  • Patent number: 12270733
    Abstract: A vibration data collection device monitors vibration of a machine, generates original machine vibration waveform data based on the monitored vibration, and removes portions of the original machine vibration waveform data that do not indicate an occurrence of a vibration event related to a potential fault in the machine. The vibration data collection device then stores thinned waveform data that includes blocks of the original machine vibration waveform data and excludes the portions that have been removed. A data analysis computer generates a thinned waveform plot based on the thinned waveform data. In some embodiments, the thinned waveform plot includes the blocks of original machine vibration waveform data separated in time by gaps representing the portions that have been removed.

  • Patent number: 12259435
    Abstract: A battery management system and method for performing a battery state and, optionally, health parameter observation is disclosed, in particular, cell state-of-charge (SOC) observation, with two redundant, independent and dissimilar lanes. Specifically, a SOC determination in a first one of the lanes is based on Coulomb Counting. The other lane employs a different algorithm than Coulomb Counting. In some embodiments, a battery health observation is further performed independently by the two lanes, wherein the first lane employs an aging model and the other lane a different (dissimilar) algorithm. On the basis of state and health observation, state (state of function) of the battery system can be predicted to determine a range of flight in accordance with a predetermined flight profile.

  • Patent number: 12241362
    Abstract: Provided are methods of locating a well bore to optimize fluid extraction from a region of interest. In this manner, well production may be better predicted without having to go through the time and effort of drilling exploratory-type wells. The methods analyze semblance values of voxels within a full activity volume, and identify near well activity (NWA) voxels based on voxels that exceed the mean semblance value by a cut-off value. For example, the cut-off value may correspond to one or two standard deviations greater than the mean semblance value. Optimal fluid recovery corresponds to a well bore location at or near the putative location corresponding to the maximum number of NWA voxels in the region of interest.
