Patent number: 12292913Abstract: An automatic industry classification method comprises: determining a scope of target patents, defining a target industry tree; generating marks on the target industry tree; performing a rough classification for the target patents by using the marks; performing a fine classification for the target patents according to a result of the rough classification. The automatic industry classification method and system provided by the present invention uses a transductive learning method, so that full mining of small annotation quantity information is realized. The automatic industry classification method and system uses information of IPC, so that information dimension is enriched, and calculation amount needed in the classification is reduced. The automatic industry classification method and system further uses the hierarchical vectors generated by the abstract, the claims and the description, so that the information of word order relation is reserved, and the patent text is deeply mined.Type: GrantFiled: January 19, 2020Date of Patent: May 6, 2025Assignee: BEIJING BENYING TECHNOLOGIES CO., LTD.Inventors: Kai Cao, Weining Li, Minyue Zhang

Patent number: 9407844Abstract: A method for synchronizing a first circuit to an electro-optical sensor is disclosed. The method generally includes steps (A) to (D). Step (A) may generate with the first circuit a configuration signal that conveys a request to capture at least one frame of a plurality of periodic frames. Step (B) may receive the periodic frames at a second circuit from the electro-optical sensor. Step (C) may discard a first frame of the periodic frames where the first frame precedes the request. Step (D) may store a plurality of active pixels in a second frame of the periodic frames in a memory where the second frame follows the request. The second circuit is generally a hardware implementation.Type: GrantFiled: July 17, 2014Date of Patent: August 2, 2016Assignee: Ambarella, Inc.Inventor: Weining Li

Patent number: 8261034Abstract: A method for moving data in a memory system of a cascading region-based filter is disclosed. The method generally includes steps (A) to (C). Step (A) may load a first portion of the data from a buffer to the memory system at a start of a given cycle using a control circuit. The memory system generally has multiple first memories. A first region of a particular first memory may receive the first portion of data. Step (B) may copy the data in a second region of the particular first memory to a third region of the particular first memory at an end of the given cycle. Step (C) may copy the data in an output region of the particular first memory to an input region of a next first memory at the end of the given cycle. The output region generally overlaps both the first region and the second region.Type: GrantFiled: December 15, 2009Date of Patent: September 4, 2012Assignee: Ambarella, Inc.Inventor: Weining Li
