Abstract: A method updates a digital system in a vehicle having an onboard client computer that communicates with a remote server, an onboard monitor-control unit operatively connected to the onboard client computer, and an electrical energy accumulator device for powering the onboard client computer and the onboard monitor-control unit. The method includes downloading a file from the remote server using the onboard client computer as long as the electrical energy accumulator device is capable of being recharged. Then at least part of the file that was downloaded is distributed to the onboard monitor-control unit using the onboard client computer. Then, all or a portion of the at least part of the file that was distributed is installed in the onboard monitor-control unit. Then the at least part of the file that was installed is activated after stopping the vehicle using the onboard monitor-control unit.

Abstract: A method for installing a computing component in an electronic device fitted in a vehicle, comprising the steps consisting of: receiving a device packet comprising a manifest including a hash value of the computing component; checking the integrity of the manifest; receiving the computing component; checking the correlation between the hash value of the computing component and the computing component received; installing the computing component only in the case of a positive check of the integrity of the manifest and a positive check of the correlation. An associated electronic device is also described.

Abstract: For dialogue from a first on-board bus in a vehicle, with a first computer connected to a second on-board bus, connected to the first bus by a second computer, with a main command being processed for the first computer: a third computer generates a command to write a description of the main command in a first dedicated zone of the second computer, then transmits the write command to the second computer; the second computer transmits, to the first computer, auxiliary command(s) to respond to the main command after receiving the write command; the third computer transmits a command to read the second dedicated zone, to the second computer such that the second computer transmits a response to the received read command; the third computer responds to the main command upon receipt of a response to the command to read a second zone of the second computer.

Abstract: An assembly comprising a vent tube intended to be mounted inside a turbine shaft of a turbomachine. The vent tube has a radially inner annular part from which at least one annular centering part extends radially outwards. The centering part has a groove and a sealing part of a sealing member is mounted in the groove. The sealing part is designed to come into sealing abutment against an inner surface of the turbine shaft. The sealing member has a protective part covering at least one area of the centering part situated upstream and/or downstream of the groove.
