  • Patent number: 10466655
    Abstract: A processor controls an oscillation circuit such that a frequency of a clock signal is close to a reference frequency based on a frequency of a carrier wave of a standard radio wave and the frequency of the clock signal. In this manner, since the processor controls the frequency of the clock signal by using the carrier wave of the standard radio wave of which the frequency is managed with high accuracy, it becomes possible to improve accuracy of an internal time.

  • Publication number: 20190196415
    Abstract: A processor outputs selected frequency information from standard radio wave frequency information, GPS frequency information, LPWA frequency information, and mobile phone frequency information, and controls an oscillation circuit such that a frequency of a clock signal is close to a reference frequency. Accordingly, even in a case where an environment of an electronic device changes, it is possible to improve accuracy of an internal time by correcting a frequency of the clock signal by using a radio wave appropriate for the environment after the change.

  • Patent number: 8902162
    Abstract: A screen is provided on a housing in such a manner that the screen protrudes toward its nearer side, and is inclined so that the nearer side becomes lower. This screen displays thereon a first hierarchy menu for indicating an arrangement of genre pictures, a second hierarchy menu for indicating an arrangement of commodity pictures, and a map image for indicating a map of the sales counters. A user brings his or her hand tip nearer to this screen. This operation allows a double-ring pointer to be displayed at a position which corresponds to the spatial position or direction of the user's hand tip relative to the screen. On this screen, the user is permitted to change the position of this double-ring pointer by performing a gesture of changing the spatial position or direction of the user's hand tip.
