  • Patent number: 9830409
    Abstract: A method for making an electromagnetic band gap structure includes performing a single full wave simulation for the structure using a computer to perform the simulation, extracting a multiple port scattering matrix based on the single full wave simulation using a computer, and measuring or estimating a transmission of waves across the body between a first port and a second port of the body. The body has multiple ports between the first port and the second port that are defined by scattering elements using the computer. The matrix may be reduced to a two by two matrix recursively one dimension at a time using the computer.

  • Patent number: 9804411
    Abstract: A skin contact pad for eyeglass frames that helps increase the friction between the skin and the eyeglasses. The skin contact pad has a body with a face surface that touches the skin of a person wearing the eyeglasses. Concavities are formed on the skin contact pad. Each of the concavities has a concave surface defined within an encompassing base. The encompassing base of each concavity is independent and complete. As the concavities move across skin, the skin bulges slightly into the concavities. As the skin moves under the concavities, the bulges move and a slight suction is created within the concavities that bias the skin contact pad toward the skin. The bias that is created helps hold the eyeglasses in place on the head of a user.

  • Patent number: 9742522
    Abstract: A system for interference suppression onboard a satellite includes a beamforming module that processes radio-frequency (RF) signals originated from a plurality of antenna elements of an array antenna to generate multiple analog signals. At least one of the analog signals is an anti-interference signal. Analog-to-digital converters convert the analog signals to a number of digital signals. A processing module processes the digital signals to generate a phase and amplitude control signal. A summation module generates one or more composite signals with reduced interference.

  • Patent number: 9300054
    Abstract: A new class of feed horns is provided based on the use of metamaterial printed circuit board (PCB) liners on the walls of the feed horns. These feed horns may be implemented to achieve low cost operation. PCBs making up the metamaterial liner may be assembled together in such a manner as to form a feed horn with a square or rectangular aperture shape, although other suitable shapes are possible. These PCBs may be fabricated from standard low cost, off-the-shelf dielectric material. A conductor artwork pattern on the PCB surface forming the interior surface of the feed horn can be designed such that the PCB feed horn yields radio frequency (RF) properties similar to that of a corrugated feed horn. A simple flat plate ground plane bonded to the back side of the PCB can serve as the feed horn structure.

  • Patent number: 9128303
    Abstract: An eyeglass assembly that enables eyeglasses to be worn more comfortably when lifted above the eyes and onto the head. The eyeglasses have a frame with a bridge. Two pad arms may extend from the frame under the bridge. Two nose pads are provided at attach to the frames either directly or with the pad arms. Each of the nose pads contains a nose contact surface. Two complex pad structures are provided that either replace or attach to the nose pads. Each of the complex pad structures has a first contact surface and a second contact surface. The first contact surface lays parallel over the nose contact surface of the nose pad. The second contact surface is oriented to be generally perpendicular to the first contact surface. When the set of eyeglasses are lifted above the eyes, the second contact surface can directly rest against the wearer's head without causing discomfort.

  • Publication number: 20150123843
    Abstract: A system for interference suppression onboard a satellite may include an antenna that is configured to receive uplink signals from a ground-coverage area and to generate a first signal. A spot-beam antenna may be configured to receive interference signals and to generate a second signal. A processor may be configured to receive the first signal from the antenna and the second signal from the spot-beam antenna and to perform a cross-correlation to generate a composite signal that includes a null at an interference frequency. The antenna may be a shaped reflector antenna and the spot-beam antenna may be a parabolic reflector antenna.

  • Patent number: 8912973
    Abstract: Examples of the present invention include metamaterials, including metamaterial lenses, having material properties that approximate the behavior of a material with low (0<n<1) effective index of refraction. Metamaterials may be designed and tuned using dispersion engineering to create a relatively wide-band low-index region. A low-index metamaterial lens created highly collimated beams in the far-field from a low-directivity antenna feed.

  • Patent number: 8820921
    Abstract: A system and method for connecting eyeglasses or a similar device to the ear of a person, while enabling the device to be selectively raised and lowered as needed. A set of ear anchors attach to a wearer's head. Each of the ear anchors has a pinna loop that is sized to encircle the pinna of the ear. An arm is supported by each of the ear anchors. Each arm extends forward of the ear anchors toward the eyes of the wearer. The temple elements of the eyeglasses interconnect with the arms using connectors. The connectors can be formed into the structure of the arms or can be separate elements that mechanically attach to the arms. The connectors engage the temple elements yet enable the temple elements to be selectively manipulated between a functional position and a raised position.

  • Patent number: 8466370
    Abstract: Various aspects of the disclosure provide low index metamaterials. The low index metamaterials may be used to form soft and/or hard electromagnetic (EM) boundaries to facilitate desired EM performance or propagation in applications including feed horns, spatial feed/combiners, isolation barriers between antennas or RF modules, and reduced radar cross-section applications. In one aspect, a low index metamaterial comprises a dielectric layer and a plurality of conductors on a surface of the dielectric layer, embedded in the dielectric layer or both, wherein the low index metamaterial appears as a medium having a dielectric constant less than one with respect to electromagnetic waves at predetermined frequencies and propagating at grazing angles with respect to a surface of the low index metamaterial.
