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 translation: 使用超声波的助听装置被插入并安装在耳朵的外耳道内，通过通过麦克风接收的声音信号的单边带幅度调制产生超声波波段信号，并输出超声波波段 信号和用于单边带幅度调制的载波信号作为预定波束方向的传输介质的超声波信号。 因此，超声波信号在损伤的听觉器官区域中形成焦点区域，通过焦点区域中的转印介质的非线性特性将超声波波段信号恢复为声音信号，并且损伤的听觉器官检测声音信号。

Abstract: Provided is a laser scanner. The laser scanner includes a laser transmitter configured to output a laser radiated towards an object, a laser receiver configured to receive a laser reflected from the object, and an oscillating mirror of which a mirror surface is coated with a thin metal film to reflect the received laser reflected from the object and be penetrated by an electromagnetic wave incident from an outside the laser scanner. The received laser reflected from the object is reflected by the mirror surface of the oscillating mirror coated with the thin metal film and received by a laser receiver, and the electromagnetic wave incident from the outside the laser scanner penetrates the mirror surface of the oscillating mirror and then dissipates.
