An NFC device that receive a data frame with a start pattern including first and second pattern signals, and a data pattern corresponding to the start pattern. The NFC device comprising an analog-to-digital converter which generates first and second input signals based on the first and second pattern signals, respectively, a modem that includes a first sub-matched filter which multiplies a first match signal by the first and second input signals to respectively calculate first and second result values of the first match signal and multiplies a second match signal by the first and second input signals to respectively calculate first and second result values of the second match signal. The first sub-matched filter determines reception of the start pattern when the first and second result values of the first match signal or the first and second result values of the second match signal exceed a predetermined start pattern threshold.

Provided is a dehumidifier capable of preventing condensation from flowing to the outside of a water container when the dehumidifier is turned over or while the dehumidifier is moved, since a suction structure for suctioning the condensation and a discharge structure for discharging the condensation are improved. The dehumidifier comprises: a main body having a suction port; a heat exchanger provided inside the main body and removing moisture in the air; and a water collection device for collecting the condensation generated in the heat exchanger, wherein the water collection device comprises: an auxiliary water container in which the condensation is collected; a housing for guiding the condensation to the auxiliary water container; a connection hose provided to have a bent part so as to connect the auxiliary water container and the housing; an upper water container detachably provided at the upper part of the main body so as to drain the condensation; and a pump for pumping, to the upper water container, the condensation collected in the auxiliary water container.

An apparatus for identifying a communications signal in a preceding stage for a communications modem includes a communications signal identifying unit configured to receive a communications signal through a port, deliver data included in the communications signal to a communications modem, and sample the communications signal which has passed through the port during every unit length to detect a unit length pattern corresponding to a start of communication and a unit length pattern corresponding to an end of communication. When a length from the start of communication to the end of communication is equal to or smaller than a reference length, the communications signal identifying unit delivers a data process stopping signal to the communications modem such that the communications modem stops a data reading operation.

An air conditioner having an indoor unit and an outdoor unit, at least one of which includes a communication unit, a switching unit turned on when communication lines are connected to the communication unit, turned off in a standby mode, and turned on when the standby mode is released, a voltage distribution unit distributing voltage applied to the communication unit when the switching unit is turned off, a voltage adjustment unit adjusting the voltage applied to the communication unit and transmitting the adjusted voltage to the communication unit, and a control unit turning the switching unit on when driving voltage is input to the control unit, turning the switching unit off when the at least one of the indoor unit and the outdoor unit enters the standby mode, and turning the switching unit on based on the voltage distributed by the voltage distribution unit in the standby mode.

Air conditioner

A transmitter of a NFC device includes a current detector which detects a first current flowing in an output node of a regulator and outputs a current detection signal related to a result of the detection, and a control block which compares the current detection signal with a reference current and generates a control signal for controlling a voltage of the output node according to a result of the comparison.
