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.

This application describes clutch mechanisms for use in a steering control system, e.g., a steering control system used to steer a trolling motor for a boat. Such clutch mechanisms can reduce and avoid damage to the steering control system (e.g., a steering motor) when the system is subjected to unusually large impact loads (e.g., when the trolling motor or boat contacts an obstruction). The clutches described in this application can be used to decouple the steering control system from a steering shaft (or other drive mechanism) upon application of a large impact load, thus reducing damage to and increasing the lifespan of such system. In some cases, the clutch is a ball and spring mechanism. In other cases, the clutch is a slip tooth mechanism.

A visual direction guide for a fishing boat trolling motor to enable a fisherman or other operator positioned remotely in the boat from the trolling motor to visually determine the direction of propulsion of the trolling motor so the operator can steer the motor even when the view from the operator of the trolling motor is visually obstructed by another fisherman, chair, or other object. The visual direction guide has a support shaft, a visual indicator located at the top of the support shaft, and mounting apparatus to secure the support shaft to the trolling motor, so that the visual indicator can be seen by the operator above any visual obstruction to determine the direction of propulsion of the trolling motor to remotely steer the trolling motor. The visual indicator can include a vane, and can include lights. The support shaft can telescope, fold down, or be removed for storage.

The present disclosure provides an intelligent port control system and related systems and apparatuses, capable of achieving fully automated ship loading and unloading. 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.

The application relates to systems and techniques for remotely navigating a marine vessel. The systems can include a dynamic positioning system and/or a marine location management system for remotely navigating a marine vessel. The marine location management system can include a communication module for receiving a geographic location of the marine vessel and transmitting a navigation plan to a vessel control system. The marine location management system can also include a processor adapted to determine the geographical coordinates of the marine location and the marine vessel. In some cases, the marine vessel can include a thruster system adapted to receive the navigation plan and determine a set of thrust vectors based on the navigation plan.

A watertight, transom mounted, electric marine sterndrive propulsion drive unit mounted to an external surface of the transom of a marine vessel comprising an integrated electric motor with an output shaft, an intermediate drive shaft mechanically coupled to the electric motor output shaft, one or more propeller shafts mechanically coupled to the drive shaft, and one or more propellers mechanically coupled to the one or more propeller shafts.

A marine vessel maneuvering system includes a controller configured or programmed to control a steering speed to be a first steering speed when an operator is moved from a neutral position, and to control the steering speed to be a second steering speed that is lower than the first steering speed when the operator is returned to the neutral position.

A decoy system with a ballast that holds batteries to power the various elements of the decoy system including a Global Positioning System or location based receiver and circuitry that automatically controls the navigation of the decoy based on real-time location and desired/selected pattern information. The system can include a decoy with a propulsion system and steering system and an interface to a smart phone running a remote control app. The remote control app can be used to control the navigation of the decoy in view of the location information received from the GPS.

The invention relates to a craft in the form of a body to be sat or laid upon by a user and provided with power for use in a body of water. There is also provided a method for the use of the craft in game play and the use of the same in a manner which allows the power source for the drive to be managed. A system for transport, charging and/or communication with the craft from onshore is also provided, along with a system to allow the use of the craft within a specified area on the body of water to be maintained and controlled.
