Abstract: Disclosed is a helmet provided with a radar reflector. The helmet includes a helmet body formed in a shape corresponding to a shape of a user head, and the radar reflector mounted on an outer surface of the helmet body to reflect a radar signal transmitted from radar equipment. The radar reflector includes a plurality of reflection units each concaved in a trigonal pyramid shape having one opened surface, each of the plurality of reflection units reflecting the radar signal. Thus, by applying the radar reflector to the helmet of a user aboard an object to be detected by using a radar signal, the radar signal is effectively reflected in bad weather or at night, thereby improving the recognition rate of radar equipment.

Abstract: A reflector having an information generation function, wherein information allowing a quick and clear understanding of a traffic system and the surrounding environment thereof can be generated by a combination of unit reflectors recognizable by a light detection and ranging (Lidar) or radio detecting and ranging (Radar) system, is proposed. The reflector includes a plurality of unit reflectors for representing information through code generation, wherein each of the unit reflectors represents information by reflecting light beams or radio waves therefrom or transmitting the same therethrough, whereby binary-coded information is generated using the reflector, which allows a Lidar system or a Radar system to recognize the generated information.

Abstract: A liquid crystal display having an electrode pad for compensating for differences in resistance of electrode links. A pad portion in contact with a driving circuit includes a transparent electrode pattern having a length that depends on the length of an associated electrode link that is connected between the pad portion and a corresponding signal line at a pixel area on which a plurality of liquid crystal cells are arranged. Accordingly, resistance differences that depend on the length of the electrode links are compensated for using electrode pads, thereby making signal conductors with substantially equal resistances.
