Abstract: An example system includes a throttle control for managing power in a hybrid propulsion system that includes an electrical propulsion unit configured to operate using electrical energy sourced from an electrical energy storage system (ESS) and/or one or more electrical generators, the throttle control comprising: a control lever movable through a plurality of positions, the plurality of positions including: a regeneration position; an off position; a maximum electric only position; a maximum continuous dual source position; and a maximum non-continuous dual source position.

Abstract: A queuing management system for managing a queue of waiting vessels or persons having a pass-through point may include a camera system configured to generate one or more images of the queue and sequential images of the pass-through point. It may include an image processing system configured to calculate information indicative of the anticipated delay in the queue, the rate of passage through the pass-through point, the number of vessels or persons in the queue, the number of vessels or persons that have passed through the pass-through point, the type of vessel, and/or unusual movement of a vessel or person in the queue, all based on the images from the camera system. Related processes are also disclosed.
