摘要： Methods and systems are provided for condition-based maintenance of a structural component exhibiting a physical defect. One exemplary system comprises a measurement system to obtain a current measurement of a defect in a structure, a monitoring system, and a maintenance system. The monitoring system determines a probabilistic representation of degradation development data for the defect using the current measurement, determines a reference remaining usage life metric for the structure based on the probabilistic representation and a target probability value, and determines one or more remaining usage life bounds based at least in part on the reference remaining usage life metric. The maintenance system determines maintenance schedule or other remedial action(s) for the structure in a manner that is influenced by the reference remaining usage life metric and the one or more remaining usage life bounds.

摘要： A method for estimating stress of an electronic component. An electronic component including first and second elements and conductive bumps is provided. Each conductive bump has two surfaces connected to the first and second elements respectively. Two adjacent conductive bumps have a pitch therebetween. The conductive bumps includes a first conductive bump and second conductive bumps. A stress value of the first conductive bump related to a testing parameter is calculated. A stress value of each second conductive bump related to the testing parameter is calculated according to a first calculating formula. The first calculating formula is σ 2 = L D - 2 r σ 1 , σ2 is the stress of each second conductive bump, L is a beeline distance between each second conductive bump and the first conductive bump, D is an average value of the pitches of the conductive bumps, r is a radius of each surface, and σ1 is the stress value of the first conductive bump.

摘要： A belt drive and a method for the monitoring thereof allows conclusions to be drawn regarding loads to which the belt has been subjected over its past usage period. The method includes a rotatably mounted disc and a belt which is deflected at the disc. The belt and the disc are equipped with a marking and are positioned with respect to each other such that the markings are directly opposite each other in a trigger position when the belt circulates around the disc. The trigger position is recorded by a monitoring device, which emits a signal when the markings are located in the trigger position. The number of signals triggered over a time period is recorded. The loads to which the belt or the disc have been subjected during the time period is determined while taking into consideration relevant influencing variables.

摘要： Erosion sensors and systems, methods, and computer products thereof are operative to determine and provide real time erosion data. Such data may be used to determine in real time an amount of erosion or ablation on an ablative surface, for instance, of a rocket or missile launch pad, of an exhaust management system, of an extraterrestrial vehicle, or of a fire detection system.

摘要： A method and apparatus for identifying a health status of a contactor includes a processor coupled to a computer readable media. The processor is coupled to the contactor to instruct the contactor to open and close. A database stored in the computer readable media includes operation count variables for the contactor, closing time variables for the contactor, and health status rules for the contactor. The operation count variables and the closing time variables may be inputs to the health status rules to identify the health status of the contactor. A customization program may also be stored in the computer readable media. The customization program enables an operator to modify at least one of the operation count variables, the closing time variables, and the health status rules to affect the identified health status of the contactor.

摘要： A system and method for determining a condition of a filter filtering fuel associated with an engine. Input information relating to the operation of the engine is provided by a plurality of sensors. At least some of the input information is used to determine a plurality of input variables, the plurality of input variables representing a plurality of engine operating conditions including engine run time, engine torque and engine speed. An algorithm incorporating the input variables is used to determine the condition of the filter. Information concerning the condition of the filter may be output to a user such as an operator or service provider.

摘要： Generally, a system and method consistent with the present disclosure may provide a relatively low cost, relatively robust data acquisition and analysis system useful for condition-based maintenance. The system may be useful for condition-based maintenance in industrial applications, e.g., of equipment and/or machinery. The industrial monitoring system may be used, for example, to monitor a condition of rotating machinery, e.g., a wind turbine. The system and method may include data analysis that may be useful for anticipating a need for maintenance, repair and/or replacement of one or more components.

摘要： Methods are provided for designing a blending component for making a plurality of lubricant products that contain the designed blending component. This can be accomplished by first determining a plurality of manufacturability index values for each desired lubricant product for a family of proposed blending components. The manufacturing index values can then be used to construct a manufacturability window for each lubricant product. The manufacturability windows for each lubricant product can then be analyzed to determine regions of overlap, if any, where a proposed blending component can be used with an increased likelihood to formulate each of the desired products. Alternatively, manufacturability windows can be used to determine suitability of pre-existing blending components for formulation of desired products.

摘要： The invention relates to the fitness check of value documents. For at least two fitness criteria there is respectively determined with the aid of an unfit function an unfit degree of the particular value document. The unfit function clearly assigns an unfit degree to the fitness measurement values and has two threshold values, beyond which the unfit degree with respect to the relevant fitness criterion is 0 or 1. Between the threshold values there is an uncertainty range in which the unfit degree is, with respect to the relevant fitness criterion, between 0 and 1 and the unfit function behaves monotonously dropping or monotonously rising. Subsequently, the unfit degrees of different fitness criteria are combined into an unfit probability of the particular value document and on the basis of the unfit probability a fitness classification of the particular value document is carried out.
