A removable barrier and an aircraft including such a removable barrier. The barrier including a panel configured to block at least partly an opening delimited by a frame, a plurality of straps each connected to the panel and each having first and second ends, for each strap, a first connection configured to connect the first end of the strap and a first edge of the frame at least temporarily, a second connection configured to connect the second end of the strap and a second edge of the frame at least temporarily, at least one folded overlength at the level of at least one of the first and second ends of the strap, at least one breakable connection keeping the overlength folded.

A lighting device includes: a communication unit that communicates with a vehicle which drives autonomously; a diagnostic unit that performs, via the communication unit, diagnosis as to whether the vehicle is being hacked; and a light emitter that emits illumination light onto at least one of the vehicle, a road on which the vehicle travels, or a parking space in which the vehicle parks.

A denoising apparatus, including a Micro-Electro-Mechanical System, MEMS, sensor circuit, which is configured to generate a measurement signal in response to a physical quantity. The measurement signal includes a useful signal component indicative of the physical quantity and an attack signal component due to an attack on the MEMS sensor circuit. The denoising apparatus further includes a machine learning circuitry, which is configured to estimate the useful signal component based on the measurement signal. The machine learning circuitry is trained based on training signals comprising known useful signal components and known attack signal components.

A system is described. The system may detect whether a user within a flight deck is authorized to control the aircraft. The user may receive differing levels of authority to control the aircraft depending on whether the user is authorized or unauthorized. The system may also control the aircraft depending on the various phases of the aircraft, including in flight and on the ground. The system may also be used to unlock the controls for the aircraft. The system may unlock the control using biometric information or nonbiometric information. The system may include a camera which is added to a flight deck. The camera may capture images of users within the flight deck. Faces within the images may be detected and compared against authorized users for locking or unlocking the aircraft controls.

A cockpit access security system controls changes to a record of personnel authorized to access the cockpit by reference to the state of the aircraft as determined by a plurality of on-board sensors indicating the state of particular aircraft subsystems.

A device for preventing access to an area of an aircraft includes a first vertical frame post designed for attachment to a structure of the aircraft, a second vertical frame post designed for attachment to a structure of the aircraft, a barrier element displaceably connected to the first frame post and including a latching element for detachable connection of the barrier element to the second frame post, and a delay unit including a spring-loaded damping cylinder displaceable into a damping position by a locking movement in opposition to a spring force. The delay unit is designed to release the latching element after a time delay.

A tamper detection system for a life vest storage container (10) on board a passenger aircraft (A), includes a receptacle (4) having an access opening with a closable lid (7); a first electrically conductive monitoring pad (1) formed on the closable lid (7); a second electrically conductive monitoring pad (2) formed on the receptacle (4); a non-conductive sealing member (3) including conductive patches of adhesive on the bottom side of two opposite edges of the sealing member and a conductive element leading between the two patches, the two patches applied to electrically conductive monitoring pads (1, 2); and a monitoring system (5) electrically coupled to the monitoring pads (1, 2) and configured to measure an electrical parameter associated with the electrically conductive path (C1, C2, CS) formed by the monitoring pads (1, 2) and the electrically conductive element within the sealing member (3).

A vehicle surface 30, preferably wherein the vehicle is an aircraft, is described. The vehicle surface 30 comprises thereon and/or therein a set of retroreflectors 300, including a first retroreflector 300A, configured to reflect, at least in part, incident hostile light towards a source thereof.

A method and system for protecting an aircraft against an incoherent command instruction. The system has a generation unit generating a command instruction transmitted to an evaluation unit that evaluates whether or not the command instruction is incoherent and generates and transmits a validation order if the command instruction is coherent or an arbitration request if not, the arbitration request being transmitted by an arbitration unit, where applicable, to an operator who sends a confirmation response or a cancellation response. The arbitration unit generates and transmits a validation order to an execution unit in the event of receiving a confirmation response and a cancellation order in the event of receiving a cancellation response, the system allowing the execution unit to execute only the command instructions evaluated and confirmed as not being incoherent.

Various systems and methods for disabling UAVs are presented. An interrogation system may transmit an identifier request message to a UAV. The interrogation system may receive, in response to the identifier request message, a response message that indicates a UAV identifier. The interrogation system may access one or more UAV identifier databases that relate UAV identifiers with airspace definitions. The interrogation system may retrieve from the one or more UAV identifier database systems an airspace definition corresponding to the UAV identifier. The interrogation system may determine that the UAV is to be disabled based on: a location of the UAV, a restricted airspace definition, and the airspace definition corresponding to the UAV identifier. The interrogation system may then transmit a disablement instruction message to the UAV based on the location of the UAV and the airspace definition corresponding to the UAV identifier.
