  • Publication number: 20250129709
    Abstract: A method of preventing a collision of a subject wellbore in a downhole environment includes receiving offset wellbore data corresponding with one or more offset wellbores and identifying, based on the offset wellbore data, one or more no-go zones for each of the one or more offset wellbores. The method further includes determining a plurality of safe points corresponding with a potential intersection of the subject wellbore with the one or more no-go zones and, defining an escape zone within the plurality of safe points. The method further includes determining a trajectory for the subject wellbore within the escape zone.

  • Publication number: 20250114222
    Abstract: The present invention discloses a biodegradable molybdenum-based flow diverter and a preparation method thereof, wherein the preparation method comprises the following steps: step 1. pretreatment of a molybdenum wire: cleaning and drying the molybdenum wire, and then weaving to obtain the molybdenum-based flow diverter; step 2. performing heat treatment on the molybdenum-based flow diverter in the step 1; and step 3. performing surface chemical polishing treatment on the molybdenum-based flow diverter subjected to the heat treatment in the step 2. The present invention solves the technical problem that the flow diverter in the prior art cannot be degraded in vivo and therefore easily causing various complications. It provides also improved mechanical property, MRI magnetic resonance imaging (MRI) compatibility as well as biocompatibility, and particularly has the function of promoting rapid endothelialization, compared with other degradable materials.

  • Patent number: 12242583
    Abstract: A user device, such as a smartphone or laptop, may be password (passphrase) protected. The user device may combine biometric input analysis, such as facial recognition, with viseme analysis to authenticate a user attempting to use a password (passphrase) to access the user device. Secure authentication methods and systems are described that account for variations in how, based on the user's emotion (e.g., mood, temperament, unique pronunciation, etc. . . . ), a password (passphrase) may be presented to the user device.

  • Publication number: 20240056637
    Abstract: Methods, systems, and apparatuses are described for performing trick plays of segmented video content are provided. A point at which a trick play begins may be based on a playback time associated with a video segment that includes the video frame currently displayed when a request to start the trick play is received. A point at which to resume playback of the normal rate video content may be similarly based on a trick play playback time associated with a trick play video segment that includes the trick play video frame currently outputted when a request to stop the trick play is received.
