A serial system and method for blowing antifuses are disclosed. One embodiment of antifuse system includes a plurality of latch devices connected in series from input to output. The system also includes a plurality of antifuses. The antifuses are configured to receive an output signal from a corresponding one of the latch devices. The plurality of latch devices includes a plurality of D flip-flops connected in series. Each of the D flip-flops is configured to receive an output signal from an immediately previous D flip-flop in the serial data flow and to provide an output signal to an immediately subsequent D flip-flop in the flow. In addition, the serial system provides self-detective antifuses, thus creating reliable electrical paths while saving antifuse blowing current resources and time.

An electronic system includes a serial system bus interface having a root complex and an end point, a command bus and a data bus coupled to the serial system bus interface, a memory device coupled to the data bus, and a direct memory access (DMA) controller coupled to both the command bus and the data bus to directly access the memory device in response to request commands which are transmitted from the root complex to the end point. The DMA controller includes a command queue in which the request commands stand by.

The invention relates to organic catalytic reaction, in particular to a reactor for synthesizing MTBE. The reactor is characterized in that an etherification reactor is of split structure with not less than 3 etherification reaction sections. The split structure refers to that each etherification reaction section is provided with respectively independent pot bodies filled with catalyst therein, both ends of each pot body are provided with a feed inlet and a feed outlet and other auxiliary pipeline interfaces; a raw material inlet pipeline is connected with the feed inlets of the pot bodies respectively through valves, and a product outlet pipeline is connected with the feed outlets of the pot bodies respectively through valves; the feed outlet of the pot body of each etherification reaction section is connected with the feed inlet of another pot body via a pipeline through valves, and different pot bodies are connected in series sequentially to compose a continuous annular serial system; the inlet of a heat exchanger is connected with the feed outlet of the pot body of each etherification reaction section by a pipeline through valves, and the outlet of the heat exchanger is connected with the feed inlet of the pot body of each etherification reaction section by a pipeline through valves. The invention can improve production efficiency and reduce production cost.

The invention discloses a reactive coordination control method for a direct current converter alternating current filter and a phase modifier. The reactive coordination control method comprises the steps of reserving enough dynamic reactive power storage for operating points of the phase modifier in a steady-state condition of a direct current converter alternating current voltage; for ensuring the dynamic reactive power storage of the phase modifier while a condition of switching of the alternating current filter is needed, controlling the phase modifier to act in advance, controlling the reactive power increasing or decreasing direction to be opposite to the reactive power changing direction caused by switching of the alternating current filter, so as to reduce alternating current voltage fluctuation caused by switching of the alternating current filter; and under the condition of the direct current converter alternating current voltage fluctuation, if the extremity of the phase modifier is reached while the alternating current voltage still cannot be regulated to a preset value, performing rapid switching of the alternating current filter for ensuring stability of the alternating current voltage. By virtue of the reactive coordination control method, the technical problem of not high coordination degree between the phase modifier and the direct current converter reactive compensation equipment in the prior art is solved, and the stability of an alternating current and direct current parallel serial system can be reinforced.

The invention discloses a parallel-serial capillary tube varying system inherent frequency vehicle shock absorber running method. A capillary tube parallel damping association segment and a capillary tube serial system inherent frequency association segment are sequentially connected to a pipeline between an upper oil bin oil conveying opening and a lower oil bin oil conveying opening from top to bottom; the capillary tube parallel damping association segment comprises four parallel capillary tubes, and each capillary tube is in serial connection with an electromagnetic valve and controls the electromagnetic valve to work; the capillary tube serial system inherent frequency association segment comprises four serial capillary tubes; the four capillary tubes are all in parallel connection with an electromagnetic valve and controls the valve to work. The diameter of the minimum capillary tube of the frequency adjusting segment is far larger than the diameter of the capillary tube of the resistance adjusting segment; in the matrix type work state table, according to the condition, the configuration value Smn of the electromagnetic valve in the frequency adjusting segment is selected, and through the manner of changing the mass, the problem that the inherent frequency of an automobile hydraulic shock absorber system cannot be adjusted or the adjustable range is very small is solved.
