1. An information processing apparatus comprising:

  • a physical quantity detector unit which transforms a physical quantity into an electric signal and provides a detected value represented by the electric signal;

    a physical quantity determiner unit which determines whether the detected value provided by the physical value quantity detector unit is larger than a given threshold value;

    a timer unit which measures a time period during which it continues to be determined that the detected value is not larger than the given threshold value, in response to the determination that the detected value is not larger than the given threshold value after it is determined by the physical quantity determiner unit that the detected value is larger than the given threshold;

    a transmitter unit which transmits a request signal for requesting transmission of data, in response to the time period measured by the timer unit transcending a first given time threshold; and

    a receiver unit which receives transmitted data which is transmitted in response to the request signal.
