  • Patent number: 11054292
    Abstract: A dry-particulate monitoring system for a machine that distributes dry-particulate to the ground by metering product into a flowing airstream. The airstream is diverted into several tubes mounted on booms covering some horizontal distance. At the end of each tube is a deflector designed to direct the flow of material to a desired location with a particular coverage. An acoustic-based sensor of the preferred embodiment is placed on each deflector to detect material flowing through each tube or pipe or against the deflector. The information that is gathered from the sensors is sent to the dry-particulate spreader operator, who is able to view the real time operation of the dry-particulate flow. The system may be capable of detecting presence or absence of flow (i.e., blockage), or may detect variance of flow in individual pipes over time, or variances of flow between different pipes.

  • Patent number: 11035714
    Abstract: Provided is a flow meter capable of logging data more reliably. In this operation, a detection element repeatedly detects a physical quantity related to a flow rate of a fluid flowing in a pipe in a predetermined sampling cycle. Based on physical quantities, a calculation part sequentially calculates the flow rate of the fluid in the pipe. Further, a time measurement part calculates the time. A control storage part is caused to store a logging target, a logging cycle, and logging start definition information. Based on the logging start definition information, a control part automatically starts logging of the logging target in response to startup of the flow meter, and causes a log storage part to store the time measured by the time measurement part and a numerical value of the logging target in association with each other in every logging cycle.

  • Patent number: 11002618
    Abstract: An assessment system and method are described that capture indoor temperature measurements and corresponding outdoor temperature measurements in order to determine a thermal efficiency of a structure. The assessment system identifies quiescent periods and trims these periods to eliminate undesirable influences such as auxiliary heating or solar gain. The quiescent periods are then compared to outdoor temperature differences to determine the thermal efficiency of the structure. The system can model the structure's performance metrics, through inferred qualitative and quantitative characterizations including, but not limited to, the building's rate of temperature change as a function of internal and external temperatures, the building's heating, cooling, and other energy needs as they relate to the building envelope, appliances, and other products used at the site and occupant behavior.

  • Patent number: 11002641
    Abstract: A statistical method is used to separate periodic from non-periodic vibration peaks in autocorrelation spectra. Generally, an autocorrelation spectrum is not normally distributed because the amplitudes of periodic peaks are significantly large and random relative to the generally Gaussian noise. In a normally distributed signal, the statistical parameter kurtosis has a value of 3. The method sequentially removes each largest amplitude peak from the peaks in the spectrum until the kurtosis is 3 or less. The removed peaks, which are all considered to be periodic, are placed into a set. The total energy of the peaks in the set is considered to be the total periodic energy of the spectrum. As the process of building the peak set proceeds, if its total energy becomes greater than or equal to a predefined energy threshold before its kurtosis reaches 3 or less, the process stops and the periodic peak set is defined.

  • Patent number: 10948471
    Abstract: In some embodiments, data from multiple vehicle-based natural gas leak detection survey runs are used by computer-implemented machine learning systems to generate a list of natural gas leaks ranked by hazard level. A risk model embodies training data having known hazard levels, and is used to classify newly-discovered leaks. Hazard levels may be expressed by continuous variables, and/or probabilities that a given leak fits within a predefined category of hazard (e.g. Grades 1-3). Each leak is represented by a cluster of leak indications (peaks) originating from a common leak sources. Hazard-predictive features may include maximum, minimum, mean, and/or median CH4/amplitude of aggregated leak indications; estimated leak flow rate, determined from an average of leak indications in a cluster; likelihood of leak being natural gas based on other indicator data (e.g. ethane concentration); probability the leak was detected on a given pass; and estimated distance to leak source.
