Abstract: A flock of vehicles can include a leader vehicle and at least one follower vehicle coupled to the leader vehicle. In some embodiments, the leader vehicle is a lawnmower. In some embodiments, the leader vehicle can include at least one sensor. In some embodiments, the flock of vehicles operate in an inverted V-shape configuration. In some embodiments, the leader vehicle and the follower vehicle are connected via a retractable cable. In some embodiments, a sensor of the leader vehicle can detect a unique feature on a follower vehicle. In some embodiments, a drone can be coupled to a leader vehicle. In some embodiments, an autonomous vehicle can utilize a safety wire.

Abstract: An autonomous guidance system can include an autonomous vehicle that utilizes both GNSS RTK data and SLAM data to navigate an outdoor environment. In some embodiments, the autonomous vehicle includes a GNSS antenna and at least one SLAM component. In some embodiments, the GNSS antenna is used in connection with a base station and at least one satellite. In some embodiments, the autonomous guidance system interacts with a mobile device associated with an operator.

Abstract: A method, system, and computer program product is provided, for example, for matching a geospatial message to one or more static objects on a link. The method may include identifying a location of an observation point for observing the one or more static objects from a vehicle on the link. The method may further include applying spatial filtering criteria to each of the one or more static objects based on an observable distance of each of the one or more static objects from the location of the observation point to filter the one or more static objects. The filtering of the one or more static objects may provide one or more filtered static objects. The method may further include calculating a heading of the vehicle and further using the heading of the vehicle for applying a heading filtering criteria to the one or more filtered static objects based on the heading of the vehicle and a pre-computed heading of each of the one or more filtered static objects to provide one or more candidate objects.

Abstract: In a compression ignition multi-fuel engine employing both port/intake manifold injection of fuel and in-cylinder injection of fuel, the recirculation of exhaust gas to the engine induction system is used to control the temperature and to set the reactivity of an air/fuel charge introduced to the engine for combustion. Fuel directly injected during compression of the charge controls ignition. A variable valve actuator for opening and closing an intake valve extends control over charge pressure and temperature to extend suppression of auto-ignition of the charge. Fuel injection strategy and variable valve actuation are subject to a control strategy to extend the benefits of premixed combustion.
