Patents by Inventor WEN-SHANG LAI

WEN-SHANG LAI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12130310
    Abstract: A power module device, comprising a main switch and a detection unit. The main switch is electrically connected between a first detection node and a second detection node. The first detection node and the second detection node are electrically connected between a plurality of power supply nodes, and are substantially two ends of the main switch. When the main switch is turned on, the main switch is configured to transmit a current flowing through the plurality of power supply nodes. The detection unit is electrically connected to the first detection node and the second detection node, and configured to detect a voltage across the two ends of the main switch to generate a detection voltage.

  • Patent number: 8581516
    Abstract: A power processing apparatus includes an input port, an output port, a power transforming module, and a power releasing module. The power transforming module is between the input port and the output port to transform power into predetermined voltage or current. The power transforming module has a capacitor unit connected to LEDs in parallel. The power releasing module has a switch unit to disconnect the resistor unit and the capacitor unit when the power transforming module receives the power, and to connect the resistor unit to the capacitor unit when the power transforming module does not receive the power. Therefore, it may release the residual power to make the LED off in a short time when one turns off the power.
