  • Patent number: 9589082
    Abstract: The present invention relates to a data processing device, a data processing method, and a program which enable prediction to be performed even when there is a gap in the current location data to be obtained in real time. A learning main processor 23 represents movement history data serving as data for learning, as a probability model which represents a user's activity, and obtains a parameter thereof. A prediction main processor 33 uses the probability model obtained by learning to estimate a user's current location from movement history data to be obtained in real time. In the event that there is a data missing portion included in movement history data to be obtained in real time, the prediction main processor 33 generates the data missing portion thereof by interpolation processing, and estimates state nose series corresponding to the interpolated data for prediction.

  • Patent number: 9537380
    Abstract: A permanent-magnet type rotating electrical machine, including a rotor including a plurality of magnetic poles arranged at an equal interval, and a stator including a plurality of teeth and a plurality of armature windings. A high frequency voltage different in frequency and amplitude from voltages for generating a torque is applied to the armature windings. A magnetic pole position of the rotor is estimated by using a current trajectory of a measured high frequency current. When dq transform is applied to the measured high frequency current, a current trajectory forms an ellipse on d and q axes. Angular variation ranges of a major axis of the ellipse with respect to a load current and a rotor position are set so as to acquire a predetermined position estimation resolution.

  • Patent number: 9285235
    Abstract: The present technique relates to an information processing device, an information processing method and a program which can accumulate sufficient movement history data with a little power consumption. A similarity search unit searches for a past route similar to the immediate movement history which is acquired by a position sensor unit and which has time series position data, from the search data stored in a past history DB. A fitness determination unit determines whether or not goodness of fit of the past route searched by the similarity search unit and the immediate movement history is a predetermined threshold or more. A sensor control unit controls an acquisition interval of the position data of the position sensor unit according to a determination result of the fitness determination unit. The technique of this disclosure is applicable to a prediction device which, for example, acquires position data and predicts a predicted route.

  • Patent number: 9130501
    Abstract: A storage section stores, as stored current values, currents flowing when a voltage application section applies voltage vectors to a three-phase rotary machine. A position estimation section estimates the rotor position of the rotary machine in a stopped state based on the stored current values. An adjustment section adjusts a minimum necessary application time that allows the rotary machine to be magnetically saturated by voltage vector application, to enable rotor position estimation. Further, the adjustment section uses, as an adjustment evaluation value, the magnitude |?Y| of differential admittance obtained by dividing a summed current value calculated from the stored current values by the voltage amplitude value of the voltage vector instruction when the voltage vector based on the voltage vector instruction is applied with the application time being set at an arbitrary application time, and adjusts the application time based on |?Y|.
