  • Publication number: 20100306758
    Abstract: When data received separately in first and second reception processing is processed separately by first and second application programs, and when data received by the first reception processing contains specific data specifying processing by the second application program, and the specific data has regional properties, the current region where the second application program is executed is judged, and if the region does not match a region to which processing specified by the specific data belongs, the content specified by the specific data is converted based on data in a predetermined table, and processing is executed by the second application program. Accordingly, two application programs can be linked in a mobile phone unit or other terminal devices, and problems when executing one application with regional properties under control of the other application can be resolved.

  • Publication number: 20100266914
    Abstract: A fuel cell system is turned off without using up the electric power of a secondary battery in the case where a fuel cell fails to start up, while reducing the startup time of the fuel cell system. When an ignition key is turned on, a controller calculates allowable waiting time for a fuel cell to start up on the basis of the electric power stored in a secondary battery. If the fuel cell fails to start up during the period of time from the instant the ignition key was turned on until the allowable waiting time elapses, then the controller turns on an alarm lamp which indicates the startup failure of the fuel cell. Meanwhile, in the case where the fuel cell starts up, the controller begins a normal operation in which a traction motor and the like are actuated by using the electric power generated by the fuel cell and the electric power stored in the secondary battery.

  • Publication number: 20100255393
    Abstract: It is possible to suppress over-discharge of an accumulator even when the accumulator is in charge-limited state in a fuel cell output control device. A vehicle drive control system including a fuel cell and an accumulator uses a control unit having: an FC output instruction value calculation module which calculates an output instruction value of a fuel cell according to a power required by a rotary machine; a regeneration limit judgment module which judges whether regeneration is limited for the rotary machine; a battery limit judgment module which judges whether charge of the accumulator is limited; and a required power correction module which corrects the required power of the fuel cell when the charge of the accumulator is limited and neither of the fuel cell or the rotary machine generates power, so as to limit discharge from the accumulator.

  • Publication number: 20100239930
    Abstract: In the event that at least a portion of unit cells in a fuel cell stack have experienced a significant drop in voltage, the fuel cell system will execute a voltage recovery process allowing them to recover generating capability. In the voltage recovery process, a controller measures impedance of the fuel cell stack, and based on these measurements, determines the hydration condition of the electrolyte membrane inside the fuel cell. If, during the determination of hydration condition, the controller has determined that the hydration level is low, a current limiting process for temporarily limiting output of the fuel cell in order to recover generating capability will be triggered under more lenient conditions, as compared to if determined that the hydration level is high.

  • Publication number: 20100233557
    Abstract: Whether a gas leakage occurs or not is accurately determined in a simple configuration. When receiving a request for activation of a fuel cell, a control unit opens a main shutoff valve to start hydrogen gas supply from a hydrogen tank to the fuel cell. The control unit thereafter performs gas leakage determination processing for a hydrogen piping system. If it is determined in the gas leakage determination processing that a gas leakage occurs, a gas leakage alert is output to stop the activation of the fuel cell. If it is determined in the gas leakage determination processing that a gas leakage does not occur, a compressor is activated to start oxidant gas supply to the fuel cell, and the fuel cell continues being operated.

  • Publication number: 20100209792
    Abstract: Provided is a fuel cell system that can change the number of active phases in a DC/DC converter in order to prevent overcurrent from flowing through one point (e.g., a reactor of the DC/DC converter) in the system. In step S1, whether or not the system is in a state that causes a rapid change in a voltage command value is checked. If the system is in a state that causes a rapid change in the voltage command value, the processing goes to step S2, and if not, the processing goes to step S3. In step S2, a DC/DC converter is prohibited from being driven in a single phase and the processing ends. In step S3, the DC/DC converter is permitted to be driven in a single phase and the processing ends.

  • Publication number: 20100168966
    Abstract: A saddle riding type vehicle includes a balancer beam rotatably mounted on a vehicle body to cause a right wheel and a left wheel to move up and down in opposite directions, and is capable of making turns by leaning the vehicle body. The saddle riding type vehicle also includes a headlight, a drive mechanism arranged to rotate the headlight, a front detector arranged to detect a rotation angle of the balancer beam relative to the vehicle body, and a controller programmed to control the drive mechanism based on a result of detection by the front detector. The rotation angle detected by the front detector corresponds to an angle of the vehicle body leaning sideways relative to a traveling surface (relative lean angle). The controller controls the drive mechanism based on such result of detection by the front detector. The headlight can therefore illuminate directions of movement properly.

  • Publication number: 20100119898
    Abstract: Provided is a fuel cell system capable of ensuring that the fuel cell system can start next time and preventing scavenging processing from being continued for an unnecessarily long time. An impedance comparator 150 compares an impedance reference value ins stored in a memory 151 with a measured impedance stored in a measurement memory 152, and determines whether or not the amount of water remaining in the system falls below a threshold value. On the other hand, an SOC comparator 170 compares an SOC reference value stored in a memory 171 with a detected SOC stored in an SOC memory 172, and determines whether or not the detected SOC falls below the SOC reference value. A scavenging control section 160 performs scavenging control based on both of the determinations above.

  • Publication number: 20100112390
    Abstract: The progress of activation of a fuel cell is appropriately transmitted in accordance with the rise of the temperature of the fuel cell, and an estimated time till the completion of the activation is displayed with higher accuracy. To realize this, the current percentage of a fuel cell temperature is displayed on a gauge (G) which displays, as a starting point, the temperature of the fuel cell at the start of the activation and which displays, as an end point, the temperature of the fuel cell at the completion of the activation. The percentage of the temperature is displayed as the estimated time till the completion of the activation, whereby an adverse effect due to a low accuracy in the case of the estimation of the time is eliminated. When the fuel cell is activated for a failure check, the percentage of an actually elapsed time with respect to a time required to complete the failure check may be displayed on the gauge (G).

  • Patent number: 7526311
    Abstract: At a mobile terminal apparatus provided with a non-contact IC, flexible communication is carried out between the external reader/writer , non-contact IC and the internal application manager controller, and a program designated in the form of a push from the external reader/writer is activated and executed in a smooth manner at the mobile terminal apparatus. Normally, the non-contact IC cannot communicate with the application manager controller during communication with the external reader/writer, and cannot communicate with the external reader/writer during communication with the application manager controller. A specific command is transmitted from the external reader/writer together with information specifying a prescribed application during communication between the external reader/writer and the non-contact IC. When the specific command is received, the non-contact IC shifts to a communication state enabling communication with the application manager controller.
