Presented are a method and an apparatus for performing a C-TDMA operation by receiving an additional CTS frame in a wireless LAN system. Specifically, a first AP receives an MU-RTS trigger frame from a second AP. The first AP transmits a first CTS frame to the second AP, receives a second CTS frame from the second AP, and transmits a TXOP return sequence to the second AP.

A heating coil assembly and a home appliance having same are disclosed. The disclosed invention comprises a heating coil formed from a plurality of layers of conductors stacked in the vertical direction, wherein the horizontal outer shape of the heating coil is polygonal. Therefore, an increase in horizontal size of the heating coil is suppressed to increase the cross-sectional area of a pattern per turn of the heating coil, and thus an increase in the temperature of the heating coil can be effectively suppressed.

Proposed is a movable display device for outputting video and audio, the movable display device may comprise: a transceiver which transmits data to and receives data from a mobile device by wire or wirelessly; a display which includes a touch screen and outputs video data or a user interface for a control command of audio data; a speaker which outputs the audio data; and a controller, wherein the controller receives a connection partner scan initiation request from a first mobile device, initiates a connection partner scan according to the received scan initiation request, and establishes a connection to a second mobile device in a first wireless communication manner according to the connection partner scan, and the connection partner scan initiation request is triggered by the second mobile device.

Proposed are a method and device for transmitting a PPDU by accessing a non-primary channel in a wireless LAN system. Specifically, a reception STA performs backoff on a first non-primary channel. The reception STA performs channel access to a second non-primary channel when the value of the backoff on the first non-primary channel is zero. The reception STA transmits the PPDU to a transmission STA through an idle channel among the first and second non-primary channels. The first non-primary channel is a secondary 20 MHz channel on which the backoff can be performed while an NAV is set in a primary 20 MHz channel. The second non-primary channel is a secondary channel other than the first non-primary channel in a BSS operating channel.

The present invention relates to a heating coil assembly, a home appliance having same, and a manufacturing method therefor. The present invention comprises a heating coil formed by means of a plurality of vertically stacked layers of conductors, wherein the horizontal outer shape of the heating coil is polygonal. Accordingly, the increasing of the horizontal size of the heating coil is suppressed, while the pattern cross-sectional area per turn of the heating coil is increased, and thus the increasing of the temperature of the heating coil may be effectively suppressed.

The present disclosure relates to a display apparatus for a vehicle. A display apparatus for a vehicle according to an embodiment of the present disclosure includes: a picture generation device including a light output device and configured to output a projection image; an optical path separator configured to reflect a first projection image, which is a part of the projection image; a screen having one surface onto which the first projection image reflected by the optical path separator is projected; a viewing angle adjustment panel including a liquid crystal layer composed of liquid crystal molecules to allow at least part of light emitted from the screen to pass through; and a signal processing device configured to output a signal for adjusting an arrangement of the liquid crystal molecules to the viewing angle adjustment panel such that a viewing angle for one area of the screen is adjusted, wherein a second projection image, which is another part of the projection image, is projected onto a windshield. Other various embodiments are possible.

It relates to a cooking appliance in which it is possible to prevent deterioration in space utilization by forming a through hole, into which a temperature sensor can be at least partially inserted and coupled, on a coil circuit board module in which a working coil pattern is formed, while enabling the temperature sensor to be effectively installed without securing a separate installation space for the temperature sensor.

An electric range in one embodiment may comprise: a cover plate having a top surface on which an object to be heated is arranged; a supporter accommodated in a case; a plurality of coil substrates which are arranged on the top of the supporter and spaced apart from each other, and on which a working coil is printed; a first insulator arranged between the supporter and the cover plate; and a second insulator arranged between the supporter and the cover plate and positioned at the upper side and/or the lower side of the first insulator.

According to an embodiment, a display device including semiconductor light emitting devices includes a display panel and a frame connected to the display panel. The display panel includes a first display module and a second display module disposed adjacent to each other, each of the first display module and the second display module including a plurality of semiconductor light emitting devices disposed on a substrate, and a seam filling material disposed between the first display module and the second display module. The seam filling material may have a curved surface on one side thereof.

Disclosed is an invention related to a home appliance. The invention disclosed herein includes a heating coil formed by a plurality of layers of conductors stacked in the up-down direction, wherein the horizontal outline of the heating coil has a polygonal shape. Accordingly, the cross-sectional area of patterns per turn of the heating coil increases while an increase in the size of the heating coil in the horizontal direction is suppressed, and thus a rise in the temperature of the heating coil can be effectively suppressed.
