Abstract: A device that includes a first board, a second board, and coaxial cable coupled to the first board and the second board. The coaxial cable includes a multi-line coaxial cable configured to provide at least two electrical paths for electrical currents between the first board and the second board. A first plug is coupled to the first board. A second plug is coupled to the second board. The coaxial cable includes a first receptacle and a second receptacle. The first receptacle is configured to couple to the first plug. The second receptacle is configured to couple to the second plug. The coaxial cable is configured to provide (i) a first electrical path for a first electrical current between the first board and the second board, and (ii) a second electrical path for a second electrical current between the first board and the second board.

Abstract: Apparatus, methods, and computer-readable media for implementing a display-side antenna are disclosed herein. An example apparatus for wireless communication includes a housing and a display device supported by the housing. The example display device includes at least a glass cover and a panel positioned between the glass cover and an internal surface of the housing. The panel may be configured to output graphical content for presentment on the glass cover via pixels arranged within a visible area of the panel. The example apparatus also includes an antenna array. The antenna array may be configured to facilitate wireless communication at the apparatus. The antenna array may be positioned to overlap a portion of the visible area of the panel and configured to allow graphical content output by the panel to display on the glass cover at the overlapped portion of the visible area.

Abstract: This disclosure provides systems, methods and apparatus for increasing the uniformity of illumination provided by frontlight systems using multiple discrete light sources. In one aspect, a phosphor material can be disposed between the discrete light sources and a light-turning waveguide, so that at least some of the light emitted by the discrete light sources is absorbed and re-emitted by the phosphor material. The light re-emitted by the phosphor material can have a more diffuse directional profile than the light emitted by the discrete light sources, and injecting this more diffuse light into the waveguide can reduce optical effects which provide non-uniform illumination across the waveguide.
