This invention discloses a method and a device for calibrating channel quality instructions and dispacthing user data, the principle is that when a base station down high speed packet accesses the dispatched user data, it calibrates the channel quality instruction fed back by the user device then determines the transmission format of the data corresponding to the calibrated channel quality instruction and finally dispatches the user data to transmit them based on said determined transmission format, which carries out adaptive calibration to the channel quality instructions fed back by a user device to guarantee that the initial transmission BER, the statistic BER or residual BER will get the designed target value so as to fully utilize the gain brought with the adaptive modulation code and mixed automatic re-transmission requirement technology accessed by the down high speed packet.

The invention is applicable to the field of multimedia communication, and provides a method and a system for smoothly processing transmission stream and front-end equipment of a digital television. The system comprises a storage unit, a buffer unit, an access control unit and an output control unit, wherein the storage unit is used for receiving a first write instruction, receiving the transmission stream to be smoothly processed according to the first write instruction, receiving a read instruction, and sending the transmission stream according to the read instruction; the buffer unit is usedfor receiving a second write instruction, and receiving the transmission stream sent by the storage unit according to the second write instruction; the access control unit is used for sending the first write instruction to the storage unit according to the detected transmission stream to be smoothly processed, sending the read instruction to the storage unit according to a storage space state ofthe buffer unit, and simultaneously sending the second write instruction to the buffer unit; and the output control unit is used for selecting output transmission stream or output space packets according to the length of the transmission stream in the buffer unit. The method and the system achieve smooth processing of burst transmission stream at large code rate, and have high speed and low cost.

The invention discloses a sliding time window based WLAN (Wireless Local Area Network) indoor WKNN (Weighted K Nearest Neighbors) tracking method, relating to the field of mode identification and solving the problem of unsmooth estimated track, i.e. fierce shake of an estimated position coordinate, caused by elements of limited terminal sampling rate and difficult motion state obtain in the traditional WLAN indoor tracking method. The method comprises the steps of: firstly, acquiring signal samples and establishing a corresponding position fingerprint database; obtaining the pre-estimated position coordinate, motion rate and confidence region at different time of the terminal in real time with a WKNN positioning method according to a signal sample newly acquired; rejecting fault pre-estimated position points with abrupt signal intensity change in a pre-estimated position set compared with adjacent time position points according to a forward sliding time window threshold, a backward sliding time window threshold and a corresponding confidence region; and finally, connecting final estimated position points in chronological sequence to obtain the smooth estimated motion track for the terminal. The invention is suitable for indoor tracking and positioning.

A flow profile (2) for a vehicle, the flow profile (2) comprising at least one planar skin section (4) and at least one active flow control device (18), wherein the at least one The flat skin section (4) has an outer side (8), an inner side (16) and at least one opening (10) penetrating the skin section, the at least one active flow control device (18) being designed Into used to control the air volume. The at least one active flow control device (18) comprises an air discharge section (21) fluidly connected to the at least one opening (10), wherein the air discharge section (21) and the at least one planar The skin section (4) is produced by means of a layer manufacturing process in the form of a one-piece part without joints, and the air outlet section at least partially supports the skin section (4) in a load-bearing manner.

The present invention provides a method and device for removing an image finger based on a fixed area. The method includes: collecting a Rect area image of a predetermined area in an image; splitting the Rect area image into an upper Rect area sub-image and a lower Rect area sub-image; The image of the upper edge area of ​​the sub-image of the Rect area is the original image, and the sub-image of the upper Rect area is filled; the image of the lower edge area of ​​the sub-image of the Rect area below is the original image, and the sub-image of the lower Rect area is filled; the sub-image of the upper Rect area and The junction of the sub-images in the lower Rect area. First, the position of the finger is limited by frame selection, and then the range of the frame selection is projected and filled, and the color penetration is carried out at the splicing of the upper and lower projections, so as to achieve smooth processing at the splicing. With the above solution, no matter what kind of environment we collect images and not subject to the pressing of a finger with a fixed skin color, we can realize the mapping and filling in the frame selection area, and realize the versatility and accuracy of finger removal.
