Abstract: The present invention is a language learning method and system. The present invention records a conversation by two native-speakers in a target language. The conversation is transcribed and translated. The transcribed and translated versions are both segmented into snippets that last between thirty (30) seconds and five (5) minutes. A concordance is created from the transcribed segmented conversation. A pareto distribution is created from the concordance. A set of high-frequency, non-trivial words and phrases are defined by the pareto distribution. A language learning application teaches a student the target language by presenting language learning exercises to the student which concentrate on the high-frequency, non-trivial words.

Abstract: The present invention is a descriptivist language learning method and system. The present invention records a conversation by two native-speakers in a target language. The conversation is transcribed and translated. The transcribed and translated versions are both segmented into snippets that last between thirty (30) seconds and five (5) minutes. A concordance is created from the transcribed segmented conversation. A pareto distribution is created from the concordance.

Abstract: A dual water heating system uses a pump for pumping water from a swimming pool or spa. A filter is coupled to an output of the pump for filtering the water. A water heater heats the water and returns heated water to the swimming pool or spa. A network of non-corrosive piping is disposed within the swimming pool support structure. A plurality of steam ports are coupled to exit points of the network of piping. A steam generator provides steam to the network of piping for transporting the steam to the steam ports and injecting the heated water into the swimming pool or spa. An energy source supplies energy to the steam heater. A motorized or hand-push cart is used to transport the steam heater and energy source. The steam ports are provided along sidewalls or bottom surface of the swimming pool and spa support structure. The steam ports are contained within cavities formed in the support structure.
