Abstract:
PURPOSE: A magnetic field communication apparatus of an on-line electric vehicle using electromagnetic induction is provided to communicates between an inverter and an on-line electric vehicle by transmitting energy to a secondary resonance load circuit unit from a first conductive line with an electromagnetic induction. CONSTITUTION: A first electronic induction circuit unit is installed on the lower side of a vehicle which passes on a power rail. A secondary load resonance circuit unit is laid under a road. A DC voltage of an input terminal(10) is converted into an AC voltage in a primary resonance circuit unit(30) through a rectifier. The converted AC voltage is transmitted to a secondary coil of the load side resonance circuit. A photocoupler outputs a DC signal converted by the rectifier.

PURPOSE: A dielectric elastomer energy collecting device, an energy collecting method using the same, a charging circuit using the same, and a tactile sensor using the same are provided to store energy generated by the large variation of capacity and output voltage by supplying preset compressive force to an electrode with an electric field. CONSTITUTION: An electric field is formed with an input voltage. Two electrode layers(200) generate an output voltage and are separated from each other. A dielectric layer(100) is formed between two electrode layers and is made of dielectric elastomer.

PURPOSE: A view line associating device is provided so that an opaque object is not seen to an observer in a visible ray area using the principle of associating view line. CONSTITUTION: A view line associating device comprises an input module(100), an output module(200), and a connection module(300). The light radiated from subjects(10,20,30) is input to the input module in a predetermined direction. The output module receives the light input from the input module and outputs it in a predetermined direction. The connection module transfers the light input to the input module to the output module so that the light, which is radiated from the subject and is input to the input module, matches with the predetermined direction and is transferred to an observer who observes the subjects.
