  • Patent number: 11736415
    Abstract: An external processing system includes a port configured to exchange signals with a router and one or more processors configured to instantiate an operating system and a hypervisor based on information provided by the router in response to the external processing system being connected to the router. The processors implement a user plane layer that generates feedback representative of a processing load and provides the feedback to the router via the port. The router includes a port allocated to an external processing system and a controller that provides the information representing the operating system and hypervisor in response to connection of the external processing system. The controller also receives feedback indicating a processing load at the external processing system. A queue holds packets prior to providing the packets to the external processing system. The controller discards one or more of the packets from the queue based on the feedback.

  • Patent number: 11708733
    Abstract: An electric driven hydraulic fracking system is disclosed. A pump configuration includes the single VFD, the single shaft electric motor, and the single hydraulic pump mounted on the single pump trailer. A controller associated with the single VFD and is mounted on the single pump trailer. The controller monitors operation parameters associated with an operation of the electric driven hydraulic fracking system as each component of the electric driven hydraulic fracking system operates to determine whether the operation parameters deviate beyond a corresponding operation parameter threshold. Each of the operation parameters provides an indicator as to an operation status of a corresponding component of the electric driven hydraulic fracking system. The controller initiates corrected actions when each operation parameter deviates beyond the corresponding operation threshold.

  • Patent number: 11668144
    Abstract: An electric driven hydraulic fracking system is disclosed. A pump configuration that includes the single VFD, the single shaft electric motor, and the single hydraulic pump that is mounted on the single pump trailer. A pump configuration includes a single VFD configuration, the single shaft electric motor, and the single shaft hydraulic pump mounted on the single pump trailer. The single VFD configuration converts the electric power at the power generation voltage level distributed from the power distribution trailer to a VFD voltage level and drives the single shaft electric motor to control the operation of the single shaft electric motor and the single hydraulic pump. The VFD voltage level is a voltage level that is required to drive the single shaft electric motor. The VFD configuration also controls operation of the auxiliary systems based on the electric power at the auxiliary voltage level.

  • Publication number: 20230160271
    Abstract: Certain embodiments of the present application relate to a variable frequency drive (VFD) cabin for a pump configuration including a mobile trailer on which the VFD cabin is to be mounted. The VFD cabin generally includes a medium-voltage VFD and a ventilation system. In certain embodiments, the ventilation system is configured to generate an overpressure condition within the cabin to discourage the entry of dust and debris into the cabin. In certain embodiments, one or more components of the medium-voltage VFD are coupled to the floor of the cabin via a vibration damping system. In certain embodiments, the VFD cabin may be directly coupled to a chassis of the mobile trailer without an intervening suspension being provided between the VFD cabin and the chassis.

  • Publication number: 20230046689
    Abstract: A system, non-transitory computer readable medium, and method include entering redundant oscillators and a cascaded oscillator of a spoofing resistant system into an initialization state. All but one of the redundant oscillators are disciplined to a time-and-frequency external input into normal disciplining state with the remaining one of the redundant oscillators in a holdover state. When all but one of the redundant oscillators have reached the normal disciplining state, placing all but one of the redundant oscillators into the holdover state, disciplining the remaining one of the redundant oscillators to the time and frequency external input, and disciplining the cascaded oscillator to one of the all but one of the redundant oscillators now in the holdover state. When the remaining one of the redundant oscillators and the cascaded oscillator have reached the normal disciplining state, transitioning from an initialization stage to a steady state management stage.

  • Publication number: 20230023487
    Abstract: A system wherein when a normal state is entered: discipline only one of at least three oscillators to an external reference; output frequency and time based on the other oscillators not being disciplined to the external reference; and monitor the output frequency difference of the one of the oscillators being disciplined and a composite value of the output frequency difference among the other oscillators. A spoofing state is identified when the monitored difference is more than a difference threshold. When the spoofing state is identified: reset the frequency and time of the oscillator in the spoofing state to match the composite value of the other oscillators; resume disciplining the oscillator in the spoofing state from the external reference after expiration of a time period; and clear the spoofing state and return to the normal state when the oscillators have the output frequency differences among the oscillators below the difference threshold.

    Abstract: A method, non-transitory computer readable medium, and device for correcting for one or more errors when using mobile network communication signals to augment navigation includes determining one or more pseudorange and range rate measurements for a computing device with respect to one or more cellular base stations. One or more of errors in the one or more pseudorange and range rate measurements are obtained which are determined based on previously received satellite positioning or time data. A current position or current time is determined based on the determined one or more pseudorange and range rate measurements and the one or more obtained errors when one of a plurality of states indicates current satellite positioning or timing data is unavailable. The determined current position or the determined current time for the computing device is provided.
