Abstract: An air-conditioning apparatus includes a heat pipe, which performs heat exchange. The air-conditioning apparatus provides supply air in a set state (temperature, humidity) through a change in the flow passage of ventilation air and outside air by the selective opening/shutting of dampers, cooling the outside air by spraying mist, and cooling and humidifying the supply air. The cooling temperature and humidity of the supply air is controlled at a ratio of the ventilation air passing through a cooling coil and the ventilation air passing through a bypass passage. Using a bypass passage, ventilation air can directly move to an air supply block without the intervention of the cooling coil within a heat exchange block through which a ventilation air passes.

Abstract: A method and a system for recognizing an input by using an index of a variable grid are disclosed. An input recognition method carried out by an electronic device implemented by a computer comprises the steps of: generating a virtual grid of which the distance between lines is variable, in correspondence with at least a partial region of a display included in or connected to the electronic device; and recognizing, by using an index of the virtual grid, a position selected by a user of the electronic device in the region of the display corresponding to the virtual grid.

Abstract: Disclosed is an air-conditioning apparatus using a heat pipe. The state of the outside air is compared with the state of set supply air. The heat exchange and mixed supply of outside air and ventilation air are effectively performed by changing the passage of the ventilation air and the outside air through the selective opening/shutting of dampers, cooling the outside air through latent heat by spraying mist, and by controlling supply air in a set state through the cooling and humidification of the supply air. Accordingly, energy efficiency can be improved and the energy necessary for the air-conditioning apparatus can be reduced using the evaporation latent heat of water. Furthermore, operation costs can be reduced and financial gains can be obtained because an efficient operation can be performed in response to the state of a measured outside air.

Abstract: A method for providing a video to a viewer terminal through a communication network includes: receiving, by a communication unit, an original video signal including information of an original video; generating, by a controller, a delayed video signal including information of a delayed video in which the original video is delayed by a first time period; transmitting, by the communication unit, the original video signal to a subtitler terminal; receiving, by the communication unit from the subtitler terminal, a subtitle signal including information of subtitles with respect to the original video and a subtitle delay signal including information for delaying a display of the subtitles; generating, by the controller, a display timing signal indicating a timing of displaying the subtitles on the delayed video, based on the subtitle delay signal; transmitting, by the communication unit, the delayed video signal to a viewer terminal; and transmitting, by the communication unit, the display timing signal and the subt

Abstract: Provided is a server room cooling device including: an outer air inflow unit into which outer air flows; a filter unit provided at one side of the outer air inflow unit and filtering the outer air supplied through the outer air inflow unit; a mist ejection unit provided at one side of the filter unit and ejecting mist into the outer air that has passed through the filter unit; and a supply unit provided at one side of the mist ejection unit and supplying the outer air that has passed through the mist ejection unit to a server room.

Abstract: A method and a system for providing integrated indoor and outdoor positioning are disclosed. The method for providing integrated positioning may comprise the steps of: receiving, by a user terminal, GPS coordinate information of the user terminal moving in an outdoor area around a building and an outdoor area within the building; and determining, by the user terminal, information on an area in which the user terminal is located and a floor on which the user terminal is located in the building, on the basis of GPS coordinate information mapped to each of the outdoor area around the building and the outdoor area within the building and the received GPS coordinate information.

Abstract: A cooling air supplying booth apparatus for supplying cooling air to pieces of equipment in a rack unit includes a first frame and a plurality of plates. The first frame forms edges of a cuboid. The plates are fixed to the first frame and disposed at four of sides of the cuboid and form a cooling air moving path. A cooling plate includes at least one fan and is disposed at the bottom of the first frame opposite the top side of the first frame. Cooling air is supplied to the cooling air moving path through the fan, and supplied to the equipment through an outlet side in the cooling air supplying booth apparatus.

Abstract: Disclosed are a method and a system for providing an indoor positioning service. A method for providing an indoor positioning service comprises receiving a request to provide an indoor positioning service from a user terminal; receiving, in response to the request, information for wireless access points located near the user terminal; calculating the similarity between the items of information, and accuracy of the locations of the wireless access points on the basis of the received information for the wireless access points and information for the wireless access point collected from each point positioned inside the building; and determining the current location of the user terminal on the basis of the similarity and accuracy of the location.
