  • Patent number: 7832120
    Abstract: A moisture repellant tread is provided for a positive displacement of moisture to secure the traction in the bottom of a shoe. The tread comprises a base plate and multiple short bundles of absorbent fibers. The base plate has a top surface locally bonded to the outsole with a lateral clearance between the base plate and outsole about the bonded areas, a bottom surface for contacting a floor and multiple closely arranged recesses open to the bottom surface and communicating through smaller openings formed at the top surfaces concentrically of the recesses. The fiber bundles are partially implanted in the recesses for displacing water absorbed from the floor upon contact through the openings at the top surfaces to the lateral clearance whereby the tread secures an increased traction as a wearer steps on the tread through the shoe even on a film of moisture.

  • Patent number: 7832861
    Abstract: A method of making a reverse progressive lens has the steps of selecting a standard progressive lens having a distance zone, a transition zone and a near zone; selecting an add determination that is double or more than double in power; reversing the regular progressive lens by orienting it upside down; and cutting away the near zone so that the transition zone becomes the new near zone. To maintain convergence of the corridor channel, one by orders the OS lens with the OD power and the OD lens with the OS power. The method also includes measuring a distance PD, measuring the segment height and keeping the same cylinder axis such that rotating the lens 180° does not change the axis position. Selecting a standard progressive lens may include one with a distance zone, a corridor/transition zone and a near zone.

  • Patent number: 7814589
    Abstract: The terrace comforter is made by a shell with many tubes of the same width and length sitting side by side from one end of the shell extended to the other end. Each tube consists of several and the same number of baffled boxes separated by walls between them. There are one or two small holes on the baffled walls in each box so that the filling materials can be blown into the box with a metal tube inserted through the holes on those baffled walls into the box and stay there for a long period of time before moving into the next boxes. The height of boxes can be the same or different as long as the space in each box is large enough for the filling material to expand to its fullest volume.
