Abstract: Changing a cumulative pumping rate of multiple pump units by adjusting individual pumping rates of the pump units, wherein each temporary dip or spike of an individual pumping rate of one of the pump units is automatically offset by a predetermined temporary adjustment of an individual pumping rate of another one or more of the pump units to thereby reduce effects of the temporary dip or spike on the cumulative pumping rate of the pump units.

Abstract: A wellhead landing, locking and sealing detection system may receive an acoustic signal from at least one acoustic sensor located on an outer surface of a wellhead. A wellhead landing, locking and sealing detection system may process the acoustic signal resulting in a processed acoustic signal. Processing the acoustic signal may include normalizing the acoustic signal, smoothing the acoustic signal, and differentiating a background signal from the acoustic signal. A wellhead landing, locking and sealing detection system may select a portion of the processed acoustic signal. A wellhead landing, locking and sealing detection system may identify a reflection characterization, frequency or profile from the portion. A wellhead landing, locking and sealing detection system may, based on the reflection characterization, frequency or profile, identifying a landing, locking and sealing configuration of the equipment with the wellhead.

Abstract: An online system customizes documents for a particular context, user, or set of users. The online system receives an image of a physical document and extracts components, such as text, titles, items and their metadata, from the physical document. The online system may apply rules to the metadata for one or more items to determine whether to modify at least a portion of the metadata. The online system also applies a model to generate an affinity score for a context or a user and each component of the document. If the score for a component is below a threshold, the online system prompts a generative model to generate replacement content for the component. Subsequently, the online system applies the model to the generated replacement content and updates the document with the generated replacement content for the component if the score of the generated replacement content is higher.

Abstract: Aspects of the present invention relate to a support beam for a vehicle. The support beam is configured to structurally support a first suspension component and a second suspension component. The support beam includes a first mounting member configured for connection to the first suspension component at a first side of a vehicle; a second mounting member configured for connection to the second suspension component at a second side of a vehicle; and a housing portion configured to mount therein high voltage electrical components. The housing portion of the support beam is located between the first mounting member of the support beam and the second mounting member of the support beam.

Abstract: There is provided a control system (200), a vehicle (1), a method (500), and computer software, for controlling thermal energy capture of vehicle kinetic energy of a vehicle. The control system (200) is configured to determine whether to enter a first regenerative braking energy conversion mode or a second regenerative braking energy conversion mode. The control system is configured to output a control signal (508, 510) to cause an electric machine (402, 404) of the vehicle to enter the first regenerative braking energy conversion mode or the second regenerative braking energy conversion mode in dependence on the determination. The first regenerative braking energy conversion mode is configured to provide a first proportion of total energy generated via the electric machine as thermal energy added to a cooling system (400) of the vehicle.
