The intelligent port control system includes: a scheduling center system configured to determine a ship loading plan based on ship information, container information, and shore crane apparatus information, and generate a ship berthing task, a ship loading task, and a container distribution task based on the ship loading plan, for transmitting to a ship control system of a target ship, a shore crane control system of a target shore crane apparatus, and a warehouse management system of a warehouse center, respectively.

Example steering control systems and methods for multiple devices are provided herein. A system includes a trolling motor assembly having a propulsion motor and a steering actuator and a sonar assembly comprising a transducer assembly and a directional actuator. The system further includes a user input assembly that is configured to detect user activity related to controlling operation of the trolling motor assembly and operation of the sonar assembly. The system further includes a processor that is configured to determine a direction of turn based on user activity, generate an electrical turning input signal indicating the direction of turn, and direct either one or both of the steering actuator and the directional actuator, via the turning input signal, to adjust a direction of either one or both of the propulsion motor and the transducer assembly accordingly.

A device for steering a trolling motor of a watercraft is provided. The device comprises a housing and a joystick attached to the housing, pivotably supported for movement from a neutral position in directions radial to an axis of the joystick. The movement from the neutral position generates a steering command for the trolling motor. The device has a transmitter within the housing and a processor communicatively coupled to the transmitter and the joystick. The device may further include a memory including a computer program code. The computer program code is configured when executed by the processor to receive movement data from the joystick, generate a steering command from the movement data, and transmit the steering command to the trolling motor. The steering command causes the trolling motor to rotate to aim in the steer direction to cause the watercraft to travel based on the joystick movement.

An amphibious pumping vehicle has a floatable vehicle body, a ground engaging propulsion structure, a fluid pump, a plurality of fluid nozzles comprising a first fluid nozzle connected by a fluid conduit to the fluid pump and at least one second fluid nozzle connected to the fluid conduit, a valve structure in the fluid conduit, the plurality of fluid nozzles and the valve structure co-operating to provide directional control and motive power for the vehicle when floating, and a power source configured to provide power to both the ground engaging propulsion structure and the fluid pump.

A system including a drone or unmanned vehicle configured to perform surveillance of a premises. The drone surveillance includes autonomous navigation and/or remote or optional piloting around the premises. The drone includes a controller coupled to a plurality of sensors configured to collect drone data and security data at the premises, wherein the controller is configured to generate control data for the drone and the premises using the drone data and the security data. A remote device coupled to the drone includes a user interface configured to present the drone data, the security data, and/or the control data.

A control system of a marine vessel includes a vessel control unit that controls the rotational position of at least one rotatable device on the marine vessel, and a head-mounted display in data communication with the vessel control unit. The head-mounted display has a sensor system that detects a facing direction and a display positioned in the operator's field of view that displays an indicator of the facing direction. The head-mounted display also includes an interface element that allows the operator to select the facing direction. The control system operates such that the vessel control unit adjusts the rotational position of the rotatable device based on the facing direction.

A multipurpose watercraft has a pair of catamaran pontoons supported by way of a transverse control bar at forward regions thereof. The watercraft may have an arched equipment rack framework extending above rearward regions of the pontoons. The watercraft also has a pair of electric motor thrusters located respectively beneath each pontoon and the control bar comprises a pair of controls operable by hand, each control operable to control a respective thruster forwards or backwards. Alternatively, the thrusters may be remotely controlled. This configuration allows an operator to be pulled behind the control bar horizontally between the pontoons, snorkellers to be pulled behind the watercraft for recreational sightseeing and/or for remote-control rescue operations.
