Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
51 words
A digital hearing enhancement devide, comprising means for converting an input signal into a plurality of separate bands of frequency signals, and means for operating upon said frequency signals to alter said frequency signals in accordance with a non-linear model of the hearing characteristic of the individual hearing enhancement device user.
Claim 2
Dependent Claim
51 words
A digital hearing enhancement devide, comprising means for converting an input signal into a plurality of separate bands of frequency signals, and means for operating upon said frequency signals to alter said frequency signals in accordance with a non-linear model of the hearing characteristic of the individual hearing enhancement device user.
Claim 3
Dependent Claim
15 words
The device recited in claim 1 wherein, said means for operating includes noise suppression means.
Claim 4
Dependent Claim
15 words
The device recited in claim 1 wherein, said means for operating includes feedback suppression means.
Claim 5
Dependent Claim
17 words
The device recited in claim 1 wherein, said means for converting includes a plurality of filter devices.
Claim 6
Dependent Claim
16 words
The device recited in claim 4 wherein, each of said filter devices comprise band pass filters.
Claim 7
Dependent Claim
22 words
The device recited in claim 1 wherein, said model is designed to be the inverse of the hearing characteristic of said individual.
Claim 8
Independent Claim
36 words
A method of enhancing the hearing capability of a person, comprising the steps of: testing the person to ascertain a hearing characteristic, and providing a hearing enhancement device which is specifically designed to match said characteristic.
Claim 9
Independent Claim
36 words
A method of enhancing the hearing capability of a person, comprising the steps of: testing the person to ascertain a hearing characteristic, and providing a hearing enhancement device which is specifically designed to match said characteristic.
Claim 10
Dependent Claim
25 words
The method recited in claim 7 wherein, said characteristic is established in a particular environment so as to enhance the hearing capability within said environment.
Claim 11
Dependent Claim
93 words
A transmultiplexer for use with a hearing enhancement device comprising, a bank of band pass filters, noise suppression means, feedback suppression means, frequency compensation means, recruitment means, and recombiner means, . said noise suppression means, feedback suppression means, frequency compensation means, and recruitment means connected together in series between said bank of band pass filter means and said recombiner means whereupon an input signal which was filtered into a plurality of signal bands is recombined at said recombiner means into a single output signal after being operated upon by the series connected components.
Claim 12
Dependent Claim
93 words
A transmultiplexer for use with a hearing enhancement device comprising, a bank of band pass filters, noise suppression means, feedback suppression means, frequency compensation means, recruitment means, and recombiner means, . said noise suppression means, feedback suppression means, frequency compensation means, and recruitment means connected together in series between said bank of band pass filter means and said recombiner means whereupon an input signal which was filtered into a plurality of signal bands is recombined at said recombiner means into a single output signal after being operated upon by the series connected components.
Claim 13
Dependent Claim
73 words
A transmultiplexer for use with a hearing enhancement device comprising, input signal filtering means time to frequency transform means connected to receive filtered signals from said input filtering means, signal processing means connected to receive TFT transformed signals from said TFT means, Frequency to time transform (FTT) means connected to receive processed signals from said signal processor means, and output filtering means for receiving FIT transformed signals and producing a recombined output signal.
Claim 14
Dependent Claim
73 words
A transmultiplexer for use with a hearing enhancement device comprising, input signal filtering means time to frequency transform means connected to receive filtered signals from said input filtering means, signal processing means connected to receive TFT transformed signals from said TFT means, Frequency to time transform (FTT) means connected to receive processed signals from said signal processor means, and output filtering means for receiving FIT transformed signals and producing a recombined output signal.
