Abstract

A system is disclosed for being affixed to a portion of a construction structure that has sustained a fracture. The system can provide a repair strap, sensor and communication interface. The repair strap can be securable to the structure to span at least a portion of the fracture. The sensor can be carried on the repair strap and be configured to detect at least one condition representative of additional fracture of the structure. An electrical signal can be generated in response to said detection. The communication interface can be electrically coupled to the sensor and can receive the electrical signal generated by the sensor. The communication interface can be configured to transmit information to a remote electronic device via a public or private communication network.

Claims
