An autonomous impact detection device includes at least one impact detector; at least one wireless transmission device configured to transmit the information collected by the impact detector; at least one energy storage device configured to supply the impact detector and the wireless transmission device with energy; at least one Seebeck module configured to supply the storage device with energy when a temperature gradient is applied thereto; the wireless transmission device being configured to supply the storage device with energy when the temperature gradient to which the Seebeck module is exposed is not sufficient.

Device for detecting impacts, associated detection system and aircraft equipped with such a system

The present invention relates to a method for verifying the presence of equipment (E) on board an aircraft, the method comprising the following steps:&#x2014;during a flight of the aircraft, implementing () radio communication tests by means of a device () on board the aircraft so as to determine an in-flight list of equipment consisting of any equipment having a quality of radio link with the radio communication device () higher than a first predetermined quality threshold;&#x2014;after the flight, implementing () radio communication tests by means of the device () so as to determine a post-flight list of equipment consisting of any equipment having a quality of radio link with the radio communication device () higher than a second predetermined threshold after the flight;&#x2014;generating () an alert when an item of equipment is present on the in-flight list and absent from the post-flight list.

Method for verifying the presence of equipment on board an aircraft, and associated device

A method of detecting degradation of a real tire of a wheel includes the steps of: acquiring at least one first three-dimensional object representative of the shape of the real tire by using an electronic appliance including at least one three-dimensional sensor, the first three-dimensional object being made up of a set of capture points; determining the position of the center point of the real tire from the set of capture points; registering the first three-dimensional object to obtain a second three-dimensional object; transforming the second three-dimensional object in order to obtain one or more two-dimensional objects; and analyzing the two-dimensional object(s) in order to detect degradation of the real tire.

A monitoring system including pieces of measuring equipment and an LPWAN reception terminal. Each piece of measuring equipment has a sensor arranged to measure a parameter of the aircraft, an LPWAN antenna and an LPWAN transmitter, an independent power source that powers the piece of measuring equipment, a main cut-off member connected between the independent power source and the LPWAN transmitter, and a main control component arranged to monitor operating parameters of the LPWAN transmitter and to open and close the main cut-off member selectively as a function of the operating parameters.

Aircraft monitoring system

A device intended to be installed in an aircraft, the device being adapted for functioning in a first so-called 'on the ground' operating mode or a second so-called 'in flight' operating mode, the device includes a radio module compliant with a low power wide area network standard adapted for sending messages comprising data issuing from a sensor and supplied by an energy storage element, the device being adapted for: (1) in the first operating mode: before the sending of each message, charging the energy storage element with a predefined energy, and (2) in the second operating mode: for each message to be sent, choosing a transmission power, determining, according to this transmission power, an energy necessary for the sending of the message by the radio module, and before the sending of the message, charging the energy storage element with the necessary energy determined.

Connected measuring device for an aircraft

A method for the management and maintenance of an aircraft including a zone with a high degree of security, a man-machine interface of the aircraft being included in the zone with a high degree of security and necessary for a maintenance operation to be performed by a maintenance operator on a device of the aircraft to be maintained placed outside the zone with a high degree of security. The method includes: connection of a first device to the high-security zone; connection of a second device to a third device; reception of the first device by the second device of the man-machine interface of the aircraft and transfer of information for display of the man-machine interface of the aircraft to the third device; and connection of the second device to a server by means of the telecommunication network in order to obtain information from the server intended for the third device.

A wheel comprising a rim carrying a tire that co-operates with the rim to define an inside volume, the wheel comprising a pressure measurement device comprising an electronic control circuit that is connected to a pressure sensor, to an absence-of-movement sensor for sensing that the wheel is not moving and to an electronic circuit for wireless communication, the pressure measurement device being arranged to cause pressure to be measured while the wheel is detected as not moving. A pressure measurement device and an associated measurement method.

Standalone on-board pressure measurement device, and pressure measurement method

A method of monitoring the opening of a container, the method comprising the steps of:

Method for monitoring the opening of a container

A method for collecting operational data from an aircraft having a display screen for operational data. The method includes using a mobile terminal equipped with at least one optical sensor, images of the display screen are acquired in such a way that at least some of the acquired images represent operational data displayed on the display screen; using an optical character recognition (OCR) module associated with said mobile terminal, character strings each representative of one piece of said operational data displayed on the display screen are identified in the acquired images; and using a report generation module and said identified character strings, an electronic report is generated containing at least some of said operational data of the aircraft.
