    Abstract: The present invention provides an optical component comprising a dielectric layer and a nanorod array; the nanorod array is formed on a surface of the dielectric layer and extends along a lateral direction and a vertical direction. The nanorod array comprises a plurality of nanorods extending along the dielectric layer. The nanorods have a gap between one another, and an angle is defined by two adjacent nanorods. A bump is formed at each of two ends of the nanorod.

    Abstract: An indoor positioning system based on building design information is disclosed. The system includes a server computer to provide indoor position information relating to a building, a plurality of beacons to be installed in selected locations in the building and to broadcast by each beacon an indoor position message indicating the indoor position of the beacon, and an installer to configure the beacons with their corresponding indoor position information. An indoor positioning system development system is also provided. The development system incorporates building information files and provides a development interface for users to determine respective locations to install the beacons. Once completed, the obtained results are converted into an indoor position message for each beacon and configured in the corresponding beacon.
