123	Calculating Fatigue and Fatigue Failure of Structures	US14273781	2014-05-09	US20140336954A1	2014-11-13	Michael Bruyneel; Stijn Donders; Michael Hack; Christophe Liefooghe; Peter Nuhn; Stefan Strässer
The durability performance of a structure is virtually predicted, enabling the optimization of the durability performance. In a first act, the structure is modeled by a series of calculation points. Then, for each point, the stresses and strains brought by load cycles and defining hysteresis branches are determined. Then, an accumulated damage due to the load cycles is predicted and stored. For the prediction, first, using a hysteresis operator, a change in the stress along a portion of a hysteresis branch is calculated as a function of a change in the load in time, and, second, using the change in the stress and the stored accumulated damage, a change in the damage is calculated. Hence, also a change in the properties, including the stiffness, of the structure is calculated. Then, a further change in the stresses and strains is calculated on the basis of the change in these properties to determine a new adapted hysteresis branch. Then, a further change in the stress along a further portion of the adapted hysteresis branch is calculated as a function of a further change in the load in time. At the end of the process, the structure is manufactured accordingly.

129	Trigger circuit for low-power structural health monitoring system	US12844735	2010-07-27	US08401804B2	2013-03-19	Chang Zhang
A trigger circuit for use with a structural health monitoring system. To save power, a structural health monitoring system is programmed with a sleep mode and a wake, or operational, mode. In its operational mode, the structural health monitoring system can perform its usual tasks, e.g. monitoring a structure and determining its structural health. In sleep mode, many functions are suspended, so that the system requires less power. The trigger circuit wakes the system when the sensors of the structural health monitoring system emit a sufficiently large signal, i.e. when an event occurs. That is, when not in use, the system enters sleep mode, and when some event occurs (e.g., impact, or some other stresses that are of concern), the trigger circuit alerts the system, prompting it to shift from sleep mode to operational mode and to begin taking/analyzing data.
130	Method And System For Time Synchronization Of Phase Of Signals From Respective Measurement Devices	US13618439	2012-09-14	US20130018620A1	2013-01-17	Sylvain Riendeau; François Léonard; Patrick Picher; Michel Gauvin; Hugo Bertrand; Louis Dupont
According to the invention, a time synchronization of phase between measurement devices that do not share a same clock for their respective sampling of the signals is carried out by a time tagging of samples of the signals in time blocks followed by an adjustment of the phase values of components of interest of the signals in the regrouped time blocks so that the values refer to common time references between the measurement devices. The tagging is carried out with a synchronization signal available to the measurement devices, completed with count values provided by a counter operated by a reference clock for each measurement device.

132	Structural health monitoring system having memory on structure	US12432668	2009-04-29	US08244486B2	2012-08-14	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.

The present invention relates to a structural health monitoring system, for example a system used in the non-destructive evaluation of an aircraft structure. The present invention provides a method and apparatus for evaluating one or more anomalies within a structure using a structural health monitoring system that includes at least three transducers arranged in operative contact with the structure such that no two transducers are aligned to be parallel. A transducer excites an elastic wave that propagates through the structure, and reflections from any anomalies within the structure are collected by the three transducers. These collected signals are analysed to identify an anomaly within the structure. Time of flight techniques are used to determine the location of the anomaly.
134	IDENTIFICATION OF LOADS ACTING ON AN OBJECT	US13262450	2010-04-01	US20120031193A1	2012-02-09	Douglas E. Adams; Nick A. Stites; Nathanael C. Yoder; Jonathan R. White
Structural health monitoring systems can be limited to a minimum number of sensors due to cost, complexity, and weight restrictions. Some embodiments described herein pertain to a load and damage identification techniques that utilize one sensor. Several passive force estimation techniques are presented. Some techniques use either the shape or the amplitude of the magnitude of the applied force in the frequency domain. Several techniques iteratively reduce an underdetermined set of equations of motion into many overdetermined systems of equations to solve for the force estimates. The techniques are shown to locate and quantify impulsive impacts with over 97% accuracy and non-impulsive impacts with at least 87% accuracy. Impacts not acting at a specific input degree of freedom are also accurately located depending on the distance away from the modeled input degrees of freedom, and damaging impact forces are quantified by making assumptions about the impulsive nature of the applied force.
