Abstract: An object of the invention is to provide an information display device that displays information in a vehicle, can reduce the movement of the viewpoint of a viewer, and can obtain a large amount of image information. In order to achieve the object, there is provided an information display device that displays information in a vehicle and includes a first information display device that displays image information of a virtual image using reflection from a windshield of the vehicle, a second information display device that scans the windshield with laser light using a MEMS element to obtain a real image, and a third information display device using an instrument panel of the vehicle.

Abstract: An echo caused by sound leakage from a housing that vibrates due to a vibrating body is reduced. An electronic device (1) according to the present invention includes a piezoelectric element (30), a vibrating plate (10) that vibrates due to the piezoelectric element (30), microphones (42, 43), and an equalizer (44), the electronic device (1) causing the vibrating plate (10) to generate air-conducted sound and vibration sound that is transmitted by vibrating a part of a human body. The equalizer (44) makes a low-range emphasis setting, to emphasize a low frequency range more than a high frequency range of the air-conducted sound, when the volume of the air-conducted sound collected by the microphones (42, 43) exceeds a predetermined threshold.

Abstract: Systems, methods, devices, circuits for data processing, and more particularly, and more particularly to data processing relying on efficiency improved data detection.
