Systems and methods for assessing the effect of at least one of a plurality of forces acting upon a structure. Structural moment detectors, combined with external signal and data-processing components or structural information detectors which are unitary devices which include the signal and data-processing functions, are employed as an integral component of these systems. These systems include basic measurement systems, structural integrity measurement systems, applied structural measurement systems, applied load measurement systems, applied communication-detection systems and additional miscellaneous systems.

System for assessing the integrity of structural systems

A system for assessing the structural integrity of offshore drilling platforms employs structural moment detector and associated electronics, microprocessor and software, which monitors the condition of the offshore platform structure and continuously provides useful information concerning the effects of external forces on the structure and its remaining life.

Offshore platform structural assessment system

A system employing structural moment detectors for collecting and interpreting data reflecting the effect of at least a selected one of a plurality of forces acting on a structure such as a machine tool. The output signals from the moment detectors are processed to modify the information content (including rejecting components of the signals which reflect extraneous forces other than the selected one). The processed signals are then manipulated to provide secondary signals which are responsive to the condition of the structure as a result of the application of the selected force.

Machine health monitoring system

A self-contained, unitary device for collecting and interpreting data reflecting the effect of a force acting on a structure includes a housing adapted to be attached at spaced points to the surface of the structure, an optical sensor within the housing for detecting the relative orientation of spaced surface coordinate vectors of the structure, circuitry within the housing for converting signals from the optical sensor to a form usable by signal-processing electronics also located within the housing. The output of this structural information detector embodies useful information which directly indicates the effect of the force acting on the structure.

Structural information detector

Sensors are carried by structural components, such as floors, walls, etc., of the building within the secure area. The sensor detects deflections of the various structural members in response to changes of the loading of structural members caused by the intruder and generates signals which are transmitted to a control center which receives the intrusion signals and generates alarm signals. The intrusion signals are transmitted to the control center through the building structure as impulsive loads applied to the building structure by transducers located in the secure area which are responsive to the signals generated by the sensors. The alarm signals generated in the control center are transmitted to security systems located in the control center, such as automatic door locking mechanisms, lights, audible alarms, disabling gas injecting systems, etc., by means of coded impulsive loads applied to the building structure by transducers located in the control center which are responsive to alarm signals.

Structural moment detectors are carried by structural components, such as floors, walls, etc., within a desired secure area of a building structure. The structural moment detector detects deflections of the various structural members in response to changes of the loading of structural members caused by the intruder and generates signals which are transmitted to a control center which receives the intrusion signals and generates alarm signals. The intrusion signals are transmitted to the control center through the building structure as impulsive loads applied to the building structure by transducers located in the secure area which are responsive to the signals generated by the structural moment detectors. The alarm signals generated in the control center are transmitted to security system located in the secure area, such as automatic door locking mechanisms, lights, audible alarms, disabling gas injecting systems, etc., by means of coded impulsive loads applied to the building structure by transducers located in the control center which are responsive to the intrusion signals.
