  • Publication number: 20170359659
    Abstract: A method, including capturing first sound with a hearing prosthesis, classifying the first sound using the hearing prosthesis according to a first feature regime, capturing second sound with the hearing prosthesis, and classifying the second sound using the hearing prosthesis according to a second feature regime different from the first feature regime.

  • Publication number: 20170171674
    Abstract: Disclosed herein are methods, systems, and devices for selecting a scene classification for the operation of a sensory prosthesis, such as a hearing prosthesis. A system of two or more sensory prostheses can receive respective inputs from the environment of a recipient. A scene classification can then be determined for each sensory prosthesis based on the audio input received by each hearing prosthesis. A confidence value can also be determined for each scene classification. A scene classification can then be selected for each sensory prosthesis, from the determined scene classifications, based on the determined confidence values. Such operation can allow each sensory prosthesis to operate according to a respective selected scene classification that could be the same or that could be different from scene classifications selected for other sensory prostheses of the system.

  • Patent number: 8238169
    Abstract: A method and apparatus for selectively restoring data in a non-volatile memory array based on failure type. Weakened data and erroneous data are identified by performing two readings of a specific memory section. Alternatively, an error correction code is used after a first reading of data to identify erroneous data. The manner in which data is restored will depend on whether the data changed because of an erase failure or a program failure. If only a program failure occurred then the data will be reprogrammed without an intervening erase step. If the data experienced an erase failure, then the data will be erased prior to being programmed with correct data.

  • Publication number: 20120197992
    Abstract: A customizable communication, storytelling and learning environment with a storyline or flow path with one or more plots and/or subplots and story branch or transition points and one or more endings for individuals and groups that is delivered with various media, over various media channels, at various times and intervals by use of a triggered communications server and method and producer development kit therefor.

  • Patent number: 8161355
    Abstract: A method for selectively refreshing data in a nonvolatile memory array based on failure type detected by an error correction code. If the page is determined to be error-free, no refresh operation takes place. Otherwise, if single-error words on a page contain erased and programmed bit errors, then a refresh operation, consisting of an erase and program, takes place. The erase operation is skipped if single-error words on a page solely contain a program failure.

  • Patent number: 8081521
    Abstract: A memory circuit for holding a single binary value. A first bit cell holds one of a logical high value and a logical low value, and a second bit cell also holds one of a logical high value and a logical low value. Circuitry is provided for placing a logical high value in the first bit cell when the binary value in the memory circuit is to be a logical high value, and circuitry is provided for placing a logical high value in the second bit cell when the binary value in the memory circuit is to be a logical low value. In this manner, a logical high value exists within the memory circuit, whether the single binary value within the memory circuit is a logical high value or a logical low value. The difference between the two values of the binary value is which of the two bit cells holds the logical high value. Thus, this memory circuit can be sensed without the use of a sense amplifier.
