Abstract: A mask forming method includes providing preliminary mask data including a Manhattan path such as a quadrangle, a bar, a polygon or a combination thereof based on a layout. Mask data including a curvilinear shape is prepared by correcting the preliminary mask data through application of an elliptical function, a B-spline curve, or a combination thereof. A mask pattern is formed on a mask substrate based on the mask data.

Abstract: A system is provided for exchanging or trading real estate information. The system includes a real estate property, a beacon configured to be installed or attached to the real estate property, and a server on a network. The beacon is configured to transmit short-range signals to a mobile device of a user. The mobile device is configured to receive information on the real estate property from the server over the network and present the information to the user who is determined to be near the real estate property.

Abstract: The invention relates to construction method for social networking platform on based beacon comprising frame with the re-extraction process based on the position of various information processed by the server and users this information and also it's own making can share in the beacon based on the social networking information for the wireless communication protocol of the Bluetooth frequency beacon Additionally, in conjunction with the present method for the platform and other system information as one of a methodology to establish a build platform user smart devices or only a range of location-based information services to the user through the terminal platform as the system. Frequency appearing through the beacon is a Serial Number role in a specific location by its own value for that particular location.

Abstract: The invention relates to a location-based services and related information systems using a virtual beacon device comprising Virtual Beacon Architecture Diagram1 is when the base station receives a frequency signal of 100 Number by a view of the structure of a virtual beacon 101 separated from the signal of one unit and the Pico cell selection to the base station signal of the smallest unit of 102 to give it a specific Identity and it gives a number sequence in it. And the assigned sequence number is converted to a Cell of Location sector as a minimum unit on the physical space. The transformed cell is converted to a single Cell of map 103. This will divide the map of the physical space in the form of a Cell on a minimum unit. Cell thus the divided minimum unit is the display position of the virtual beacons on each of the Flag value by ON/OFF type. That is, ON is 1 is OFF will be zero.

Abstract: The invention relates to A Construction Method for Connecting Information System on Based Beacon comprising: he Access Point 101 and 102 continually Diagram1 Broadcasting a predetermined frequency as a beacon To do this, one broadcasting frequency was accepted by 103 104 user applications are single-user mode is interlocked with 105 single-user mode to the administrator mode information; shown in Administrator mode is set and all transport in the form Sorting in administrator mode, an administrator application position may also be located on the server and not be limited to the user terminal smart devices. This user mode and administrator mode can be collectively managed through a single integrated management system program 111. The exchange of data is usually performed only in administrator mode and 105 number.

Abstract: A method for process proximity correction may include obtaining a point spread function (PSF) from test patterns, the test patterns including an etching process performed thereon, generating a target layout with polygonal patterns, dividing the target layout into grid cells, generating a density map including long-range layout densities, each of the long-range layout densities being obtained from the polygonal patterns located within a corresponding one of the grid cells, performing a convolution of the long-range layout densities with the PSF to obtain long-range etch skews for the grid cells, and generating an etch bias model including short-range etch skews and the long-range etch skews, each of the short-range etch skews being obtained from a neighboring region of a target pattern selected from the polygonal patterns in each of the grid cells.
