  • Patent number: 10434667
    Abstract: A double spring folding knife includes a handle having a curvilinear groove on an interior surface, and a knife blade. The knife blade has a locking pin that extends away from a first side of the knife blade and is configured to slidingly engage the curvilinear groove. A bow spring is fixed to the handle and is orientated to interact with the locking pin in order to exert a force on the locking pin during a portion of travel along the curvilinear groove. The knife also includes a coil spring having a first end fixed to the handle and a second end fixed to a second side of the knife blade, where the coil spring is configured to exert an opening force on the knife blade after the locking pin has traveled past the bow spring along the curvilinear groove.

  • Patent number: 10322017
    Abstract: A medical implant such as a self-expanding shape memory alloy stent with a strut matrix formed by cut patterns in a wall of a tubular workpiece can be enhanced by arranging for the line of the laser beam when cutting the struts to be one that does not pass through the longitudinal rotational axis of the tubular workpiece. Such “off-axis” cutting can modify the cross-sectional shape and area of each strut, along its length. Such modulation can enhance the fatigue resistance of the stent matrix, or increase the radial force that the stent matrix is capable of exerting on bodily tissue within which it is implanted.

  • Patent number: 10293418
    Abstract: A modular circular saw includes a base, a worktable disposed on the base and a workpiece supporting unit. The workpiece supporting unit has two supporting frames respectively and correspondingly located on two lateral sides of the worktable; each workpiece supporting unit has a supporting shaft and two corresponding extending shafts. Each extending shaft has one end pivotally connected to the base, another end of the extending shaft is pivotally connected to one end of the supporting shaft, correspondingly. When the workpiece supporting unit is in an extended position for receiving a workpiece, the two supporting shafts are substantially co-planar with the worktable, such that the two supporting shafts provides extra support to a workpiece of large size. When the workpiece supporting unit is in a folded position, the two supporting shafts are located above the worktable for minimizing the size of the saw and for allowing the user to grip the saw for easy transportation.
