Abstract: A conversion control circuit is configured to generate a PWM (pulse width modulation) signal to control a power switch for switching an inductor to convert an input voltage to an output voltage. The steps of generating the PWM signal includes: enabling the PWM signal at a rising edge of a clock signal to turn on the power switch; disabling the PWM signal to turn off the power switch when an on-time exceeds a predetermined minimum on-time and the output voltage has reached an output level; triggering a next rising edge of the clock signal when the off-time exceeds a predetermined minimum off-time, the output voltage has not reached the output level, and a present cycle period of the clock signal has reached a predetermined cycle period.

Abstract: A fingerprint identification device and a fingerprint identification method are provided. The fingerprint identification device includes a self-emitting display panel, a fingerprint sensor and a processor. The self-emitting display panel displays at least one light pattern in a sensing region. The fingerprint sensor senses a finger object located above the sensing region of the self-emitting display panel to generate a first fingerprint image and a second fingerprint image corresponding to the at least one light pattern. The processor is coupled to the fingerprint sensor. The processor determines whether the first fingerprint image and the second fingerprint image have opposite tones to identify the finger object is a real finger or a fake finger.

Abstract: Cost-based license management methods for use in a license management system that manages licenses and respective costs of using license are provided. The method includes the steps of: setting a peak-hour period according to historical using record of licenses; determining whether the peak-hour period is reached and whether a usage rate for the licenses being used in the peak-hour period is higher than a upper limit; using first rate to calculate cost of using license for all of the licenses being used when the peak-hour period has not been reached or the usage rate for the licenses in the peak-hour period is lower than the upper limit; and using second rate higher than the first rate to calculate the cost of using license for part of the licenses being used when the usage rate for the licenses in the peak-hour period is higher than the upper limit.

Abstract: License management methods for use in a license management system are provided. The license management system includes licenses and first devices, each of which obtains one of the licenses. First, a license request from a second device is received and a license grade for each of the first devices and the second device is separately calculated based on a historical record of license usage corresponding to the first devices and the second device and an algorithm in response to the license request. Then, whether to agree the second device to obtain one of the licenses is determined according to the calculated grades and the number of remaining available licenses within the licenses.
