  • Patent number: 7756606
    Abstract: A method of controlling a redundant manipulator for assigning one or more redundant joints from a plurality of joints and obtaining the solution to an inverse kinematics problem at high-speed. The joints are arbitrarily classified into redundant joints and non-redundant joints, and an initial value is set for the joint angle of the classified redundant joint as a parameter. Then based on an evaluating function or a constraint condition defined by the joint angle of the redundant joint provided as a parameter and the joint angle of the non-redundant joint, which is determined by the inverse kinematics calculation according to the change of the parameter, an optimum solution of a set of joint angles is determined, and until the optimum solution covers the target range of the hand position, the procedure to determine the optimum solution is repeated with relaxing the constraint conditions.

  • Patent number: 7018456
    Abstract: A metal phthalocyanine compound that is useful as a black colorant suitable for use in an ink-jet recording ink, a water-based ink composition containing the metal phthalocyanine compound, and a product colored with the metal phthalocyanine compound. In particular, a metal phthalocyanine compound having, as substituents, both an acylamino group and a carboxyethylamino group on the phthalocyanine structure, or the salt thereof is used as a black colorant. Recorded images formed by the use of this colorant are excellent in light fastness and water fastness and exhibit absorption in infrared and visible regions, so that highly effective utilization can be found in printing of, for example, bar codes which are available in near-infrared ray reading.

  • Patent number: 6847326
    Abstract: The present invention provides a GPS device for measuring the wave height and current direction and speed, which is capable of accurately measuring the wave height (height of the waves) and current direction and speed (tidal current) in any point on the sea, ocean, lake, or marsh, and to a system using such a device. The GPS receiver 2 of the GPS device 1 for measuring the wave height and current direction and speed processes the GPS signals received with the GPS antenna 3 and measures the three-dimensional position of antenna 3. The three-dimensional position data are recorded by the data recording unit 4 connected to the GPS receiver 2. When the floating body 5 having those devices 2-4 installed thereon floats on the sea or ocean, it moves together with the waves and tidal current in the present location.

  • Publication number: 20040077966
    Abstract: Measuring electrodes are disposed in positions T5 and T6 according to the international 10-20 system. Electroencephalographic data obtained from these measuring electrodes is received in an input portion, and converted into phase analysis data on a phase plane V-dV/dt by a phase analysis portion. By use of a set of feature parameters selected from an aspect ratio, a V-axis maximum value, a sub/total revolution number ratio and an RL/UB distribution ratio in a feature parameter calculating portion, a Mahalanobis distance is calculated in a Mahalanobis distance calculating portion. The abnormality of the electroencephalogram is judged on the basis of the Mahalanobis distance, and a result of the judgment is outputted.
