Abstract: An apparatus comprises a plurality of power sources, one or more processors embedded with the plurality of power sources, and memory storing processor executable instructions that, when executed by the one or more processors, cause the apparatus to modify duty cycles of the power sources, and to modify timing for each phase of a multiphase cycle. In some cases, the apparatus: transfers, for each phase of the multiphase cycle, power from a different power source of a plurality of power sources to a load; determines, for each phase of the multiphase cycle, an input voltage associated with the transferred power, an output voltage associated with the transferred power, and current from the power source associated with the transferred power; determines a duty cycle associated with the power source; modifies duty cycles of the power sources; and modifies timing for each phase of the multiphase cycle.

Abstract: The present invention discloses a method for determining an optimal piano hammer felt voicing technique for voicing an unvoiced tone in a piano so as to achieve a predetermined standard of tonal quality associated with a given voiced tone using a computer program. The method comprises a) creating a library comprising at least two records wherein each record comprises a transfer function and a voicing technique wherein said transfer function mathematically expresses the effect upon tonal quality of said voicing technique; b) determining the harmonic profile for each of said unvoiced and voiced tones; c) identifying the record in said library that contains the transfer function that is most similar to the voiced transfer function that would be calculated from the harmonic profiles of said unvoiced and voiced tones; and d) disclosing the voicing technique that is contained in said identified record.
