20140193009 | METHOD AND SYSTEM FOR ENHANCING THE INTELLIGIBILITY OF SOUNDS RELATIVE TO BACKGROUND NOISE - A novel dual-microphone speech enhancement technique is proposed that utilizes the coherence function between input signals as a criterion for noise reduction. The technique is based on certain assumptions regarding the spatial properties of the target and noise signals and can be applied to arrays with closely spaced microphones, where noise captured by sensors is highly correlated (e.g., inside a mildly reverberant environment). The proposed algorithm is simple to implement and requires no estimation of noise statistics. In addition, it offers the advantage of coping with situations in which multiple interfering sources located at different azimuths might be present. | 07-10-2014 |

20090110674 | Health supplement - A health supplement consisting of numerous ingredients from several general groups including: anti-aging, anti-oxidant, vitamins, minerals, and elemental substances including metals. The supplement is specifically formulated for maximizing synergistic interaction of the ingredients while eliminating harmful interaction among the ingredients. A holistic approach to health is followed with ingredients to aid all systems of the human body. By addressing all human body systems, the supplement acts as a precursor to anti-aging and, when body systems are detoxified and oxidation is controlled, the effect of aging may be reversed. | 04-30-2009 |

20130022223 | AUTOMATED METHOD OF CLASSIFYING AND SUPPRESSING NOISE IN HEARING DEVICES - The claimed invention is directed to a real-time noise classification and tuning system for cochlear implant and other hearing device applications. The system is capable of automatically selecting the optimized parameters of a noise suppression algorithm in response to different noisy environments. The feature vector and the classifier deployed in the system to automatically identify the background noise environment are selected so that the computation burden is kept low to achieve a real-time throughput. The results reported herein indicate improvement in speech enhancement when using this intelligent real-time hearing device system. | 01-24-2013 |
