Abstract: A transformation module for transforming a first input impedance at a first transformation module terminal to a second input impedance at a second transformation module terminal for use in an RF push-pull amplifier arrangement, wherein the transformation module has a multi-ply structure. The transformation module includes a multi-ply planar substrate including a circuit board, having a first outer ply, a second outer ply and a first intermediate ply which is arranged between the first and second outer plies. The transformation module further includes an outer conductor having a first outer conductor layer and a second outer conductor layer arranged on or in the multi-ply planar substrate. The first outer conductor layer is arranged in the form of a first planar outer conductor winding having a first and second end on or in the first outer ply.

Abstract: A system for obtaining a rating stream of information concerning a media presentation is described. The client unit provides a media player. In a preferred embodiment, the client unit also provides a rating indication display. The rating can be adjusted by the user. The rating information, along with time stamp information recorded when the rating changes, is provided from the client unit to a data collection unit. The analysis unit requests data from the data collection unit, and combines the ratings information from multiple users. In a preferred embodiment, the analysis unit combines the rating information according to demographic groups based on the demographic profiles of the users.
