20130127250 | POWER REDUNDANT SYSTEM - A power redundant system is provided. The power redundant system includes N first voltage generators, M second voltage generators, a switch unit and a control unit. A voltage of the i-th first voltage generator and a voltage of the j-th second voltage generator are equal. When a power good signal is enabled, the control unit enables a power control signal to control the switch unit so that an output of the switch unit is connected to an output of the j-th second voltage generator. When a power supply signal is enabled and the power good signal is disabled, the control unit disables the power control signal to control the switch unit so that the output of the switch unit is connected to an output of the i-th first voltage generator. Therefore, the first voltage generator and the second voltage generator of the system can backup each other. | 05-23-2013 |
20130127517 | DEBOUNCE APPARATUS AND METHOD THEREOF - A debounce apparatus and a method thereof are provided, which includes a debounce module, a register and a timer. The debounce module receives an input signal and eliminates a bounce phenomenon of the input signal within a transient-time of the state-changing of the input signal to produce a debounce signal. The register outputs an output signal according to the value stored in the register. When the input signal changes its state, the timer starts time-counting according to a counting-value of settling-time; when the debounce signal changes its state, the timer recounts time; and when time-counting is ended and when the value corresponding to the debounce signal is different from the register's value, the register's value is updated by the value corresponding to the debounce signal. In this way, the apparatus can eliminate the system misjudgement problem caused by occurred voltage level errors in the stable state. | 05-23-2013 |
20130130609 | FAN CONTROL SYSTEM AND METHOD THEREOF - A fan control system and a method thereof are provided. The fan control system is suited for a plurality of racks placed in an accommodation space. The fan control system includes a plurality of fan units and a fan control device. Each of the fan units is respectively disposed on each of the racks, and the fan units are arranged according to at least one air flow direction. The fan control device drives the fan units according to a driving sequence. In other words, the fan control device circularly and sequentially drives the fan units according to an order of the fan units. Thus, the fan control system maintains movement of air flow without driving all the fan units at the same time, so that the racks placed in the accommodation space are cooled efficiently and the required electric power is reduced. | 05-23-2013 |
20130132741 | POWER SUPPLY APPARATUS OF COMPUTER SYSTEM AND METHOD FOR CONTROLLING POWER SEQUENCE THEREOF - A power supply apparatus of a computer system and a method for controlling a power sequence thereof are provided. The power supply apparatus includes a power sequence module, a voltage supply unit, and a state recording module. The power sequence module provides voltage enable signals in turn according to first power-good signals. The voltage supply unit provides power voltages in turn according to the voltage enable signals and returns second power-good signals. Components in the computer system also provide third power-good signals when the components receive the power voltages. When one of the third power-good signals is converted from enabled to disabled, the state recording module delays a tolerance period according to the component corresponding to the third power-good signal, and converts the first power-good signal corresponding to the third power-good signal from enabled to disabled after the tolerance period is delayed. | 05-23-2013 |
20130154798 | ELECTRONIC DEVICE AND DISPLAY METHOD - An electronic device and a display method are provided. The electronic device includes a light emitting unit, an input switch, a power control unit, a register data storage unit and a signal control module. The input switch is configured to produce a switch signal and an address signal. The power control unit is configured to transmit power status data. The register data storage unit is configured to provide corresponding register data according to the address signal. The signal control module is electrically coupled to the light emitting unit, the power control unit, the register data storage unit and the input switch, and is configured to selectively receive the register data from the register data storage unit or the power status data from the power control unit according to the switch signal, and transmit the selected data to the light emitting unit. | 06-20-2013 |
20140142764 | FAN ROTATIONAL SPEED CONTROL SYSTEM AND METHOD FOR CONTROLLING ROTATIONAL SPEED OF FAN - A fan rotational speed control system is operable to control at least a fan and includes a baseboard management controller (BMC), a complex programmable logic device (CPLD), and a switching circuit. The BMC is operable to output a fan pulse wave signal and a Heart bit. The CPLD is operable to receive the Heart bit and determine whether the BMC is abnormal based on the Heart bit. The CPLD is operable to generate and output a switching signal and a take-over pulse wave signal when the BMC is abnormal. The switching circuit is operable to receive and output the fan pulse wave signal when the BMC is normal, and the switching circuit is operable to receive the switching signal and the take-over pulse wave signal to output the take-over pulse wave signal when the BMC is abnormal. | 05-22-2014 |
20140143597 | COMPUTER SYSTEM AND OPERATING METHOD THEREOF - A computer system and an operating method thereof are disclosed herein. The computer system includes at least one monitored device and a logic control device. The logic control device is connected to the monitored device, and is configured to monitor status signals from the monitored device so as to determine whether the monitored device is in an error state. When the monitored device is in the error state, the logic control device monitors a predetermined time period, and determines whether the monitored device recovers to normal after the predetermined time period, and determines whether the monitored device has been reset during the predetermined time period. If the monitored device does not recover to normal and the monitored device has not been reset during the predetermined time period, then the logic control device resets the monitored device. | 05-22-2014 |
20150089252 | COMPUTER SYSTEM AND OPERATING METHOD THEREOF - A computer system and an operating method thereof are disclosed herein. The operating method includes determining an operating state of a logic device; receiving a present power level of a mainboard; comparing the present power level of the mainboard with a present power level threshold of the mainboard, and determining whether to generate an alert signal accordingly; selectively providing the alert signal to a system controller or a baseboard management controller (BMC) according to the operating state; and adjusting, through one of the system controller and the BMC, whichever receives the alert signal, the present power level threshold of the mainboard. | 03-26-2015 |
