Abstract: Methods and systems are provided for controlling network service quality. According to an aspect of the invention, a computer-implemented method is provided for controlling levels of quality of service (QoS) for transmitting data between a terminal and a destination. The method comprises enforcing a first level of a QoS to a connection between the terminal and the network, receiving a user-requested, second level of the QoS from the terminal, identifying a currently-available level of the QoS on the network, determining a third level of the QoS based at least in part on the currently-available level of the QoS on the network and the second level of the QoS, and enforcing the third level of the QoS. Methods and system are provided for enabling users at the terminals to specify online a level of network QoS, and the system dynamically changes the quality level and the plan to satisfy the request.

Abstract: A vehicle driving mode display device judges whether or not a following first condition or a following second condition is satisfied in a case that a vehicle is driven within a tolerance range, and if satisfied, issues a warning. The first condition is a case in which a difference between a standard speed indicated by the running speed pattern and the vehicle speed is gradually widened as time elapses. The second condition is a case in which the vehicle speed exceeds the tolerance range within a predetermined allowable time period when an acceleration at the moment is presumed to be kept.
