Abstract: Disclosed is a system for preventing drunk driving of a vehicle, the system including: an input unit through which a transfer intention to transfer a control privilege of a vehicle from a registered driver to a passenger is input; a sobriety determination unit configured to determine a current driver's inebriation state through a breathalyzer provided in the vehicle when the transfer intention is input through the input unit; a driver verification unit configured to identify personal information of the current driver seated on a driver's seat; and a control unit configured to transfer the control privilege of the vehicle to the passenger when the passenger is measured as being able to drive by the sobriety determination unit and the passenger and the current driver are identified to be the same by the driver verification unit.

Abstract: Disclosed are a drunk driving prevention system and a drunk driving prevention method using the system that includes a sensor module measuring the alcohol content in exhaled breath of a driver at the time of breath-checking of the driver and a control module configured to check an intoxication state of the driver based on the alcohol content measured by the sensor module to determine whether or not a breath-checking is complete and block an engine start when the breath-checking fails, wherein the control module includes a bypass control unit switching a vehicle into a drivable state when the breath-checking fails.

Abstract: According to the present disclosure, a drunk driving prevention system including: an alcohol detection unit configured to detect a driver's inebriation through the breath test device provided in a vehicle; a computation unit configured, when the driver is detected to be in a drunk state by the alcohol detection unit, to compute a driving-possible time at which the drunk state is resolved in the future so that driving is possible; and a notification unit configured to output the driving-possible time or whether or not driving is possible through an infotainment system of the vehicle or a driver's terminal is disclosed.

Abstract: Disclosed are a drunk driving prevention system and a method of controlling the system that includes a sensor module measuring a alcohol content in the exhaled breath of a driver during a breath-checking of the driver and a control module configured to check the intoxication state of the driver from the alcohol content measured by the sensor module to determine whether the breath-checking is complete and block an engine start when the breath-checking fails, wherein the control module includes a check unit displaying breath-checking guide information through a display unit and the check unit displays the breath-checking guide information based on an engine start input of the driver.

Abstract: The present invention determines whether a vehicle is traveling at a location where preparation is needed for the vehicle to exit to another road branching from a current traveling road, estimates a lane change intention of a driver when it is determined that a lane change is needed for the vehicle to exit the current traveling road, and communicates the lane change to neighboring vehicles by activating a turn signal when the lane change intention is estimated.

Abstract: The present disclosure relates to a cleaner including an improved structure to enable self-standing. The cleaner includes a head main body including a brush, a main wheel coupled to the head main body to be positioned in the rear of the brush, a suction pipe disposed between the brush and the main wheel to enable self-standing, a connector configured to connect the suction pipe and the head main body, and a hose having an elasticity such that the suction pipe maintains a self-standing state and disposed between the head main body and the connector.

Abstract: The present disclosure relates to a vacuum cleaner capable of enhancing the convenience of use with an improved handle structure. The vacuum cleaner includes a cleaner main body disposed along a longitudinal direction of a suction nozzle and provided to generate a suction force, and a handle provided on the cleaner main body to be gripped and manipulated by a user, wherein the handle includes a first button provided to select on or off of the cleaner main body, and a second button provided to selectively adjust the suction force.

Abstract: A method for manufacturing a semiconductor device includes: forming a sacrificial layer on a first substrate, the sacrificial layer being made of a material whose lattice constant is different from that of germanium (Ge) by a preset threshold or below; forming a germanium (Ge) layer on the sacrificial layer; forming an insulation layer on a second substrate; bonding the germanium (Ge) layer onto the insulation layer; and removing the sacrificial layer and the first substrate by etching the sacrificial layer in a state where the germanium (Ge) layer is bonded to the insulation layer. In this method, a germanium-on-insulator (GeOI) structure having various surface orientations may be formed by means of epitaxial lift-off (ELO), and a strain may be applied to the germanium (Ge) layer using a lattice constant of the sacrificial layer.

Abstract: There is provided an apparatus for detecting a musical note of an instrument comprising a sensor unit including a sensor configured to sense a vibration of the instrument and a control unit configured to identify a component of the musical note based on a frequency of the vibration recognized by the sensor unit, wherein the sensor unit is connected to a port of a microprocessor of the control unit through a first route to transfer the recognized vibration, and wherein the sensor unit is selectively connected to a port of the microprocessor through a second route different from the first route to output a sound based on a signal supplied from the microprocessor.
