Title: Masashi Nakao: Innovator in Voice Monitoring Systems
Introduction
Masashi Nakao is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of technology, particularly in the development of innovative systems that utilize laser technology. With a total of 8 patents to his name, Nakao's work continues to influence various industries.
Latest Patents
One of Nakao's latest patents is a voice monitoring system that employs a laser beam. This system involves irradiating an infrared laser beam from a transmitter toward a window pane of a building. The reflected laser beam is then received by a receiver, where a laser spot captured by a CCD camera is displayed on target display units. The system includes a photo-cell that outputs an electric signal corresponding to the light energy of the reflected beam, and a knife edge that shields a portion of the reflected beam. The vibrational component of the window pane, caused by voice in the room, is detected as a positional change of the reflected beam. A beam detector, consisting of numerous light-receiving elements, is used to determine the installation place of the receiver. The transmitter scans the object with the modulated laser beam, making it easier to detect the reflected beam. When the reflected beam hits the beam detector, it emits a vibratory beep at an audible frequency. The XY coordinates of the scanning position are transmitted from the transmitter to the receiver and displayed on a coordinate display unit.
