  • Patent number: 11586205
    Abstract: A marine autopilot system is disclosed. While in autopilot mode, the marine vessel's autopilot system autonomously steers the marine vessel's rudder. Steering input provided using the helm typically results in counter-steering to the autopilot. If the autopilot is following a current heading or course (route), the autopilot may continue its efforts to remain on the heading or course in response to the deviation caused by steering input to the helm. The disclosed autopilot system improves this problem by including one or more sensors that measure helm movement and wirelessly transmit helm movement data to one or more components of the marine vessel's electronic network. If the operator of the marine vessel manually steers the helm to deviate from a current heading or course, helm movement exceeding a predetermined autopilot disengagement threshold may cause the autopilot control to temporarily disengage, allowing a user to manually steer the marine vessel.

  • Patent number: 11477756
    Abstract: A system and a method are disclosed for enabling assignment of a responder unit to a user on a water vessel. The rescue system transmits a Short Message Service (SMS) message to a user device on the water vessel, the SMS message comprising a selectable option that, when selected, causes a location of the user device to be shared. Based on a selection by a user of the user device of the selectable option, the system receives a plurality of location coordinates from the user device at a plurality of respective times, each respective location coordinate describing a respective location of the user device at its respective time. The system selects a responder unit to assign to the user based on the plurality of location coordinates and a location of each of a plurality of candidate responder units. The system transmits location information to a responder device of the selected responder unit, the location information based on the plurality of location coordinates.

  • Patent number: 11448773
    Abstract: A system and a method are disclosed for enabling seamlessly tracking a location of a water vessel by supplementing satellite data with mobile data location based on proximity of a water vessel to shore. The system receives a Global Positioning System (GPS) location of the water vessel, the GPS location of the water vessel based on using the satellite data of the water vessel. The system determines that the GPS location is within a threshold distance of a boundary. Responsive to determining that the GPS location is within the threshold distance of the boundary, the system initiates monitoring for a mobile signal emanating from a trajectory path of the water vessel. The system detects, during the monitoring, the mobile signal, the tracking the location of the water vessel based on mobile data of the mobile signal. The system provides the tracked location to a monitoring device.

  • Patent number: 11443637
    Abstract: A proximity sensor system on a marine vessel includes one or more proximity sensors, each at a sensor location on the marine vessel and configured to measure proximity of objects and generate proximity measurements. A processor is configured to store a two-dimensional vessel outline of the marine vessel with respect to a point of navigation for the marine vessel, receive the proximity measurements measured by one or more proximity sensors on the marine vessel, and identify four linearly-closest proximity measurements to the two-dimensional vessel outline, including one closest proximity measurement in each of a positive X direction, a negative X direction, a positive Y direction, and a negative Y direction. The processor then generates a most important object (MIO) dataset identifying the four linearly-closest proximity measurements.

  • Patent number: 11383814
    Abstract: A sensor that detects a shape of a surrounding environment of a boat and a positional relationship between the surrounding environment and the boat body outputs environment information indicating the shape of the surrounding environment and the positional relationship. A display displays an environment map indicating the surrounding environment. An input accepts an input of a shore arrival target position of the boat body on the environment map and outputs target position information indicating the shore arrival target position. A controller receives the environment information and the target position information, determines a possible shore arrival space of the boat body in the surrounding environment based on the environment information, and corrects the shore arrival target position based on the possible shore arrival space. The controller generates an instruction signal to control a propulsion device so as to cause the boat body to arrive at the shore at the corrected shore arrival target position.

  • Patent number: 11366474
    Abstract: A zone in which a vessel is movable is expanded in a transverse moving mode using a joystick. When a tilt direction of a joystick is within a second range closer to a back-and-forth direction than a first range, a controller sets a steering angle of a right propulsion device and a left propulsion device such that the right and left propulsion devices are oriented bilaterally opposite to each other such that each is slanted at a predetermined angle with respect to the back-and-forth direction. The controller sets both the right and left propulsion devices to either a forward moving state or a rearward moving state. The controller controls a propulsive force of the right propulsion device and the left propulsion device such that a net force of the propulsive forces of the right and left propulsion devices is oriented in a direction corresponding to the tilt direction of the joystick.
