| 20100332870 | ELECTRONIC DEVICE FOR REDUCING POWER CONSUMPTION OF COMPUTER MOTHERBOARD AND MOTHERBOARD THEREOF - An electronic device for reducing power consumption of a computer motherboard is disclosed. The electronic device enables the computer motherboard to compel interruption of power supply to a south bridge chip and a super input output (SIO) chip of the computer motherboard so as to save power while the computer motherboard is waiting for receipt of a Wake-on-LAN packet. A network chip of the computer motherboard sends a signal to the power-saving electronic device as soon as a Wake-on-LAN event occurs, such that a standby power is electrically connected to the south bridge chip and the SIO chip by the electronic device. The computer motherboard equipped with the electronic device is capable of executing Wake-on-LAN function while compelling interruption of power supply to the south bridge chip and the SIO chip in a power-saving state. | 12-30-2010 |

| 20100125743 | ELECTRONIC DEVICE FOR REDUCING POWER CONSUMPTION DURING OFF OF COMPUTER MOTHERBOARD - The present invention discloses an electronic device for reducing power consumption during power off of computer motherboard. When the computer motherboard is at S5 soft off state of ACPI, it will make the computer motherboard enter like G3 mechanical off state of ACPI. The electronic device will cut off a portion of electric components consuming stand-by power on the computer motherboard, and only supply the stand-by power to the electronic device itself. Only after the user pressed the power button, the electronic device will connect the stand-by power to the computer motherboard. | 05-20-2010 |

| 20100084180 | ELECTRONIC DEVICE WITH A SHIELDING MEMBER - An electronic device includes a circuit board and a shielding member. The circuit board includes a pair of frames and a plurality of mounting holes disposed between the frames. The pair of frames surround at least one electronic component positioned within an area defined within the pair of frames. The shielding member is configured for shielding the electronic component from electromagnetic interference (EMI), and includes a top wall, a plurality of sidewalls, and a plurality of mounting portion extending from end portions of the sidewalls. The top wall and the sidewalls cooperatively bound a receiving space to receive the at least one electronic component. The mounting portions are received in the corresponding mounting holes to attach the shielding member to the circuit board. | 04-08-2010 |

| 20090271019 | SYSTEM AND METHOD OF DEMAND AND CAPACITY MANAGEMENT - Systems of demand and capacity management with machine-time accuracy are provided. The system includes an allocation planning module, an order management module, a capacity model, and a capacity management module. The allocation planning module receives a demand plan for a product. The capacity management module transforms the demand plan into a machine-time-based plan according to the capacity model, and reserves capacity according to the machine-time-based plan for the demand plan. The capacity management module further transforms a purchase order received by the order management module before a cutoff date for the product into a machine-time-based order, accepts the machine-time-based order and decreases the reservation capacity depending on the machine-time-based plan. | 10-29-2009 |

| 20100289467 | POWER SUPPLY CIRCUIT AND METHOD THEREOF - In a normal mode, the power supply is fed back in a close loop, but in a power saving mode, the power supply is fed back in an open loop. When it is detected that the power supply is continuously fed back in the open loop and in a substantially zero output status, the power supply circuit enters a power down status. If the back-stage circuit needs power supply again, then the feedback is switched to the close loop and the power supply circuit enters the normal mode. | 11-18-2010 |
