Patents by Inventor Andrew John Wehrli

Andrew John Wehrli has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • High performance data communications cable
    Patent number: 10832833
    Abstract: Two electromagnetic interference (EMI) controlling tape application methodologies for unshielded twisted pair (UTP) cable include Fixed Tape Control (FTC) and Oscillating Tape Control (OTC). In FTC, tape application angle and edge placement are controlled to maintain position of the tape edges over a base of nonconductive filler in the cable. In OTC, the tape application angle is continuously varied, resulting in crossing of the tape edges over all of the pairs of conductors with varying periodicity. In both implementations, the filler allows a cylindrical shape.
    Type: Grant
    Filed: March 18, 2019
    Date of Patent: November 10, 2020
    Assignee: BELDEN INC

  • HIGH PERFORMANCE DATA COMMUNICATIONS CABLE
    Publication number: 20150107872
    Abstract: The present disclosure describes two electromagnetic interference (EMI) controlling tape application methodologies for unshielded twisted pair (UTP) cable, Fixed Tape Control (FTC) and Oscillating Tape Control (OTC). In FTC, tape application angle and edge placement are controlled to maintain position of the tape edges over a base of nonconductive filler in the cable. In OTC, the tape application angle is continuously varied, resulting in crossing of the tape edges over all of the pairs of conductors with varying periodicity. In both implementations, alien crosstalk and return losses are improved, while the filler allows a cylindrical shape for optimized ground plane uniformity and stability for improved impedance and return loss performance.
