Latest Patents

Lee’s listed patent portfolio includes 2 patents.

“Storage Method and Search Method for Mark Event on Two-Dimensional Space” describes a way to store and retrieve events associated with coordinates. The method uses a hash-derived index to locate a bucket containing a search tree, then inserts events into a linked list within that tree. For searches over a designated two-dimensional range, the index and pointers help access relevant nodes and return results efficiently.

“Method for Grouping Wireless Devices and Apparatus Thereof” groups wireless devices using information about detected access points. It first assigns a device to a clustering factory based on the detected access points, then uses their feature values to classify devices within that factory into member or noise groups. The resulting grouping information is transmitted to the wireless device.

Career Highlights

Lee’s patents address practical data-processing challenges: efficient spatial indexing and search, as well as wireless-device classification. Both inventions describe structured methods for organizing information and producing results.

Collaborations

Lee’s listed coworkers include Ying-Chieh Lei and Shih-Fang Chang. The patents are associated with the Industrial Technology Research Institute.

Conclusion

Ching-Sung Lee’s patent work reflects an emphasis on efficient information organization, spanning two-dimensional event searches and wireless-device grouping.
