Systems, methods, and products for language learning that may extract text from various resources having text, using various natural-language processing features, which can be combined with custom-designed learning activities to offer a needs-based, adaptive learning methodology. One embodiment provides a method for transferring data in an integrated circuit. An imaging pixel includes a photodiode region formed within the semiconductor layer. The dynamic service interface implementation is executed to allow access to the client component to a service provided by the target component. The connection wiring pattern 27 is connected to the through wiring pattern 28 on the other LED board 18. In one illustrative embodiment, a valve body receives the waterway, and at least one retainer restrains movement of the waterway.
