    Abstract: A method of encoding time-discrete audio signals comprises the steps of weighting the time-discrete audio signal by means of window functions overlapping each other so as to form blocks, the window functions producing blocks of a first length for signals varying weakly with time and blocks of a second length for signals varying strongly with time. A start window sequence is selected for the transition from windowing with blocks of the first length to windowing with blocks of the second length, whereas a stop window sequence is selected for the opposite transition. The start window sequence is selected from at least two different start window sequences having different lengths, whereas the stop window sequence is selected from at least two different stop window sequences having different lengths. A method of decoding blocks of encoded audio signals selects a suitable inverse transformation as well as a suitable synthesis window as a reaction to side information associated with each block.

    Abstract: A computer-implemented retirement planning system comprises data collection logic, modeling logic, and report generation logic. The data collection logic is configured to receive data pertaining to an individual planning for retirement. The retirement modeling logic is configured to process the data to generate parameters of a retirement plan. The retirement plan comprises a retirement income arrangement in which the amount of inflation-adjusted retirement income (from sources other than long term care insurance and health insurance) is larger during early years of the retirement plan and decreases as the maximum life expectancy of the individual is reached. The report generation logic being configured to generate a retirement plan report describing the retirement income arrangement.

    Abstract: A process that allocates bits for quantizing spectral components in a perceptual coding system is performed more efficiently by obtaining an accurate estimate of the optimal value for one or more coding parameters that are used in the bit allocation process. In one implementation for a perceptual audio coding system, an accurate estimate of an offset from a calculated psychoacoustic masking curve is derived by selecting an initial value for the offset, calculating the number of bits that would be allocated if the initial offset were used for coding, and estimating the optimum value of the offset from a difference between this calculated number and the number of bits that are actually available for allocation.

    Abstract: A canting ballast twin foil (CBTF) sailing yacht constructed according to the invention includes a sailing hull, a ballast, a ballast-supporting structure, and an onboard ballast drive system. The ballast drive system moves the ballast in order to vary the counter-heeling force it produces underway. Twin foils that depend downwardly from the hull in positions fore and aft of the ballast provide leeway and steering control. An onboard main engine drive system provides power, either directly by suitable mechanical coupling or indirectly through charging of the battery/electric system, for one or more of a canting system, a leeway, and/or steering control system. The onboard main engine drive system may also power a yacht-propelling propeller.
