A game apparatus is capable of controlling infrared radiation means for radiating infrared light. The game apparatus executes game processing using imaging information on the infrared light obtained from an input device. The input device takes an image of the infrared light radiated by the infrared radiation means, and also receives an input from a user. The game apparatus comprises pattern storage means; selection means; and radiation control means. The pattern storage means stores at least one signal pattern of an infrared signal usable by a control target device. The selection means selects at least one of the at least one signal pattern stored by the pattern storage means, using the input received by the input device. The radiation control means causes the infrared radiation means to output an infrared signal of the signal pattern selected by the selection means.

The power flow model of the multiterminal voltage-source converter-based high voltage DC (M-VSC-HVDC) transmission system for large-scale power systems is studied.

A unified procedure is developed for incorporating the proposed model into the conventional Newton-Raphson power flow solver. The IEEE 300-bus test system embedded with multiple HVDC transmission systems under different configurations are investigated. Simulation results reveal that the proposed model is effective and accuracy in meeting various control objectives.

An SOC target is a control target of a remaining capacity of an accumulation device having a characteristic that the internal loss increases in a low SOC region. The SOC target is set to a first value corresponding to a remaining capacity target upon reaching a predetermined point when the remaining travel distance up to a predetermined point where the accumulation device can be charged from outside has become shorter than a predetermined distance. Thus, the hybrid vehicle can perform EV travel by power consumption of the accumulation device. On the other hand, when the remaining travel distance is not smaller than the predetermined distance Dr, the SOC target is set to a second value in the SOC region where the loss of the accumulation device is smaller than the first value. Thus, it is possible to reduce the power consumption in the hybrid vehicle which performs such a remaining capacity management that the remaining capacity of the accumulation device upon arrival at a predetermined point is a predetermined value.

An error output controller controls the output of the error values detected by the error detector in accordance with the state of the flag information generated by the generator.

This invention relates to a transmission power control method and transmission power control apparatus in a mobile communication system. The reception quality of a signal (31, 32a, 32b, 41, or 42) transmitted from another mobile station (51 or 52) or base station (21 or 22) is compared with a predetermined control target value such as a signal-to-interference ratio.

With this operation, when a propagation environment such as multibus or moving speed changes, the control target value for transmission power control is changed within a short period of time, and channel quality is maintained constant, thus realizing desired channel quality.
