  • Multiple array antenna system
    Patent number: 6483472
    Abstract: An antenna system suitable for use in communicating with satellites has multiple antenna units adjacent to each other and oriented in the same direction. These antenna units are driven together in tandem in altitude and azimuth by a common drive unit. The signals received by the antenna are combined together in an in phase relationship in a combiner unit to provide received signals which reinforce each other.
    Type: Grant
    Filed: January 11, 2001
    Date of Patent: November 19, 2002
    Assignee: Datron/Transo, Inc.
    Inventors: Frank W. Cipolla, John Sclimenti, John DiGioia

  • Circular warp-knit electromagnetic emission-shielding gasket
    Patent number: 5603514
    Abstract: A gasket is disclosed for shielding from electromagnetic emissions and interference (EMI) that exhibits excellent characteristics of recovery, bending, and tangential compression over a wide range of frequencies. The gasket comprises a knitted core of monofilament synthetic polymer yarns, and a circular warp knitted sheath over the monofilament knitted core, with the sheath being sufficiently conductive to provide shielding from electromagnetic interference over a wide range of frequencies.
