Abstract: In order to solve the above-described problem, the present disclosure provides a system and a method for signal processing with an external smart device using an earphone port. The earphone port includes a speaker terminal and a microphone terminal and receives a signal from an earphone plug of the peripheral device connected to the smart device. The connection recognition unit recognizes a connection between the earphone plug of the peripheral device and the earphone port. The application operating unit receives an executive command of an existing signal processing application through an input module and executes the signal processing application in response to the executive command. The data processing unit performs a predetermined signal analysis on a data signal input from the peripheral device through the microphone terminal according to an operation of the executed signal processing application and outputs a result of the signal analysis through an output module.

Abstract: A skin moisture measuring apparatus that measures moisture in a testee's skin includes an earphone plug that is connected to an earphone port of a smart device and connects the skin moisture measuring apparatus to the smart device; an oscillation signal generation unit that generates an oscillation signal; and a sensor unit that includes two or more contact portions exposed to the outside to be in direct with the testee's skin, modifies the oscillation signal depending on an electrical resistance corresponding to a moisture content in the testee's skin and formed between the two or more contact portions, and generates a measurement signal. In the skin moisture measuring apparatus, the sensor unit transmits the measurement signal to the smart device through the earphone plug.

Abstract: A cooling system of an LED light employs a dehumidifying agent absorbing moisture in the air while the LED light is turned off, and dissipates heat from the LED light using heat of vaporization by vaporization of the moisture by heat from the LED light when the LED light is turned on. The system includes an LED module, a thermal sheet, a heat pipe, a heat sink, and a dehumidifying sheet. The LED module includes a PCB and multiple LEDs, and the thermal sheet is disposed on the LED module. The heat pipe of a cornered U-shape has a circular cross section and is coupled to a connector on the thermal sheet. The heat pipe has a horizontal section contacting an upper side of the thermal sheet and a vertical section protruding to the connector. The dehumidifying agent is disposed on the heat sink inserted into the heat pipe.
