording, modification, and fulfillment of multi-party arrangements between users and third-party services.
