  • Publication number: 20140116524
    Abstract: A fluid supply system includes a tank, a shutoff valve, a fluid fill channel, a fluid supply channel, a fill detector, a pressure detector, and a controller. The shutoff valve includes a shared channel to enable fluid to flow from a fill hole to the tank and to flow from the tank to a fluid usage device. The pressure detector is provided in the fluid supply channel. The controller is configured to output a close instruction to the shutoff valve and configured to execute a processing to determine open valve malfunctions in the shutoff valve based on changes in pressure values which are input from the pressure detector. The controller stops the processing to determine open valve malfunctions when the fill detector detects that the fluid supply system is in the supplying state.

  • Publication number: 20140089701
    Abstract: A method may include associating, with a timer-B, a second application in a terminal device; setting the terminal device in a standby mode; and executing the second application when a processor in the terminal device wakes up after the timer-B measures a second amount of elapsed time. The timer-B may not initiate wake-up of the processor. The method may further include determining whether the second application is associated with the timer-B or a timer-A when the terminal device receives a command of setting the terminal device in the standby mode; and when the second application is determined as being associated with the timer-A, unassociating the second application with the timer-A. The timer-A may initiate wake-up of the processor when the timer-A measures another second amount of elapsed time while the terminal device is the standby mode. A timer associated with a first application may initiate wakeup of the processor.

  • Patent number: 8395339
    Abstract: A motor control device that has a high-frequency component, and a DC bias component that has a magnitude which causes a motor to be magnetically saturated and take on a certain value over a predetermined period, and is positively and negatively symmetrical are impressed as an observation command on a d-axis current command. The polarity of the magnetic pole of a permanent magnet is identified based on a relationship of large and small magnitudes between a first amplitude, which is attained during a period during which a DC bias component takes on a positive certain value, among amplitudes of a high-frequency component contained in a d-axis response voltage computed based on a feedback current respondent to the observation command, and a second amplitude attained during a period during which the DC bias component takes on a negative certain value.
