  • Patent number: 6937417
    Abstract: A disk drive device in which emergency unloading at the start of the engine is prevented, a head may have a prolonged life and improved reliability as an HDD is achieved. A disk drive device is driven or the movement of a magnetic head is allowed after an engine start in a vehicle is detected by an engine start detecting part, so that emergency unloading can be prevented at the start of the engine. In order to detect the engine start, voltage values on four power supply lines for a vehicle power supply device are monitored or the outputs of various sensors such as a tachometer, a vibration detection sensor, an engine sound detection sensor, a vehicle speed pulse, a gyro sensor and a parking brake are monitored. In another embodiment, the number of emergency unloading occurrence at the start of the engine is reduced, which allows the head to have a prolonged life, so that the disk drive device has improved reliability as an HDD.

  • Publication number: 20030216918
    Abstract: A voice recognition apparatus comprises a voice input device, a recognition processing device, a judging device and a setting device. The voice input device receives a voice input from a user. The recognition processing device performs a recognition processing to determine a plurality of word candidates corresponding to the voice input, through a matching processing with respective standby words in preset standby word groups. The judging device judges as whether or not the word candidates include a correct answer. The setting device determines a combination of most recognizable candidates in the word candidates and convertible word candidates thereof and sets same for the standby word groups to be used in a next recognition processing, in case where the judging device judges that the word candidate does not include the correct answer.
