Abstract:
A ventilation system and a controlling method of such a ventilation system are provided. The ventilation system may exhaust internal air from and draw fresh external air into a designated space. When an outdoor temperature is below a freezing point, some of the internal components of the ventilation system may be damaged due to the low external air temperature. This ventilation system controls operation of a supply fan and/or an exhaust fan based on the temperature of supplied and/or exhausted air to prevent such damage.
Abstract:
A bumper structure of a cleaning robot which detects whether or not an obstacle contacts a bumper and a position of the obstacle, allows the bumper to be simply process and reduces the number of components of the cleaning robot to lower the production costs of the cleaning robot. The bumper structure includes a main body, a bumper installed on the front surface of the main body, a resistance film provided between the main body and the bumper and fixed to the main body, and a metal film provided between the main body and the bumper and fixed to the bumper such that the shape of the metal film is deformed together with the bumper and the metal film comes into contact with the resistance film when at least one obstacle contacts the bumper, so as to measure resistance values.
Abstract:
The present invention relates to a game. More particularly, the present invention relates to a method, a server, a terminal, and a recording medium for proving a game having a function of enabling a user to easily recognize an item value of an item when the item usable within a game is displayed on a game screen.
Abstract:
A robot joint driving apparatus and a robot having the same are capable of minimizing a load applied to a drive motor by rotating a ball nut part such that a ball screw part performs linear movement in a power transmission structure using a wire and the ball screw apparatus. The robot joint driving apparatus includes a reversible drive motor, a ball nut part rotated according to operation of the drive motor, a ball screw part performing linear movement according to rotation of the ball nut part, a wire connected to the ball screw part from both sides of the ball screw part, an idle pulley rotatably installed at one side of the wire, and a joint part rotatably installed at an opposite side of the wire.
Abstract:
A compact exoskeleton arm support device compensates for gravity. The compact exoskeleton arm support device compensating for gravity may include at least five joints. Among the at least five joints, two joints may be driven by actuators, and the remaining joints may be driven by user force. The compact exoskeleton arm support device compensating for gravity effectively uses the actuators, thereby increasing operating efficiency and reducing production costs.
Abstract:
A robot cleaner system includes docking structure to allow a dust discharge port of a robot cleaner to come into close contact with a dust suction port of a docking station without an additional drive device. The robot cleaner system includes a robot cleaner having a dust discharge port, a docking station having a dust suction port to suction dust collected in the robot cleaner, and a docking device to perform a seesaw movement as it contacts the robot cleaner when the robot cleaner docks with the docking station, to allow the dust suction port to come into close contact with the dust discharge port. The docking device includes a link member installed in the docking station in a pivotally rotatable manner, one end having a contact portion to come into contact with the robot cleaner, and the other end having a docking portion defining the dust suction port therein.
Abstract:
A robot joint driving apparatus is smoothly operated without generation of backlash. A robot includes the robot joint driving apparatus. The robot joint driving apparatus includes an internal gear having a ring shape, a main pulley arranged at the center of the internal gear and connected to a power source, first and second pinion gears provided at both sides of the main pulley and engaged with the internal gear, first and second pulleys respectively fastened to the first and second pinion gears, first and second belts respectively connecting the main pulley and the first and second pulleys, and tension adjustment units to adjust tensions of the first and second belts.
Abstract:
The invention relates to an apparatus for preventing infection by malicious code, comprising: a database in which files installed in an agent system, DNA values for each part of the files, and index information for indicating whether each file is normal or malicious are stored; a calculation unit which calculates a DNA value for a part of a file for which an execution is requested in the agent system; and a file inspection unit which searches the database to extract, in a group, files having the DNA value calculated by the calculation unit, inspects whether an object file is normal or malicious on the basis of the index information on the files extracted in a group, and allows the execution of the object file or makes a request for the calculation of DNA values of other parts which selectively include one part of the object file.
Abstract:
Disclosed is a compliant joint achieving passive compliance. The compliant joint includes a housing and a rotating member mutually rotatably provided; and a cam provided between the housing and the rotating member, and connected to the housing and the rotating member respectively. The cam is connected to the rotating member to rotate together with the rotation of the rotating member, or be independent of the rotating member so as to move in the axial direction of the rotating member separately from the rotating member. The cam is connected to the housing such that the cam can maintain the connection with the housing when external force below a designated value is applied to the rotating member, and release the connection with the housing in the case that external force more than the designated value is applied to the rotating member.
Abstract:
The present invention relates to a ventilating apparatus and to a method for controlling the ventilating apparatus. More particularly, the present invention relates to a ventilating apparatus comprising a humidifying unit having an antibiotic function, as well as to a method for controlling the ventilating apparatus.
