20120293155 | MULTI-CHANNEL POWER SUPPLY AND CURRENT BALANCING CONTROL METHOD THEREOF - The multi-channel power supply comprises a first channel, a second channel, a current sensing module, a current average control circuit, and a modulator. The first channel and the second channel respectively transform an input voltage into an output voltage according to a first pulse width modulation (PWM) signal and a second PWM signal. The current sensing module respectively sense a first channel current and a second channel current to output a first sensing current and a second sensing current. The current average control circuit generates a first error current and a second error current according to the first sensing current and the second sensing current and an average current thereof. The modulator generates the first PWM signal and the second PWM signal according to the first error current, the second error current and the output voltage. | 11-22-2012 |
20130234755 | IMPEDANCE CALIBRATION DEVICE AND METHOD - An impedance calibration device includes: a variable impedance, an operational unit, an analog-digital converter, and a controller. The operational unit receives a first analog signal and a second analog signal, and performs a difference operation to generate an output voltage. The analog-digital converter generates an adjustment code according to the output voltage. The controller is coupled to the analog-digital converter and the variable impedance, and adjusts a resistance value of the variable impedance according to the adjustment code. | 09-12-2013 |

20140293519 | ELECTRONIC DEVICE - An electronic device is provided, including a main body, a display module, a rotary member, a slider, a first hinge, and a second hinge. The display module has a recess and a first surface. The main body, the display module, and the rotary member are pivotally connected by the first hinge. The rotary member and the slider are pivotally connected by the second hinge. When the display module is in a closed position relative to the main body, the slider is accommodated in the recess. When the display module rotates relative to the main body from the closed position to an open position, the display module pushes the slider to rotate relative to the rotary member, and the rotary member rotates relative to the display module, such that the slider protrudes from the first surface. | 10-02-2014 |
