  • Patent number: 7953491
    Abstract: Audio streaming is made available throughout the signal processing path of the speech processor of a cochlear implant or other audio signal processor. Audio streaming comprises the digitally phase locked playback of a real time n-bit digital audio stream, where n may be a large number, e.g., 8, 12, 16, 24 or 32, that emanates (unsolicited) from an operating speech processor. A number of sample points are made available long the processing chain of a digital signal processor (DSP) used within the speech processor of the cochlear implant. Audio streaming may occur at any sample point. The signal at a selected sample point may be selectively monitored in order to allow appropriate diagnostics to be performed. Audio streaming utilizes an auto-referencing mixed-mode phase locked loop. Such phase locked loop processes an asynchronous stream of digital audio samples that arrive at a designated location, e.g., a selected sample point, at a consistent, but unknown, average rate.

  • Patent number: 7937155
    Abstract: An envelope based amplitude mapping achieves the signal compression required to provide a natural sound level without the high processor loading or waveform alteration. In one embodiment, the output of a family of parallel bandpass filters is processed by an envelope detector, followed by decimation. The resulting reduced data rate envelope is log mapped to produce a scaling factor for the original high data rate bandpass filter output sequence. The resulting scaled signal determines the current level for stimulation of the cochlea for each frequency band, which stimulation achieves a log mapping of the sound amplitude effect similar to natural hearing, while reducing processor load, and preserving waveform shape.

  • Patent number: 7933657
    Abstract: Alternative stimuli, i.e., stimuli other than the constant amplitude stimuli used in prior fitting schemes, are used to set the parameters of a cochlear implant system. The use of such alternative stimuli allows the entire fitting process to be completed in a very short time period, and generally eliminates the need for secondary adjustments. In one preferred embodiment, the alternative stimuli comprise white noise that is internally generated within the speech processor.

  • Patent number: 7835800
    Abstract: An adaptive place-pitch ranking procedure for use with a cochlear implant or other neural stimulation system provides a systematic method for quantifying the magnitude and direction of errors along the place-pitch continuum. The method may be conducted and completed in a relatively short period of time. In use, the implant user or listener is asked to rank the percepts obtained after a sequential presentation of monopolar stimulation pulses are applied to a selected spatially-defined electrode pair. The spatially-defined electrode pair may be a physical electrode pair or a virtual electrode pair. A virtual electrode pair includes at least one virtual electrode contact. Should the patient's judgment of pitch order be correct for all applied interrogations, then no further testing involving the tested electrode pair (two electrode contacts) is undertaken.

  • Patent number: 7818066
    Abstract: A hand-held remote unit functions as both a remote status device and a control device for a cochlear implant system. When placed near the headpiece of a cochlear implant system, the remote unit monitors the forward telemetry signals transmitted between an external sound processor, e.g., a behind-the-ear (BTE) sound processor, and an implanted unit, thereby providing the remote unit with the ability to output status information regarding the implant system. The remote unit may also generate a back telemetry signal that when properly received by the sound processor causes a forward telemetry signal to be generated that controls the implant unit.

  • Patent number: 7636603
    Abstract: A bionic ear cochlear stimulation system has the capability to stimulate fast enough to induce stochastic neural firing, thereby acting to restore “spontaneous” neural activity. Such neurostimulation involves the use of a high rate pulsitile stimulation signal that is amplitude modulated with sound information. Advantageously, by using such neurostimulation, a fitting system may be utilized that does not normally require T-level threshold measurements. T-level threshold measurements are not required in most instances because the high-rate pulsitile stimulation, even though at levels that would normally be a sub-threshold electrical stimulus, is able to modulate neural firing patterns in a perceptible way.

Should the patient's judgment of pitch order be correct for all applied interrogations, then no further testing involving the tested electrode pair (two electrode contacts) is undertaken. However, should there be errors in the place-pitch ranking, which errors evidence perceptual place-confusions, then a search is undertaken for the spread of the perceptual confusion by separating the target channel and competing channel by one electrode contact at a time.

  • Patent number: 7295878
    Abstract: An implantable medical device, such as an implantable pulse generator (IPG) used with a spinal cord stimulation (SCS) system, includes a rechargeable lithium-ion battery having an anode electrode with a substrate made substantially from titanium. Such battery construction allows the rechargeable battery to be discharged down to zero volts without damage to the battery. The implantable medical device includes battery charging and protection circuitry that controls the charging of the battery so as to assure its reliable and safe operation. A multi-rate charge algorithm is employed that minimizes charging time while ensuring the battery cell is safely charged. Slow charging occurs at lower battery voltages (e.g., battery voltage below about 2.5 V), and fast charging occurs when the battery voltage has reached a safe level (e.g., above about 2.5 V). When potentially less-than-safe very low voltages are encountered (e.g., less than 2.

  • Patent number: 7292891
    Abstract: A system for allowing bilateral cochlear implant systems to be networked together. An adapter module that forms part of the system allows two standalone BTE units to be synchronized both temporally and tonotopically in order to maximize a patients listening experience. The system further allows a peer-to-peer network and protocol that includes two BTE units during normal operation, or two BTE units plus a host controller (PC, PDA, etc. . . . ) during fitting. The bilateral cochlear network includes four main components: (a) a communications interposer adapted to be inserted between the BTE battery and the BTE housing or modified BTE devices; (b) a communication channel over which communication takes place between the connected devices, including the protocol governing access to such channel; (c) the synchronization mechanisms used to achieve synchronization between the connected devices; and (d) a bilateral fitting paradigm.

  • Patent number: 7251530
    Abstract: Errors in pitch (frequency) allocation within a cochlear implant are corrected in order to provide a significant and profound improvement in the quality of sound perceived by the cochlear implant user. In one embodiment, the user is stimulated with a reference signal, e.g., the tone “A” (440 Hz) and then the user is stimulated with a probe signal, separated from the reference signal by an octave, e.g., high “A” (880 Hz). The user adjusts the location where the probe signal is applied, using current steering, until the pitch of the probe signal, as perceived by the user, matches the pitch of the reference signal, as perceived by the user. In this manner, the user maps frequencies to stimulation locations in order to tune his or her implant system to his or her unique cochlea.
