Abstract: An apparatus for manufacturing a secondary battery includes: an index table configured to receive a secondary battery cell, the secondary battery cell including an electrode assembly, a can accommodating the electrode assembly, and an electrode tab between the electrode assembly and the can to electrically connect the electrode assembly to the can; a laser scanner configured to irradiate laser onto an outer surface of the can to weld the electrode tab to the can; and a controller configured to variably control the laser scanner according to an operation of the index table.

Abstract: A mounting jig for manufacturing a tiling display device can include a supporting member, a plurality of jig magnets fixed to the supporting member, a hinge structure configured to rotate the plurality of jig magnets, and a guard rail configured to rotate in response to a rotation of the plurality of jig magnets, to reduce damage caused during detachment or attachment. The tiling display device includes a plurality of display devices disposed in the form of tiles. Each of the plurality of display devices includes a plurality of display elements, a plurality of circuits, a plurality of lines and a plurality of parts. The plurality of display elements can be a light emitting diode (LED) or a micro-LED including an n-type semiconductor layer, a p-type semiconductor layer, and a light emitting layer.

Abstract: Disclosed are an apparatus for authenticating a user in a user terminal and a method thereof. The method according to the present disclosure includes a step of providing a guide for inducing a user motion, a step of emitting a radar signal and generating a reference signal based on a reflected signal generated by a user motion, a step of generating a plurality of additional signals based on the characteristic values of the reference signal, and generating a plurality of additional samples self-duplicated by combining the additional signals with the reference signal, a step of outputting a guide for inducing a user motion for user authentication upon determining that user authentication is required, a step of recognizing a user motion based on the radar signal, and a step of performing user authentication based on the recognized user motion.

Abstract: Disclosed is a radar-based human motion recognition apparatus including a first radar for emitting a first radar signal for detecting a position of an object, a second radar for emitting a second radar signal for gesture recognition, an antenna for receiving a first reflected signal reflected from the object by the first radar signal and a second reflected signal reflected from the object by the second radar signal, and a controller for determining situation information based on second signal processing for the second reflected signal.
