  • Patent number: 8576034
    Abstract: A plug or connector including a coded magnet and an electrical contact. As the plug approaches a corresponding port, the coded magnet interacts with a magnet within the port. The interaction between the plug coded magnet and the port coded magnet provides a force to connect and/or align the plug with the port. Once the plug is received within the port, if a process is completed, the coded magnets polarities are altered to eject the plug from the port.

  • Publication number: 20120032765
    Abstract: The various embodiment provide fastening devices, systems and methods that utilize two or more maxels in respective correlated magnetic structures provided in a first structure and at least one second structure to fasten or repulse the first structure to or from, as the case may be, the at least one second structure. In at least one embodiment, each maxel is programmable and may vary either or both the polarity and magnetic strength of the given maxel. The variance of the polarity and/or magnetic strength of the given maxel may be programmable and may be varied to attract or repulse a second magnetic structure which desirably also contains one or maxels forming a correlated magnetic structure.

  • Publication number: 20050136290
    Abstract: Generally, methods and apparatus are disclosed for fabrication of angle-of-incidence layers on a substrate. In one embodiment, the angle-of-incidence layers may have either radial or circumferential tilt symmetry, using, for example, sputtering or evaporation techniques. In one example, an apparatus for sputtering material comprises a substrate support member, a cathode positioned in substantially facing relationship with respect to the substrate support member and a shutter plate. The shutter plate is disposed between the substrate support member and the cathode and defining an aperture for selective transmission of sputtered articles from the cathode on the basis of a non-perpendicular trajectory angle relative to a plane of the substrate support member.
