  • Patent number: 9167650
    Abstract: A light source drive circuit is disclosed which uses a low withstanding voltage transistor is discussed. The light source drive circuit can enhance price competitiveness. Also, the light source drive circuit can allow a current flowing through an LED portion to be eliminated when a PWM signal is not applied. Therefore, the light source drive circuit can enhance a contrast ratio.

  • Patent number: 6260141
    Abstract: A software license control system is based on independent software registration servers. The registration servers are open to all software manufacturers. On user's computer, a software product asks the user software license control program whether the user has a usage license for the software product. The user license control program checks the license file, received from a software registration server, and answers the software product. If the answer is “no”, the software product stops running. If the answer is ‘yes’, the software product continues. The license file cannot be used by unauthorized user because the file is encrypted by the user public key and digitally signed by the secret key of a software registration server. To use a license file, user needs the secret key of the user and needs a passphrase to activate the secret key. The license file is digitally signed by the software registration server and cannot be modified by a user to add unauthorized licenses.
