Abstract: A power drive circuit includes a power conversion module, a plurality of gate drivers, a waveform processing unit, a control unit, a weighting unit, and a comparator. Each gate driver includes a drive resistance setting value. The waveform processing unit outputs a current absolute value waveform of an AC power. The weighting unit generates a trigger voltage. When the comparator determines that the current absolute value waveform is greater than the trigger voltage, the comparator outputs a slew rate control signal to each of the gate drivers. When the gate driver receives the slew rate control signal, each of the gate drivers decreases the drive resistance setting value of the gate driver.

Abstract: The disclosed embodiments provide a system for detecting abusive requests. During operation, the system generates, based on one or more primary signals, a first set of clusters of network requests spanning a first period and a second set of clusters of requests spanning a second period. Next, the system stores, in a snapshot, a signature representing primary signal values and a first distribution of secondary signals in a first cluster in the first set of clusters. The system matches primary signal values from a second cluster in the second set of clusters to the signature and calculates a divergence score representing a deviation of a second distribution of secondary signals in the second cluster from the first distribution. When the divergence score violates a threshold, the system generates output for identifying additional network requests that contain one or more primary and secondary signal values in the second cluster.

Abstract: A method of manufacturing a thermal print head structure includes the following steps. A glaze layer, a heating resistor layer, an electrode layer and a photoresist layer are sequentially coated on a substrate, in which the photoresist layer has an arc ridge portion in accordance with the formation of the glaze layer. The arc ridge portion of the photoresist layer is partially removed such that a sunken portion is formed on the arc ridge portion. The photoresist layer is fully thinned to remove a bottom of the sunken portion, so that a local position of the electrode layer is revealed. The local position of the electrode layer is etched so that the heating resistor layer is partially revealed outwardly. The photoresist layer is removed from the electrode layer. A protective layer is formed on the electrode layer, the heating resistor layer, and the substrate.
