  • Patent number: 11380040
    Abstract: Some embodiments of the invention provide a method for concurrently presenting two synchronized animations based on an input value that is received through an input interface of a device. The method defines, based on the received input, a first animation that presents a first animated object, and then uses a set of attributes of the first animation to define a second animation that presents a second animated object. The method then displays at least portions of the first and second animations concurrently. In some embodiments, the method displays the first and second animations on a display screen of the device, or on a display screen connected to the device.

  • Patent number: 11369408
    Abstract: A catheter used for percutaneous endovascular procedures is described. The catheter is configured to be used for engagement and treatment of obstructive lesions in a patient's vasculature. The catheter includes a tube having a leading edge that is configured to score or cut a lesion in a vasculature. The tube may be an expandable outer tube, and placed around an inflatable inner tube, such that inflation of the inner tube expands the outer tube. Expansion of the inner tube may connect or laterally lock the inner tube to the outer tube, allowing both tubes to move in unison through the vasculature. The leading edge can score or cut lesions as it moves in the vasculature.

  • Patent number: 11361405
    Abstract: Dynamic spread anti-aliasing is described. In some embodiments, a filled object is segmented into control tiles. Along the object border, multiple exterior control tiles respectively correspond to multiple curves forming the border. For each curve, one side is filled and the other is anti-aliased to smooth the appearance of the filled object. Each exterior control tile is expanded to create an expanded control tile having a spread zone that includes additional pixels. For example, a control triangle is transformed into a control rectangle, and the control rectangle is enlarged to create an expanded control rectangle by extending an edge outward and away from the curve on the side to be anti-aliased. The additional pixels of the spread zone are subjected to anti-aliasing, such as by applying alpha modulation to the pixels based on respective distances between the pixels and the curve. For subpixel zoom levels, pixel color can be adjusted.
