  • Publication number: 20120173898
    Abstract: A remote-controlled computer system includes a computer system electrically linked to a remote control device. The remote control device receives a manual operation to generate a manual trigger signal sent to the computer system. The computer system includes a motherboard, a power supply and a status control unit. The motherboard receives continuously the manual trigger signal and sends a power ON/OFF signal to start or stop the power supply. The power supply provides electric power to the motherboard for booting and a power activating signal to the motherboard. The status control unit is electrically connected to the motherboard, power supply and remote control device. The status control unit receives the manual trigger signal from the remote control device and transmits to the motherboard. The status control unit also detects absence of the power activating signal output from the power supply and stops sending the manual trigger signal.

  • Publication number: 20110304312
    Abstract: In a power circuit for reducing standby power consumption, a power supply is defined to include a primary power system and a stationary power system. The stationary power system outputs a stationary power after obtaining an input power. A control unit controls ON/OFF of the primary power system, obtains the stationary power as the required power, and receives a PS ON/OFF signal for triggering the control unit, so that the control unit controls the primary power system to supply a primary output power. The power supply includes a switch unit having two ends connected to a power circuit for outputting the stationary power and a virtual load respectively. The PS ON/OFF signal is provided for controlling the switch unit. If the switch unit does not receive the PS ON/OFF signal, it is OFF in a standby mode to avoid unnecessary power consumption of the virtual load.

  • Patent number: 8072194
    Abstract: A boost snubber circuit structure applied in a power supply having a boost circuit and a power conversion unit, wherein the boost circuit includes a boost unit connected to a switch element, a boost control unit for generating a driving signal to drive the switch element to control the charge/discharge of the boost unit, and a boost snubber unit for obtaining a voltage difference between a reference voltage and a detection signal and modulating the magnitude of the reference voltage or the detection signal to change the voltage difference and control the duration of outputting the driving signal. The voltage difference between the reference voltage and the detection signal determines the duration of outputting the driving signal. By controlling the voltage difference between the detection signal and the boost level, the invention prevents an occurrence of an inrush current caused by a too-large duration of generating the driving signal.

  • Patent number: 8047127
    Abstract: A ground coffee extraction apparatus has a base to which a filter cup loaded with ground coffee is assembled from below. A delivery system pumps cool water from a cool water tank into the extraction apparatus. The cool water exerts a downward force greater than a resilient force of resilient elements of the extraction apparatus to drive a sliding element and a downward pressing element downward. Consequently, an O-ring seals a gap between the downward pressing element and the filter cup while the downward force is evenly applied to the ground coffee in the filter cup, thereby sealing and compacting the ground coffee hydraulically. After coffee is extracted, the cool water is drawn back into the cool water tank so that the sliding element and the downward pressing element are moved upward to unseal the filter cup. Hence, the automatic extraction apparatus enables rapid, uniform, and standardized sealing and compacting.
