Abstract: Techniques for presenting a content item with a media item are described. The techniques include receiving user input indicating a placement preference for a content item to be presented with a media item. The placement preference indicates a presentation preference of the content item relative to presentation of the media item. The placement preference is used to influence selection of a media item with which the content item is to be presented.

Abstract: A filling device is provided, including a pump and a liquid transferring handle. The liquid transferring handle includes a grip portion, an inlet portion, an outlet portion which is in communication with the inlet portion, a channel which is in communication between the inlet portion and the outlet portion, and a window through which an interior of the channel is viewable. The inlet portion is detachably connected and in communication with the pump.

Abstract: Traces on a PCB can be spaced closer together than in conventional layouts, which previously required the pair-to-pair spacing for the high-speed differential stripline signals to be at least 5H if the signals are originating from the same source and 7H when the signals on two pairs of transmission lines in the traces originate from different sources. Traces may be spaced closer together when, for example, a ratio of the core height to the prepreg height of the printed circuit board is approximately equal to one. Traces may be spaced closer together when, for example, a ratio of the trace spacing distance to the core height distance is less than approximately one.

Abstract: A circuit board pad resonance control system includes a board. A signal transmission line is included on the board. A plurality of connector pads are positioned on the board. A first connector pad receives the signal transmission line adjacent a first end of that connector pad. The first connector pad includes a mounting surface that mounts directly to a coupling element that is configured to couple a subsystem to the board, and reduces a resonance that is produced by an open portion of a signal transmission path that is created when the coupling element is directly mounted to the mounting surface of the first connector pad in a first orientation. In a specific example, the mounting surface may include a plurality of protrusions, a plated surface, and/or a mask that reduces the conductivity of the connector pad which reduces signal integrity issues due to resonance.
