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.

An apparatus and a method for evaluating film adhesion are disclosed. The film is disposed on a first substrate, a side of the first substrate provided with the film is attached to a second substrate, and the film is divided into units. The apparatus includes an evaluation machine, which includes an upper fixing mechanism and a lower fixing mechanism disposed opposite to each other, the second substrate is detachably fixed on the upper fixing mechanism, and a side of the first substrate not provided with the film is detachably fixed on the lower fixing mechanism. The evaluation machine further includes a force application device, which is configured to apply an external force to the upper fixing mechanism and/or the lower fixing mechanism, so that the upper fixing mechanism and the lower fixing mechanism generate relative movement away from each other.

A method includes receiving, by a first wireless device integrated into a management facility from a second wireless device integrated into a detection device, environmental conditions produced by a structure and detected by the detection device attached to the structure; and processing, by the management facility, the environmental conditions to detect a deviation from an expected operation of the structure.

An aircraft includes first and second gas turbine engines having a first component and a second component that is redundant with the first component, and an engine health monitoring system (EHMS) coupled to the first and second gas turbine engines. The EHMS is configured to calculate a remaining useful life (RUL) of the first component and of the second component, calculate a rate-of-life consumption of the first component and of the second component, predict when failure of the first component and failure of the second component will occur based on the RUL of each and based on the respective rate-of-life consumption of each, and provide instructions for altering operation of the aircraft that affects the RUL of the first or second component.

Systems and methods for analyzing tire tread data to assess tire tread parameters, such as irregular wear characteristics of a tire tread, are provided. More particularly, an automated and robust flattening process c be performed to transform tire tread data, such as a tread surface map, into flattened tire tread data. The flattened tire tread data can provide tread heights defined in a measurement direction that is normal to the surface of the tire tread, as opposed to parallel to a radial axis of the tire. The flattened tread data can be analyzed to assess one or more parameters of the tread of the tire. For instance, local height indicators for the flattened tread data can be determined using a local maximum as a reference. Because the local height indicators are relative heights determined from a local maximum, quantification of tread depth can be more easily obtained.

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.

The invention relates to improved systems and methods for inspecting the tubes of a steam generator of a nuclear reactor that involves modeling the steam generator, comparing signals of a tube from an eddy current sensor with aspects of the model to determine whether further analysis is required, employing primary and secondary analysis processes, and producing a combined report of the primary and secondary analysis results.

The present invention provides a pipeline management supporting server capable of unifying management of attribute data of a pipe component and location information on a pipe network, efficiently detecting an abnormality of a pipeline remotely, and diagnosing the degradation state of the pipeline. The pipeline management supporting server (1) of the present invention includes: a private data processing unit (11) and a statistical calculation processing unit (12). The private data processing unit (11) includes an event data acquisition section (114) that acquires event data of a pipeline measured by a sensor(s), a measured event data storage section (112) that stores the event data of the pipeline, a pipeline database data storage section (111) that stores pipeline database data, a possible abnormality detection section (113), and an information output section (115). The possible abnormality detection section (113) identifies a pipeline and a location pertaining to the acquired event data of the pipeline with reference to the pipeline database data stored in the pipeline database data storage section (111) and generates possible abnormality detection information on the acquired event data of the pipeline. The statistical calculation processing unit (12) includes a data analysis section (122) and a statistical calculation data storage section (121) that stores statistical calculation data. The data analysis section (122) prepares, from event data of plural pipelines each having the same attribute as the pipeline pertaining to the event data acquired by the private data processing unit (11), an aging characteristic graph of the plural pipelines. The statistical calculation data storage section (121) stores the aging characteristic graph prepared by the data analysis section (122). The data analysis section (122) further generates degradation state diagnostic information on the pipeline by checking the pipeline pertaining to the event data acquired by the private data processing unit (11) against the aging characteristic graph. The information output section (115) of the private processing unit (11) outputs the degradation state diagnostic information and abnormality determination result detection information that is generated by examining the possible abnormality detection information and the degradation state diagnostic information in comparison.
