    Abstract: A wavy micro gas chromatography column includes a silicon substrate and a bonded glass cover. A micro channel having a rectangular cross section is etched on the silicon substrate and coated with a stationary phase film. A projection figure of the micro channel on the silicon substrate includes multiple regular wavy curves. Each wavy curve is formed through alternately connecting first upper arcs with first lower arcs. Because the groove has a curving structure, the carrier gas velocity is decreased as the increase of the arc angle, resulting in an improvement of the flow uniformity at the zones between two adjacent bends but also an enlarging nonsymmetric distribution at the bends. Thus, an optimal curving structure can make the overall flow more even, and in turn achieve a better separation performance compared to the straight channel columns. Meanwhile, a wavy channel realizes a longer column length on a given area.

    Abstract: A readout circuit for an uncooled infrared focal plane array includes: a first biasing circuit for generating a detection output signal; a second biasing circuit for generating a first reference output signal; a first integration circuit; and an analog-to-digital circuit including: a ramp signal generating circuit for generating a ramp signal according to a second reference microbolometer of a third biasing circuit. In the readout circuit, subtracting and amplifying the detection output signal and the first reference output signal are provided by the integrator at an analog domain, while ratio counting is provided by an analog-to-digital converter during analog-to-digital conversion. Furthermore, a column level integrated readout channel utilizes only one reference microbolometer, and the chip level ramp signal generator also utilizes only one reference microbolometer. Therefore, a chip area is further saved, and noise sources are decreased.

    Abstract: A pipelined processor including a combinational logic of several stages, a voltage regulator, a counter, a comparator, and a plurality of stage registers. Each stage register is disposed between two adjacent stages of the combinational logic. The stage register includes a flip-flop, a latch, an XOR gate, and a MUX module. When the high level of a register clock is coming, the flip-flop latches first data at the rising edge, and the latch receives second data during the high level. The data latched by the flip-flop and the latch respectively are compared by the XOR gate. If they are same, the output Error of the XOR gate is low level, and the output of the flip-flop is delivered to the next stage. Otherwise, the output Error of the XOR gate is high level, and the output of the latch is delivered to the next stage.

    Abstract: The present invention provides a federated large model adaptive learning system. Based on the combination of multiobjective optimization and incremental learning, multiple optimization indexes are constructed, and adaptive mini model incremental learning is designed. A gradient scaling method of mini models is proposed for data privacy protection under federated learning, to make full use of gradient information. A correlation between the generalization ability and sampling data is revealed to propose a generalization ability evaluation function. With respect to the real problems of performance degradation and fault faced by industrial equipment during operation, multiple optimization objectives are designed in combination with the generalization ability evaluation function, and the models are updated and repaired adaptively through multiobjective evolutionary learning, to improve the usability of large models in real industrial scenarios. Finally, the adaptive accurate update of the large models and mini models is realized to improve the generalization ability of the models.

    Abstract: A power semiconductor device, including a cell region, a transition region, and a terminal region. The transition region is located between the cell region and the terminal region of the device. A first conduction type substrate, a first conduction type epitaxial layer located above the first conduction type substrate, and a first conduction type buffer layer located in the first conduction type epitaxial layer are jointly arranged at the bottoms of the cell region, the transition region, and the terminal region of the device. In a high-current application, since the cell region occupies the largest area of a chip, in a case that breakdown can occur in the cell region and the current can be discharged through the cell region. On the basis of ensuring the BV of the terminal region, a silicon layer step is formed by elevating the position of a top structure of the terminal region.
