The present invention relates to a ventilating and blanking device for a coal storage Eurosilo. The ventilating and blanking device includes a top blanking pipe, an axial flow fan and a baffle door, the top blanking pipe including a first pipeline and a second pipeline, an air supply pipe is connected to a side wall of the second pipeline, and the baffle door is connected to a driving mechanism; during blanking, the driving mechanism drives the baffle door so as to make the baffle door close the air supply pipe and the axial flow fan is shut off; and during ventilation, the driving mechanism drives the baffle door so as to make the baffle door close the first pipeline, and the axial flow fan is turned on. Compared with the prior art, the present invention has the advantages of ventilation efficiency, good ventilation effect, etc.

A synchronous rectifier includes a primary rectifier circuit and a secondary rectifier circuit. The primary rectifier circuit is configured to produce first and second half-rectified signals from respective first and second primary voltage outputs of a first transformer winding. The secondary rectifier circuit is configured to rectify a voltage output of a second transformer winding in response to first and second transistor gate inputs. A first buffer driver is configured to receive the first half-rectified signal and to provide a first buffered control signal to the first transistor gate input. A second buffer driver is configured to receive the second half-rectified signal and to provide a second buffered control signal to the first transistor gate input.

A method for detecting motion in video fields of video data, comprises the steps of: calculating texture information for a pixel in the video fields; determining a threshold value as a function of the calculated texture information; calculating a differential value for the pixel; and detecting motion in the video fields as a function of the determined threshold value and the calculated differential value.

Motion detection in video fields

A method for detecting edges in a video field, comprising the steps of: selecting edges for a pixel of the video field; determining sum of absolute differences ('SAD') values for the selected edges; determining inverse SAD ('ISAD') values for the selected edges; and detecting one or more certain ones of the selected edges as a valid edge as a function of the determined SAD values and the determined ISAD values.
