Title: Kazuyuki Takizawa: Innovator in Portable Communication Technology
Introduction
Kazuyuki Takizawa is a notable inventor based in Chigasaki, Japan. He has made significant contributions to the field of portable communication devices, holding a total of 6 patents. His innovative designs focus on enhancing user experience and functionality in communication technology.
Latest Patents
One of Takizawa's latest inventions is a portable terminal device that can extrapolate the position of a sound source in the thicknesswise direction, regardless of the user's style. This slide-type portable terminal features an upper casing, a lower casing, and a coupling part that allows for adjustable positional relations. The upper casing is equipped with multiple first microphones, while the lower casing contains a second microphone. In a handhold style, one of the first microphones and the second microphone are aligned in the thicknesswise direction of the device. As the upper casing slides, the other microphone aligns accordingly, enabling the extrapolation of sound source position from the output signals of the formed microphone array.
Another significant patent is a communication terminal apparatus designed to improve the quality of additional functions, such as image processing and music reproduction, while minimizing power consumption. This apparatus includes a transmission and reception unit for voice and image signals, a decode processing unit, and two control circuits for managing power supply. Notably, if the device is inactive for a specified duration, the second power supply unit reduces power to the second control circuit, enhancing energy efficiency.
