The present invention relates to a wireless charging device including a communication signal compensator, a communication signal compensator comprises a power detector configured to detect a magnitude of a communication signal received through each of the plurality of antennas, and a control unit configured to acquire a communication signal having the greatest signal magnitude as the detection result, select an antenna corresponding to the communication signal having the greatest signal magnitude among the plurality of antennas, and transmit, to the coupling antenna, a switch control signal for controlling the switch to be connected to the selected antenna.

Communication signal compensator

A communication apparatus according to an embodiment of the present invention is configured to determine a frequency band of a communication signal by analyzing a power level of the communication signal detected by a detection unit, and control a band setting unit to set the communication frequency band as the determined frequency band of the communication signal, and determine an output band of the communication signal by analyzing the communication frequency band and a waveform of the communication signal, and control a output setting unit to set a communication output band as the determined output band of the communication signal.

Communication apparatus

Disclosed is a thermally-conductive elastic body that effectively dissipates heat generated from a heat generation source such as an electronic product and prevents a phenomenon in which small graphite fragments are separated from (fall off) a graphite layer by completely sealing up the graphite layer that conducts the heat. The thermally-conductive elastic body according to the embodiments of the present disclosure includes an elastic body and a thermally conductive layer that is formed to be wrapped around an external surface of the elastic body, in which the thermally conductive layer includes a first base film and a graphite layer that is internally arranged within an edge region of the first base film, and in which the edge region of the first base film is attached to the elastic body in such a manner that the graphite layer is sealed up.

Thermally-conductive elastic body

According a method of protecting a motor-driven power steering system from overheat, it is possible to prevent a steering motor and an ECU from being broken by overheat by controlling electric current supplied to the steering motor, by calculating an engine stop time from radiation temperature maps stored in a memory and changes in temperature of a temperature sensor when the engine having been stopped restarts without operating a specific protection logic when the engine stops, and calculating temperature of the steering motor and the ECU from the radiation temperature maps and the engine stop time.
