Abstract: A switching control circuit for use in controlling a resonant flyback power converter generates a first driving signal and a second driving signal. The first driving signal is configured to turn on the first transistor to generate a first current to magnetize a transformer and charge a resonant capacitor. The transformer and charge a resonant capacitor are connected in series. The second driving signal is configured to turn on the second transistor to generate a second current to discharge the resonant capacitor. During a power-on period of the resonant flyback power converter, the second driving signal includes a plurality of short-pulses configured to turn on the second transistor for discharging the resonant capacitor. A pulse-width of the short-pulses of the second driving signal is short to an extent that the second current does not exceed a current limit threshold.

Abstract: A resonant flyback power converter includes: a first and a second transistors which form a half-bridge circuit for switching a transformer and a resonant capacitor to generate an output voltage; a current-sense device for sensing a switching current of the half-bridge circuit to generate a current-sense signal; and a switching control circuit generating a first and a second driving signals for controlling the first and the second transistors. The turn-on of the first driving signal controls the half-bridge circuit to generate a positive current to magnetize the transformer and charge the resonant capacitor. The turn-on of the second driving signal controls the half-bridge circuit to generate a negative current to discharge the resonant capacitor. The switching control circuit turns off the first transistor when the positive current exceeds a positive-over-current threshold, and/or, turns off the second transistor when the negative current exceeds a negative-over-current threshold.

Abstract: A semiconductor device is disclosed herein. The semiconductor device includes a routing structure. The routing structure has an intermediate conductive routing layer.

Abstract: An environment monitoring system includes N sensors, a server and a monitoring device, where N?3. The sensors respectively generate multiple pieces of sense data related to a monitoring area. The server determines whether at least three of the pieces of sense data are abnormal, and generates position data based on the at least three pieces of abnormal sense data when the determination is affirmative. The monitoring device includes a body that is movable in the monitoring area, an image capturing module and a control module. The control module controls the body to move to a position corresponding to the position data, and the image capturing module captures an image at said position.

Abstract: A golf club head includes a golf club head body and at least one weight-adjusting member mounted thereto. The golf club head body is provided with at least one assembling portion to combine the club weight-adjusting member. The club weight-adjusting member is made from a material selected from a mixture of macromolecular materials and metal powders such that the club weight-adjusting member functions to adjust a center of gravity of the golf club head and to absorb vibrations in striking a golf ball.
