Abstract: A system and a method for automobile noise suppression in an automobile are provided. The system comprises a processor and a noise suppression device. The noise suppression device is configured for receiving a voice signal, which includes a speech signal and a noise signal. The processor is configured for determining an adjusting parameter set according to an automobile speed signal corresponding to a speed of the automobile. The noise suppression device can suppress the noise signal according to the adjusting parameter set, whereby enhancing the voice quality.

Abstract: A folding structure of a flier in which the nose of the fuselage is many times folded and has heavier weight. After the nose, the wing section and the folding section of the fuselage are folded, both the nose and the wing section partially overlap the folding section, whereby the folding section and the wing section can be stretched to form a flow-guiding space. In flight, the flow-guiding space makes the air blow onto the bottom face of the wing section, whereby the fuselage has a better buoyant force and the flier can stay in the air longer.

Abstract: A flier structure including a fuselage extending from front side to rear side and a weight body connected with front end of the fuselage. A port wing and a starboard wing respectively leftward and rightward extend from the fuselage. A left tailfin and a right tailfin respectively extend from rear sides of the port wing and starboard wing. The bottoms of front edges of the port wing and starboard wing are respectively connected with a left and a right flow deflecting wings. The rear sides of the left and right flow deflecting wings are respectively spaced from the port wing and starboard wing by a predetermined distance. The left and right flow deflecting wings are respectively connected with the left and right sides of the fuselage. The disconnected portions between the left flow deflecting wing and port wing and the right flow deflecting wing and starboard wing respectively form two flow deflecting spaces.

Abstract: A nail magazine structure of a power nailer, including a nail magazine formed with multiple parallel nail head channels on inner face, an intermediate board fixed at a front end of the nail magazine, and a cover board mated with the nail magazine and formed with multiple nail head channels on inner face corresponding to the nail head channels of the nail magazine. A pushing plate is disposed between the nail magazine and the cover board for pushing the T-shaped nails. A preset length of rail is disposed along a rear section of a bottom end of the nail magazine for the cover board to slide back and forth, while a front section of the bottom end of the nail magazine is railfree and connected with the intermediate board, permitting the tips of the nails to protrude out of the nail magazine. The nail heads of different specifications of T-shaped nails are optionally positioned in different nail head channels so as to locate the tips of the nails at a higher or a lower position in the nail magazine.
