Abstract: A remote management system and method having an automatic update function, the system including: a remote management controller located remotely from at least one air conditioner system so as to perform a central control for the air conditioner system(s); and a local controller installed between the air conditioner system(s) and the remote management controller so as to update management programs of the air conditioner system(s) after downloading necessary information by periodically connecting with the remote management controller through a network, whereby accordingly, the local controller can be efficiently updated by using the remote management system, thereby enhancing the system administrator's convenience.

Abstract: A lighting device controller which controls a lighting device and provides a signal to an air conditioner controller indicating an operation state of the lighting device, and an air conditioner controller which receives a signal from a lighting device controller indicating an operation state of a lighting device, and controls an air conditioning unit corresponding to the lighting device in response to the signal are disclosed.

Abstract: In a binary keypad apparatus for a portable terminal, a power supply supplies a current, and one or more general keys receive the current from the power supply and output the received current. One or more general purpose input/output (I/O) pins receive the current and output binary values corresponding to the received current.

Abstract: A sliding/folding-type portable terminal includes a first housing; a second housing coupled to the first housing in such a manner that it can rotate in a direction moving away from a state facing the first housing or approaching it; a third housing coupled to the second housing in such a manner that it can linearly reciprocate; and a first elastic means adapted to provide a rotation force for rotating the second housing away from the first housing, wherein the third housing is adapted to engage the first housing and restrict the rotation of the second housing, when the second housing faces the first housing, and to be released from the first housing upon linearly traveling on the second housing.

Abstract: Disclosed is a method for operating an application and a mobile terminal used therefor. A key input unit receives a key value to operate an application. A memory stores one or more applications and key values preset for the applications. A display unit displays a screen for operating the application in response to a key value input through the key input unit. A controller retrieves key values, preset for applications, including the key value input through the key input unit from the memory. The controller displays names of the applications mapped to the retrieved key values. When a key is input to operate a predetermined application among the applications of the displayed names, the controller operates the predetermined application.

Abstract: Disclosed are a device for tracing a movement of a mobile robot and a method thereof. The device for tracing a movement of a mobile robot includes: a camera for capturing a specific object; a movement tracing and image generating unit for setting a reference area in the present image produced by capturing the specific object by the camera and generating the present image in which the reference area is set; a difference image extracting unit for extracting a difference image of pixels of the edge of the reference area of the present image and pixels of the reference area of a previous image; and a microcomputer for tracing a movement of the specific object based on the extracted difference image.

Abstract: An apparatus for calling a mobile robot includes a generator installed at a remote controller, and generating an RF signal and infrared signal for calling a mobile robot when a call signal is inputted by a user; and a controller installed at the mobile robot, calculating a direction of the remote controller based on a position of an infrared ray receiver that receives the infrared signal when an RF signal is received, rotating the mobile robot in the calculated direction, and then making the mobile robot to go straight ahead. When a user calls the mobile robot from a specific place, the mobile robot can move by itself to the specific space, thereby enhancing users' convenience.

Abstract: Provided is a detector, a gas scrubber comprising the detector for identifying a residual lifetime of an absorbent material contained in a gas scrubber for purifying a harmful exhaust gas, and a method of identifying the residual lifetime of the absorbent material. The detector comprises a solid chemical material, the color of which changes when it comes in contact with the untreated exhaust gas due to loss of absorbing power of the absorbent material, a detection window containing the solid chemical material therein, therethrough the visual identification of the color change of the solid chemical material can be made, and connecting units placed on an upper and lower end of the detection window. The visual identification of the color change of the solid chemical material through the detection window enables the continuous and safe identification of the residual lifetime of the absorbent material and the replacement time, thereby increasing the reliability of the gas scrubber.

Abstract: There is provided a semiconductor manufacturing apparatus comprising: a cassette station 16 in which wafers 18 are loaded; a stand-by conveying robot 10 for taking the wafers 18 out of the cassette station 16; a load lock chamber 12 in which the wafers 18 taken by the stand-by conveying robot 10 are accommodated; and a reaction chamber 14 placed in contact with the load lock chamber 12, the reaction chamber 14 having a shuttle blade 20 for drawing the wafers accommodated in the load lock chamber out of the load lock chamber 12 in a vacuum state and loading etched wafers in the load lock chamber, a rotary robot 26 for rotatively transferring the wafers taken out of the load lock chamber to be placed on the shuttle blade 20, and a heater stage 24 for etching the wafers transferred by the rotary robot 26 using a plasma generator 28, in which a pre-heating part 22 is placed above the shuttle blade 20, for pre-heating the wafers transferred into the reaction chamber 14 from the load lock chamber 12 before they are
