Abstract: A method and system method for estimating fatigue damage in a structure obtains fatigue damage data collected using at least one sensor associated with the structure during at least one test operation and also obtains structure use parameter data collected during the at least one test operation. The obtained fatigue data and the obtained use parameter data are used to compute coefficients of at least one generic polynomial function that outputs a fatigue damage value based on inputs representing use parameter data. The at least one generic polynomial function is used to output an estimated fatigue damage value based on inputs representing use parameter data collected during use of the structure.

Abstract: Systems, apparatus and methods are provided for measuring moving vehicle information. Moving vehicle information may be measured by a sensor configured to respond to one or more wheels of the moving vehicle, where one or more of the wheels change the characteristic impedance of the sensor at the wheel's contact location. An electrical time domain reflectometry signal processing system which is capable of measuring the change in the impedance of the sensor and converting the impedance change to a signal may be connected operatively to the sensor. A data-processing system receives the signal and extracts the moving vehicle information therefrom.

Abstract: The mechanical load on a rolling element bearing is determined from the deformation of the rolling element bearing. The local deformation caused by the rolling contact forces is used to determine an average contribution to the mechanical load in order to average out the effect on the deformation as a result of the spread in diameter of the rolling elements of the bearing. The global deformation of the rolling element bearing is determined to calculate a dynamic contribution to the mechanical load. The dynamic contribution takes into account the variations of the mechanical load on the relevant time-scales that have been omitted from the average contribution as a result of the averaging operation. The total mechanical load is the sum of the average contribution and the dynamic contribution.

Abstract: The present invention is to provide an imperceptible motion sensing device, which includes a non-conductive elastomer made of a pliable and elastic non-conductor (e.g., polyurethane) and having a bumpy side formed with at least one sunken portion thereon, at least one conductive fiber positioned in the at least one sunken portion respectively (e.g., by sewing), and a conductive elastomer made of a pliable and elastic conductor (e.g., a conductive foam or conductive rubber) and provided on the bumpy side of the non-conductive elastomer. When the sensing device is compressed by an external force, corresponding portions of the conductive elastomer and the non-conductive elastomer are compressed and deformed, causing contact and hence electrical connection between the conductive elastomer and the at least one conductive fiber. Thus, the imperceptible motion sensing device not only provides more accurate and more sensitive signal detection, but also ensures consistent performance even after long-term use.

Abstract: A bending sensor includes a high resistance layer; a low resistance layer having a crack and a lower electrical resistance than the high resistance layer in a state where the crack is closed; an insulating layer between the high and low resistance layers; and a plurality of electrode portions connecting electrically in parallel the high resistance and low resistance layers. In an OFF state where a bend amount is small, the crack is unlikely to open and a combined resistance of electrical resistances of the high resistance layer and the low resistance layer is output as OFF resistance from the plurality of electrode portions. In an ON state where the bend amount is large, the crack is likely to open and at least the electrical resistance of the high resistance layer is output as ON resistance higher than the OFF resistance from the plurality of electrode portions.

Abstract: A method of designing and manufacturing apparatus. The method comprises: creating a design space; analysing expected loads acting on the design space to calculate a first load path within the design space; analysing expected loads acting on the design space when the apparatus is in a damaged state to calculate a second load path within the design space; selecting a region of the second load path which falls outside the first load path; and creating a final design which includes: a primary structure falling within the first load path; and a damage indication feature falling within the selected region. The damage indication feature is designed to provide a visual indication when the load transmitted by the damage indication feature exceeds a threshold.The load generates a stress in the primary structure which exceeds the stress in the damage indication feature until the primary structure becomes damaged, at which point the load generates a stress in the damage indication feature which exceeds the stress in the primary structure.
