Abstract: Example channel circuits, data storage devices, and methods for asynchronous sampling from an oversampled analog-to-digital converter are described. The channel circuit may include an analog-to-digital converter configured to generate an oversampled digital signal from an analog data signal using a sample rate that is an integer multiple of the baud rate of the channel circuit. A digital sample interpolator may then interpolate interpolated digital signal values from multiple signal values of the oversampled digital signal and select values at baud rate to generate a baud rate digital signal. The baud rate digital signal may be used by an iterative detector in a timing loop and, once a target timing is achieved, for the iterative detector to detect data bits from the interpolated digital signal.

Abstract: According to various aspects, exemplary embodiments are provided of antenna assemblies. In an exemplary embodiment, an antenna assembly generally includes at least one antenna element configured to be operable for receiving high definition television signals.

Abstract: Various examples are provided for site specification for directional guided surface wave transmission in a lossy media. In one example, a probe site includes a propagation interface including first and second regions comprising different lossy conducting mediums. A guided surface waveguide probe positioned adjacent to the first and second regions can generate at least one electric field to launch a guided surface wave along the propagation interface in a radial direction defined by the first region and restricted by the second region. The propagation interface can also include additional regions comprising the same or different lossy conducting mediums. One or more of the regions can be prepared regions. In some cases, the regions can correspond to a terrestrial medium (e.g., a shoreline) and water (e.g., seawater along the shoreline).

Abstract: A system for aligning a leading vehicle with the vehicle to be trailed, the leading vehicle being of the type having a rearward window facing the trailing vehicle and a rear hitch for attaching a tongue of the trailing vehicle thereto. The system includes an indicating mark on the rearward window, and a rod mounted on the tongue of the trailing vehicle, the rod telescoping in both the vertical and horizontal directions such that the dimension of the rod may be adjusted so that the extremity of the rod comes into contact with the rearward window immediately adjacent the indicating means when the hitch of the leading vehicle is in alignment with the tongue of the trailing vehicle.
