Abstract:
The present invention pertains to a technique for supplying power to an object in midair, and more specifically, to a ground-level power supply system for a small unmanned aerial robot to continuously supply power as a power source for the small unmanned aerial robot to stay in midair a long time, to operate a camera, a communication relay, and a lighting device, and to hover in midair with directional change and the like. The ground-level power supply system includes: the small unmanned aerial robot including a propeller, a monitoring camera, a communication relay, a motor/controller, a voltage booster/charger, a light-emitting diode (LED) lighting device, a battery power source, and a wind direction balancing device; and a ground-level power supply for supplying power from the ground, wherein the ground-level power supply includes: a cable formed by a flexible material, wherein the thickness of inner wirings in the cable varies according to the body size or the use of the small unmanned aerial robot; a wiring winding device functioning as a reel for winding and unwinding the cable; a fixing device for fixing the cable to the wiring winding device; a fixing base installed with a weight that changes according to the size of the small unmanned aerial robot to fix and pull the small unmanned aerial robot when the fixing base is installed on the ground; an outlet formed to receive alternate current (AC) or direct current (DC) power from the outside; and a power connection line for supplying power to the small unmanned aerial robot via the cable which supplies the power by supplying the AC or DC power received from the outlet to a cable terminal of the wiring winding device.
Abstract:
The present invention relates to a platelet-type zirconium phosphate which has a P-OH group in the structure thereof, has a crystalline peak at a 2è value of 11.6±2 degrees in an X-ray diffraction analysis, and shows no crystalline peak at a 2è value of less than 11.6±2 degrees. The platelet-type zirconium phosphates prepared by the method of the present invention have a platelet structure and may be uniformly dispersed at the nanoscale in a film to exhibit excellent surface gloss and barrier capability. The platelet-type zirconium phosphates prepared by the method of the present invention have the P-OH group at the surface thereof so as to exhibit excellent corrosion resistance, and may be dispersible not only in an aqueous solution, but also in an organic solvent or the like.
Abstract:
Provided are an apparatus and method for manufacturing molten iron. The apparatus for manufacturing molten iron, according to the present invention, comprises: a multi-stage fluid bed furnace for converting fine iron ore into reduced fine iron through reduction; at least one high-temperature compacting unit for preparing a high-temperature compacted iron by compressing the reduced fine iron; at least one crushing unit for crushing the high-temperature compacted iron to have a certain particle size; a first conveying unit for conveying the crushed high-temperature compacted iron; and a melting furnace for melting the conveyed high-temperature compacted iron by combusting fine or lump coals, and for supplying a reducing gas, which is generated in the furnace, to a fluidized reduction furnace. In addition, the apparatus further comprises at least one compacted iron storing unit for storing some of the compacted iron which has been crushed. According to the present invention, molten iron can be manufactured stably and efficiently.
Abstract:
The present invention discloses an interworking system between a user terminal and a smart card for executing a widget and a method thereof. That is to say, the interworking system is configured to enable the internal management of a user terminal for the download-setup information for a widget UI program stored in a smart card. As a result, the user terminal is able to download widget UI (User Interface) data to be updated from a program-providing server based on the download setup information even if there is no additional request from the smart card. Therefore, the system is able to prevent periodic communication between the user terminal and the smart card when updating the widget UI program.
Abstract:
The present invention relates to an interface system between a smart card and a terminal for the preparation of the execution of a service application embedded in the smart card, to a method for same, and to a smart card applied to same. That is, the interface system includes a terminal and a smart card. The terminal has a plurality of device resources required for executing a service application embedded in the smart card. The smart card is embedded with a Universal Subscriber Identity Module (USIM), and receives a device resource list from the terminal and prepares, on the basis of the received device resource list, a selective execution considering a service support terminal, from among a plurality of embedded service applications. As the present invention enables selective execution in accordance with the device resources of a terminal, from among a plurality of service applications embedded in a smart card, it is possible to provide a service appropriate to the performance of a terminal in consideration of the type of the terminal and difference in performance of terminals manufactured by different manufacturers.
Abstract:
The present invention relates to a system for interfacing between a terminal and a smart card embedded with a Universal Subscriber Identity Module (USIM), to a method for same, and to a smart cad applied to same. That is, the smart card of the present invention has a configuration in which one or more service applications are embedded, executes a specific service application in accordance with a request from the terminal, and provides the terminal with a value output from the execution of the specific application to make a request for the transmission of the value to a specific input/output device. Whereby, the present invention defines a service application execution process in a smart card by using a new interface between a terminal and the smart card.
