    Abstract: A hydraulic fracturing machine includes a pump failure detection system. The hydraulic fracturing machine includes a hydraulic fracturing pump with a power end and a fluid end. The power end includes a plurality of roller bearings, and the fluid end includes a flow of fluid. A particle sensor coupled to the power end is configured to transmit particle information regarding a quantity of particles in the fluid. A temperature sensor, also coupled to the power end, is configured to transmit temperature information regarding a temperature of the fluid. A vibration sensor coupled to the power end is configured to transmit vibration information regarding a vibration of each of the plurality of roller bearings. An electronic control module analyzes the particle information, the temperature information and the vibration information, and calculates a failure warning level based on the analysis.

  • Patent number: 10827423
    Abstract: Systems, methods, and processing nodes for communicating using at least two different radio access technologies (RATs) include determining whether or not an access node is capable of communicating using the at least two RATs (e.g. using 4G LTE and 5G NR, also known as 5G EN-DC), and instructing the access node to broadcast an indicator, wherein receiving the indicator, a wireless device can attach to both first and second RATs. The wireless device is further instructed to prioritize which combination of RATs to attach to based on a signal level transmitting using each RAT.

  • Patent number: 10484766
    Abstract: Disclosed in the present invention is a speaker module. The speaker module comprises a housing, and a speaker unit located within the inner chamber of the housing. The speaker unit separates the inner chamber into a front sound chamber and a rear sound chamber which are isolated from each other. The housing is embedded with a metal sheet, the metal sheet being provided with a pressure relief hole which is acoustically sealed and used for communicating a rear sound chamber and the external environment. The pressure relief hole is provided with a mesh on the side away from the rear sound chamber. The speaker module provided by the present invention has a housing embedded with a metal sheet, the metal sheet being provided with a pressure relief hole. The inner diameter of the pressure relief hole can be made small according to actual needs.
