An aircraft seat group is described. The aircraft seat group includes first and second aircraft seats. The seat group also includes a center console between the aircraft seats. The center console includes a microphone unit including an audio transducer. The audio transducer generates a voice recording of a passenger sitting on one of the seats in response to a signal, thereby reducing privacy concerns. The signal is received by one or more of a record button or a communication interface. The voice recording may thus provide one or more of passenger recommendation or flight recordings during emergency conditions. The microphone unit is embedded in one or more of an armrest or a seat back divider of the center console.

Innovative peripheral bar assembly for a transportation vehicle is provided. The assembly includes a front bar housing with a front segment and a rear segment, and a through slot aligned with a diffuser operationally coupled to a first surface of an I/O PCB having a plurality of light sources emitting light that is transmitted through the diffuser and the slot. The assembly further includes a rear bar housing having a front segment and a rear segment, the front segment of the rear bar housing coupled to the rear segment of the front bar housing. A top surface of the peripheral bar assembly is coupled to a bottom of a chassis of a display system having a display module. The assembly configured to provide accent lighting through the slot of the front bar housing.

Methods and systems are provided for assisting operation of a vehicle using speech recognition. One method involves analyzing a transcription of an audio communication with respect to the vehicle to characterize a nonstandard pattern within the transcription of the audio communication, obtaining a ground truth for the transcription of the audio communication, determining one or more performance metrics associated with the nonstandard pattern within the transcription based on a relationship between the transcription of the audio communication and the ground truth for the transcription, updating a speech recognition vocabulary for the vehicle to include the nonstandard pattern based at least in part on the one or more performance metrics and determining an updated speech recognition model for the vehicle using the updated speech recognition vocabulary and the audio communication.

An aircraft emergency control system comprises at least one sensor configured to output an electronic signal relating to detection of incapacitation of at least one aircraft crew member. A processor is configured to receive and process the electronic signal to determine whether emergency action is to be taken. A control unit is configured to communicate, in use, a control signal to an avionics system of the aircraft in relation to the emergency action if the processor determines that emergency action is to be taken.

An electronic display apparatus comprising a support frame, wherein mounted within the support frame there is an electronic display configured to display content based on image data, and a display driver circuit to receive the image data and to supply an image signal to the electronic display to cause the electronic display to display the content, the image signal based on the image data. Also mounted in the support frame is a connector cable connecting the display driver circuit and the electronic display for transmission of the image signal from the display driver circuit to the electronic display. The support frame is mountable to one or more surfaces so as to mount the electronic display to a first portion of the one or more surfaces and mount the display driver circuit to a second portion of the one or more surfaces that is away from the first portion, and the support frame maintains the electronic display in a spaced relationship from the display driver circuit.

This invention relates to a stair assembly to be arranged in a stairwell opening of an upper floor, comprising: —a girder assembly; —a plurality of steps mounted to the girder assembly; and —a guard structure, wherein the girder assembly is pivotably mountable to the upper floor to pivot about a pivot axis between an operational position, in which the girder assembly extends obliquely downwards, and a hidden position, in which the girder assembly extends horizontally, wherein the moveable guard structure is moveable between an operational position, in which the guard structure extends upwards, and a hidden position, in which the guard structure has moved downwards, and wherein the stair assembly is configured such that when the girder assembly and the guard structure are in their respective hidden positions a person is able to walk over the stair assembly as part of the upper floor.
