  • Patent number: 6737574
    Abstract: A detectable woven tape having multiple metallic conductors for use in detection of underground dielectric communications cable is provided. The tape provides low electrical resistance at a range of frequencies to help to permit detection of buried cable in different field conditions using commercially available detection equipment. In particular, the tape helps to provide detection of buried cable over a long distance or over a long span of conduit. The tape is lightweight and flexible and suited for use in detecting and installing fiber optic communications cable.

  • Patent number: 6734362
    Abstract: A cable assembly has a number of wires each having a central conductor and a surrounding insulating layer. Each wire is unshielded from the other wires, so that the conductor is the only conductive portion of the wire. Each wire has a first end and an opposed second end. The first ends of the wires are secured to each other in a flat ribbon portion in a first sequential arrangement, and the second ends of the wires are secured to each other in the same sequence as the first arrangement, with indicia identifying a selected wire in the sequence. The intermediate portions of the wires are detached from each other, and a sheath having a braided conductive shield may loosely encompass the wires, permitting significant flexibility of the cable.

  • Publication number: 20040079542
    Abstract: To disclose a biomedical signal cable ideally applicable to also serving as an antenna for radio transmissions. The biomedical signal cable according to the present invention is a biomedical signal cable that connects a medical telemetery having a radio transmission function and a biomedical electrode and places a selective high-resistance body with respect to a radio signal, for example, a ferrite core 120 at a position away from a base 110 of a signal cable 100 by approximately a ¼ wavelength of the transmission frequency of the medical telemetery. In this way, the present invention makes a high frequency signal produce resonance, thereby improving an antenna efficiency of the biomedical signal cable.

  • Publication number: 20040065457
    Abstract: A low cost, high performance, water-swellable, flexible reinforcement member that can be used for both optical and copper communications cable. The water-swellable reinforcement members made according to the preferred process are more rigid than known reinforcement members, but are less rigid than glass pultruded rods. Communications cables utilizing these members are lightweight, water-swellable and exhibit an improved combination of strength and flexibility compared to traditional communications cables. Further, these communication cables may then be installed into underground ducts using more economical and faster installation techniques.

  • Patent number: 6713673
    Abstract: A structure of a speaker signal line having a middle filler layer, a plurality of transmission conductors and an outer coating portion, wherein, the middle filler layer is comprised of many hollow tubes. The transmission conductors are equidistantly spaced and wrapped over the middle filler layer. The coating portion is made of polyvinyl chloride composition. The middle filler lay is formed in the way of entangling to increase its strength and flexibility. The transmission conductors are spaced mutually in different layers and wrapped over the middle filler layer in mutual contrary directions. All the elements above are combined together by adding the outer coating portion, thereby, the inductive resistance induced by the transmission conductors equidistantly spaced in different layers and wrapped in mutual contrary directions can be mutually offset.

  • Patent number: 6710243
    Abstract: A structure of signal line comprising a core portion, a middle filler layer, an obscuring layer and a coating portion, the core portion is a transmission conductor with a rectangular cross section; the obscuring layer has at least a knitted metallic obscuring layer; the coating portion has at least a layer made of polyvinyl chloride composition; and the middle filler layer is comprised of a plurality of hollow tubes. The core portion is tangled with the middle filler layer to make the line stronger in addition to being flexible, so that the line will not have the core portion damaged when it is bent to deform, plus the obscuring function of the obscuring layer, the interference among a magnetic field, radio frequencies and static electricity can be reduced, thereby, attenuation rate of the line can be reduced, distortion of the line can be smaller, and high quality of the line can be obtained.

  • Publication number: 20040045731
    Abstract: An improved audio cable comprising at least one pair of first and second insulated conductors located on opposite sides of a shielding member that extends the entire length of the cable. The first and second conductors are located on opposite sides of the shielding member. Bores, also called lenses, are formed on the shielding member that allow exposure of the magnetic fields of the first and second conductors to reduce inductance. In the first embodiment, the shielding member is spiral with the conductors on opposite sides of the shielding member. The conductors and shielding member may be covered with an outer shielding member that only extends over the lenses or the entire length of the cable and covered by a durable, protective outer cover.
