Abstract: A method for previewing a seat vantage-point in virtual reality for a venue. The method includes retrieving a seating chart for a venue from a database, receiving a user seat location selection within the seating chart for the venue, generating seat vantage-point data to be rendered in virtual reality based on the user seat location selection for the venue, and transmitting the generated seat vantage-point data to a user device, to be rendered in virtual reality. The method further includes receiving a seat availability, within the seating chart for the venue, for an event. The method further includes receiving an updated user seat location selection, within the seating chart for the venue, and adjusting the generated seat vantage-point data to be rendered in virtual reality based on the received updated user seat location selection.

Abstract: Methods and systems are provided for learning fuel injector error for cylinder groups during a deceleration fuel shut-off (DFSO), where all cylinders of an engine are deactivated, sequentially firing each cylinder of a cylinder group, each cylinder fueled via consecutive first and second fuel pulses of differing fuel pulse width from an injector. Based on a lambda deviation between the first and second pulses, a fuel error for the injector and an air-fuel ratio imbalance for each cylinder is learned. Alternatively or additionally, a difference in crankshaft acceleration between the first and second pulses relative to the expected deviation may be used to learn torque error, and adjust fuel injector error and air-ratio imbalance for each cylinder.

Abstract: This disclosure describes an aerial vehicle, such as an unmanned aerial vehicle (“UAV”), which includes a plurality of maneuverability propulsion mechanisms that enable the aerial vehicle to move in any of the six degrees of freedom (surge, sway, heave, pitch, yaw, and roll). The aerial vehicle may also include a lifting propulsion mechanism that operates to generate a force sufficient to maintain the aerial vehicle at an altitude.

Abstract: Methods and systems are provided for adjusting vehicle grille shutters based on a direction of motion of the grille shutters. In one example, a method includes adjusting a motor coupled to the grille shutters based on the direction of motion of the grille shutters, a desired opening of the grille shutters, and vehicle speed. Further, the method may include determining the direction of motion of the grille shutters based on a desired motor position relative to an actual motor position.

Abstract: Methods and systems are providing for improving engine coolant level estimation to reduce engine overheating. The level of fluid in a coolant overflow reservoir is inferred based on the fluid level in a hollow vertical standpipe fluidically coupled to the reservoir at top and bottom locations, while the fluid level in the standpipe is estimated based on output from an ultrasonic signal transmitted by a sensor positioned in a recess at the bottom of the vertical standpipe. The sensor uses a combination of raw echo times and processed fluid level data to estimate the fluid level accurately and reliably.

Abstract: In an aspect, a wear plate for use with a conveyor system is provided. The wear plate has a plate mount, having a fastener retainer having a retention hole extending through the wear plate, and a retainer support being defined by at least one cut in the wear plate adjacent to and at least partially defining the fastener retainer, the retainer support connecting the fastener retainer to a main portion of the wear plate and enabling the fastener support to be depressed relative to a top surface of the wear plate.

Abstract: Methods and systems include determining a cylinder air-fuel ratio imbalance in a multi-cylinder engine. In one example, the method may include sequentially firing an engine cylinder to provide an expected air-fuel deviation and learning cylinder air-fuel ratio imbalance based on an error between an actual air-fuel ratio deviation from a maximum lean air-fuel ratio relative to an expected air-fuel deviation during a deceleration fuel shut-off event.

Abstract: Methods and systems are provided to determine air-fuel imbalance of cylinders in a variable displacement engine. In one example, the method may include during a cylinder deactivation event, sequentially deactivating each cylinder of a cylinder group including two or more cylinders and estimating a lambda deviation for each cylinder following the sequential deactivation of each cylinder of the cylinder group; and learning an air error for each cylinder based on the estimated lambda deviation.

Abstract: Methods and systems are provided for conducting tests for undesired evaporative emissions on a vehicle fuel system and evaporative emissions system. In one example, a method may include learning routes commonly traveled by the vehicle, including altitude changes and stop durations, and may further include diagnosing the fuel system and evaporative emissions system based on the learned altitude changes in one example, and may include diagnosing the fuel system and evaporative emissions system based on a learned stop duration in another example. By conducting tests for undesired evaporative emissions as a function of learned travel routes, completion rates for tests for undesired evaporative emissions tests may be increased, and the release of undesired evaporative emissions to atmosphere may be reduced.

Abstract: Methods and systems are provided for scheduling an alarm wake up to self-wake a control module of a vehicle while the vehicle is off to perform requesting features, including diagnostic and non-diagnostic afterrun tasks. In one example, a method may include, during a shutdown event of the control module, querying a plurality of requesting features for alarm wake up times, receiving a plurality of alarm wake up times from the plurality of requesting features, selecting one alarm wake up time from the plurality of alarm wake up times received, and setting a timer for the selected alarm wake up time. When the timer elapses at the selected alarm wake up time, the control module is woken and a request to run is sent to each of the plurality of requesting features.

Abstract: A method is provided, comprising terminating a pressure rise portion of an engine-off natural vacuum test based on an initial rate of change of a fuel system pressure upon sealing a fuel system; and initiating a vacuum portion of the engine-off natural vacuum test responsive to suspending the pressure rise portion. The initial rate of change may indicate a likelihood of the pressure rise portion reaching a pressure rise threshold. In this way, the vacuum portion of the test may be initiated earlier, increasing the likelihood of a conclusive result being obtained during a test time limit.
