Abstract: A device and control method for driving a sensorless brushless DC (BLDC) motor, particularly related to a technology configured to increase the accuracy of detection of Zero Cross Point through a non-commutation period in a pulse width modulation (PWM) control. The device for driving a sensorless BLDC motor to switch a current applied to a stator winding based on a position of a rotor includes a three phase inverter configured to convert a DC input voltage into a three phase AC voltage and supply the three phase AC voltage to the BLDC motor; a terminal voltage detector configured to detect a three phase terminal voltage from an output terminal of the three phase inverter; and a controller configured to perform a PWM control of the terminal voltage based on a three phase back electromotive force (EMF) included in the detected terminal voltage. The PWM control includes a non-commutation control in which the switching of the current does not occur.

Abstract: A robot cleaner capable of vacuuming foreign materials on a floor includes a main body to which a dust collector is mounted and a vacuuming unit provided at a front portion of the main body to clean a floor. The vacuuming unit is configured to move relative to the main body. If it is determined that the robot cleaner is located near a wall or an obstacle, the vacuuming unit moves to the wall or the obstacle. Since the vacuuming unit contacts the wall or the obstacle, a region of a floor near the wall or the obstacle may be cleaned. Further, a manual cleaner may be selectively connected to a channel connector of the robot cleaner so that a user may choose automatic or manual cleaning of a floor at the user's convenience.

Abstract: Disclosed are a printing media holder and an image forming apparatus including the same. The printing media holder includes an printing media alignment unit capable of moving bidirectionally toward and away from the printing media loaded on the printing media holder, and includes a release mechanism that releases the printing media alignment unit, to allow the printing media alignment unit to move its position for aligning of print media of different sizes, in response to a force received thereto in any of the bidirectional directions.

Abstract: A method and apparatus for effectively managing image files are provided. The apparatus acquires a second image if a link information input signal is input. If a person is recognized from the second image, text information corresponding to the recognized person may be added to link information of a first image. Also, an image of the second image may be added to the link information of the first image.

Abstract: Provided are an apparatus and method of providing path information based on a status of a path and/or a purpose of the use of the path. A path information providing server collects environmental information from a sensing device. The path information providing server receives a path information request including a departure and a destination from a terminal device, and provides path information generated by mapping environmental data to a searched path.

Abstract: A cleaning robot and a control method thereof may improve power consumption efficiency by using low-voltage power for a moving or inspecting operation and performing the moving or inspecting operation while operation of the cleaning unit is stopped when the operation of the cleaning unit is not needed. The cleaning robot includes a battery, a moving unit, a cleaning unit, a power converter which converts and outputs power supplied from the battery into a first voltage driving the moving unit and a second voltage driving the cleaning unit, and a controller which supplies power having the first voltage to the moving unit so as to drive the moving unit and supplies power having the second voltage to the cleaning unit so as to perform a cleaning operation. The controller continues driving the moving unit but stops driving the cleaning unit when the cleaning robot moves on an already cleaned area.

Abstract: A robot cleaner that sweeps dust on the floor toward its center and absorbs the dust through a small-area inlet with a strong suction force, by a cleaning tool that integrates functions of side brushes and a main brush into one. The present disclosure also provides a robot cleaner that enables a large-diameter foreign material to be guided to and effectively absorbed through the inlet without interference by a cleaning tool. The robot cleaner includes a main unit including a fan motor and a dust collector and having an inlet arranged on a base to absorb foreign materials, and a cleaning tool arranged in the bottom of the base, extending to a front side of the base from the inlet and guiding a foreign material on a floor to a side of the inlet, wherein the cleaning tool is arranged to be movable by an external force.
