  • Patent number: 10298459
    Abstract: A method includes: receiving a reservation, made by a user from a user terminal, regarding a bandwidth of a line; first determining whether or not a total bandwidth of a bandwidth demanded by the reservation in a time slot related to the received reservation and a guaranteed bandwidth to one or more reserved users exceeds a permissible upper limit value of the line; when the total bandwidth exceeds the permissible upper limit value, calculating a reducible bandwidth based on a bandwidth shortage produced by subtracting the permissible upper limit value from the total bandwidth and statistical information of a use bandwidth consumed by the one or more reserved users; second determining a reduction bandwidth reduced from the guaranteed bandwidth based on the calculated reducible bandwidth; and assigning, by a processor, the determined reduction bandwidth to the bandwidth demanded by the reservation.

  • Patent number: 10286979
    Abstract: A motorcycle is provided with an engine unit having a crankcase and a cylinder assembly protruding diagonally frontward and upward from the crankcase. An air cleaner box has a rearward-descending shape extending from the upper side to the rear side of the cylinder assembly as seen in a side view to form a vertically elongating box shape. The air cleaner box is disposed between left and right frames of a chassis, and both side surfaces of the air cleaner box are separated from the chassis. The air cleaner box has a frontward-narrowing and rearward-narrowing width as seen in a top view. As a result, it is possible to obtain a sufficient box capacity and facilitate a compact design. In addition, it is possible to smoothly flow an air stream in the lateral sides of the air cleaner box.
