A novel information processing apparatus includes an energy-saving mode controller that controls the information processing apparatus in an energy-saving mode, and a restart controller that restarts the energy-saving mode controller each time a predetermined value is counted using a counter. A flat plate antenna for ground waves is fixed on a printed board, and a two-point feeding type patch antenna is placed and fixed on a metallic flat plate of the plate antenna. The reading meter system may be used alone andor in connection with an emotional response tool. The sensing system makes possible the synergistic, and simultaneous, analysis of both IR and Raman data in an integrated device.
