Abstract: In inductive devices and transformers, a periodic transformation system reduces or prevents heat or distortion, reduces resistance or impedance and improves output energy. In one embodiment, the Tru-Scale Reactance Transformation System provides an harmonic relationship among the core, winding, magnetic flux, and the current in order to maximize energy output of inductive devices, such as a transformer, by reducing EMF collisions in any type of power systems.

Abstract: In an AC or DC motor operation and power generation system, a periodic transformation system reduces or prevents harmonic distortion, reduces resistance or impedance, and improves energy efficiency in a signal either consumed, such as in a motor, or produced, such as in a generator. In one embodiment, the TruScale Reactance Transformation System or the Eastern Modified TruScale Octave Transformation System are the periodic transform systems provided to prevent overtone collisions in current and voltage signals, in order to maximize energy spectral density, and to precondition either DC or AC signals.

Abstract: A noise suppression device receives data representative of a noise-corrupted signal which contains a speech signal and a noise signal, divides the received data into data frames, and then passes the data frames through a pre-filter to remove a dc-component and the minimum phase aspect of the noise-corrupted signal. The noise suppression device appends adjacent data frames to eliminate boundary discontinuities, and applies fast Fourier transform to the appended data frames. A voice activity detector of the noise suppression device determines if the noise-corrupted signal contains the speech signal based on components in the time domain and the frequency domain. A smoothed Wiener filter of the noise suppression device filters the data frames in the frequency domain using different sizes of a window based on the existence of the speech signal. Filter coefficients used for Wiener filter are smoothed before filtering.

Abstract: An electronic device for improving the average deviation of a modulated signal, particularly a radio frequency (RF) modulated signal. A fixed interval scale system known as Tru-Scale, or other periodic frequency matrix data, is applied to the audio frequency component or baseband signal and increases the strength of the signal. This increase in turn produces an improved modulation model for transmission. In addition, impedance in the baseband signal is reduced, requiring less power to modulate the carrier signal. The process increases periodicity within the baseband signal, improving the Signal to Noise ratio and other measurable performance characteristics. By utilizing signal energy more effectively, more powerful propagational efficiencies result.

Abstract: A method and system for representing speech with greatly reduced harmonic and intermodulation distortion using a fixed interval scale, known as Tru-Scale. Speech is reproduced in accordance with a frequency matrix which reduces intermodulation interference and harmonic distortion (overtone collision). Enhanced speech quality and reduced noise results from increasing the signal-to-noise ratio in the processed speech signal. The method and system use an Auto-Regressive (AR) modeling technique, using, among other approaches, Linear Predictive Coding (LPC) analysis. In accordance with another aspect of the invention, a Fourier transform-based modeling technique also is used. The application of the system to speech coders also is contemplated.

Abstract: An electronic musical instrument for reproducing chords in a fixed interval scale, know as Tru-Scale, without overtone collision. The instrument includes a memory for storing of frequency information corresponding to respective notes for producing tones using the Tru-Scale interval system. The inventive instrument reproduces single notes and chords in accordance with an interval system which eliminates dissonance, allows complete modulation, in all key signatures, and pure tone chords without altering the keyboard. The invention also contemplates the use of the Tru-Scale frequencies with all MIDI interface compatible instruments, in conjunction with a suitable tone generator, or through internal or external memory sources.
