Abstract: Systems and methods can be used for analyzing image data to determine an amount of vibration and/or misalignment in an object under analysis. In some instances, as operating equipment heats up during operation, temperature changes of various portions of the operating equipment leads to changes in dimensions of such portions, leading to misalignment. Multiple sets of data representative of the operating equipment in multiple operating conditions can be used to determine an amount of misalignment due to thermal offsets. Hot and cold temperatures of the equipment can be used to calculate thermal growth of various portions of the equipment, which can be used to determine an amount a misalignment due to thermal offsets. Additionally or alternatively, image data representing the equipment can be used to observe changes in alignment between states.

Abstract: An acoustic analysis system includes an acoustic sensor array that receives acoustic signals from a target scene and outputs acoustic data based on the received acoustic signals. A processor receives a plurality of acoustic data sets from the acoustic sensor array, representative of the target scene at different points in time. The processor determines one or more locations within the target scene represented by the plurality of acoustic data sets, each being a location of an acoustic signal emitted from the target scene. For each acoustic signal, the processor classifies the acoustic signal as an intermittent acoustic signal or a continuous acoustic signal, generates accumulated-time acoustic image data based on the plurality of acoustic data sets, and generates an accumulated-time display image for presentation on a display. Within the accumulated-time display image, acoustic signals classified as intermittent acoustic signals are distinguished from acoustic signals classified as continuous acoustic signals.

Abstract: Methods and apparatuses that utilize machine learning techniques to identify maintenance assets using sets of machine-health diagnostic images and link individual machine-health diagnostic images to the identified maintenance assets are described. The sets of machine-health diagnostic images may include a set of thermal images, a set of visible-light images, and/or a set of acoustic images. An identified maintenance asset may comprise an individual machine associated with a unique asset identifier. A diagnostic image linking system may acquire machine-health diagnostic images, apply object detection and other computer vision techniques to identify a particular machine within the machine-health diagnostic images, determine machine properties for the particular machine, generate a feature vector using the machine properties, select machine learning models corresponding with maintenance assets, generate predicted answers using the machine learning models, and generate an asset identifier for the particular machine based on the predicted answers.

Abstract: Systems and methods directed toward acoustic analysis can include an acoustic sensor array comprising a plurality of acoustic sensor elements, an electromagnetic imaging tool, and a processor in communication with the acoustic sensor array and the electromagnetic imaging tool. The processor can be configured to analyze acoustic data to extract one or more acoustic parameters representative of acoustic signals at one or more locations in an acoustic scene and generate a display image that includes electromagnetic image data and acoustic image data. The display image can further include information indicative of the one or more acoustic parameters at one or more locations in the acoustic scene, such as including acoustic image data in the display image at locations in the scene at which the one or more acoustic parameters satisfies a predetermined condition.

Abstract: Some systems include an acoustic sensor array configured to receive acoustic signals, an electromagnetic imaging tool configured to receive electromagnetic radiation, a position sensor configured to output position information, memory, and a processor. The processor can receive acoustic data from the acoustic sensor array and generate acoustic image data from the received acoustic data. The processor can receive electromagnetic image data from the electromagnetic imaging tool and combine the generated acoustic image data and the received electromagnetic image data to generate a display image. The processor can receive position information from the position sensor, and save the display image in memory associated with the received position information. Position information can be stored in metadata of the display image or displayed within the display image. The processor can be configured to link images stored in memory, such as based on position information associated with such images.

Abstract: Tools used to detect underlying structures, such as behind the surface of a wall, can include a first sensor, such as an electromagnetic sensor, configured to generate data indicative of the location of the underlying structure. Tools can include an indicator that provides an indication to a user based on the data. Tools can additionally or alternatively include an infrared imaging device for generating infrared image data indicative of the heat pattern of a scene. A display can display the generated infrared image data. Underlying structures may be visible in the heat pattern of the scene. The tool can indicate the presence of an underlying structure feature to an operator via one or both of the display and the indicator.
