| 20100205676 | PROCESSING OF DATA INFORMATION IN A SYSTEM - Data information, represented by electric or wave signals, or data information within the artificial or natural databases and storage media, such as for example DNA, encoded as a sequence of symbols, is, for the purpose of its concealing and simultaneously preserving its select local data information segments, partitioned within a physical medium, such as especially computer hardware, physical communication channel, physical storage medium or biological material, into short overlapping data segments. The studied local data information segments are contained within the short segments in their entirety. These partitioned short segments constitute the first group and to at least one short segment of the first group, data, encoded as selected symbols, are pre-pended or appended, to the symbols of the short segments of the first group. The resulting mixture of segments is interconnected into a sequence of data. The entire process may be repeated multiple times. | 08-12-2010 |

| 20120128164 | BINAURAL NOISE REDUCTION - In one embodiment, the present invention provides a sound processing device with a binaural input and binaural output, where “binaural input” means at least one microphone mounted in or near each ear of the device user, and “binaural output” means at least one output signal directed to each ear. The device may be comprised of two parts connected by a wired or wireless link. The device comprises: at least one microphone in or near each ear for the transduction of the sound at each ear; a signal-to-noise estimation module to estimate the signal-to-noise ratio present at each ear; a comparison and selection module to compare the signal-to-noise ratios present at the two ears and select the ear with the greater signal-to-noise ratio; a noise reduction control module that uses the spectral and temporal information from the selected ear signal to control two identical noise reduc tion modules; two identical noise reduction modules that process the signals from the two ears, under the control of the control module; and two output modules that amplify the output signals from the noise reduction modules appropriately for each ear and present the amplified signals as sound or other signals to each ear of the device user. The device may be implemented in dedicated hardware embodiment or by software running on a microprocessor. | 05-24-2012 |

| 20090018615 | INCREMENTAL STIMULATION SOUND PROCESSOR - In one aspect of the invention, a cochlear implant constructed and arranged to successively generate stimulation signals each comprising at least one stimulus pulse such that said successive stimulation signals incrementally build a neural excitation pattern that accurately reflects a received sound. In one embodiment, each said successive stimulation signal is generated based on the cumulative effect of all previous stimulus pulses, thereby compensating for finite spatial spreading of individual stimulus pulses as well as for the temporal integration of the neural excitation pattern along the neural pathways. | 01-15-2009 |

| 20100062713 | HEADSET DISTRIBUTED PROCESSING - Distributing signal processing for a headset. The system comprises a headset and base device. The headset has one or more microphones, and one or more speakers. The headset communicates with the base device via a bidirectional wireless communications link such as Bluetooth. The headset has an on-board digital signal processor for processing at least one of electrical signals passing to the speaker and electrical signals passing from the microphone. The base device has a processor which can carry the burden of any or all processing functions which do not require short latency. And/or the base device's processor can control at least one aspect of digital signal processing of the digital signal processor of the headset, and effect such control via the wireless communications link. | 03-11-2010 |

| 20090161896 | METHOD AND APPARATUS FOR ENVELOPE DETECTION AND ENHANCEMENT OF PITCH CUE OF AUDIO SIGNALS - A method and apparatus for detecting an envelope of an audio signal, and a method and apparatus for enhancing the pitch cue of an audio signal perceived by a cochlear implant patient where the audio signal is processed and input to an implant device of the recipient. The methods and apparatuses use techniques such as filtering, rectifying, detecting peak values, sampling, resetting, comparing and multiplying various signals to detect the envelope or enhance the pitch cue of the audio signal. | 06-25-2009 |
