  • Patent number: 12055092
    Abstract: The hydrogen supply device includes a liquid hydrogen pump that boosts the pressure of liquid hydrogen stored in a liquid hydrogen tank, a vaporizer that converts the liquid hydrogen discharged from the liquid hydrogen pump into hydrogen gas, a pressure chamber that a hydrogen gas that flows out from the vaporizer is filled with and that supplies the filled hydrogen gas to a hydrogen engine, and a pump control unit. The pump control unit controls the discharge flow rate of the liquid hydrogen pump so that the actual pressure in the pressure chamber becomes a target pressure based on the hydrogen flow rate supplied to the hydrogen engine, the actual pressure in the pressure chamber, and the rotation speed of the hydrogen engine. At the same time, the target pressure of the pressure chamber is changed according to the rotation speed of the hydrogen engine.

  • Patent number: 8600957
    Abstract: Provided is a mesh data creation method allowing appropriate expression of population densities while making a balance between accuracy and granularity. In the mesh data creation method, when the number of samples in a region of reference mesh data with a predetermined size is not less than a threshold, divided mesh data is created by dividing the region of the reference mesh data. Namely, each portion with a high population density can be expressed by a fine region of mesh data and each portion with a low population density by a coarse region of mesh data. The above makes it feasible to prevent meshes from becoming too fine to ensure accuracy or, conversely, from becoming too coarse to maintain granularity, thereby resulting in failing to achieve a detailed grasp of population densities, and thus to achieve appropriate expression of population densities while making a balance between accuracy and granularity.

    Abstract: An information processing device and a method for estimating a number of terminals, which can accurately count a number of mobile terminals in an analysis target region of which address attribute is an adjacent region, taking the intake phenomenon into account. A terminal counting portion counts numbers of first and second position information pieces. An intake coefficient calculation portion calculates an intake coefficient based on the numbers of position information pieces. An intaked terminal calculation portion calculates a number of intaked terminals based on the counted number of position information pieces at an analysis target time and the calculated intake coefficient, subtracts the number of intaked terminals from the number of position information pieces, and calculates an estimated number of mobile terminals.

  • Patent number: 8509820
    Abstract: In a location identifying method, the sight of users of mobile communication terminals is estimated by calculating directions of the users based on position information of the mobile communication terminals, and the location where the lines of sight of the users are concentrated is identified based on the estimated sight. By identifying a location where the lines of sight of the users of the mobile communication terminals are concentrated, it is possible to identify an installation location where high advertising effectiveness can be achieved. Moreover, since only acquisition of the position information of the mobile communication terminals is needed, it is possible to efficiently identify an installation location of an advertisement, etc. Therefore, it is possible to efficiently identify an installation location of an advertisement or a billboard where high advertising effectiveness can be achieved.

  • Publication number: 20130203377
    Abstract: To estimate the number of mobile terminals that have been staying in an observation area for a desired period of time, the feature quantity calculation portion 17 calculates a feature quantity for observation target location data based on location acquisition time information contained in the observation target location data acquired by the observation target acquisition portion 15. The expected stay time calculation portion 18 calculates an expected stay time in an observation area to be observed and, based on the expected stay time, the passing/staying terminal selection portion 19 selects mobile terminals to serve as a target of terminal quantity estimation. Then, the terminal quantity estimation portion 20 estimates the number of mobile terminals calculated as the target of estimation. In this manner, the terminal quantity estimation device 10 estimates the number of mobile terminals that have been staying in the observation area for a desired period of time.
