  • Publication number: 20220161002
    Abstract: A clamping device for a shaft of a catheter can include a first member rotatably coupled to a second member. The first member can have an annular element defining a central lumen, the outer surface of the annular element having a non-circular cross-sectional profile, and the second member can define a bore into which the annular element extends, the bore having a non-circular cross-sectional profile. The device can move between a release state wherein the central lumen has a first diameter, and a clamped state wherein the central lumen has a second diameter less than the first diameter. When the clamping device is in the clamped state, the clamping device can engage an outer surface of a catheter shaft and when the clamping device is in the release state, the clamping device can be moved along a length of the catheter shaft.

  • Patent number: 11315363
    Abstract: Gait, the walking pattern of individuals, is one of the most important biometrics modalities. Most of the existing gait recognition methods take silhouettes or articulated body models as the gait features. These methods suffer from degraded recognition performance when handling confounding variables, such as clothing, carrying and view angle. To remedy this issue, a novel AutoEncoder framework is presented to explicitly disentangle pose and appearance features from RGB imagery and a long short-term memory integration of pose features over time produces the gait feature.

  • Patent number: 11055989
    Abstract: Systems and methods for performing domain adaptation include collecting a labeled source image having a view of an object. Viewpoints of the object in the source image are synthesized to generate view augmented source images. Photometrics of each of the viewpoints of the object are adjusted to generate lighting and view augmented source images. Features are extracted from each of the lighting and view augmented source images with a first feature extractor and from captured images captured by an image capture device with a second feature extractor. The extracted features are classified using domain adaptation with domain adversarial learning between extracted features of the captured images and extracted features of the lighting and view augmented source images. Labeled target images are displayed corresponding to each of the captured images including labels corresponding to classifications of the extracted features of the captured images.

  • Patent number: 8216949
    Abstract: A method lor integrated circuit fabrication is disclosed. A spacer pattern is provided including a plurality ot spacers in an array region of a partially-fabricated integrated circuit. Each spacer is at least partly defined by opposing open volumes extending along lengths of the spacers. A pattern is subsequently defined in a periphery region of the partially-fabricated integrated circuit. A consolidated pattern is formed by concurrently transferring the spacer pattern and the pattern in the periphery region into an underlying masking layer. The consolidated pattern is transferred to an underlying substrate.

  • Patent number: 8207576
    Abstract: Differently-sized features of an integrated circuit are formed by etching a substrate using a mask which is formed by combining two separately formed patterns. Pitch multiplication is used to form the relatively small features of the first pattern and conventional photolithography used to form the relatively large features of the second pattern. Pitch multiplication is accomplished by patterning a photoresist and then etching that pattern into an amorphous carbon layer. Sidewall spacers are then formed on the sidewalls of the amorphous carbon. The amorphous carbon is removed, leaving behind the sidewall spacers, which define the first mask pattern. A bottom anti-reflective coating (BARC) is then deposited around the spacers to form a planar surface and a photoresist layer is formed over the BARC. The photoresist is next patterned by conventional photolithography to form the second pattern, which is then is transferred to the BARC.

  • Publication number: 20120044735
    Abstract: Methods and structures are provided for increasing alignment margins when contacting pitch multiplied interconnect lines with other conductive features in memory devices. The portions of the lines at the periphery of the memory device are formed at an angle and are widened relative to the portions of the lines in the array region of the memory device. The widened lines allow for an increased margin of error when overlaying other features, such as landing pads, on the lines. The possibility of contacting and causing electrical shorts with adjacent lines is thus minimized. In addition, forming the portions of the lines in the periphery at an angle relative to the portions of the lines in the array regions allows the peripheral portions to be widened while also allowing multiple landing pads to be densely packed at the periphery.

  • Patent number: 7960797
    Abstract: A semiconductor device structure includes staggered contacts to facilitate small pitches between active-device regions and conductive lines while minimizing one or both of misalignment during fabrication of the contacts and contact resistance between sections of the contacts. The contacts of one row communicate with every other active-device region and are staggered relative to the contacts of another row, which communicate with the remaining active-device regions. Each contact may include a relatively large contact plug with a relatively large upper surface to provide a relatively large amount of tolerance as a contact hole for an upper portion of the contact that is formed. The contact holes may be formed substantially simultaneously with trenches for conductive traces, such as bit lines, in a dual damascene process. Intermediate structures are also disclosed, as are methods for designing semiconductor device structures.
