141 Autonomous Sensing Module, a System and a Method of Long-Term Condition Monitoring of Structures US12767779 2010-04-26 US20100271199A1 2010-10-28 Nickolai Belov; Olga Belova
A system and a method of long-term condition monitoring of structures are based on use of autonomous sensing modules, centers for storing and processing data and software for data analysis. An autonomous sensing module contains a set of sensors for measurements of parameters related to the condition of a monitored structure, a non-volatile memory, a wireless data transfer unit, a controller, a clock circuit, a battery, an energy harvesting device and a power management unit. The autonomous sensing module provides a very long-term (40 years or more) functionality and reliability due to both use of at least near hermetic packages for the controller, the non-volatile memory, the battery, the clock circuit and the power management unit and choosing the duration of periods when the sensing module works in active mode in such a way that the average energy consumed by the autonomous sensing module is fully compensated by the average energy harvested by the energy harvesting device.

145 STRUCTURAL HEALTH MONITORING SYSTEM HAVING MEMORY ON STRUCTURE US12432668 2009-04-29 US20100114503A1 2010-05-06 Chang ZHANG; Xinlin QING; Irene Li
Storage of information, such as baseline information and structure ID, in a memory that is mounted on the structure, rather than inside the diagnosis hardware. This allows for faster and more convenient information retrieval. In particular, this approach allows for a more modular system in which different diagnosis hardware or other analyzers can be simply plugged into a structure's sensor network, whereupon they can quickly download any desired structure-specific information (e.g., baseline information, structure ID, and other useful information) from the on-structure memory.

148 Method for satisfying certification requirements and verifying the integrity of structural health management systems US11142038 2005-05-31 US07366627B2 2008-04-29 Grant A. Gordon; Nicholas J. Wilt; Joseph J. Nutaro
A method is disclosed wherein a plurality of sensors mounted on a structure, a baseline data set for each of the plurality of sensors and a calibration procedure verify the integrity of a structural health management system. Initially a baseline data set is established. Before performing the structural health assessment a calibration-in data set for each of the plurality of sensors is collected. The calibration-in data set is compared to the baseline data set for each sensor of the plurality of sensors. If the calibration-in data set and the baseline data set match then a structure characterization is performed. If the calibration-in data set and the baseline data set do not match, a calibration-out procedure is performed to generate a calibration-out data set. If the calibration-out data set and the calibration-in data sets match, then a determination is made that the structural health management system was working.
