  • Publication number: 20220014628
    Abstract: The example embodiments provides a processing system (10) including: an acquisition unit (11) that acquires target speech data in which a target speech is recorded or a target feature value that indicates a feature of the target speech; an inference unit (12) that infers a language of the target speech, based on an inference model for inferring a language of a speech from speech data or a speech feature value and the target speech data or the target feature value; a result output unit (13) that outputs an inference result by the inference unit (12); a determination unit (14) that determines whether the inference result is correct; and a learning data output unit (15) that outputs the inference result determined to be correct by the determination unit (14) and the target speech data or the target feature value, as learning data for generating the inference model.

  • Patent number: 9857852
    Abstract: Provided is a management control system for controlling the number of fan revolutions to avoid the number of fan revolutions likely to cause a high frequency of errors in a drive. The management control system includes: an error frequency calculating section for calculating a frequency of errors by acquiring the number of errors occurring in a drive and the number of fan revolutions, and then calculating the number of fan revolutions to avoid based on the frequency of errors; a storage section for storing the number of revolutions to avoid; and a fan revolution number controlling section for acquiring the number of fan revolutions and current ambient temperature in a housing, and controlling the number of fan revolutions within a revolution number range not including the number of revolutions to avoid stored in the storage section, depending on the ambient temperature.

  • Patent number: 9510476
    Abstract: A server includes a housing having a server-module storage space, a power source disposed in the rear side inside the housing, and a pair of server modules having horizontally symmetrical and vertically reversible shapes. When a pair of server modules is properly inserted into the housing of a server, they can receive electric power from the power source via connectors. Even when a pair of server modules is vertically reversed and inserted into the housing of a server, it is possible to secure electrical connection between the power source and the vertically reversed server modules. An erroneous insertion preventing measure is applied to the server-module storage space and a back panel fixed to a riser card, attached to each server module, so as to prevent erroneous insertion of server modules into the housing of a server. This may establish compatibility and standardization between server modules for use in servers.

  • Publication number: 20130279108
    Abstract: A server includes a housing having a server module dock, a power source disposed in the rear side inside the housing, and a pair of server modules having horizontally symmetrical and vertically reversible shapes.
