  • Text block recognition based on discrete character recognition and text information connectivity
    Patent number: 11514699
    Abstract: In an approach for a text block recognition in a document, a processor detects characters in the document using an object detection technique. A processor identifies positions of the detected characters in the document. A processor analyzes semantic connectivity among the detected characters based on the positions and semantic connectivity of the characters. A processor recognizes text blocks of related characters based on the semantic connectivity analysis. A processor outputs the text blocks associated with the related characters.

  • Fan with vibration notification
    Patent number: 7866941
    Abstract: A fan comprises a ventilation device and a vibration device. The ventilation device comprises a housing, an impeller disposed in the housing and rotating with respect to a rotating center, and a driving mechanism disposed in the housing and connected to the impeller to rotate the impeller. The vibration device is disposed on the impeller and comprises at least one fixed element, at least one movable element, and at least one track. The fixed element is fixed to the track, and the movable element is slidably disposed on the track. When the movable element slides on the track, a vibration notification is generated.
