    • The invention relates to a method for provision of a drive signal for a switch which controls the current drawn by an inductive energy storage element in a power factor correction circuit in which a control signal which controls the power consumption is available. One drive cycle of the switch comprises: detection of a predetermined storage state of the inductive energy storage element; when the predetermined storage state of the storage element is detected, production of a switching-on level for the drive signal for a regular switched-on duration which is dependent on the control signal or for a maximum switched-on duration which is dependent on an input voltage, when the regular switched-on duration is greater than the maximum switched-on and production of a switching-off level for the drive signal for a switched-off duration until the next detection of the predetermined storage state.
    • 本发明涉及一种用于提供开关的驱动信号的方法,所述开关控制由功率因数校正电路中的感应能量存储元件引起的电流,其中控制功率消耗的控制信号可用。 开关的一个驱动周期包括:检测感应能量存储元件的预定存储状态; 当检测到存储元件的预定存储状态时,产生取决于控制信号的正常接通持续时间的驱动信号的接通电平或取决于控制信号的最大接通持续时间的接通电平 输入电压,当常规接通持续时间大于最大接通时间时,产生用于关断持续时间的驱动信号的关断电平,直到下一次检测到预定的存储状态。

    • A system and method for selectively providing call forwarding from a mobile communication device to a telephone number includes a radio frequency identification (RFID) device associated with the telephone number. The mobile communication device interrogates the RFID device when the mobile communication device is in proximity to the RFID device. The RFID device responds by transmitting an identifier for identifying a telephone number to the mobile communication device. The identifier may include an identification code, a telephone number, a pointer, or the like. The mobile communication device may then selectively provide call forwarding to the telephone number identified from the identifier provided by the RFID device.
