  • Patent number: 11235149
    Abstract: Optogenetic signal processing is described for an auditory prosthesis with an intracochlear array of optical stimulation sources implanted in a patient having auditory neurons genetically modified with light sensitive ion channels. Stimulation timing signals are generated for the corresponding auditory neurons for each band pass signal based on characteristic temporal fine structure features of the band pass signals. The stimulation timing signals include: i. one or more channel opening signals adapted to open the ion channels of the corresponding auditory neurons, and ii. one or more channel closing signals adapted to close the ion channels of the corresponding ion channels. Optical stimulation signals are then produced for the optical stimulation sources based on the stimulation timing signals.

  • Publication number: 20220008722
    Abstract: Arrangements are described for fitting an implanted patient and a hearing implant system having an implanted electrode array of electrode contacts. Objective response measurements are performed following delivery of preliminary electrical stimulation signals to the electrode contacts to determine a preliminary fit map that characterizes preliminary patient-specific operating parameters for the hearing implant system. Then an adjusted fit map is produced that characterizes adjusted patient-specific operating parameters for the hearing implant system based on using the preliminary fit map to constrain an implant neural response model to best fit a normal hearing neural response model.

  • Patent number: 11184719
    Abstract: A signal processing arrangement generates optical stimulation signals to optical stimulation contacts in an implanted cochlear implant array. An input sound signal is transformed into band pass signals that each represent an associated band of audio frequencies, with each band pass signal includes an envelope component characterizing loudness of the band pass signal, and a fine structure component characterizing temporal details of the band pass signal. One or more of the signal components of each band pass signal is half wave rectified to remove negative phase signals. Signal slope is determined that corresponds to rate of change of the rectified one or more signal components. Then constant-rate optical stimulation pulses are generated for one or more given band signals only when the rectified one or more signal components has a positive signal slope.

  • Publication number: 20210303523
    Abstract: An illustrative data storage system is configured to replicate, from a source storage system to a target storage system, a pod that includes a file system constructed of block objects. The pod may be a storage system construct that groups storage entities within a namespace and supports operations on the storage entities as a group. The block objects may store metadata for individual files and directories of the file system and may support random read-write access to blocks of data associated with the files and directories of the file system.

  • Publication number: 20210303522
    Abstract: An illustrative data storage system is configured to use pods to efficiently copy files systems constructed of block objects. In certain examples, the storage system generates, based on a pod that includes a file system constructed of block objects, a virtual copy of the pod such that modifications made to the pod (e.g., modifications to contents of the block objects by way of the pod) after the generation of the virtual copy of the pod are distinct from the virtual copy of the pod. In certain examples, the virtual copy of the pod is a writeable clone of the pod and modifications made to the clone (e.g., modifications to contents of the block objects by way of the clone) after the generation of the clone are distinct from the pod.

  • Publication number: 20210303519
    Abstract: An illustrative system is configured to optimize a transfer of a file system from a source storage system to a target storage system. For example, the system, in association with the transfer, determines that a copy of a collection of blocks containing data of block objects of the file system is already stored at the target storage system. In certain examples, an identifier referencing the collection of blocks is shared by the source and target storage systems and is used to determine that the copy of the collection of blocks containing data of block objects of the file system is already stored at the target storage system. The system uses the copy of the collection of blocks already stored at the target storage system instead of transferring the collection of blocks from the source storage system to the target storage system as part of the transfer.

  • Publication number: 20200038659
    Abstract: A bilateral hearing implant system has a left side and a right side. Left and right side filter bank pre-processors preprocess left and right microphone signals to generate band pass signals for each side. A bilateral signal processing arrangement processes the band pass signals in a time sequence of stimulation frames. The signal processing module includes a bilateral channel selection module synchronously selects for each stimulation frame a set of stimulation channels for each side based on spectral content of the band pass signals. Left and right side signal processing submodules process for each stimulation frame a limited subset of each side band pass signals corresponding to the selected stimulation channels to generate electrical stimulation signals.

  • Patent number: 10300274
    Abstract: A signal processing arrangement generates electrode stimulation signals to stimulation contacts in a cochlear implant electrode array. A signal filter bank transforms an input sound signal into band pass signals, which each represent an associated frequency band of audio frequencies. An envelope processing module processes the band pass signals in a sequence of sampling time frames, wherein for each time frame, the processing includes calculating for each band pass signal at least one signal envelope dynamic property that is changing during the time frame. A channel selection module selects one or more of the band pass signals for each time frame based on the dynamic properties to produce the electrode stimulation signals to the stimulation contacts.

  • Patent number: 9919155
    Abstract: A method is described for delivering stimulation signals in an implantable multichannel neuro-stimulating device such as a cochlear implant. A stimulation channel is selected for delivering a data stimulation signal. One or more desensitization channels spatially adjacent to the stimulation channel are also selected. One or more non-data desensitization signals are delivered on the desensitization channels during a desensitization period before delivery of the data stimulation signal, and then the data stimulation signal is delivered on the stimulation channel. The stimulation channel may be blanked to prevent stimulation signals during a sensitization period before delivering the data stimulation signal.
