Abstract: A driving control system 1 includes a camera unit 11 and a transceiver 18 which are mounted to a vehicle 5. The driving control system 1 also includes a transceiver 74, an information recognition_ECU 72 which recognizes road traffic information based on first road traffic detection information received by the transceiver 74 through the transceiver 18, and a traveling_ECU 73 which computes control information for the vehicle 5 based on the road traffic information, which are provided to a traffic control apparatus 70 disposed in each predetermined traffic control area. The driving control system 1 also includes an E/G_ECU 23, a PS_ECU 24, and a BK_ECU 25 which are mounted to the vehicle 5 and execute driving control based on the control information received by the transceiver 18 through the transceiver 74.

Abstract: A travelling control system includes a plurality of vehicles each including a controller, a server including a generator configured to generate a travelling control information for the plurality of vehicles, a predictor configured to predict a merging interference between a first vehicle travelling from a merging road toward a main road and a second vehicle travelling on the main road, a sender which is provided in the first vehicle to send an interference suppressing request, and a receiver which is provided in the second vehicle to receive the interference suppressing request. The controller of the second vehicle travelling on the main road is configured to execute interference suppressing control of suppressing an approach of the second vehicle to the first vehicle travelling from the merging road to the main road, in a case that the receiver receives the interference suppressing request from the first vehicle.

Abstract: A sound pickup device, which is arranged in proximity to a percussion instrument (e.g., a bass drum), comprises a diaphragm stretched under tension over an opening of a shell having a cylindrical shape, and an electroacoustic transducer arranged inside of the shell. The electroacoustic transducer comprises a magnetic transducer or a speaker unit. Herein, the percussion instrument is played to produce the low-pitch sound, which is transmitted to the diaphragm to vibrate so that the electroacoustic transducer is activated to convert the low-pitch sound into an electric signal, based on which the low-pitch sound is reproduced by a sound system with a high fidelity to the original sound.
