  • Patent number: 11365992
    Abstract: Vortex sensor amplitude information may be used to validate that a vortex signal being measured corresponds to an actual fluid flow and is not noise. The estimated amplitude of a sinusoidal vortex signal is used as a secondary means to determine the fluid flow based on vortex sensor characteristics. The original amplitude of the sinusoidal vortex signal is determined from a clipped voltage amplitude sinusoidal signal. The estimated velocity of the fluid in a pipe based on the original amplitude of the sinusoidal vortex signal is compared to the measured velocity of the fluid based on vortex velocity frequency. If the two determined velocities do not reasonably agree, the measured vortex signal is not a valid flow signal and adaptive filters are adjusted to reduce the effects of noise.

  • Patent number: 11027804
    Abstract: An underwater sailing body includes: a positioning device configured to detect positional information of a hull of the underwater sailing body; a posture detecting sensor configured to detect posture information of the hull; an actuator configured to apply thrust to the hull in a front-rear direction of the hull, a left-right direction of the hull, an upper-lower direction of the hull in water to change the position and posture of the hull; and a controller configured to control the actuator. In order to hold a hull at a target position when the hull receives an external force by disturbances, the hull keeps balance by using thrusters with respect to the external force acting on the hull. Specifically, the hull is held at the target position by controlling a thruster configured to generate thrust in a front-rear direction and a thruster configured to generate thrust in a left-right direction.

  • Patent number: 10926855
    Abstract: A method for controlling low-speed propulsion of a marine vessel powered by a marine propulsion system having a plurality of propulsion devices includes receiving a signal indicating a position of a manually operable input device movable to indicate desired vessel movement within three degrees of freedom, and associating the position of the manually operable input device with a desired inertial velocity of the marine vessel. A steering position command and an engine command are then determined for each of the plurality of propulsion devices based on the desired inertial velocity and the propulsion system is controlled accordingly. An actual velocity of the marine vessel is measured and a difference between the desired inertial velocity and the actual velocity is determined, where the difference is used as feedback in subsequent steering position command and engine command determinations.

  • Patent number: 10883830
    Abstract: A system can include an inertial measurement unit, a magnetometer configured to measure a magnetic field, and a processing system having an ORSE filter. The processing system can be configured to determine an estimated position based on a change in velocity or angular rate based on data received from the inertial measurement unit, determine a difference between the measured magnetic field from the magnetometer and the expected magnetic field measurement, and determine a state estimate using the ORSE filter by updating a time propagation of state and covariance with a measurement update of the state and covariance. The processing system can be configured to transform a change in velocity, a change in angulate rate, and the measured magnetic field to an Earth-centered inertial reference frame for the ORSE filter.

  • Patent number: 10875613
    Abstract: A motorized, floating device is associated with another aquatic device that carries a passenger or passengers (“associated aquatic device”). The invention comprises components such as one or more magnetic field emitters that deter aquatic animals from approaching the associated aquatic device without interfering with the operation of the associated aquatic device. The associated aquatic device may be a surfboard, a raft, a personal watercraft, or other similar small craft that floats in water. The invention may be used with larger boats and other watercraft. The motorized aquatic animal deterrent is tethered to the associated aquatic device to follow movement of the associated aquatic device but is spaced apart from the associated aquatic device.

The controller creates cruise trajectory information and stores the created cruise trajectory information in the storage based on the positional information of the watercraft in association with the type of the propulsion device on the watercraft. The controller determines a frequency at which cruise trajectories of the watercraft match the cruise trajectories based on the cruise trajectory information in the storage. The controller creates cruise route information in association with the type of the propulsion device on the watercraft.

The method includes measuring a current position and heading of the vessel; calculating a cross-track error based on the current position as compared to the desired track; and calculating a heading error based on the current heading as compared to the desired heading. The method includes generating corrective steering and thrust commands that are required to minimize the cross-track error and the heading error. The propulsion system propels the marine vessel according to the corrective steering and thrust commands, as appropriate.
