Abstract: 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the hatch in a closed position and an unlocked position in which the slot is oriented to enable the striker to be withdrawn from the slot to permit opening of the hatch; and a secondary latch mechanism configured to be moved between: a first configuration configured to maintain the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.

Abstract: 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.

Abstract: This disclosure provides an ocular tissue depot of a selected complement factor D (CFD) inhibitor for the extended treatment of an ocular disorder mediated by complement factor D. In particular, the disclosure includes the creation of a drug depot within the choroid-retina pigmented epithelium (C-RPE) and/or the iris-ciliary body (I-CB) of the eye by means of the systemic (oral or parenteral) administration of the compound, where the compound accumulates in ocular tissue and is released over an extended period for the treatment of a posterior and/or anterior eye disorder.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An ambidextrous safety selector assembly for use with a rifle having a receiver with holes into which the assembly is inserted and that includes a main body with a user manipulated tab on the exterior of a rifle receiver and an elongated portion that extends into the receiver with a terminal channel defining three clocking faces and an intermediate hole that mate with protruding male faces with a terminal pin on a secondary body with a user manipulated tab on the exterior of a rifle receiver. The male faces of the secondary body are inserted and coupled into the terminal channel of the main body and clocked against the faces of the channel and the pin of the secondary body is inserted and coupled into the hole of the main body when the main body and secondary body are inserted into the receiver. The secondary body also has a foot protruding outwardly and extending into the receiver to retain the assembly in the receiver.

Abstract: Methods are disclosed that improve the location of a ground based Wi-Fi device using an airborne Wi-Fi station. One embodiments of the disclosure describes the periodic transmission of bursts of RTS packets in order to reduce interference to the responding CTS packets. Another embodiment of the disclosure describes the use of specific values used in the RTS Duration fields that enable the responding CTS packet to be identified and linked to the RTS packet to which it is responding. A further embodiment of the disclosure describes the use of a packet transmitted at the end of each burst that resets the NAV times for all ground networks.
