Abstract: A hearing-aid apparatus using ultrasonic waves is inserted and mounted within an external auditory meatus of an ear, generates an ultrasonic wave band signal by single side band amplitude modulation of a sound signal that is received through a microphone, and outputs the ultrasonic wave band signal and a carrier signal that is used for single side band amplitude modulation as an ultrasonic wave signal to a transfer medium in a predetermined beam direction. Therefore, the ultrasonic wave signal forms a focal area in a damaged hearing organ area, the ultrasonic wave band signal is restored to a sound signal by nonlinear characteristics of a transfer medium in the focal area, and the damaged hearing organ detects the sound signal.

Abstract: Provided are a random number generating device and an operating the same. The random number generating device includes a particle detector, a pulse generator, a clock counter, and a random number converter. The particle detector detects particles emitted from a radioactive isotope. The pulse generator generates pulses corresponding to the particles. The clock counter counts the number of clocks during time intervals between the pulses and generates a plurality of count values. The random number converter adjusts a clock frequency, based on a minimum value and a maximum value of the plurality of count values and converts a target count value generated depending on the adjusted clock frequency into a random number.
