Abstract: A smart real estate foundation monitoring system is disclosed. The system is configured to provide real-time visibility into the health and integrity of a real estate's foundation. The system utilizes a network of sensors, strategically located within a real estate, to continuously measure the physical stresses exerted on the real estate frame to detect wall deflections, structural cracks, and foundation movements. The smart real estate foundation monitoring system serves as a valuable early warning system which can detect problems before they arise. The system integrates with a real estate's existing Wi-Fi to securely stream sensor data to a cloud server where it is further processed and analyzed to generate alerts, dashboards, and reports.

Abstract: Systems and methods are provided for wirelessly communicating with multiple sensors. In particular, a multi-sensor platform is provided that acts as an intermediary node and can communicate with multiple integrity sensors. The integrity sensors are each coupled via a wired connection to the multi-sensor platform, and the multi-sensor platform is powered wirelessly by a radiofrequency transmitter. The radiofrequency transmitter can receive data from multiple sensors via one node, the multi-sensor platform, thus allowing the radiofrequency transmitter to have a static transmission beam.

Abstract: Due to geometric discontinuities introduced by welding and joining processes, stresses or strain cannot be calculated reliably calculated using modern analytical and computer methods as result of stress or strain singularity at joint locations, which leads to severe mesh sensitivity. Design and fatigue evaluation of these structures remain empirical. This disclosure addresses mesh insensitivity of stress/strain calculations for welded structures through a cut-plane traction stress method through a novel post processing of conventional finite element computation results, as well as provides a unified fatigue evaluation procedure for fatigue design and structural life evaluation for both low-cycle and high cycle fatigue regime subjected to either proportional or non-proportional multiaxial fatigue loading, as well as a simple and reliable method for treating spot welds.

Abstract: A system for measuring displacements of a blade root of a rotor blade of a wind turbine includes a hub, and a rotor blade coupled to the hub by a pitch bearing. The system further comprises a reference plane and at least one displacement sensor. The reference plane is configured to move with the rotor blade as the rotor blade moves relative to the hub while the displacement sensor is fixed to the hub and the displacement sensor is configured to detect a displacement of the reference plane relative to the hub without physical contact. Alternatively, the reference plane has a fixed position with respect to the hub while the displacement sensor is fixed to the rotor blade and the displacement sensor is configured to detect a displacement of the reference plane relative to the rotor blade without physical contact.

Abstract: Determining an active jacking force of a tunneling closely undercrossing existing station, includes: acquiring design parameters of stations, and geological parameters of a construction site; obtaining a stress solution expression of the active jacking force on the existing station to obtain a stress solution of any point in a semi-infinite space under the action of a vertical load, replacing the vertical load with a vertical load acting on the existing station, and obtain a vertical stress solution of the existing station; obtaining a relational expression between the deflection and the stress solution of the existing station; and substituting the stress solution expression of the active jacking force into the relational expression between the deflection and the stress solution of the existing station according to boundary conditions at both ends of a beam on elastic foundation to obtain the active jacking force that controls the deflection of the existing station.
