Patent number: 12523181Abstract: A blocking device for preventing an inappropriate shut-off of an engine of an aircraft. The blocking device enables by default the actuation of the shut-off unit and receives information representative of an activated or inactivated state of a fuel shut-off lever, of a reduced or non-reduced speed state of a throttle lever, and a correct or incorrect operating state of the engine. The blocking device blocks the actuation of the shut-off unit when the throttle lever is in an inactivated state, when the engine is in a correct operating state, and when, in addition, the throttle lever is in a non-reduced speed state or the throttle lever is in a reduced speed state and, in addition, the opposite propulsion engine is in a failed state or in an incorrect operating state.Type: GrantFiled: January 26, 2024Date of Patent: January 13, 2026Assignee: Airbus Operations SASInventors: Thierry Immordino, Guillaume Alix, David Boyer, Gilian Antonio, Bilal Guenchi

Patent number: 12312842Abstract: A striker assembly for a vehicle. The striker of the striker assembly, when retained within the associated latch mechanism, is configured to collapse towards the exterior surface of the associated hood, tailgate, or other door such that the exterior surface of the hood, tailgate, or other door is allowed to deflect inwards without the striker significantly contacting the exterior surface and becoming a point of contact for an impacting object causing the inwards deflection of the exterior surface. The striker assembly utilizes a reinforcement plate with a pair of deflection tabs or the like to enable this functionality, the striker contacting the pair of deflection tabs and being allowed to translate through the associated attachment plate of the striker assembly when hood impact occurs.Type: GrantFiled: December 28, 2022Date of Patent: May 27, 2025Assignee: Rivian IP Holdings, LLCInventors: David Boyer, Shubham Kulkarni, Revathi Krishnamoorthy

Publication number: 20230313573Abstract: Disclosed embodiments include apparatuses, vehicles, and methods for managing operation of a latch securing a vehicle compartment hatch. In an illustrative embodiment, an apparatus includes a primary latch that defines a slot configured to receive a striker extending from the hatch and is rotatable between a locked position where the slot is oriented to hold the striker to retain the hatch in a closed position and an unlocked position in which the slot is oriented to enable the striker to be withdrawn from the slot to permit opening of the hatch; and a secondary latch mechanism configured to be moved between: a first configuration configured to maintain the primary latch in the closed position; a second configuration configured to enable the striker to move within the slot to permit partial opening of the hatch; and a third configuration configured to enable the primary latch to rotate to the unlocked position.Type: ApplicationFiled: March 31, 2022Publication date: October 5, 2023Inventors: Marcus Merideth, Thomas Young, Kosta Papanikolaou, David Boyer, Joshua Rogers

Publication number: 20230159180Abstract: A method for managing power drawn from power units of propulsion units of an aircraft, wherein the method includes a step of increasing the amount of power drawn from a second power unit that is time shifted, with respect to a step of increasing the amount of power drawn from a first power unit, for a duration that at least allows the operational state or the non-operational state of the first power unit to be determined. This solution allows simultaneous switching to the non-operational state of the two power units to be avoided.Type: ApplicationFiled: November 21, 2022Publication date: May 25, 2023Inventors: Patrick Zaccaria, Pierre Daste, Paul-Emile Roux, Didier Poirier, Guillaume Alix, David Boyer, Lucie Coue, Souhaib Boukayoua

Publication number: 20220372799Abstract: Various disclosed embodiments include illustrative devices, systems, and methods. In an illustrative embodiment, a device includes a latch motor configured to generate a power value, a position sensor configured to generate a striker pin position signal, a processor configured to communicate with the latch motor and the position sensor, and a memory configured to store computer-executable instructions. The computer-executable instructions are configured to cause the processor to determine the striker pin position in response to the generated striker pin position signal, detect an obstruction in response to the striker pin position and the power value, and perform an anti-pinch function in response to the detected obstruction.Type: ApplicationFiled: May 20, 2021Publication date: November 24, 2022Inventors: David Boyer, Marcus Merideth

Patent number: 11486318Abstract: To control an engine shutdown in an aircraft, a control system includes a fuel supply shut-off member, a control member with a set of switches, a first switch on an electrical power supply link of the fuel supply shut-off member and second switches connected to avionics of the aircraft, the set of switches switching position on an engine shutdown command. An engine shutdown confirmation unit includes a third switch on the electrical power supply link, the third switch in open position by default. The engine shutdown confirmation unit includes electronic circuitry configured to switch the third switch over to closed position when a predefined quantity Q of switches of the control member switches position within a sliding window of predefined duration and, otherwise, keeps the third switch in open position. Thus, it is ensured that the engine shutdown is intentional.Type: GrantFiled: May 11, 2021Date of Patent: November 1, 2022Assignee: Airbus Operations (S.A.S.)Inventors: Patrick Zaccaria, David Boyer

Publication number: 20220298971Abstract: A method for protecting, on spin-up, an aircraft engine including a power supply source, an engine with a rotor and associated with a starter system to, when supplied with power, produce a mechanical force to spin the rotor. The method includes an acquisition step performed continuously, wherein the engine control avionics acquire rotational speed of the rotor, a comparison step wherein the engine control avionics continuously compare acquired rotational speed against a predetermined rotational speed, and a checking step wherein the engine control avionics check that rotation of the rotor corresponds to deliberate pilot action, and if so, the engine control avionics authorize supply of power to the starter system, and, if not, in a deactivation step, the engine control avionics disconnect the engine starter system from its power supply source in order to stop the rotation of the rotor.Type: ApplicationFiled: March 16, 2022Publication date: September 22, 2022Inventors: Gilian Antonio, David Boyer
