  • Publication number: 20200219636
    Abstract: A shielded electrical ribbon cable includes adjacent first and second longitudinal conductor sets where each conductor set includes two or more insulated conductors. The first conductor set also includes a ground conductor that generally lies in the plane of the insulated conductors of the first conductor set. At least 90% of the periphery of each conductor set is encompassed by a shielding film. First and second non-conductive polymeric films are disposed on opposite sides of the cable and form cover portions substantially surrounding each conductor set, and pinched portions on each side of each conductor set. When the cable is laid flat, the distance between the center of the ground conductor of the first conductor set and the center of the nearest insulated conductor of the second conductor set is ?1, the center-to-center spacing of the insulated conductors of the second conductor set is ?2, and ?1/?2 is greater than 0.7.

Each insulative layer may be adhered to the conductors and may include alternating substantially parallel thicker and thinner portions extending along the length of the cable. The thicker portions of the first and second insulative layers are substantially aligned in one to one correspondence. Each corresponding thicker portion of the first and second insulative layers have at least one conductor in the plurality of conductors disposed therebetween. The thicker portions may have an effective dielectric constant less than 2.

  • Publication number: 20200161023
    Abstract: A shielded electrical cable includes conductor sets extending along a length of the cable and spaced apart from each other along a width of the cable. First and second shielding films are disposed on opposite sides of the cable and include cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the films in combination substantially surround each conductor set. An adhesive layer bonds the shielding films together in the pinched portions of the cable. A transverse bending of the cable at a cable location of no more than 180 degrees over an inner radius of at most 2 mm causes a cable impedance of the selected insulated conductor proximate the cable location to vary by no more than 2 percent from an initial cable impedance measured at the cable location in an unbent configuration.

  • Publication number: 20190349727
    Abstract: A wireless sensor communication system for an enclosure includes a communication gateway and communication nodes within the enclosure. Each communication node includes a processor, a sensor, and a communication module. Each of the communication nodes is configured to wirelessly transmit information within the enclosure to another one of the communication nodes, and at least one of the communication nodes has an obstruction with the communication gateway impeding direct wireless communication with it. The communication nodes are configured to aggregate information received from obstructed communication nodes and wirelessly transmit the aggregated information. The aggregation of information for transmission provides for hopping communication to send sensor data or other information from the obstructed communication nodes to the communication gateway via other communication nodes.

Each of the plurality of resonators has a diameter selected based at least in part on a wavelength of the electromagnetic wave and is formed of a dielectric material having a resonance frequency selected based at least in part on a frequency of the electromagnetic wave. Each of the plurality of resonators also has a relative permittivity that is greater than a relative permittivity of the substrate. At least two of the plurality of resonators are spaced within the substrate according to a lattice constant that defines a distance between a center of a first one of the resonators and a center of a neighboring second one of the resonators.
