  • Publication number: 20190394615
    Abstract: A server may include a communication circuit communicating with a user terminal, storage including a fingerprint DB storing fingerprints corresponding to a plurality of points and a signal fluctuation probability DB, and a processor electrically connected to the communication circuit and the storage. The processor may be configured to store similarity between first signal strength and second signal strength, which are determined based on a probability that a pair of the first signal strength and the second signal strength received from a first AP occurs with respect to fingerprints corresponding to a first point, in the signal fluctuation probability DB, to obtain a fingerprint including signal strength received from the first AP, from the user terminal, and to determine a location of the user terminal based on the obtained fingerprint and the signal fluctuation probability DB.

  • Publication number: 20190257572
    Abstract: Provided is a refrigerator which allows a pivoting bar to pivot to seal a gap between a pair of doors regardless of whether the door at which the pivoting bar is not installed between the pair of doors is open or closed. The refrigerator includes a guide device which induces the pivoting bar to pivot. Here, the guide device includes a rack that is moved forward and backward linearly depending on opening and closing of the second door and includes a second magnet built therein, a pinion gear engaged with the rack and pivoting when the rack is moved linearly, and a guide unit which includes a guide groove guiding a guide protrusion and is engaged with the pinion gear to move linearly in a direction opposite to that of the rack to allow the pivoting bar to pivot when the pinion gear pivots.
