  • Patent number: 9565628
    Abstract: Apparatus and method are provided for small cell energy saving. In one novel aspect, switch-off-request is broadcasted by the small cell detecting the low-load condition. The small cells upon receiving the switch-off-request message enter the frozen state, which prevents the small cells from switching off. In another novel aspect, the small cell in the low-load condition request measurement reports from the UEs. The UEs replies with the measurement-reports message, which includes the detected neighboring IDs and the UE's traffic load. The low-load small cell includes the information derived from the measurement-reports in the switch-off-request message. In another novel aspect, the small cell broadcasts the switch-on-request message. Upon receiving switch-on-acknowledge messages from switched-off neighboring small cells, the small cell selects one or more target cells to send the cell-activation-request.

  • Patent number: 9515544
    Abstract: A voltage compensation circuit and a control method thereof dynamically compensate a voltage drop caused by supplying power from a first power line to a function circuit. The voltage compensation circuit includes an amplifier, a detection module and a boosting module. The amplifier has an inverting input end coupled to the first power line and the function circuit to be supplied with a load voltage supplying to the function circuit, a non-inverting input end for being supplied with a reference voltage, and an output end coupled to the detection module to output a comparison signal. The boosting module is coupled between the detection module and the inverting input end of the amplifier. The detection module generates compensation voltage information according to the comparison signal. The boosting module outputs the compensation voltage to the inverting input end of the amplifier according to the compensation voltage information.

    Abstract: A non-violate memory device and a control method thereof are provided. The non-violate memory device includes a flip-flop, a retention cell and a memory cell. The flip-flop includes an output inverter. The flip-flop generates a second data according to a first data and a retention signal. The retention cell is coupled to the output inverter of the flip-flop. The retention cell temporarily stores the second data when the retention signal is enabled. During the period that retention signal is enabled, the memory cell stores the second data temporarily stored by the retention cell. Thus, another operation mode of the non-violate memory device is provided to save more power.

  • Patent number: 9270317
    Abstract: A chip card ejecting mechanism includes a main body, a tray assembled in the main body and configured to receive a chip card, and a door. The door includes a rotating end rotatably mounted on the main body and a push pole protruding from the rotating end. A resisting portion is located on an end of the push pole away from the rotating end. When the door is opened and the rotating end is rotated relative to the main body, the resisting portion resists against the chip card and drives the chip card to move out from the main body.
