摘要： In one general aspect, a composite foam comprises a non-layered mixture of a polymeric foam with a plurality of voids; and a plurality of conductive fillers disposed in the polymeric foam. The conductive fillers are disposed in an even manner from outer surface to outer surface. In some implementations, the conductive fillers are up to 25% by weight of the composite foam. In some implementations, the composite foam may be used as padding. In some implementations, the composite foam may be used as a strain gauge. In some implementations, the foam may be in contact with a voltage detector.

摘要： 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.

摘要： An impact sensing laminate 2 has a first surface 211 on which an impact force acts; a second surface 222 brought in contact with a protection object OBJ; an impact absorption layer 21 and a first pressure-sensitive layer 22. When a direction heading for the second surface from the first surface is defined as a first direction, the first pressure-sensitive layer is in the first direction from the impact absorption layer. The first pressure-sensitive layer is a layer of sensing a first impact force as the impact force to have been attenuated by the impact absorption layer.

摘要： An electro-mechanical fuse is provided and includes a chassis component, an extrusion disposed on a monitored component which is disposable proximate to the chassis component and a sensor. The sensor is mounted to the chassis component. The sensor is mechanically breakable in power-on and power-off conditions by the extrusion as a result of a predefined action of or relative to the monitored component. The sensor electrically signals an occurrence of the mechanical breakage during power-on conditions following mechanical breakage.

摘要： 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.

摘要： A method for determining a break-away force in an actuator is provided, the actuator comprising an actuator armature including a positioning element movable in relation to the actuator housing. The positioning element is movable by means of an actuator drive such that a driving force is applied through the actuator drive to the positioning element. The actuator is in a resting state in the beginning, the driving energy required for moving the actuator drive is successively increased, wherein the driving energy is converted into a driving force by driving means, and a measurement value at the actuator drive is measured by at least one sensor, wherein as soon as a change of the measurement value is detected, a state is verified in which a holding force counteracts the movement of the position element.
