The control unit based on a stored program or an external command activates the actuators to place the source and the sensor devices attached to the two arms of the actuators on the two sides of the filter membrane. The sensor measures the light intensity transmitted through the filter. The control unit upon receiving the intensity data determines the filter blockage level and communicates alert to the user when the blockage exceeds a predetermined value. The system uses a 4G or a 5G IoT network capability for data collection and communication with servers and user devices.

  • Patent number: 11221291
    Abstract: Methods for quantitatively determining the time (TNI) between (1) the application of this method and (2) the time at which the next out-of-service API 653 internal inspection of a steel, field-erected, aboveground storage tank (AST) containing petroleum/water products should be performed. These methods combine four in-service measurements of the thickness, integrity, and corrosion rate of the tank bottom with an empirical corrosion rate cumulative frequency distribution (CFD) for the tank of interest to develop a Bayesian tank bottom survival probability distribution to determine TNI. During this entire TNI time period, the risk of tank bottom failure is less than at the time these methods were applied. If available, the results of a previous out-of-service API 653 internal inspection are also used. These methods can be applied at any time while the tank is in-service to update the internal inspection interval previously determined in an out-of-service internal inspection of the tank.

  • Patent number: 11188065
    Abstract: Techniques, including systems and methods for monitoring a rotating equipment, are provided. A sensor that is in proximity of the rotating equipment senses vibrations of the rotating equipment. The sensor generates a digital signal corresponding to the vibrations of the rotating equipment and transmits the digital signal over a communication network. A server receives the digital signal and pre-processes the digital signal using ensemble empirical mean decomposition (EEMD) technique. The server processes the digital signal using wavelet neural network (WNN) to detect faults in the rotating equipment. Further, the server processes the digital signal using the wavelet neural network to predict remaining useful life (RUL) of the rotating equipment.

  • Patent number: 11120644
    Abstract: A client computing system (CCS) receives a tool measurement from a measurement tool other than by determining the tool measurement from a vehicle data (VD) message. The CCS generates a VD report including a vehicle identifier of a vehicle associated with the tool measurement and the VD report. The VD report can include temporal and/or spatial identifiers pertaining to the tool measurement. The VD report can be provided to a server computing system (SCS) for storage as part of a VD record associated with the vehicle. The CCS that generated the VD report or another CCS can request the VD report from the SCS. The SCS can determine if the requesting CCS is authorized to receive the VD report to maintain the vehicle owner's privacy. The tool measurement can be selected from a service procedure provided to the CCS from SCS and displayed at the CCS.
