摘要： A motorcycle-detecting device according to the present invention is mounted on an automotive vehicle. The device includes ultrasonic sensors for detecting objects around the vehicle, a device for predicting that a motorcycle is approaching the vehicle, and a device for adjusting a detection distance and a detection sensitivity of the ultrasonic sensors. When the predicting means predicts a motorcycle approach, the adjusting device makes the detection distance longer than a normal distance and the detection sensitivity higher than a normal sensitivity. Illuminating devices may be mounted on the vehicle to make the motorcycle passing by visible. A warning may be given to a driver when a motorcycle passing by is actually detected by the sensors. Information regarding the detected motorcycle may be given to other vehicles. According to the present invention, the motorcycle passing by the vehicle is surely and stably detected to thereby avoid any traffic accident with the motorcycle.

摘要： A system wherein management data for managing allowance or unallowance (i.e., prohibition) of copies on a recording medium are recorded, and a time restriction condition, an area limiting condition, a condition for restricting a copy mode, etc. are managed on the basis of the recorded copy management data. When data are copied to different recording media, the copy management data are recorded together with the main data, thereby restricting the reproducing operation of the main data.
