Abstract: A flyback power converter includes a power transformer, a first lossless voltage conversion circuit, a first low-dropout linear regulator and a secondary side power supply circuit. The first low-dropout linear regulator (LDO) generates a first operation voltage as power supply for being supplied to a sub-operation circuit. The secondary side power supply circuit includes a second lossless voltage conversion circuit and a second LDO. The second LDO generates a second operation voltage. The first operation voltage and the second operation voltage are shunted to a common node. When a first lossless conversion voltage is greater than a first threshold voltage, the second LDO is enabled to generate the second operation voltage to replace the first operation voltage as power supply supplied to the sub-operation circuit; wherein the second lossless conversion voltage is lower than the first lossless switching voltage.

Abstract: A power saving method for a peripheral device in a wireless operation mode is provided. The power saving method at least includes the steps of allowing the peripheral device to enter an idle mode and judging whether the peripheral device receives a startup trigger event. In the idle mode, the light source in an operation region of the peripheral device is in an on state or a high-brightness state. If the peripheral device receives the startup trigger event, the peripheral device is switched from the idle mode to a power saving mode. In the power saving mode, the light source in the operation region of the peripheral device is in an off state or a low-brightness state. The peripheral device in the power saving mode consumes less electric power than the peripheral device in the idle mode.

Abstract: A cloud radio access network system includes remote signal sources, a baseband processing unit pool, an access management server, a software defined network controller and a network signal forwarder. Each remote signal source is configured to transmit an access signal. The baseband processing unit pool provides a baseband processing signal.

The mainframe has an accommodating slot to accommodate the insert module. The latching shaft is pivoted at a side of the accommodating slot of the mainframe, and has a retainer and a bulge. When the retainer is engaged with a recess of the insert module, the insert module is fixed within the accommodating slot. The resetting component is disposed on the mainframe for driving the latching shaft that has been forced to rotate returning to the original position. The latching rod is forced to move, so as to bear against and push the bulge of the latching shaft, thereby driving the latching shaft to rotate.
