  • Patent number: 12106531
    Abstract: To improve the accuracy and efficiency of object detection through computer digital image analysis, the detection of some objects can inform the sub-portion of the digital image to which subsequent computer digital image analysis is directed to detect other objects. In such a manner object detection can be made more efficient by limiting the image area of a digital image that is analyzed. Such efficiencies can represent both computational efficiencies and communicational efficiencies arising due to the smaller quantity of digital image data that is analyzed. Additionally, the detection of some objects can render the detection of other objects more accurate by adjusting confidence thresholds based on the detection of those related objects. Relationships between objects can be utilized to inform both the image area on which subsequent object detection is performed and the confidence level of such subsequent object detection.

  • Patent number: 12094973
    Abstract: Embodiments of the present disclosure provide a method for forming backside metal contacts with reduced Cgd and increased speed. Particularly, source/drain features on the drain side, or source/drain features without backside metal contact, are recessed from the backside to the level of the inner spacer to reduce Cgd. Some embodiments of the present disclosure use a sacrificial liner to protect backside alignment feature during backside processing, thus, preventing shape erosion of metal conducts and improving device performance.

  • Patent number: 12093202
    Abstract: The disclosure provides a data bus inversion (DBI) encoding device and a DBI encoding method. The DBI encoding device includes a comparator circuit, a first controllable inverting circuit and a second controllable inverting circuit. The comparator circuit checks the number of the different bits between a first raw data and a second raw data. Based on the number of the different bits, the first controllable inversion circuit determines whether to invert a first DBI bit corresponding to the first raw data as a second DBI bit corresponding to the second raw data. The second controllable inversion circuit determines, based on the second DBI bit, whether to adopt the second raw data as a second encoded data corresponding to the second raw data, or invert the second raw data to generate the second encoded data.

  • Publication number: 20240299663
    Abstract: The application describes syringe carriers for medicament delivery devices such as autoinjectors. Methods of assembly are described, including a method of assembling a sub-assembly of a medicament delivery device. The method includes the steps of providing a housing, a syringe carrier and a syringe, wherein the housing extends along a longitudinal axis from a proximal end to a distal end; inserting the syringe carrier into the housing so that the syringe carrier is aligned with the housing along the longitudinal axis and inserting the syringe into the syringe carrier in the longitudinal direction. The syringe carrier remains aligned with the longitudinal axis during insertion of the syringe into the syringe carrier. As the syringe is inserted into the syringe carrier, the syringe rotates from a first position parallel to the longitudinal axis to a second position that is not parallel to the longitudinal axis and then to a third position parallel to the longitudinal axis.
