The present invention relates to network enabled analysis of x-ray images. An anchor bolt according to the present invention includes a first anchor bolt 2 having an embedded portion shorter than a reinforcement covering margin, a second anchor bolt 7 having an axis at a position deflected from an axis of the first anchor bolt 2, and a coupling member 5 integrally fixing the first anchor bolt 2 and the second anchor bolt 7. A death of a first process node in the network ring can be detected by a second process node, when the second process node notices that its connection to the first process node has closed. Majority voting logic with an output coupled to configuration inputs of the data array and inputs coupled to each of the redundant configuration arrays may be employed. The first file is compared with the second file to verify an accuracy of the mediation system. The test die includes the test circuitry and the product die includes the product circuitry.
