Abstract: A transportation asset management solution is described. The transportation asset can be evaluated for operability. The evaluation can include periodic analysis of defect data acquired during operation of the transportation asset over a period of time. The evaluation can determine current operability of the transportation asset with respect to the defect and/or a future requirement for maintenance on the transportation asset due to the defect. One or more actions can be generated based on the analysis. A composite defect cost corresponding to the defect can be computed. The composite defect cost can include costs associated with one or more of: acquiring defect data during operation of the transportation asset, addressing the defect, a defect failure, and/or an error in identifying the defect. One or more aspects of the management solution can be periodically optimized to reduce the composite defect cost.

Abstract: A solution for monitoring a railway vehicle is provided. A vehicle node and one or more sensor nodes are deployed on the railway vehicle. Each sensor node is configured to acquire data and communicate with the vehicle node only when certain conditions are met. The sensor node(s) and vehicle node can evaluate operating conditions to determine whether an alert should be sent to initiate action. In an illustrative application, the alert can correspond to excessive hunting by a wheelset of the rail vehicle which is posing a danger for derailment.

Abstract: A solution for monitoring an area including one or more restricted zones is provided. The solution can include one or more monitoring assemblies deployed to acquire image data of the area and independently monitor operations within the area at each monitoring assembly. A monitoring assembly can include one or more local alert components to generate an audible or visual alarm to local personnel. Data regarding static features present in the area can be used to create a registration map of the field of view, which can subsequently enable accurate determination of the three-dimensional location of a target using two-dimensional image data and/or identify an extent of a restricted zone even when one or more of the static features are obscured. Monitoring a target over a series of images can be used to determine whether an alert condition is present.

Abstract: A solution for evaluating the condition of a vehicle component based on resonant response profiles across a set of bands of vibrations. The vibrations can be induced into the target component during normal operation of the target component. The resonant response profile of the vehicle component can vary depending on wear or damage, and thus can be used to determine whether the vehicle component can safely remain in use. An embodiment comprises an isolated segment of rail of a length selected to allow a single railroad wheel on it at a time, with a set of devices which can induce specific vibrations into the wheel as it passes, and another set of devices which can acquire the resonance signals from the wheel.

Abstract: A solution for pre-screening an object for further processing is provided. A pre-screening component can acquire image data of the object and process the image data to identify reference target(s) corresponding to the object, which are visible in the image data. Additionally, the pre-screening component can identify, using the reference target(s), the location of one or more components of the object. The pre-screening component can provide pre-screening data for use in further processing the object, which includes data corresponding to the set of reference targets and the location of the at least one component. A reference target can be, for example, an easily identifiable feature of the object and the component can be relevant for performing an operation on the object.
