  • Patent number: 11983271
    Abstract: A processor may generate an enforcement point. The enforcement point may include one or more adversarial detection models. The processor may receive user input data. The processor may analyze, at the enforcement point, the user input data. The processor may determine, from the analyzing, whether there is an adversarial attack in the user input data. The processor may generate an alert based on the determining.

  • Publication number: 20240146205
    Abstract: A flyback power converter includes a power transformer, a first lossless voltage conversion circuit, a first low-dropout linear regulator and a secondary side power supply circuit. The first low-dropout linear regulator (LDO) generates a first operation voltage as power supply for being supplied to a sub-operation circuit. The secondary side power supply circuit includes a second lossless voltage conversion circuit and a second LDO. The second LDO generates a second operation voltage. The first operation voltage and the second operation voltage are shunted to a common node. When a first lossless conversion voltage is greater than a first threshold voltage, the second LDO is enabled to generate the second operation voltage to replace the first operation voltage as power supply supplied to the sub-operation circuit; wherein the second lossless conversion voltage is lower than the first lossless switching voltage.

  • Patent number: 8552954
    Abstract: A liquid crystal display system for improving display color mismatch utilizes a pixel-charge delay circuit to generate a new latch-data signal for a source driver of the liquid crystal display system according to an output-enable signal and a latch-data signal generated by a timing control circuit of the liquid crystal display system. Therefore, when the source driver charges a pixel on an mth gate line, a switch corresponding to a pixel on an (m?1)th gate line is already completely turned off.
