Abstract: Methods and systems are provided for providing compression release during a stop/start event in an engine. In one example, a method includes: responsive to a request for a stop/start event in an engine with a continuously variable valve lift (CVVL) system including a compression release hydraulic valve actuator coupled to a valve of a first cylinder, determining a desired stop position of the engine; and prior to restarting the engine during the stop/start event, adjusting the compression release hydraulic valve actuator to open the valve during a compression stroke of the first cylinder. In this way, an amount of torque used to restart the engine may be reduced.

Abstract: A radial head assembly is provided that includes a stem, a collar, a locking ring, and an articular member. The stem has a convex articular head on one end thereof. The locking ring has a ring wall, which has a ring opening. The ring wall has an angular outer surface and a slot configured to permit the ring wall to radially expand. The angular outer surface engages an angular portion of an interior surface of the collar. The articular member and the locking ring define an articular space within the collar. The articular space is configured to receive the convex articular head.

Abstract: A stowable user interface system includes an armrest. The stowable user interface system includes a steering wheel support arm supported by the armrest and movable between an extended position outside the armrest and a retracted position inside the armrest. The stowable user interface system permits an operator of a vehicle to control a steering system of the vehicle when the steering wheel support arm in the extended position. The stowable user interface system stows the steering wheel support arm in the retracted position.

Abstract: A system that includes a vehicle fuel-receiver comprising a port located on a vehicle surface; and an onboard computer programmed to: send a fuel delivery request to an unmanned aerial vehicle (UAV); actuate the port to permit the UAV to deliver fuel; and instruct a communication module to transmit a beacon signal to the UAV.

Abstract: A vehicle charging system includes a vehicle charge port having a first connector with one or more first magnets and a plurality of first terminals arranged in a first array. A charge station for the vehicle includes a support and a second connector attached to the support by an articulating mechanism that permits movement of the second connector relative to the support. The second connector has one or more second magnets and a plurality of second terminals arranged in a second array that matches the first array so that the first terminals are connectable to the second terminals when the first and second connectors aligned. The first and second magnets are arranged to move the second terminals, via the articulating mechanism, into alignment with first terminals when the first and second connectors are within a magnetic-coupling range.

Abstract: The invention relates to a composite sheet, and a ballistic resistant article, comprising unidirectionally aligned high performance polyethylene (HPPE) fibers and a polymeric resin, wherein said polymeric resin comprises a homopolymer or copolymer of ethylene and wherein said polymeric resin has a density as measured according to ISO1183 of between 930 and 980 kg/m3, and a peak melting temperature of from 115 to 140° C.; and said polymeric resin is present in an amount of from 5 to 25% by weight based on the total weight of the composite sheet. It further relates to a method for manufacturing a composite sheet comprising assembling HPPE fibers to a sheet, applying an aqueous suspension of a polymeric resin to the HPPE fibers, partially drying the aqueous suspension, optionally applying a temperature and/or a pressure treatment to the composite sheet.

Abstract: Methods and system for providing heat to a vehicle are presented. In one example, a refrigerant loop is operated to heat a passenger cabin via heat generated by a compressor and heat generated by a resistive heating element. The heat that is generated by the compressor and the heat that is generated by the resistive heating element is transferred to a refrigerant before it is transferred to the passenger cabin.

Abstract: Methods and systems are provided for restarting an engine following an engine idle-stop. In one example, a method may include upon receiving an engine restart request during an engine idle-stop, initiating combustion in a selected cylinder and based on a predicted time of attainment of peak pressure in the cylinder, activating a starter motor.

Abstract: Methods and systems are provided for operating a split exhaust engine system that provides blowthrough air and exhaust gas recirculation to an intake passage via a first exhaust manifold and exhaust gas to an exhaust passage via a second exhaust manifold. In one example, each of a first valve positioned in an exhaust gas recirculation (EGR) passage, the EGR passage coupled between the intake passage and the first exhaust manifold coupled to a first set of cylinder exhaust valves, and a second valve positioned in a flow passage coupled between the first exhaust manifold and the exhaust passage may be adjusted based on a measured pressure in the first exhaust manifold.

In one example, the ported scavenge manifold includes a first scavenge manifold coupled to a plurality of exhaust runners and a second scavenge manifold coupled to the plurality of exhaust runners via ports. The location of the ports on the exhaust runners combined with adjustments to a bypass valve coupled between the first scavenge manifold and an exhaust passage and an EGR valve coupled between the second scavenge manifold and the intake passage enables exhaust gas to be preferentially flowed to the exhaust passage and blowthrough air to be preferentially flowed to the intake passage under select operating conditions.

Abstract: A method for starting an engine is disclosed. The method may adjust exhaust valve opening timing of one or more cylinders during a first cycle of an engine since a most recent engine stop to reduce engine cranking work. The method may adjust exhaust valve timing if the engine is directly started or started via an electric machine.
