Abstract: A navigation control system includes an obstacle detector on a hull to detect a distance from a hull to an obstacle on a water surface and a position of the obstacle, a thruster on the hull to generate a propulsive force, a steering to steer the thruster to right and left sides of the hull, and a controller configured or programmed to perform a control to determine an obstacle avoidance route based on a route function including at least an indicator of a lateral acceleration that acts on the hull during steering of the thruster when the obstacle is detected by the obstacle detector.

Abstract: A marine propulsion system includes a controller configured or programmed to perform a marine vessel traveling direction control such that a traveling direction of a marine vessel is changed to a predetermined angle equal to or greater than a first angle with respect to a traveling direction of waves toward the marine vessel when the traveling direction of the marine vessel is less than the first angle with respect to the traveling direction of the waves toward the marine vessel.

Abstract: A marine vessel maneuvering system includes a controller configured or programmed to perform a water entry determination control to determine whether or not water behind a hull that rises above a water surface due to deceleration of the hull may enter the hull when the hull is decelerating.

Abstract: An engagement part fitted in an outer package of an ink cartridge is provided with: a fit-in rib which is provided at a circumferential edge on a rear side and which serves as a guide upon engagement with an opening of the outer package; an engagement rib provided upright at the circumferential edge of the engagement hole in the same direction as a direction of the fit-in rib; and a bonding region for bonding a communication tag that performs near field radio communication with a printer. A tag-removing hole which is formed in the bonding region and which is to be removed from a bonding surface side of the communication tag with a bar-like member inserted is formed in a formation region as the bonding region located in a first quadrant and a fourth quadrant in an orthogonal coordinate system.

Abstract: The present invention aims at estimating a residual life of a blasting vessel. For the estimation, a strain gauge 30 is attached to a blasting vessel 10. The strain gauge 30 measures high-frequency repetitive strain caused in the blasting chamber 10 in each explosion. Strain waveform data obtained with the strain gauge 30 is analyzed to calculate the cumulative degree of fatigue damage due to a high-frequency repetitive load applied to the blasting vessel 10 in each explosion. A residual life of the blasting vessel 10 is estimated on the basis of a cumulative value of the cumulative degrees of fatigue damage.

Abstract: In a license plate information reader device (A) for motor vehicles, a CCD camera (1) is provided to produce video image data (11) involving a license plate obtained by photographing a front and rear portion of a motor vehicle. An A/D converter (3) produces a digital multivalue image data (31) by A/D converting the video image data (11). A license plate extracting device (4) is provided to produce a digital multivalue image data (41) corresponding to an area in which the license plate occupies. A literal region extracting device (5) extracts a literal positional region of a letter sequence of the license plate based on the image obtained from the license plate extracting device (4). A literal recognition device (6) is provided to recognize a letter from a literal image (571) of the literal positional region obtained from the literal region extracting device (5).

Abstract: In a fingerprint scanning device for use in identification, a fingerprint image input device is provided to photoelectronically input a specified fingerprint of an entrant. A monochrome image data of the ridge pattern of the entrant fingerprint is stored as fingerprint image data. A feature extraction device has a calculator which treats the ridge pattern image with one-dimensional group-delay spectrum transform in X- and Y-directions. The feature extraction device has the characteristic of isolating and emphasizing peaks of the individual frequency spectra in the form of differential with respect to a phase component frequency in Fourier transform analysis, and determining group-delay spectra in X- and Y-direction respectively as fingerprint feature portions.

Abstract: An electro-optical range finder using three modulation frequencies for providing light beams to be projected. The device is characterized by the fact that the highest frequency is not an approximation to the other two frequencies but the other two frequencies are approximation to each other.
