Abstract:
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.
Abstract:
Disclosed are watercrafts with rotatable air propulsion steering units and retractable measurement instruments. The watercraft can include a substantially flat bottom, a top deck, a rotatable air propulsion steering unit configured to propel the watercraft and to rotate in order to steer the watercraft when the watercraft is submerged in a liquid body without requiring a submerged rudder steering system under the substantially flat bottom. The watercraft can also include a retractable measurement deck configured to alternatively raise measurement instruments above the liquid body and lower into the liquid body.
Abstract:
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.
Abstract:
A watercraft includes a plurality of devices, a central controller, and a display device. The central controller is programmed to execute centralized control of the devices. The display device includes a touch panel function. The display device is configured to communicate with the central controller, and to display information regarding watercraft in a Graphical User Interface (GUI) format.
Abstract:
A wave-powered water vehicle includes a surface float, a submerged swimmer, and a tether which connects the float and the swimmer, so that the swimmer moves up and down as a result of wave motion. The swimmer includes one or more fins which interact with the water as the swimmer moves up and down, and generate forces which propel the vehicle forward. The vehicle, which need not be manned, can carry communication and control equipment so that it can follow a course directed by signals sent to it, and so that it can record or transmit data from sensors on the vehicle.
Abstract:
A method for controlling movement of drive units on a marine vessel includes receiving an operator request for a desired steering angle. A first drive unit's steering angle is set equal to the desired steering angle. A midpoint of a wetted surface area of the vessel hull is determined and a pivot line extending laterally through the midpoint and perpendicular to the hull's longitudinal axis is defined. A first intersection point of the pivot line and a line extending horizontally through the first drive unit's steering axis and parallel to the longitudinal axis and a second intersection point of the pivot line and a line representing perpendicular application of hydrodynamic force on the first drive unit are determined. A second drive unit's steering angle is set such that a line representing perpendicular application of hydrodynamic force on the second drive unit intersects the pivot line at the second intersection point.
Abstract:
A remote steering system is provided. The remote steering system includes a steering device configured to control a traveling direction of a ship by at least adjusting an angle of a rudder, and a remote control device configured to remotely control the steering device. The remote control device includes an azimuth sensor configured to detect an oriented azimuth of the remote control device, and a controller communication unit configured to transmit, to the steering device, at least one of the oriented azimuth detected by the azimuth sensor and a change amount of the oriented azimuth. The steering device receives the at least one of the oriented azimuth and the change amount from the remote control device, and controls the traveling direction of the ship based on the at least one of the oriented azimuth and the change amount.
Abstract:
A system that controls the speed of a marine vessel includes first and second propulsion devices that produce first and second thrusts to propel the marine vessel. A control circuit controls orientation of the first and second propulsion devices about respective steering axes to control directions of the first and second thrusts. A first user input device is moveable between a neutral position and a non-neutral detent position. When a second user input device is actuated while the first user input device is in the detent position, the control circuit does one or more of the following so as to control the speed of the marine vessel: varies a speed of a first engine of the first propulsion device and a speed of a second engine of the second propulsion device; and varies one or more alternative operating conditions of the first and second propulsion devices.
Abstract:
A remote operating device for remotely operating a floating device having a water jet drive includes a first operating unit for receiving control data as well as an actuator for controlling and/or adjusting the power of the water jet drive. The actuator may include a first actuating element for mechanically controlling the power of the water jet drive of the floating device. Alternatively, the actuator may include a first electronic module for feeding a voltage signal into engine electronics of the floating device, for controlling the power of the water jet drive.
Abstract:
A remote controlled motorized buoy is provided for rescuing people in the water. The buoy may be controlled by a person with a remote control to navigate to the person in need. The buoy may have flotation mechanisms to keep the buoy right side up in rough water conditions and includes visual indicators to help the user keep track of the buoys location, such as a flag and beacon. When the buoy is near the swimmer, the swimmer may grab the buoy and the buoy may be remotely navigated to bring the swimmer to a safe location.
