  • Patent number: 9613223
    Abstract: A method for application management is provided. First, an original application is received. A license code is injected into the original application through a repackaging process to generate a repackaged application. Next, the repackaged application is published for a user device to download and install, wherein the user device executes a client program. When the user device executes the repackaged application, the license code sends a license check request to activate the client program to send a license check response according to license information of the repackaged application. The license check response indicates whether the repackaged application is allowed to be further executed. When the license check response indicates that the repackage application is not allowed to be further executed, the license code terminates the repackaged application.

  • Patent number: 6762926
    Abstract: The energy content of supercapacitor is determined by its capacitance value and working voltage. To attain a high capacitance and a high voltage, several pieces of electrodes and separators are spirally wound with edge sealing to form a bipolar supercapacitor in cylindrical, oval or square configuration. While the winding operation effectively provides a large surface area for high capacitance, the bipolar packaging instantly imparts a unitary roll a minimum working voltage of 5V on using an organic electrolyte. The bipolar roll is a powerful building block for facilitating the assembly of supercapacitor modules. Using containers with multiple compartments, as many bipolar rolls can be connected in series, in parallel or in a combination of the two connections to fabricate integrated supercapacitors with high energy density as required by applications.
