    Abstract: A route guidance method and system using smart signages is disclosed. The route guidance method may include obtaining user information of a user or an object from a first smart signage detecting an access of the user, searching a database for route information about a route to a stored destination corresponding to the user information, identifying a second smart signage being separate from the first smart signage by a distance in a direction of the destination among a plurality of smart signages being on the route of the route information, and extracting, from the route information, a partial route from the first smart signage to the second smart signage and providing the extracted partial route to the first smart signage.

    Abstract: Provided is a Radio Frequency Identification (RFID) tag having a plurality of antennas. The RFID tag includes: a plurality of antennas each configured to backscatter received Radio Frequency (RF) signals; a digital and memory circuitry, which once the RF signals are received through the plurality of antennas, is configured to generate a series of programmed encoding signals based on identification information to be transmitted, and to output the generated signals; and a modulator configured to vary power of an uplink signal backscattered through the plurality of antennas based on the encoding signals input from the digital and memory circuitry, in which the modulator operates such that the power of the uplink signal backscattered through each of the plurality of antennas is equal regardless of types of the encoding signals.

    Abstract: Provided herein are a reflective lens capable of changing a focal length and an optical system using the same. An active reflective lens according to an embodiment includes: a lens unit including material that is deformable in response to an electric signal; a support unit configured to support the lens unit; a base unit formed below the support unit; a first electrode formed on the lens unit; and a second electrode formed on the base unit. The distance between the first electrode and the second electrode is determined depending on a shape of an upper surface of the base unit, and the distance between the first electrode and the second electrode varies depending on regions of the lens unit.
