A brand new audio signal processing technology namely "High Audio Scene (HAS)" has been developed to compensate the inadequacies of Dolby Digital formats that widely used in daily life audio processing systems. The challenging of using Dolby systems is the expected acoustic conditions including building environment and audio configuration facilities should be satisfied. The coded multiple channels signal from HAS encoders are from ordinary stereo sources without the expensive set up in source recording. The quality of the regenerated sound is compatible to Dolby Surround EX and less acoustically controlled environment is needed. The audio systems configured either in 2.1-, 3.2- or 5.2-channel HAS format can generate a VAST and STRONG VOCAL audio effect similar to the hearing in a natural environment. However, less preserved power is need because of using interference characteristics can intensify the sound sources to many times. The technology is expected to be widely applied for different environment including classrooms, dwells, corridors, auditoriums, cinemas, and concert halls without much building re-revolution work. © 2012 IEEE.

Electrical stimulation to cardiac tissue stabilizes atrial and ventricular arrhythmia when timed to stabilize a limit cycle structure in a Poincare map. Disclosed are methods and apparatus, operational internally or externally, for removing the reentrant effects of heterogeneity present in a diseased heart and returning the heart to an improved metabolic status allowing removal of support. The methods and apparatus disclosed are also useful in the chronic surveillance and maintenance of regularized contractility in an aged or diseased heart.
