  • Patent number: 10809717
    Abstract: Sensor management systems for computer assisted or autonomous driving vehicles are disclosed herein. A computer assisted or autonomous driving vehicle may be provided with a plurality of sensors and a sensor management system configured to predictively maintain effectiveness of the plurality of sensors, based at least in part on predicted cleaning needs of the sensors, predicted obstruction or destruction events of the sensors, or predicted environmental or operating conditions. In embodiments, the sensor management system may be coupled to a navigation system of the vehicle, and may, in response to a predicted sensor obstruction or destruction event, change a navigation parameter of the vehicle to avoid the event. Alternatively, if the predicted event is determined to be within an acceptable risk tolerance threshold, the sensor management system may follow an original navigational route but implement event avoidance actions. Other embodiments may be disclosed or claimed.

  • Patent number: 10753153
    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.

  • Patent number: 10738784
    Abstract: A method of operating an electric induction motor with a variable-speed drive includes determining a voltage level on a DC bus for the drive, and measuring a first magnitude of magnetic flux from a stator of the normally-operating electric motor, determining a normal flux level. The method includes disabling a first output to the drive when the DC bus voltage is less than a first threshold level. The method includes measuring a magnetic flux feedback signal having a phase and second magnitude, estimating a speed of the electric motor, and configuring a second output signal for the drive when the DC bus voltage is greater than a second threshold level. The second output signal matches a signal from the second magnitude and a phase of magnetic flux. The method includes enabling the drive output to restart the electric motor when the magnetic flux is greater than a third threshold value.
