TL;DR: In this article, the authors used the theory of optimal control to find the best trajectories for the capture maneuver of an interplanetary probe, which employs electric propulsion, and optimized the thrust magnitude and direction to exploit the spacecraft continuous steering capabilities.
Abstract: The theory of optimal control is used to find the best trajectories for the capture maneuver of an interplanetary probe, which employs electric propulsion. The thrust magnitude and direction are optimized to exploit the spacecraft continuous steering capabilities and maximize the spacecraft final mass. Strategies, which involve propelled and coast arcs, are analyzed. The influence on the optimal trajectories of some parameters, such as the thrust, the specific impulse, and the initial velocity, is also discussed

TL;DR: A watercraft includes an improved engine control system that enhances the responsiveness of the watercraft and eases watercraft operation as mentioned in this paper, such as a jet propulsion unit, and an engine that powers the propulsion device.
Abstract: A watercraft includes an improved engine control system that enhances the responsiveness of the watercraft and eases watercraft operation. The watercraft includes a propulsion device, such as a jet propulsion unit, and an engine that powers the propulsion device. The engine control system is configured to maintain or increase engine speed under certain operating conditions.

TL;DR: The Self-Identifying Power Source for Use In Recharging Vehicles Equipped With Electrically Powered Propulsion Systems (SPSES) as discussed by the authors provides a unique identification of an outlet (or electric meter) to a vehicle which is connected to the outlet, to enable the vehicle to report the vehicle's energy consumption to the utility company.
Abstract: The Self-Identifying Power Source For Use In Recharging Vehicles Equipped With Electrically Powered Propulsion Systems provides a unique identification of an outlet (or electric meter) to a vehicle which is connected to the outlet (or electric meter) to enable the vehicle to report the vehicle's energy consumption to the utility company to enable the utility company to bill the vehicle owner and credit the outlet owner for the power consumed by the recharging of the vehicular battery banks.
