Abstract: A disturbance estimation apparatus including a navigation data receiver, a thrust data receiver, and processing circuitry is provided. The navigation data receiver acquires navigation data including an actual position and time of the ship on a water surface. The thrust data receiver receives thrust data indicating a magnitude and a direction of a thrust force of the ship. The processing circuitry estimates a predicted position of the ship at a future point in time and a predicted arrival time of the ship to reach the predicted position by inputting the navigation data and the thrust data into a first trained model, and determines disturbance data including a drift direction and drift speed of the ship drifted by an external force based on a difference between the predicted position estimated by the first trained model and the actual position of the ship at the predicted arrival time.

Abstract: A ship control device is provided with an input unit capable of acquiring operation inputs from each of a first operator used in a low-speed navigation control mode and a second operator used in a high speed navigation control mode, and a control unit for determining a target direction and a throttle opening in the direction control at the time of navigation based on the operation inputs acquired in the input unit. The low-speed navigation control mode has a manual operation control mode by the operation of the first operator and an automatic navigation control mode for holding a direction or a throttle opening using the target direction. The control unit is provided with a setting unit for setting the target direction and the throttle opening used for automatic navigation based on the operation input to the first operator in the automatic navigation control mode.

Abstract: A ship speed control system includes: a ship speed deviation calculation module which calculates a ship speed deviation based on the difference between an actual ship speed and a ship speed target value; and an input gain adjustment module which adjusts a gain input to a throttle control function to a first gain value when the ship speed deviation is not less than a first threshold value, and adjusts the input gain to a second gain value which is larger than the first gain value and smaller than the initial gain value when the ship speed deviation is not less than the first threshold value and not less than the second threshold value.

Abstract: A slot array antenna includes a waveguide and a horn. The waveguide has a first surface including multiple slots arranged along a longitudinal direction of the first surface to radiate radio waves. The width of the first surface in the lateral direction is greater than half of a wavelength of the radio waves. The horn, fixedly attached to the waveguide, enlarges towards a radiation direction of the radio waves. The horn has upper and lower portions bent inwards twice with respect to a lateral direction of the first surface to form first and second narrow openings. An opening width of the first narrow opening is less than the width of the first surface. An opening width of the second narrow opening is less than or equal to two fifth of the wavelength. Thus, a side lobe generated due to horizontal polarization of the radio waves is suppressed.

Abstract: The present disclosure is to provide a measurement chip, a measuring device, and a measuring method which can accurately estimate an analyte concentration with a simple configuration. A measurement chip may include a propagation layer, an introductory part, a drawn-out part and a reaction part. Through the propagation layer, light may propagate. The introductory part may introduce the light into the propagation layer. The drawn-out part may draw the light from the propagation layer. The reaction part may have, in a surface of the propagation layer where a reactant that reacts to a substance to be detected is formed, an area where a content of the reactant changes monotonously in a perpendicular direction perpendicular to a propagating direction of the light, over a given length in the propagating direction.

Abstract: The present disclosure provides an image generating device capable of making a situation around a ship comprehensive. The image generating device includes processing circuitry. The processing circuitry acquires ship data indicative of a two-dimensional position of a ship on a water surface. The processing circuitry places a three-dimensional ship object indicative of the ship, at a position of a virtual water surface in a virtual three-dimensional space corresponding to a two-dimensional position of the ship. The processing circuitry sets a virtual camera in a bird's-eye view mode in which the three-dimensional ship object is looked down obliquely from a position higher than the three-dimensional ship object. The processing circuitry generates a three-dimensional image in which a sight within a field of view of the virtual camera including the three-dimensional ship object is drawn. The processing circuitry generates an image for indication including the three-dimensional image.
