    摘要： Circuits, apparatus, and methods that provide a connector system that can supply both power and data to a mobile computing or other type of device using a single connection. Further examples also provide a power and data adapter that can provide power and data to a mobile computing device using a single cable. Further examples provide an easy disengagement when a cable connected to the connector is pulled. One such example provides a magnetic connector that uncouples without binding when its cord is pulled. Another example prevents power from being provided at a connector insert until the connector insert is placed in a connector receptacle.

    摘要： A laser beam shaper which provides polarized output with a high spatial quality, utilizing induced stress birefringence. The laser beam shaper in which light resonates along a resonant path defined by reflective surfaces includes a solid state medium, such as a Nd:YAG rod which exhibits thermally induced stress birefringence that is of known, azimuthally independent distribution in planes perpendicular to the resonant path. On either side of the medium, quarter-wave retardation plates are provided which create essentially circular polarization of the resonant light within the medium. Sandwiching the quarter-wave plates and the medium are the first and second polarizing elements, both of which are aligned along the same preferred plane. By inducing stress birefringence in the medium, an output beam is produced. A shape defined by the distribution of the birefringence is provided. With media such as YAG, the shape of the beam is round with high quality.
