Publication number: 20260295802Abstract: A power tool has a directional switch interlock. The power tool includes a drive mechanism having an output shaft that is configured to rotate about a rotational axis in a clockwise direction or a counterclockwise direction. A directional switch is configured to select the rotational direction of the output shaft between the clockwise direction and the counterclockwise direction. A trigger member of the power tool is configured to be actuated from a non-actuated position to an actuated position to cause the drive mechanism to rotate the output shaft about the rotational axis. The trigger member includes a directional switch-locking member, where when the trigger member is actuated from the non-actuated position to the actuated position, the directional switch-locking member engages with the directional switch, locking the directional switch from changing the selected rotational direction of the output shaft.Type: ApplicationFiled: March 26, 2025Publication date: October 1, 2026Inventors: Kevin M Purdy, Justin T Chellew, Wei Dai

Patent number: 12747641Abstract: The invention relates to a downhole system incorporating an electromagnetic disconnect (EMD). The EMD features an actuator rod, a latch mechanism, and a magnetic solenoid, enabling controlled and selective electrical and/or mechanical disconnect of downhole tools. When activated by an electric current, the solenoid triggers the retraction of spring-loaded components, allowing the actuator rod to disengage from the latch. This allows the latch fingers to contract, and when coupled with an electrical connector interface, will disrupt the electrical continuity within the downhole system. Also, the finger contraction will allow for the mechanical disconnect, releasing the tool from the EMD. The mechanism is reusable, allowing for multiple cycles of engagement and disconnect. The system enhances operational efficiency and safety by providing precise control over tool deployment and retrieval in complex wellbore environments.Type: GrantFiled: November 15, 2024Date of Patent: September 29, 2026Assignee: Schlumberger Technology CorporationInventors: Wei Dai, Alyssa Ellis, Majid Salesi

Patent number: 12732613Abstract: Systems and methods for intelligent quantization for video compression are provided. In some embodiments, the methods and systems estimate a rate-distortion function is for video coding. An offset to a reconstruction process is applied, where the offset is determined based upon a frequency dependent variable and a quantization step size. The offset is then derived by transmitting the frequency dependent variable to a decoder. Additionally, a transform coefficient may be estimated as either a Laplacian or Cauchy distributions with a mean of zero and ? as a frequency dependent parameter. The offset at an encoder may be modified based on the frequency dependent variable. Modifying the offset minimizes overall distortion by moving the quantization step size closer to a centroid of the Laplacian or Cauchy distribution. Additionally, a quantization bin size may be altered to optimize distortion, and the system may determine which frequency coefficients to utilize.Type: GrantFiled: December 10, 2024Date of Patent: September 8, 2026Assignee: Agora Lab, Inc.Inventor: Wei Dai

Publication number: 20260162274Abstract: Systems and methods for the directional interpolation filter for video compression is provided. In some embodiments, the methods and systems for directional interpolation initially determine an angle of directional interpolation for a given pixel in a region of interest. The angle may be determined by performing edge detection for a textural edge in the region of interest and aligning the angle with an angle for the detected edge. Alternatively, the angle may be determined by applying a predictive method. The tap length for the pixel interpolation may also be determined. Determining tap length is an optimization between tap size and desired precision. Once tap length is determined, the systems and methods may interpolate the pixel along the angle by the determined tap length. This interpolation may include interpolation along the angle of integer pixels, or alternatively may include deriving intermediate pixels from integer pixels, and interpolation along the intermediate pixels.Type: ApplicationFiled: December 10, 2024Publication date: June 11, 2026Inventor: Wei Dai
