Abstract: A display apparatus includes a communication interface configured to communicate with another display apparatus, a display configured to display contents being shared with the other display apparatus and a video call user interface (UI) for a video call with a user of the other display apparatus, and a processor, in response to at least one of a gesture and a voice of the user included in video call data received from the other display apparatus satisfying a predetermined condition, configured to control the display to change a size of the video call UI displayed on the display.

Abstract: A method for manufacturing a LiDAR device is proposed. The method may include providing a LiDAR module including a laser emitting module and a laser detecting module to a target region. The method may also include adjusting, on the basis of first detecting data obtained from the laser detecting module, a relative position of a detecting optic module with respect to the laser detecting module. The method may further include adjusting, on the basis of image data obtained from at least one image sensor, a relative position of an emitting optic module with respect to the laser emitting module.

Abstract: A strain sensor may have a conductive elastic yarn including a first fiber having a predetermined length and a shape of a fiber yarn and a second fiber having electrical conductivity and a sheet shape. The strain sensor may have a pair of wiring members electrically connected to both ends of the conductive elastic yarn. The conductive elastic yarn, with the second fiber wrapped around the first fiber, is twisted in a coil shape.

Abstract: Provided is a burner for regenerating a diesel engine particulate filter. The burner includes: a combustion chamber for receiving exhaust gas from a diesel engine; a carburetor for gasifying liquid fuel; a mixed gas supplying unit for mixing the gasified fuel with an external air, and supplying the mixed gaseous fuel to the combustion chamber; a mixed gas storing chamber disposed in the combustion chamber for receiving the mixed gaseous fuel and instantly storing the received mixed gaseous fuel; an inner flame combustor made of porous material for injecting the mixed gaseous fuel toward the inside of the inner flame combustor, and disposed in the combustion chamber to allow an exhaust gas to flow through the inner flame combustor; an igniter for igniting the mixed gaseous fuel; and a flame sensor for sensing the flame on the inner flame combustor.

Abstract: A sector data decoding circuit of a CD-ROM drive including an external memory has an input data processing unit which rearranges data received from a frame decoder of the CD-ROM drive into a CD-ROM sector data format. The rearranged data is stored in the external memory, Q and P signals are generated as is an error correcting interval signal. An L-plane error correcting unit and an R-plane error correcting unit are provided for respectively performing error correction on the L-plane and R-plane data within the one sector data stored in the external memory. A host data transmitting unit transmits the data stored in the external memory after being error corrected, to a host computer. Thus, the error correcting process separately performs error correction in parallel to shorten a period of receiving the data, thereby affording much more time in transmitting the data.

Abstract: The present invention relates to an adaptive transform acoustic coding circuit capable of ensuring the reliability of decoded audio data. The adaptive transform acoustic coding circuit is employed in a mini disc system, and includes a demultiplexer for inputting and demultiplexing a bit stream of an audio signal applied to the mini disk system; a word reconstruction unit for receiving the output of the demultiplexer, extracting and compressing audio spectrum data; a synthesis unit for extending data compressed at a word reconstruction unit for each of low, middle and high bands of the audio spectrum data and synthesizing the extended data; and an error removing unit for receiving a portion of the output of the demultiplexer and providing error removing data to the word reconstruction unit and the synthesis unit.
