A system and method for aircraft ground guidance and control are characterized by: inputting to a server and managing the GPS coordinate values, representing fixed location information, of all airfield lights that are installed within an airfield and can be controlled and monitored; determining whether the real-time coordinates of a moving aircraft on radars cross the fixed coordinates of the airfield lights; and specifying the location of the aircraft if the coordinates of the aircraft cross the fixed coordinates of the airfield lights, and guiding and controlling the airfield lights in the path of the aircraft. Accordingly, provided are the benefits of managing the GPS coordinate values representing fixed location information of airfield lights input to a server, accurately identifying the location of a moving aircraft if the real-time coordinates of the moving aircraft on radars cross the fixed coordinates of the airfield lights, and guiding and controlling the aircraft and airfield lights.
The present invention relates to a counterfeiting/falsification prevention means comprising a polarizing material, the counterfeiting/falsification prevention medium comprising a polarizing layer in which the polarizing material is included and on which a specific shape is printed for determining whether there is counterfeiting or falsification, wherein whether there is counterfeiting or falsification is identified by irradiating the counterfeiting/falsification prevention medium with a counterfeiting/falsification identification means capable of emitting polarized light or by using a polarizing film.

FORGERY PREVENTION MEANS INCLUDING CHOLESTERIC LIQUID CRYSTAL DISPLAY LAYER
The present invention relates to a forgery prevention means including a cholesteric liquid crystal display layer, characterized by comprising: a base layer; a design print layer laminated on the base layer and printed with a specific pattern; and a display layer laminated on the design print layer and including a cholesteric liquid crystal having a latent identification pattern that cannot be identified with the naked eye when non-polarized light is irradiated.
The present invention provides a forgery and alteration preventing means comprising a photonic crystal material complex, wherein the photonic crystal material complex is discolored according to a physical change applied to the photonic crystal material complex. The forgery and alteration preventing means including the photonic crystal material complex according to the present invention can advantageously make forgery and alteration difficult and can be simply manufactured. In addition, the forgery and alteration preventing means including the photonic crystal material complex according to the present invention advantageously enables more precise identification of forgery and alteration by changing a temperature thereof by simply pressing same by hand or by generating frictional heat.

REMOTE CONTROLLER ADOPTING A COMPLEX COMMUNICATION SYSTEM
The present invention relates to a remote controller adopting a complex communication system, comprising: a keypad (170); a Bluetooth communication module (120) which performs Bluetooth communication with AV equipment (10); an authentication information storage unit (140), in which access authentication information for enabling the Bluetooth communication module (120) to conduct Bluetooth communication with the AV equipment (10) is stored; an infrared communication module (130), which performs infrared communication with the AV equipment (10); a communication mode selecting unit (152) for inputting a communication mode selecting signal for selecting a Bluetooth communication mode or an infrared communication mode; and an MCU which controls the connection to the Bluetooth communication module (120) or to the infrared communication module (130) in accordance with the communication mode selecting signal received from the communication mode selecting unit (152), and outputs data and commands inputted from the keypad (170) to the connected Bluetooth communication module (120) or to the infrared communication module (130) in accordance with the communication mode selecting signal. According to the present invention, a communication system that corresponds to the communication system adopted by the AV equipment can be selected, by means of a single remote controller, for the AV equipment which adopts the communication system different from that of the remote controller.
The present invention relates to a multi-remote controller combined with a key board and comprises: a keyboard (120) having a front surface (120a) on which a plurality of keys for inputting characters, numbers, special characters and functions into a bidirectional IPTV, are arranged; and a remote controller (110) which is provided above the front surface (120a) of the keyboard (120) to open and close about front surface (120a) of keyboard (120), and to operate the bidirectional IPTV. In accordance with the configuration described above, the present invention can conveniently use various contents (for example SMS, MMS, chatting, surfing, online game, e-mail and the like) provided from IPTV, by simple installation of a keyboard for inputting data about the rear surface of a remote controller.
