Abstract: A system and method for laser assisted bonding of semiconductor die. As non-limiting examples, various aspects of this disclosure provide systems and methods that enhance or control laser irradiation of a semiconductor die, for example spatially and/or temporally, to improve bonding of the semiconductor die to a substrate.

Abstract: A method for identifying a counterpart of a messenger according to an embodiment of the present invention includes: receiving an action signal of a user from the outside by a communication unit; reading user information related to the user from a database; determining an initial message and a response message including an identification indicator for identifying the user, based on the user information by a processor; requesting a messenger server to open a conversation channel, in which the user is designated as a counterpart, to transmit the initial message and to output the response message by the communication unit; receiving the response message by the communication unit; and checking the identification indicator output in the received response message and specifying a person corresponding to the identification indicator as the counterpart by the processor.

Abstract: Disclosed is a review management system based on a chatbot. The review management system includes an information reception unit configured to receive product purchase information of a user from at least one sales server, a checking unit configured to monitor delivery information of the purchased product in real time, a chatbot execution unit configured to establish a channel through which a chatbot is able to communicate with the user when a preset period elapses after the checking unit checks delivery completion, and request the user to upload a review of a corresponding product, and a review posting unit configured to post a review on a review page when the user uploads the review on the channel. According to an embodiment of the present disclosure, it is possible to expect for an individual user to positively upload a review by providing a personalized chatbot interface to the user.

Abstract: Provided is a code processing method comprising: a code registering step of matching an RGB code and identification information so as to generate a code database; and a recognizing step of extracting at least one RGB code from the color code and recognizing identification information corresponding to the at least one RGB code by using the code database in which the identification information according to the RGB code has been stored in advance, when a color code is received from a recognition request terminal.

Abstract: An upright type cleaner that uniformly provides a suction force through the whole area of a suction port. The upright type cleaner includes a body having a fan motor that generates suction force, a suction brush provided at a lower portion of the body and having a suction port to perform a cleaning operation relative to a floor using the suction force, a rotating drum installed in the suction brush, a belt connected between the rotating drum and the fan motor, a belt cover that guides the belt and divides the suction port into two suction areas, and a connection path through which the two suction areas are communicated to each other about the belt cover.

Abstract: A vacuum cleaner has a discharge flow path and a discharged-air filter optimally positioned to reduce noise. The vacuum cleaner includes a body, a dust collection unit positioned in the body to filter foreign matter, a blower fan unit including a blower fan and a motor to generate suction force, an air vent through which air drawn into the body is discharged, and a discharge flow path to guide the air discharged through a discharge port of the blower fan unit to the air vent. The discharge flow path comprises a space defined between the dust collection unit and the blower fan unit.

Abstract: A vacuum cleaner having a discharge flow path, which reduces noise generated due to resistance of the flow path, and by a motor. The vacuum cleaner includes a body, a blower fan unit including a blower fan and a motor to generate suction force in the body, an inner case surrounding the blower fan unit and having an inner flow path formed therein, an outer case surrounding the inner case, and a discharge flow path formed between the inner case and the outer case to communicate with the inner flow path. The discharge flow path including a circulation flow path branched from the inner flow path to guide air discharged from the blower fan unit, and a bent flow path branched from the inner flow path to guide the air discharged from the blower fan unit, the air is thereby bent a number of times in the bent flow path.
