Provided is a method for controlling a mask apparatus. The method for controlling the mask apparatus includes measuring a current pressure value with respect to a mask by using a pressure sensor, comparing each of a preset atmospheric pressure maximum estimation and a preset and a preset atmospheric pressure minimum estimation to the current pressure value; updating the atmospheric pressure maximum estimation and the atmospheric pressure minimum estimation according to the comparison result, and controlling a voice output of a speaker based on a difference between the updated atmospheric pressure maximum estimation and the updated atmospheric pressure minimum estimation.

Mask apparatus and method for controlling the same

Provided is a mask apparatus. The mask apparatus includes a mask body in which a microphone and a speaker are installed, a face guard coupled to a rear surface of the rear body so as to be in close contact with a user's face and having a breathing space therein, a pressure sensor installed in the mask body to measure a pressure of the breathing space, and a controller configured to compare a current pressure value measured by the pressure sensor to a reference pressure value and control a voice output of the speaker based on a difference between the current pressure value and the reference pressure value.

The present specification relates to a wireless power receiving device, receiving method, and receiving system, the device comprising individual rectifiers for each receiving coil, wherein the individual rectifiers comprise isolators for isolating a receiving coil for PC0 from a receiving coil for PC1.

Low power- and medium power-compatible wireless charging receiving device and method

Disclosed is a method for controlling a command input device. The method includes: sensing contact between a home appliance and the command input device; based on sensing the contact between the home appliance and the command input device, determining the home appliance as a target home appliance to be controlled by the command input device; and based on the determination of the home appliance as the target home appliance to be controlled by the command input device, activating a remote controller provided by the command input device and configured to control the target home appliance.

Command input device and controlling method thereof

Provided are a wireless charging apparatus in which multiple coils overlaps with one another on separated cores, and a wireless charging system including such wireless charging apparatus. According to an embodiment of the present disclosure, the wireless charging apparatus includes a plurality of plate coils spaced apart from one another, a first coil disposed on the plurality plate coils, and a second coil disposed on the first coil to partially overlap with the first coil.

Wireless charging apparatus using multiple coils and wireless charging system comprising the same

The present disclosure provides a wireless charging device in which multiple coils are overlapped with one another on separated cores. According to an embodiment of the present disclosure, the wireless charging device includes two flat cores spaced apart from each other, and a first layer coil to a fourth layer coil disposed above the two plate cores and disposed on different layers from one another and overlapped with one another, so that the multiple cores are overlapped with one another on the separated cores.

Wireless charging device using multi-coil

The present invention relates to a rolly keyboard. The rolly keyboard comprises: a body having a polygonal columnar shape; a scroll wheel formed in the body; a key assembly coupled to the body, wherein the key assembly comprises a plurality of key line portions in which the keys are disposed in each of a plurality of lines, wherein the plurality of key line portions are wound in the polygonal columnar shape of the body. Thus, scrolling can be accomplished by the scroll wheel.

Rolly keyboard

Disclosed herein is a wireless power transmitting device that includes a charging module which is configured to transmit a foreign object sensing signal for sensing at least one of a wireless power receiving device and a foreign object on a charging pad, and which is configured to transmit a wireless power signal for charging the wireless power receiving device, and a control module which is configured to control the charging module such that the wireless power signal and the foreign object sensing signal are transmitted, and which is configured to sense at least one of the foreign object and the wireless power receiving device, based on an output voltage sensed by the charging module, after the foreign object sensing signal is transmitted.

Wireless power transmitting device

Disclosed is a washing machine comprising: a tub which accommodates washing water; a drum which is disposed inside the tub, accommodates cloth, and is rotatable; a transmission coil which is disposed in the tub and supplies power wirelessly; a reception coil which is disposed in the drum and receives the power transmitted from the transmission coil; and a washing force reinforcing unit which is disposed in the drum, operated by the power delivered from the reception coil, and provides washing force to the cloth.

Washing machine

An apparatus is provided in which electromagnetic field components generated by a transmitting coil is induced to other transmitting coils based on plurality of transmitting coils being driven for multiple wireless charging, for example, wirelessly charging two or more receivers to prevent degradation in performance of detecting a receiving coil and a foreign object during multiple wireless charging.
