    Abstract: Methods and systems for manufacturing an implantable medical device, such as a stent, from a tube with desirable mechanical properties, such as improved circumferential strength and rigidity, are described herein. Improved circumferential strength and rigidity may be obtained by inducing molecular orientation in materials for use in manufacturing an implantable medical device. Some embodiments may include inducing molecular orientation by expansion of a molten annular polymer film. Other embodiments may include inducing circumferential molecular orientation by inducing circumferential flow in a molten polymer. In certain embodiments, circumferential orientation may be induced by expansion of a polymer tube. Further embodiments may include manufacturing an implantable medical device from a biaxially oriented planar polymer film.

    Abstract: Techniques for detecting one or more touches on a touch screen are disclosed. According to one aspect of the present invention, at least three predetermined points are provided, where each of the at least three predetermined points has a wave receptor mounted thereat. When a touch to the touch screen happens, acoustic wave signals generated at the touch point are received by the wave receptors. The distances between the touch point and the three predetermined points are calculated according to the acoustic wave signals. At least three equations of circles are constructed to respectively employ the three predetermined points as their centers, the distances between the touch point and the at least three predetermined points as their radiuses. The coordinates of the touch point according to a common solution of the at least three equations are then determined. The same approach can be similarly applied to determining multiple touches on a touch screen.
