Abstract: An information providing method using a mobile terminal is provided. The method includes placing the mobile terminal within a communication range of a sensor based Bluetooth Low Energy (BLE) device previously registered in the mobile terminal, receiving identification information and sensing information detected by the sensor based BLE device from the sensor based BLE device, extracting notification information corresponding to the received identification information of the sensor based BLE device, comparing a previously set reference sensing information included in the extracted notification information and the received sensing information, and outputting a notification message included in the notification information based on the comparison of the previously set reference sensing information and the received sensing information.

Abstract: A method of recommending a friend in a first terminal is provided. The method includes generating first interest keyword information by analyzing event information of the first terminal, receiving second interest keyword information of a second terminal, comparing the first interest keyword information and the second interest keyword information, and displaying information recommending a user of the second terminal as a friend based on a result of the comparing.

The control method includes displaying multiple windows for executing the multiple applications on the touch screen based on a display level of each of the windows, receiving a top-level display command for one of the multiple windows, fixing, as a top level, a display level of a top-level display window for which the top-level display command is received, and displaying the top-level display window in a level higher than the other windows.

Abstract: A method and apparatus for detecting location information using a navigation algorithm are provided. The method includes searching for neighboring Global Positioning System (GPS) satellites, receiving, if at least one GPS satellite is detected, pseudo-range information from at least one of the detected GPS satellites and storing the received pseudo-range information, calculating a displacement of a pedestrian terminal based on step detection of a pedestrian, correcting the calculated displacement of the pedestrian terminal using the received pseudo-range information, and measuring the location of the pedestrian terminal is measured using the corrected displacement.

Abstract: A method and apparatus of a portable terminal estimate a step length of a pedestrian. An accelerometer detects acceleration caused by a movement of the portable terminal as a pedestrian carrying the portable terminal walks. A gyroscope detects angular velocity caused by the movement of the portable terminal as the pedestrian walks. A controller determines a magnitude of a swinging motion of the portable terminal by using at least one of the detected acceleration and angular velocity, determines that the portable terminal makes the swinging motion when the magnitude of the swinging motion is equal to or greater than a predetermined value, determines a carrying position of the portable terminal in the pedestrian's body by using at least one of the detected acceleration and angular velocity, and estimates a step length of the pedestrian according to the determined carrying position of the portable terminal.

Abstract: Walking status estimation in a portable terminal includes a method for estimating walking status. The method includes setting an observation using an estimated temporary step length, an acceleration variance, and a step frequency. The method also includes generating an observed probability vector comprising probabilities per walking status according to the observation. The method further includes determining final probabilities per walking status by multiplying the observed probability vector by at least one of an initial probability matrix and one or more status transition probability vectors. The method still further includes determining a walking status having the greatest final probability as a final walking status.

Abstract: A method and system for estimating a step length in a pedestrian navigation system is provided. The method of estimating a step length in a pedestrian navigation system includes calculating a walking frequency and an acceleration variance of a pedestrian by using acceleration data acquired from an acceleration sensor, calculating a walking distance of the pedestrian by using GPS data acquired from a GPS receiver, and estimating a step length of the pedestrian by using the calculated walking frequency, acceleration variance, and walking distance.

Abstract: A wall-mounted type microwave oven including an improved coupling structure of a guide bracket to reduce manufacturing cost and manufacturing time is provided. The guide bracket has a hook protrusion at a front end, which is extended forwardly by a certain length. The base plate has a slot, into which the hook of the guide bracket is fitted. The guide bracket has a rear coupling portion at a rear end, which is extended laterally. The base plate has a rib to be in contact with the rear coupling portion. The rib has a hook at an upper end, by which the rear coupling portion of the guide bracket is held.
