A communication signal carrier on a communication channel in a digital cable receiver can be characterized as analog without exhaustively attempting to determine a symbol rate or modulation scheme of a digital carrier. The encoding scheme allows associating a 2-D or 3-D positional localization to each of a plurality of sound sources by use of frequency independent inter-channel phase and amplitude differences. A region to be liquid-repellent is formed and further, a region to be lyophilic is formed selectively in the region to be liquid-repellent in a surface for forming a pattern, before forming a desired pattern. The template may be applied to query data for each query according to the row type to generate a sub-report. , based on an appropriate rhythm and pitch range in order to obtain natural prosody for utterances in the particular domain and with minimum coarticulation between concatenative units; a script recorder that records a speaker’s utterances of the domain strings; a recording editor that edits the recorded strings by marking the beginning and end of each word, number etc. The seal member has a number of seal ducts each aligned with one of the apertures in the connector.
