Machine learning algorithms are used to determine an amount of material to be removed from one or more damage locations and determine an amount of material addition to the damaged portion(s) and/or at other locations on the blade to keep the natural frequencies of the repaired blade within design limits during operation.

Abstract: The present invention comprises a valve assembly with an unbalanced seal between sealing components of the valve assembly. For a gate valve assembly, an upstream seat may have a different outer diameter than a downstream seat, thereby creating an unbalanced seal with the gate. By increasing the sealing surface of the downstream gate/seat interface and by decreasing the sealing surface of the upstream gate/seat interface, the gate/seat interface may seal at lower pressures. A bidirectional seal is also disclosed that may prevent grease or sand from entering a cavity of the seat/pocket insert interface and assists with controlling the pressures and torque on the valve assembly.

Abstract: Disclosed are a wallet system and a transaction method. The wallet system includes a communication node, a scheduling node, and at least one backup node, where each node stores one private key, and all the private keys are for a same account. First, the communication node generates a transaction request based on received payment transaction information and sends the transaction request to the scheduling node. Next, the scheduling node selects a plurality of nodes as signature nodes in response to the transaction request, and after scheduling private keys of the signature nodes to sign a payment transaction one by one, the scheduling node generates signature success information and feeds the signature success information back to the communication node. Finally, the communication node performs a payment transaction operation after receiving the signature success information.

Abstract: An automated camera system and method are provided that are configured to search for an object emitting or reflecting a certain wavelength of light. The camera can be infrared, electro-optical, or otherwise. Image processing software is configured to isolate pixel groups in each image, wherein those pixel groups fit a wavelength or color patterns of an object being searched. The system also includes processing methods for determining the relative location of the object (GPS or other) based upon the location of the camera and the field of view of the camera. Materials can also be used to tag the object so that the object is easier to find in adverse lighting conditions. Alternatively, the tag can be a wavelength that only one group of searchers knows about, and hence the object can remain relatively hidden from others. The system can be readily mounted in an aircraft or other vehicle so that large areas can be scanned and searched.

Abstract: The present invention includes systems and methods for continuous fracturing operations across a multichannel fracturing configuration. To swap a first well for a second well while continuously pumping water and/or frac fluid through the fracturing system, the second well may be initially prepared through a pressure equalization process. Once the second well is equalized and open, the first well may be sequentially closed and depressurized. Thus, the first well is swapped for the second well while the water and/or frac fluid continuously flows through the system. A conditional flow control valve may be used to sequentially open and/or close the flow of frac fluid through the frac manifold.

The system includes a receiver clock having a clock bias and a clock drift relative to a reference clock and may also include a motion sensor. A decoder receives transmitted signals from a number of transmitters and determine pseudo-ranges and transmitter frequencies therefrom and a processing unit receives the pseudo-ranges, the transmitter frequencies and the receiver velocity and determines the position of the receiver therefrom. When only two transmitters are available, the position of the receiver is determined dependent upon a known receiver clock drift. The system may also determine clock bias and, when three or more transmitters are available, receiver clock drift. The processing unit uses ranging and Doppler equations in combination, and may also use a measured velocity.
