Abstract: An electronic device including a signal unit configured to emit a first radiated signal to a subject; a signal receiving unit configured to detect a reflected signal of the first radiated signal from the subject; and a controller configured to determine whether a distance to the subject is calculated based on the reflected signal of the first radiated signal, change a waveform of the first radiated signal when the distance is not calculated, cause the signal output unit to emit a second radiated signal with the changed waveform, detect, via the signal receiving unit, a reflected signal of the second radiated signal from the subject, and calculate the distance to the subject based on the reflected signal of the second radiated signal.

Abstract: The present invention relates to a control circuit system of a pair of mobile terminals comprising a first mobile terminal and a second mobile terminal. The first mobile terminal comprises a first display unit, a first fastening unit, a proximity sensor for recognizing a connection with the second mobile terminal, and a first control circuit including a first near-field communication module and a first signal aggregator for transmitting/receiving a signal to and from the second mobile terminal. The second mobile terminal comprises a second display unit, a second fastening unit connected to the first fastening unit, and a second control circuit including a second near-field communication module and a second signal aggregator for transmitting/receiving a signal to and from the first mobile terminal. A signal transmitted from the first near-field communication module is received by the second near-field communication module and displayed on the second display unit.
