  • Publication number: 20250021999
    Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed to determine unique audience size via clustered data. An example apparatus includes memory, machine readable instructions, and processor circuitry to at least one of execute or instantiate the machine readable instructions. The example processor circuitry is to form a first matrix identifying matching and non-matching instances of first values of respective demographics of an audience of media and second values of the respective demographics. Also, the processor circuitry is to normalize the first matrix to generate an account sharing adjustment matrix. Additionally, the processor circuitry is to apply the account sharing adjustment matrix to a vector of one or more counts of impressions of the media to correct for one or more members of the audience that share a user account registered with a database proprietor, the one or more counts of the impressions corresponding to the respective demographics.

  • Publication number: 20240258950
    Abstract: A digital power converter arrangement of an electric vehicle includes a CPU circuit and a function selection circuit. The CPU circuit is configured to execute and perform analog and digital conversion, pulse-width modulation and communication, including a CPU outputting one or more PWM signals by changing a time ratio of a turn-on/turn-off of square wave pulse width modulation signals. The function selection circuit includes a function selector switch configured to switch between an external battery charging function mode, an AC power supply output function mode, and an external motor driver function mode, and a motor selector switch configured to function a motor hall mode when the function selector switch is switched to the external motor driver function mode, wherein the CPU detects the function selector switch and motor selector switch to switch states to run corresponding functions.

  • Publication number: 20240229636
    Abstract: A system can receive data relating to a tubular of a well system. The system can execute a first module to determine first outputs. The system can execute a second module to determine second outputs based on the first outputs. The system can execute a third module to determine third outputs based on the first outputs. The second outputs can include a crack-initiation fracture pressure, and the third outputs can include a crack-propagation fracture pressure. The system can identify a brittle-burst strength of the tubular from among the second outputs, the third outputs, and a standard burst strength of the tubular. The system can provide the brittle-burst strength of the tubular to facilitate an adjustment to the tubular to optimize a wellbore operation associated with the well system.

  • Publication number: 20240102376
    Abstract: A system can generate, via a software model, downhole pressure estimations and downhole debris estimations using caving parameters. Additionally, the system can generate, via the software model, settled caving volume percent estimations using the caving parameters. The system can determine a pack off volume percent using the downhole pressure estimations, the downhole debris estimations, and the settled caving volume percent estimations. The system can output, via a user interface, the pack off indicator and a subset of the caving parameters for use in adjusting a wellbore operation. The user interface can provide a plot of the pack off volume percent horizontally offset with respect to a plot of the subset of the caving parameters and a depth of the wellbore.

  • Patent number: 11938041
    Abstract: The present disclosure relates to the technical field of medical instrument and provides a passage establishment device for posterior spinal fusion minimally invasive surgery. The device includes: a tube, an interior of the tube includes a through hole penetrating through both axial ends of the tube, and a wall of the tube includes an opening portion. The tube of the passage establishment device of the present disclosure can be inserted between the vertebral bodies and can also be removed from between the vertebral bodies. The through hole of the tube forms a surgical passage for the fusion device to penetrate, which can safely protect human tissues and is convenient for doctors to perform follow-up operations. The tube can be installed quickly, and thus the operation time is shortened. It is easy to disassemble, clean, and disinfect the tube.
