Latest Patents

Choon-Sik Yim holds a patent for an "Apparatus for synchronizing clock in real-time locating system and method therefor." This highly precise clock synchronization apparatus includes an optical transmitting/receiving unit that receives a clock information frame from a clock synchronization server. It converts the received clock information frame in series-parallel and transmits/receives the clock information data and the clock information. Additionally, it features an offset estimation unit that detects a preamble signal and a clock information signal from the series-parallel converted clock information frame. This unit calculates a phase difference value by comparing the detected preamble signal with the detected clock information signal, ultimately outputting an offset value based on the calculated phase difference value. Furthermore, a clock synchronization unit updates a local clock value to match the time of the clock synchronization server based on the offset value and the clock information frame.
