20110040205 | Treatment for Alleviating Tinnitus and Hyperacusis with Auditory Stimulation by Compensating for Hearing Loss and Loss of Non-Linear Compressions - An auditory stimulation treatment for alleviating tinnitus and hyperacusis by compensating for hearing loss and loss of non-linear compression. Natural auditory signals are delivered correcting for hearing loss and compressive non-linearity, both determined at separate frequency bands for the individual subject. This differs from existing treatment in that synthetic “masking” signals are not delivered, but rather the natural auditory input to the subject is modified. Consequently, the method is more akin to a conventional hearing aid. In contrast to conventional hearing aids, however, perception thresholds are specifically corrected and non-linear compression is matched to the specific hearing deficit of the user. | 02-17-2011 |
20140079251 | METHOD AND APPARATUS FOR SENSORY SUBSTITUTION - An apparatus and method for use in treating tinnitus, employs a sound processing unit, a tactile unit, and an interface therebetween. The tactile unit comprises an array of stimulators each of which can be independently actuated to apply a tactile stimulus to a subject, and an input for receiving a plurality of actuation signals from the interface and directing individual actuation signals to individual stimulators. The sound processing unit receives an audio signal at an input, analyses the signal with a digital signal processor to generate the actuation signals which are representative of the audio signal, and provides the plurality of actuation signals to the interface. In a preferred embodiment the digital signal processor divides the audio signal into a series of frames in the time domain, performs a transform on each frame to generate a set of coefficients representing said frame, and maps the set of coefficients to a set of actuation signals to be applied to the array. | 03-20-2014 |

20090077543 | AUTOMATIC DERIVATIVE METHOD FOR A COMPUTER PROGRAMMING LANGUAGE - The disclosed system provides a transformation-based implementation of forward-mode and reverse-mode automatic differentiation as a built-in, first-class function in a functional programming language. Each of these constructs imposes only a small constant factor of the computational burden (time) of the function itself, and the forward construct has the same properties in terms of space. The functions can be applied to any function, including those involving derivatives and nested closures. | 03-19-2009 |

20140188543 | Optimized Bioresources and Bioprocessing - Provided is a system of hardware, software, and business methods for developing a management plan to optimize biomass resources for biochemical production. In particular, the method uses programming and resource data and information input from one or more resource sites to allow a manager to determine optimal allocations of biomass resources for pretreatment industry plants. | 07-03-2014 |
