Abstract: A casing for housing a fiber optic transceiver for use in a fiber optic connector can include a top surface, a bottom surface and one or more lateral surfaces, wherein the top surface and at least one or more lateral surfaces are at least in parts electrically conductive, and wherein the bottom surface of the casing comprises one or more solder pads.

Abstract: A dielectric waveguide and/or a cable for transmission of millimeter-wave signals. The dielectric waveguide and/or the cable comprises an inner core having a dielectric medium adapted to transmit a millimeter-wave signal by carrying an electromagnetic field along the dielectric waveguide and/or the cable. The dielectric medium is a dielectric material having dielectric properties adapted to confine the propagating electromagnetic field to the inner core, while adding low transmission loss at signal frequencies in a millimeter-wave frequency range. The dielectric medium may be provided as a core of solid dielectric material, one or more bundles of fibers that extend along the length of the inner core, or as powder and/or granulate of dielectric material that fills the volume of the inner core. The dielectric material may be quartz or alumina.

Abstract: A dielectric waveguide for propagating electromagnetic signals comprises a cladding and an electrically conductive shield. The cladding has a body composed of a first dielectric material. The body defines a core region therethrough that is filled with a second dielectric material different than the first dielectric material. The cladding includes at least two ribs extending from an outer surface of the body to distal ends of the ribs. The electrically conductive shield engages the distal ends of the ribs and peripherally surrounds the cladding such that air gaps are defined radially between the outer surface of the body and an interior surface of the shield.

Abstract: A head-tracking system and a method for operating a head-tracking system in which a stationary reference point is detected are provided. A detector for detecting the position of a head is calibrated based on the detected stationary reference point. In one example implementation, the detection of the stationary reference point is used to determine the position of the head.
