Some embodiments of the present disclosure provide a method for managing access points in a Wi-Fi network by using a centralized controller. In some embodiments of the present disclosure, a Wi-Fi access point management method is provided for minimizing interference between Wi-Fi access points in a Wi-Fi network environment, and for reducing excessive power consumption by using a centralized controller to adapt to network conditions, meeting requirements including users' traffic demands.

Method for managing access points in WiFi network

An authentication apparatus includes an electrocardiogram (ECG) signal receiver configured to receive a target ECG signal, and a preprocessor configured to filter the target ECG signal. The apparatus further includes an authenticator configured to process the filtered target ECG signal based on a pattern of a reference ECG signal, and determine whether the target ECG signal corresponds to the reference ECG signal based on the processing.

User authentication method and apparatus based on electrocardiogram (ECG) signal

A rectenna according to the present invention includes a circular-polarized patch antenna having dual slots fed by a microstrip and configured to receive and output a radio frequency (RF) signal, and a rectifying circuit configured to convert for output the RF signal, received by the circular-polarized patch antenna, into a direct current (DC) signal and transfer the DC signal from the antenna to a load, wherein the rectifying circuit comprises at least one radial stub.

Wideband rectenna and rectifying apparatus for rectenna

A pulsed magnet includes a cylindrical coil part having a hollow opening, and amorphous metal modules disposed along an outer circumference of the coil part and extending in a normal direction, which results in facilitation of cooling and minimization of generation of an eddy current.
