By use of feature parameters generated likewise from a reference learning electroencephalographic data set input from a reference learning electroencephalographic data set input portion, a reference data space calculating portion calculates a mean, a variance, and an inverse matrix of a correlation matrix of the reference learning electroencephalographic data set. These are used as a reference data space.

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.

Abstract: The present invention provides contact sensors capable of determining the pressure distribution over the whole surface of each of joint units having a cylindrical shape, both end portions of which are cut at an offset angle, and constituting robot arms. In order to provide a technology enabling real-time drive control of the robot arms by using detected values from these sensors, the points of intersection of the electrodes are distributed across the whole surface of each joint by forming a pressure-sensitive sheet sensor in which column electrodes arranged in parallel, and row electrodes arranged in a wound-string shape, are combined, these joints having a cylindrical shape, both end portions of which are cut at an offset angle. In addition, by making an electrode structure that covers a prescribed width in both rows and columns, the number of signal output terminals is reduced and the operation processing load is lightened.
