Title: Youngjune Lee Gwon: Innovator in Location Estimation Technologies
Introduction
Youngjune Lee Gwon is a prominent inventor based in Mountain View, CA (US). He has made significant contributions to the field of location estimation technologies, holding a total of 5 patents. His innovative work focuses on enhancing the accuracy and reliability of location estimation methods.
Latest Patents
One of his latest patents is titled "Method and apparatus for location estimation using region of confidence filtering." This method employs filtering in both the radio signal domain and the space domain separately. It filters raw values of the run-time radio signal measurements to reject distorted inputs. A region of confidence (RoC) is formed according to certain algorithms, and only location estimates falling within the RoC are considered for further processing. The location estimate candidates filtered by the RoC are organized into time-indexed bins, with each bin containing candidates obtained at similar times. A shortest route connecting a candidate from each bin is calculated to further improve the accuracy of the location estimation.
Another notable patent is "Selective fusion location estimation (SELFLOC) for wireless access technologies." In an RF environment serviced by 802.11, Bluetooth™, or other network transmitters, this method utilizes redundancy to refine an estimated location of an RF receiver. The method includes receiving signals from fixed transmitters, calculating preliminary location estimates, and combining these estimates using predetermined reference information on the RF environment. The reference information includes minimum mean-squared error optimizing coefficients.
