  • Patent number: 7304471
    Abstract: A combined sensor and bearing assembly (1) of the present invention includes a rolling bearing unit (22) and a rotation sensor unit (23). The rolling bearing unit (22) includes a rotatable raceway member (2), a stationary raceway member (3) mounted around the rotatable raceway member (2) with an annular bearing space defined between it and the rotatable raceway member (2), and a circular row of rolling elements (4). The combined sensor and bearing assembly (1) also includes a to-be-detected member (7) including a magnet secured to the rotatable raceway member (2), and a magnetic detector (8) including a magnetic sensor of an analog output type disposed in face-to-face relation with the to-be-detected member (7).

  • Patent number: 7169999
    Abstract: Audio control data extracted from SMF data by a data decoder section is supplied to an audio decoder section. The audio decoder section receives the audio control signal and generates a tone as an audio output in accordance with the audio control signal. If the decoding period by the audio decoder section is sufficiently short, the performance tone and the audio output create synchronized sounds because the audio control signal is decoded from a Meta event of the SMF data.

  • Publication number: 20060198518
    Abstract: The present invention is relative with an information processing method for carrying out processing unit data in which one contents are handled as a data unit. When contents data are to be reproduced/output in succession, the tamper check processing for the next contents data, reproduced next to current contents data, being reproduced, is commenced at timing following the end of the processing of decryption and/or demodulation for the current contents data. This eliminates the time interval during which the processing of decryption/demodulation for the current contents data and the tamper check processing for the next contents data are carried out simultaneously in parallel to prevent the processing load caused by concurrent execution of the tamper check processing and the processing of decryption/demodulation from increasing.
