  • Publication number: 20220313896
    Abstract: The present invention discloses a device for removing sputum scabs of a respiratory tract, comprising an outer housing. A fluid hole is designed on a removing part at the front end of the outer housing, and the fluid hole is respectively communicated with a liquid pump and an air pump, so that the device can be extended into the lower respiratory tract of the patient during use. Then, the sputum scabs attached to the inner wall of the respiratory tract can be softened and removed by alternately spraying liquid and gas from the fluid hole, and the removed sputum scabs can be sucked out through negative pressure holes, so as to prevent the scabs of the secretions of the lower respiratory tract from blocking the tracheae.

  • Patent number: 10773803
    Abstract: An automatic degradable sphere distributing device for an unmanned aerial vehicle, relating to the technical field of plant protection mechanism. Said distributing device comprises a ranking portion, an adjustment portion and a distributing portion. The ranking portion consists of a rotating shaft (2), blades (1a, 1b), a rolling bearing (12), a sphere cabinet (3), a coupling (9b), a motor support (11b) and a motor (10b). The adjustment portion consists of a housing (501), a bevel gear transmission group (502, 503) and adjustment sheets (504a, 504b, 504c). The distributing portion consists of circular wheels (8a, 8b), a spur gear group (6a, 6b), a guide rod (13), a coupling (9a), a motor support (11a) and a motor (10a). Said distributing device may rank the degradable spheres vertically in sequence, being adaptable to spheres of different volumes, being highly universal, and being capable of distributing the spheres at intervals, with high precision and automation degree.

  • Patent number: 7359851
    Abstract: A method and system identifying the language of a textual passage is disclosed. The method and system includes parsing the textual passage into n-grams and assigning an initial weight to each n-gram, and adjusting the weight initially assigned to a word or n-gram parsed from the textual passage. The initially assigned weight is adjusted in a manner proportionate to the inverse of the number of languages within which such words or n-grams appear. Reducing the weight assigned to such words or n-grams diminishes—without completely eliminating—their importance in comparison to other words or n-grams parsed from the same textual passage when determining the language of a passage. The method and system of the present invention appropriately weighs the short words or n-grams common to multiple languages without affecting the short words or n-grams that are uncommon to several languages.
