    • A magnetic rotational position sensor assembly for measurement of a rotational angular position of a rotating structure. The sensor assembly includes a shaft member extending along a primary rotational axis for primary rotational movement in response to rotation of the rotating structure, a motion conversion member structured and configured to transform the primary rotational movement of the shaft member into secondary movement, a magnet member secured to the motion conversion member for displacement along a travel path in response to the converted secondary movement of the motion conversion member, and a non-contact magnetic sensor that senses a change in position of the magnet member by sensing a corresponding variation in the magnetic field during displacement of the magnet member along the travel path in response to rotation of the rotating structure, wherein the magnetic sensor generates an output signal representative of a relative rotational angular position of the rotating structure.

    • Some embodiments provide a method of specifying speed effects for playing a video clip. The method defines a set of speed effects for the video clip. It then displays in real-time a presentation of the video clip that accounts for the set of speed effects defined for the video clip. In some embodiments, this method represents the playback speed of a video clip in terms of a graph that is part of a graphical user interface (“GUI”). This graph is defined along two axes, with one axis representing the playback time, and the other axis representing the content-time (i.e., the time within the video clip). In these embodiments, a user can change the playback speed of the video clip by using a set of GUI operations to select and modify the graph. For instance, a user can select and adjust the graph at different instances in time in order to change the playback speed of the video clip at these instances. Different embodiments use different types of graphs to represent playback speed. For instance, some embodiments use a deformable line bar that is superimposed on a rectangle that represents the video clip.
    • 一些实施例提供了一种指定用于播放视频剪辑的速度效果的方法。 该方法定义了视频剪辑的一组速度效果。 然后,它实时显示视频剪辑的呈现,该视频剪辑占用为视频剪辑定义的速度效果集。 在一些实施例中,该方法表示作为图形用户界面(“GUI”)的一部分的图形的视频剪辑的回放速度。 该图形沿两个轴定义,一个轴表示播放时间,另一个轴表示内容时间(即,视频剪辑内的时间)。 在这些实施例中,用户可以通过使用一组GUI操作来改变视频剪辑的播放速度来选择和修改图形。 例如,用户可以在不同的时间点选择和调整图形,以便在这些情况下改变视频剪辑的播放速度。 不同的实施例使用不同类型的图表来表示播放速度。 例如,一些实施例使用叠加在表示视频剪辑的矩形上的可变形线条。

    • Clock synchronization and skew adjustment circuits are described that utilize varying unit delay elements in their delay lines in either a graduated or a stepped unit time delay arrangement, allowing a reduced circuit implementation and improved lock characteristics. These graduated or a stepped unit time delays allow reduction in the number of the fine unit delay elements of the delay lines by placing a fine delay element granularity at the most critical timings to sense and adjust for the portion of the clock signal time period that are high speed or critical. This allows clock synchronization and skew adjustment circuits to be implemented in an optimized manner that exhibits a reduced overall circuit size and power consumption, while having improved lock characteristics over a wide range of frequencies.
