  • Patent number: 10009734
    Abstract: An indoor location measurement system and method using RF signal transmitters. A DB stores spatial information of a predetermined space and location information of a plurality of RF signal transmitters installed in the space. A communication unit receives measurement information from a user terminal that has received signal including identification information of an RF signal transmitter output from the wireless signal transmitter. The measurement information includes the identification information and signal strength information of the wireless signal. A controller corrects the signal strength information when an object is determined to be present between the user terminal and of the plurality of wireless signal transmitters in the space based on the spatial information, the location information, and the signal strength information, and measures a current location of the user terminal based on the corrected signal strength information.

  • Publication number: 20170245116
    Abstract: A system and method for indoor positioning is disclosed. The indoor positioning system and method significantly improve accuracy of indoor positioning by measuring an indoor position using radiofrequency (RF) signals output from RF transmitters (e.g. a beacon) and by using position information measured by pedestrian dead reckoning (PDR) using sensing information obtained by sensing movement of a user terminal. For measuring an position inside a building using RF transmitters, error caused by internal structures of the building (walls, doors) can be corrected using spatial information (3D model of the building), positions of the RF transmitters, and information of a predetermined area allowed for user access inside the building.

  • Publication number: 20160353263
    Abstract: A method and system for providing indoor emergency alert is provided. An indoor emergency alert system obtains, from a user terminal, identification of an accessible beacon that is installed in a subspace of a building. The system recognizes identification of the subspace of the building corresponding to the identification of beacon obtained from the user terminal. Using the recognized identification of the subspace, the system maintains association between the subspace and the user terminal. When an emergency occurs at the building, the system can transmit a subspace-specific alert message to the user terminal based on the association between the subspace and the user terminal.

  • Patent number: 8878666
    Abstract: An emergency exit sign having a beacon module for indoor positioning and an indoor positioning system using the same are provided. The emergency exit sign includes a power supply unit, an AC/DC converter, an indoor positioning beacon module, an LED lamp, and a charger. The power supply unit receives an input of a power source and supplies the power source. The AC/DC converter converts the power source supplied and supplies a driving power source. The indoor positioning beacon module periodically wireless transmits a beacon signal including a beacon ID through a built-in antenna. The LED lamp is installed within the housing such that the lamp is positioned in rear of the display. When a power source is not supplied from the power supply unit, the charger supplies a driving power source.

  • Publication number: 20140172354
    Abstract: An incandescent socket connector having a beacon module for indoor positioning and an indoor positioning system using the same are provided. The incandescent socket connector includes a power supply unit, an AC/DC converter, and an indoor positioning beacon module. The power supply unit supplies an Alternating Current (AC) power source input from a main socket, to an electrode part of an incandescent lamp or a clip type Tri-phosphor lamp. The AC/DC converter receives an input of the AC power source from the power supply unit, converts the received AC power source into a Direct Current (DC) power source, and supplies a driving power source to the indoor positioning beacon module. The indoor positioning beacon module periodically wireless transmits the beacon signal including the beacon ID to the external.
