  • Patent number: 9146592
    Abstract: A magnet fixing structure includes a bottom wall, stopping units, a top wall and an elastic arm. The stopping units are connected to the bottom wall. The top wall is connected to the stopping units. A containing space is formed between the bottom and top walls. The elastic arm disposed on the bottom wall has a protrusion. A passage connected to the containing space is formed between the elastic arm and one stopping unit. When a magnet resists elastic force of the elastic arm to pass the passage along a first axis and partially move into the containing space, parts of the stopping units stop the magnet moving along a second axis, the bottom wall and the top wall stop the magnet moving along a third axis, and the protrusion stops the magnet moving along the first axis. Besides, an electronic device having the magnet fixing structure is also provided.

    Abstract: A conflict of interest detection system is provided. A data extractor retrieves a document and extracts author, title, and date information. A co-authorship finder finds out co-author relation among documents. A relevant group cluster identifies a key researcher in a particular field, and groups researchers connected to the key researcher as a group. A potential link finder identifies researchers who may have co-author relation. A relation filter filters out couples having weaker relation from the group having co-author relation.
