  • Patent number: 11898930
    Abstract: A method for processing vibration data includes receiving shaft displacement data, from a pair of sensors, including shaft center X-axis displacement and shaft center Y-axis displacement, which are orthogonal to each other. The method includes converting the shaft displacement data to shaft velocity data by calculating a difference in shaft displacement over time and/or converting into shaft acceleration data by calculating a different in shaft velocity over time. The shaft velocity or acceleration data is filtered, sorted and grouped into three or more groups, assigning a color to each velocity group or acceleration group. The method generates an image of a velocity or acceleration orbit plot, where the X-axis displacement and the Y-axis displacement define coordinate pairs of a trace of shaft center displacement, and the velocity or acceleration group between each coordinate pair defines a display color of the trace.

  • Patent number: 11868585
    Abstract: The systems and methods described herein are directed to resource monitoring and resource consumption analytics. Resource usage is tracked through a gateway device monitoring resources using remote input sensors, and usage data is transmitted to a central processing unit whereby the data is interpreted and compared with usage over time and site conditions such as weather. For example, incoming usage data is compared with resource signatures in a signature library representing an ideal usage or historical usage for given site condition. This data is interpreted into simple command displays with alerts, alarms, thereby reporting and alerting to an end-user via multiple delivery mechanisms, of potential sources of resource waste or loss. Further, the alerts or alarms can include easily interpreted recommendations to allow a non-skilled worker to take corrective procedures to maximize efficient use of the consumable resources.
