Abstract: A user access control method for an information system is proposed. The method may include processing login of a user using the information system, and acquiring a reference image obtained by capturing the logged-in user on the basis of a login time. The method may also include extracting reference feature information from the reference image and storing the reference feature information, and acquiring target images obtained by capturing a user using the information system at predetermined intervals. The method may further include extracting each target feature information from each target image; comparing each target feature information with the reference feature information to confirm whether or not each user using the information system at predetermined intervals is the same as the logged-in user, and controlling an access for the each user using the information system when the each user using the information system is not the same as the logged-in user.

Abstract: A power transfer system includes an electric vehicle supply equipment (EVSE) for providing electric power to an electric vehicle (EV) and an electric power reception device mounted in the EV; a first conductor plate electrically connected to a primary-side circuit of the EVSE; a compensation circuit for transferring a power input signal of the EVSE to the first conductor plate; a second conductor plate disposed in the EV and connected to the electric power reception device; and a secondary-side circuit for transferring a power signal received by the second conductor plate to a load, where the electric power is transferred from the EVSE to the EV by capacitive coupling between the first conductor plate and the second conductor plate.
