Abstract: A docking station for a cleaner including a docking unit including an upper surface forming a travel route along a first direction for a robot cleaner to move upon to enter the docking station; and a floorcloth separator including a protrusion, and configured so that the protrusion protrudes from a predetermined area of the upper surface of the docking unit such that a free end of the protrusion is defined along a second direction different from the first direction, and while a robot cleaner with a floorcloth attached thereto travels on the travel route along the first direction, at least a portion of the protrusion is inserted between the robot cleaner and the attached floorcloth to separate the attached floorcloth from the robot cleaner.

Abstract: A docking station including a docking unit providing a traveling path for a robotic vacuum cleaner, having a mounted mopping cloth, that enters the docking unit; a mopping cloth separator disposed on the docking unit and configured to automatically separate the mounted mopping cloth from the robotic vacuum cleaner while the robotic vacuum cleaner is at a first position along the traveling path; and a mopping cloth coupler disposed on the docking unit and configured so that, after the mounted mopping cloth is separated from the robotic vacuum cleaner, and the robotic vacuum cleaner thereafter moves to a second position along the traveling path, the mopping cloth coupler supplies a mopping cloth to be mounted to the robotic vacuum cleaner from below the traveling path while the robotic vacuum cleaner is at the second position.

Abstract: A robot cleaner includes a rotation motor; a rotation member that is rotatable by driving of the rotation motor having a first surface, a second surface, and an opening through the rotation member and penetrating the first surface and the second surface; and a floorcloth coupling member disposed on the second surface and having a floorcloth attaching unit insertable into the opening to be detachably coupled to a floorcloth in contact with the first surface. The rotation member and the floorcloth coupling member are configured so that, when the floorcloth attaching unit is inserted into the opening and detachably coupled to the floorcloth, the rotation member rotates in a first state, the floorcloth attaching unit remains coupled to the floorcloth. When the rotation member rotates in a second state, the floorcloth attaching unit exits the opening so that the floorcloth becomes detached from the floorcloth attaching unit.

Abstract: A docking station for a robotic vacuum cleaner may include a docking unit having a traveling path for the robotic vacuum cleaner to enter the docking station and travel to a mopping cloth attachment position where a mopping cloth is attachable to the vacuum cleaner. The docking station also includes a mopping cloth supply unit disposed above the docking unit and configured to receive a plurality of mopping cloths, and the plurality of mopping cloths are side by side along a horizontal direction. The mopping cloth supply unit may include a mopping cloth transporting unit that are configured so that the mopping cloth transporting unit sequentially transports each mopping cloth of the plurality of mopping cloths received by the mopping cloth supply unit along the horizontal direction to an outlet to be discharged through the outlet to the mopping cloth attachment position.

Abstract: A robot cleaner includes a motor, a rotating-shaft member, and a rotation member coupled to the rotating-shaft member and including a cleaning member coupling configured to be detachably coupled to a plurality of cleaning members. The motor, rotating-shaft member, and the rotation member are configured so that the motor is drivable to rotate the rotating-shaft member and thereby cause the rotation member to move in a first direction or a second direction opposite to the first direction, along a longitudinal direction of the rotating-shaft member. In a case that the rotation member moves in the first direction with the cleaning member coupling detachably coupled to the plurality of cleaning members, at least one cleaning member of the plurality of cleaning members becomes detached, and is thereby released, from the cleaning member coupling.

Abstract: A control device and face plate is described, where the faceplate includes a first region formed from a first material that is non-conductive, a second region that is formed a second material that is transparent to infrared radiation, and where the first region and the second region are seamlessly joined to form a unitary structure.

Abstract: An LED bulb includes a base and a shell connected to the base. The shell is filled with a thermally conductive liquid for cooling the bulb. A plurality of LEDs is disposed within the shell. A first set of LEDs of the plurality of LEDs is positioned a first distance with respect to the center of a convex portion of the shell, and at a first angle with respect to a centerline of the LED bulb. A second set of LEDs of the plurality of LEDs is positioned a second distance with respect to the center of the convex portion of the shell, and at a second angle with respect to a centerline of the LED bulb. The first distance, first angle, second distance, and second angle are selected such that the LED bulb has a light-distribution profile that varies less than 20 percent in light intensity over 0 degrees to 135 degrees as measured from an axis from the center of the shell through an apex of the shell.

Abstract: A light emitting diode (LED) bulb includes a base, a shell connected to the base forming an enclosed volume, a chassis disposed within the shell, and a plurality of LEDs disposed with the shell. The LED bulb also includes a thermally conductive liquid disposed within the enclosed volume. The LEDs and the chassis are immersed in the thermally conductive liquid. The chassis has a first opening and a second opening. The second opening is spaced from the first opening to facilitate a passive convective flow of the thermally conductive liquid to exchange a first volume of the thermally conductive liquid interior the chassis with a second volume of the thermally conductive liquid exterior the chassis.
