Definitions
- This disclosure generally relates to systems for assessing the structural integrity of a building over time.
- Structures of any kind are designed to withstand the forces to which they are exposed and are regulated by various building codes that are enforced by the government. Forces to which structures can be exposed include earthquake, ground motion, wind, vibrations from nearby structures/facilities, explosions, landslides, volcanoes and others, herein defined as ‘incidents’. Codes and guidelines are designed to provide a best estimate that the integrity of a structure will survive an incident. However, once an incident has occurred, even if a building is ‘built-to-code’, it is necessary to make an independent, after-the-fact determination of the extent to which the structural integrity might have been compromised and whether the structure is safe to use.
- No currently available device is able to collect data in real-time about the structural integrity of a building. Strong motion instruments are installed in some buildings, but they provide information about the nature of the shaking that has affected the structure, not collecting data from the structure to assess what the shaking has done to that structure. Some applications have been developed that provide a warning that an earthquake wave is approaching. Another group of apps provides a static analysis of the damage that a hypothetical earthquake might do to a structure in the future. Neither of these types of apps determines what damage has been done to a structure nor do they provide an assessment of whether the structure is likely to be safe to occupy.
- the present invention provides continuous monitoring of the attributes of a structure before, during and after an incident. It then uses a proprietary algorithm further described below to assess how the structure has been affected and whether it is safe to occupy and use. This assessment is delivered within minutes after an incident to the people using the structure. In addition, results from all devices triggered by the event can be aggregated and made available to first responders, governmental disaster management teams and operators of critical facilities.
- the present invention uses an array of sensors to monitor the state of a structure continuously, which makes it possible to make an accurate assessment of the condition of a structure over time and, in particular, immediately after an incident. People can then quickly determine if the structure can be safely used. The invention also notifies people that the condition of the structure has changed so that the problem can be fixed to avoid an even greater disaster as well as loss of life.

Data is always processed using machine learning standards, and in the event a default value needs to be adjusted it does so automatically. In standard monitoring mode, the analysis of data is executed in the monitoring unit to determine if a single anomaly is present or relation-based anomalies between the sensors are involved. If all data points are within default value range, the system continues its routine standard monitoring schedule.

Incident recording: a recording that starts when the system is triggered and continues until the default values are back within range again.
- Incident process regardless of where the standard recording process is in the cycle, if one or more sensors indicate values outside the default value range, and trigger the system, the incident recording process begins and continue to record until the default values are back within range again, with an additional recording time to include the post-event data acquisition.

- the device will be registered using the mobile application.
- the user will mount the device at a high position on an interior wall of the structure.
- at least one sensor should be installed at a low position on an interior wall of the structure.
- the device will initiate a set of mechanical self-checks to assure correct installation.
- the invention will initiate communications with the remote data center which would conduct a series of functionality tests.
- the user would be asked to provide information about the structure (type, age, materials used, etc.) as well as the names and contact information of relevant parties.
- the device is now executing its operations without any user interactions.
- the user After an incident, and if the data recordings indicate sensor data outside the default value range, the user would, within a few minutes, obtain the analysis of how the incident affected the structure, including a recommendation and guidelines about the safety of the building. If the analysis concluded that the building was safe, the user could enter the building and resume regular use. If the analysis found that serious structural damage had occurred, the user would be advised to remain out of the building and seek help from a professional engineer. There is also the intermediate case where the analysis indicates that damage might have occurred. In this situation, the user would be given a careful explanation of what had been found, its uncertainties, and suggestions for how to proceed.
- Results from all devices triggered by an incident would be aggregated and can be made available to first responders so that they could understand the risk level before entering a structure, and to governmental disaster management teams so that they could begin planning the government response.
- the information would also be made available to operators of critical infrastructure and facilities so that they can better manage resources and safety issues after an incident.
- the result can be delivered as numeric values into third party computerized systems, rather than a text message. These numeric values can trigger other systems to execute commands of various kinds.
- the data acquisitions made before, during and after an event can be delivered as complete data recordings to insurance companies, local governments, first responders, emergency agencies, etc. to understand what happened to the structure in connection with the actual natural disaster event.
- the system can also be triggered by third party databases.
- third party databases are from USGS, ASCE, QCN, NWS, NEIC, or any other third party system, recording events from natural disasters. If the system is alerted from any of these third party databases about an incident, and the incident is outside the threshold value range, then the monitoring unit can be activated (triggered), unless not already triggered from its own sensors.
- the system detects material fatigue as a result of small and large vibrations, caused by environmental conditions including natural phenomena of various kinds. Over time, a structure will change its disposition and if this change is outside a threshold range, the system will be triggered and alert the user.
