  • Patent number: 8057040
    Abstract: Upon detecting a selection of an examination start button, a start and completion management unit starts an examination. The control unit switches an observation state to an infrared light observation by an observation switching unit. Next, an examiner performs alignment while observing an eye to be examined, and photographs the eye to be examined with a photographing unit. The start and completion management unit determines whether the examination is completed according to a selection of an examination complete button, and repeats the alignment until it is determined that the examination is completed.

  • Patent number: 7099824
    Abstract: A user dictionary, which is formed by storing pronunciations and notations of target recognition words designated by the user in correspondence with each other, input speech recognition data, and dictionary management data used to determine the recognition field of a recognition dictionary used in recognition of the speech recognition data are sent to a server via a communication module. In the server, a dictionary management unit looks up an identifier table to determine a recognition dictionary corresponding to the dictionary management information received from a client from a plurality of kinds of recognition dictionaries. A speech recognition module recognizes the speech recognition data using at least the determined recognition dictionary. The recognition result is sent to the client via a communication module.

  • Patent number: 7058580
    Abstract: The system implements high-accuracy speech recognition while suppressing the amount of data transfer between the client and server. For this purpose, the client compression-encodes speech parameters by a speech processing unit, and sends the compression-encoded speech parameters to the server. The server receives the compression-encoded speech parameters, a speech processing unit makes speech recognition of the compression-encoded speech parameters, and sends information corresponding to the speech recognition result to the client.
