Abstract: A technique for automated temperature monitoring relies on subject recognition in combination with contactless measurement of subject temperature at one or more measurement stations, with corresponding use of trend analysis. A multiplicity of advantages flow from the use of subject recognition and corresponding trend analysis, including more reliable detection of anomalous temperatures relative to trendlines determined for individual recognized subjects, with possible compensation for group trends, local environmental factors, variability in measuring equipment, etc.

Abstract: The present invention generally relates to assigning and reporting the cleanliness of objects and areas, and particularly relates to utilization of object and area cleanliness states as determined by the opposing processes of cleaning and dirtying detected through various methods to provide an indication of the state of cleanliness potentially utilized to alter the process of cleaning and/or dirtying to reach a desired state of cleanliness. Detection of the cleaning and dirtying operations can be performed automatically through image processing and behavior detection of still images/video indicating the activity taking place in the area of interest and time. The state of cleanliness can then be reported to interested parties as textual reports and/or augmented reality overlays on still images/video.

Abstract: A method can include receiving data characterizing a first property of an asset over a first time period. The method can also include receiving data characterizing user interaction with an interactive graphical object. The method can further include determining, by a predictive model, data characterizing the first property of the asset over a second time period. The determining can be based in part on the received data characterizing the user interaction. The method can also include rendering, in a graphical display space, one or more of a first plot of the received data characterizing the first property over the first time period and a second plot of the determined data characterizing the first property over the second time period.

Abstract: A method can include receiving data identifying an industrial asset. The method can also include receiving data characterizing one or more sensors configured to detect a first property of the asset. The method can further include determining a first graphical representation of the asset based on the received data identifying the industrial asset, and a second graphical representation of a first sensor of the one or more sensors based on the received data characterizing one or more properties of one or more sensors. The method can further include rendering, in a graphical display space, the first graphical representation and the second graphical representation. One or more visual properties of the second graphical representation can be indicative of one or more properties of the first sensor and/or the detected first property of the asset.

Abstract: Assemblies for an ultrasonic probe and manufacturing methods are presented. In one example, the method includes additively forming first portions of the assembly using a first material with first acoustic properties and second portions of the assembly using a second material with second acoustic properties, the first and second acoustic properties being configured to modify ultrasonic signals of the ultrasonic probe. In another aspect, a housing for an ultrasonic probe is presented. The housing includes additively-formed portions, a fluid channel, and at least one cavity. The first additively-formed portions include a first material with first acoustic properties. The second additively-formed portions include a second material with second acoustic properties. The first and second acoustic properties are configured to modify ultrasonic signals of the ultrasonic probe. The fluid channel is for receiving fluid within the housing of the ultrasonic probe.
