Abstract: Disclosed herein is a method and apparatus for synchronizing timeslots in a wireless LAN system. The timeslot synchronization method includes: setting, by a first node, a timeslot synchronization reference based on a time synchronization function (TSF) value, followed by transmitting information about a reference of synchronization to a second node; and setting, by the second node, a timeslot synchronization reference based on a TSF value corresponding to the reference of synchronization based on the information transmitted from the first node.

Abstract: A scanning method in a wireless local area network (WLAN) system is provided. The scanning method includes transmitting, by a station, a probe request frame and receiving, by the station, a probe response frame from an access point (AP). The AP determines whether to transmit the probe response frame in response to the probe request frame using information indicated by the probe request frame.

Abstract: Disclosed herein are a system and a method for volitional electromyography (vEMG) signal detection from an EMG signal when functional electrical stimulation (FES) is applied. The system for vEMG signal detection includes a receiver for receiving data from an EMG electrode when FES is applied, a memory for storing a program for detecting a vEMG signal using the received data, and a processor for executing the program, wherein the processor cuts the data received from the EMG electrode disposed at a predetermined position, calculates a difference between data for previous FES and data for current FES, and detects the vEMG signal using the calculated difference.
