  • Patent number: 11966867
    Abstract: A technique includes displaying, by a computer using a graphical interface, a map of a geographical area, where the map includes political boundaries. The technique includes displaying, by the computer, graphical images on the map representing a plurality of aspects that are associated with the management of a plurality of projects as corresponding geographical features on the map. The technique includes graphically segregating, by the computer, the plurality of projects on the map using the political boundaries; receiving input, via interaction with the displayed map; and changing, by the computer, in response to the interaction, how a given aspect of the plurality of aspects of a given project of the plurality of projects is represented on the map.

  • Patent number: 10103104
    Abstract: A package carrier including a flexible substrate, a first build-up structure and a second build-up structure is provided. The flexible substrate has a first surface and a second surface opposite to each other, and has a first opening connected between the first surface and the second surface. The first build-up structure is disposed on the first surface and covers the first opening. The second build-up structure is disposed on the second surface and has a second opening, and the first opening and the second opening are connected to each other to form a chip accommodating cavity together. In addition, a manufacturing method of the package carrier and a chip package structure having the package carrier are also provided.
