  • Patent number: 7795563
    Abstract: A technique for the design of 3-D RF welding electrodes by first modeling the surface of the welded part perimeter as a spline in a 3-D CAD program, and then dividing the spline up into multiple, small straight segments. The straight segments are offset simultaneously in opposite directions from the spline, to form two sets of straight segments, each set being equidistant from the spline, with the gap between the two sets equal to the target thickness of the welded package. New die faces are constructed from each of the sets using smoothing techniques, and 3-D models of the die faces are manufactured to check accuracy of the design, making sure that all the corresponding points of the pair of electrodes are equidistant, thereby creating a strong weld with good cosmetic results all along the parts being joined.

  • Publication number: 20090133802
    Abstract: A method of welding materials includes obtaining a first material having a first thermoplastic layer formed thereon; obtaining a second thermoplastic layer; positioning the first material and the second thermoplastic layer such that the first thermoplastic layer faces the second thermoplastic layer; applying energy to the first thermoplastic layer and the second thermoplastic layer at a first location to establish a first weld; applying energy to the first thermoplastic layer and the second thermoplastic layer at a second location, the second location being offset from the first location, a portion of the second location overlapping a portion of the first location.

  • Patent number: 7281430
    Abstract: An inflatable air cell pressure transducer. The air cell has a concavity formed therein. The concavity has two edges, wherein increased pressure within the air cell causes contraction of the concavity moving the two edges closer.
