Publication number: 20240124132Abstract: An uplock for the selective retention of a capture pin of a movable element includes a hook, a locking member, and a detector. The hook is movable between a release position and a retaining position for retaining the capture pin. The locking member moves between a locked position, and an unlocked position. The detector detects whether the hook is in the retaining position and the capture pin is in the hook. The detector includes a sensor movable relative to a target. The target or the sensor is carried by the locking member and the other by an indicator lever which is movable between a first position indicating absence of the capture pin in the hook and a second position indicating presence. The target and the sensor are only in the proximate position if the locking member is in the locked position and the indicator lever is in the second position.Type: ApplicationFiled: October 15, 2020Publication date: April 18, 2024Applicant: SAFRAN LANDING SYSTEMSInventors: Vincent PASCAL, Ludovic DUFAY

Publication number: 20240101249Abstract: An uplock for selectively retaining a capture pin of a movable element including a hook, a locking member, and a detector. The hook is movable between a release position and a retaining position. The locking member is movable between a locked position that immobilizes the hook and an unlocked position in which the hook is free. The detector detects whether the hook is in the retaining position and the capture pin is present in the hook. The detector includes a sensor associated with a single target which is movable between two positions The sensor emits a signal which is modified when the target passes from one of the positions to the other. The target is independently in kinematic interaction with the hook and the capture pin.Type: ApplicationFiled: October 15, 2020Publication date: March 28, 2024Applicant: SAFRAN LANDING SYSTEMSInventors: Vincent PASCAL, Ludovic DUFAY, Michel ARBENTZ

Publication number: 20230318589Abstract: A first input node receives a first input signal and a second input node receives a second input signal. The first and second input signals are in phase quadrature. An edge detector circuit senses the first input signal and produces a pulsed signal indicative of edges detected in the first input signal. A pulse skip and reset circuit senses the pulsed signal and the second input signal, and produces a reset signal indicative of pulses detected in the pulsed signal while the second input signal is de-asserted. A sampling circuit senses the second input signal and the reset signal, and produces an output signal that is deasserted in response to assertion of the second input signal and is asserted in response to a pulse being detected in the reset signal.Type: ApplicationFiled: March 28, 2023Publication date: October 5, 2023Applicants: STMicroelectronics S.r.l., STMicroelectronics (Rousset) SASInventors: Giulio ZOPPI, Vincent Pascal ONDE, Giuseppe ROMANO
