Abstract: A pseudorandom signal generator uses two pseudorandom signals having a small correlation with each other to generate a cross-correlation function of the two pseudorandom signals, and to output a value of the cross-correlation function as a new pseudorandom signal. As the new pseudorandom signal as a result has random phases and random amplitudes, many new pseudorandom signals can be generated by the two existing pseudorandom signals.

Abstract: The present invention relates to an information processing unit, such as a mobile phone, equipped with a fingerprint sensor and reconciles size reduction with operability at a high level. The present invention is provided, adjacent to a operation panel, with a V-shaped groove which contains a first slope stretching away from the operation panel and slanting downward and a second slope stretching further away from the operation panel and slanting upward, where the V-shaped groove contains a fingerprint sweep sensor which detects a fingerprint on a finger moved along the first slope and the second slope.

Abstract: The present invention is arranged to use two pseudorandom signals having a small correlation with each other, to generate a cross-correlation function of the above-mentioned two pseudorandom signals, and to output a value of the above-mentioned cross-correlation function as a new pseudorandom signal; accordingly, the new pseudorandom signal per se has random phases and random amplitudes; thus, when there are a plurality of existing pseudorandom signals, a multitude of new pseudorandom signals can be generated by selecting two of the existing pseudorandom signals.
