    • Disclosed is a distributed antenna system that selects an antenna in accordance with the position of a mobile terminal and reduces the variation in the total number of mobile terminals using each antenna while maintaining adequate communication quality. In the distributed antenna system in which a large number of antennas are distributively disposed, an antenna group including antennas having good communication quality is selected in accordance with the position of a mobile terminal. Further, in accordance with the communication quality and load status of a current antenna group and with the communication quality and load status of a post-change antenna group, which is obtained by changing some antennas in the current antenna group, the post-change antenna group is formed by changing some antennas in the current antenna group with which a mobile terminal using a heavily loaded antenna communicates.

    • To reduce an uplink interference in a network with a first base station of a large output and a second base station of a small output. Detecting the interference, the second base station urges the first base station to hand over a terminal causing it to the second base station. Multiple base stations and one or more terminals exist in this system, each terminal connects with one base station, and a serving base station is changed according to a communication state of each terminal. If the different second base station other than the first base station to which the terminal connects detects a large interference, the second base station will multicast transmit information for urging handover to the base stations except itself. The base station having received the information specifies a terminal giving the interference to the second base station, and makes it to be handed over thereto.
    • 减少具有大输出的第一基站和小输出的第二基站的网络中的上行链路干扰。 检测到干扰,第二基站敦促第一基站将终端移交给第二基站。 在该系统中存在多个基站和一个或多个终端,每个终端与一个基站连接,并且根据每个终端的通信状态改变服务基站。 如果除了终端所连接的第一基站之外的不同的第二基站检测到大的干扰,则第二基站将组播用于促使切换到除了自身之外的基站的传输信息。 已经接收到该信息的基站指定向第二基站发送干扰的终端,并且将其移交给其。

    • Various forms of vehicle driving energy are provided for vehicles, such as gasoline vehicle, hybrid vehicle, ethanol vehicle, electric vehicle and fuel cell vehicle. In such circumstances, an index is desired by vehicle purchasers, which has a viewpoint on the benefit to be obtained by using an electricity storing section of a vehicle for other than running the vehicle, and with which the economic efficiencies of those vehicles can be more clearly compared/examined, in the correlation between the prices of the abovementioned vehicles using various vehicle drive energy modes, and the fuel consumption and the drive energy consumption costs thereof. To display evaluations of vehicles in various drive energy modes, by dividing a fuel efficiency numerical value by a vehicle price. In addition, to achieve a vehicle evaluation/comparison at the time of purchasing a new car, by setting a planned running distance.

    • A boat propelling system capable of determining an abnormality regarding steering of a propelling system main body includes an outboard engine main body, a steering section arranged to steer the outboard engine main body, a steering angle sensor arranged to detect a steering angle of the steering section, a pivot sensor arranged to detect an actual pivot angle of the outboard engine main body, and an ECU. The ECU calculates a target pivot angle change amount based on a target pivot angle derived from the steering angle and a baseline target pivot angle, calculates an actual pivot angle change amount based on the actual pivot angle and a baseline actual pivot angle, and obtains a gap amount between the target pivot angle change amount and the actual pivot angle change amount. Then, the ECU determines an abnormality regarding steering of the outboard engine main body based on a result of comparison between the gap amount and the first threshold value. Setting of the baseline target pivot angle and the baseline actual pivot angle is based on a result of a comparison between the gap amount and a second threshold value.
