  • Patent number: 10784583
    Abstract: Arrays of low permittivity Polymer-based Resonator Antenna elements with different configurations. Individual array elements can be fabricated with complicated geometries; these elements can be assembled into complicated patterns as a single monolithic fabricated structure using narrow wall connecting structures, which removes the requirement to position and assemble the array elements. Monolithic array structures can be assembled as sub-arrays in larger array structures. Elements, sub-arrays, and arrays can also be formed by inserting dielectric materials into cavities defining their lateral geometries, and fabricated in polymer templates. The polymer templates can be removed or retained to function as part of the antenna.

  • Publication number: 20200264084
    Abstract: Methods of detecting pipeline weakening are described herein. The methods include creating a pressure wave in a fluid flowing in a pipeline using an input transducer located at a first position along the pipeline; measuring the pressure wave using an output transducer positioned at a second position along the pipeline that is spaced from the first position, and generating an output signal based on the pressure wave; analyzing the output signal to determine a stiffness of a sidewall of the pipeline positioned between the input transducer and output transducer; and determining if the sidewall includes a defect based on the stiffness of the sidewall, including analyzing a frequency response of the output signal to detect the defect.

  • Patent number: 10340599
    Abstract: Antennas suitable for use in compact radio frequency (RF) applications and devices, and methods of fabrication thereof. Described are resonator antennas, for example dielectric resonator antennas fabricated using polymer-based materials, such as those commonly used in lithographic fabrication of integrated circuits and microsystems. Accordingly, lithographic fabrication techniques can be employed in fabrication. The antennas have metal inclusions embedded in the resonator body which can be configured to control electromagnetic field patterns, which serves to enhance the effective permittivity of the resonator body, while creating an anisotropic material with different effective permittivity and polarizations in different orientations.

  • Patent number: 10004723
    Abstract: An intravaginal device that provides biologically active circulating concentrations of an aromatase inhibitor for at least about of 4 days. Liposome-based and a wax-based formulations were used to assess letrozole diffusion through bovine vaginal mucosa in a diffusion chamber study. The wax-based vehicle was selected for further development of a letrozole intravaginal device based on its steady release rate. The addition of a letrozole-containing gel coating improved initial absorption and hastened the increase on plasma concentrations of the active ingredient, while the letrozole-containing wax-based vehicle maintained prolonged delivery from the intravaginal device.
