Patent EP-0746133-A2 (EP)
Inventor: SHAW DAVID GOODWIN
IPC: G10L21/0208

Abstract: Acoustic echos are canceled by employing a first echo canceler having a comparatively long first impulse response synthesis capability which is connected between a transmit path and receive path for generating a first error signal and for canceling echo signals in the transmit path, and at least a second echo canceler having a comparatively short second impulse response synthesis capability connected in parallel with the first echo canceler between the transmit and the receive path. The second echo canceler is supplied with the first error signal from the first echo canceler and is adaptively operating simultaneously with but independent of the first echo canceler to further cancel echos in the transmit path. Specifically, the first echo canceler is intended to capture the substantially stationary and any slowly varying components of the echo path impulse response, and the second echo canceler is intended to capture the more time varying, i.e., dynamically varying, component of the echo path impulse response. I have recognized that in certain applications, the more time varying component of the echo path impulse response may exist in a relatively short time interval. For instance, in the canceling of acoustic echos, the most time variation in the echo path impulse response results from the movement of objects and/or persons near either the microphone or the loudspeaker. This movement results in significant changes in the early portion of the echo path impulse response. Aligning the tap coefficients of the second echo canceler with this early portion of the echo path impulse response provides significantly enhanced echo cancelation performance over that achievable with only the first echo canceler. This is realized by placing a "short" fixed delay in series with the receive path signal to the second echo canceler. In other applications, the time varying component of the echo path impulse response still exists in a relatively short time interval, but the time varying component relative to the overall echo path impulse response may change with time or may not be known a priori. Under these circumstances, it is desirable to dynamically align the coefficients of the second echo canceler over the echo path impulse response. This is realized by employing a dynamically adjustable delay in series with the receive path to the second echo canceler. In one embodiment, the delay value is dynamically generated in response to the tap coefficient values of the first echo canceler.

Abstract: The call-waiting feature is supported on voice-and-data modems (22,25) by causing voice-and-data modems to go into voice-only mode upon receipt of the modem clear-down signal (352-354). A first voice-and-data modem (22) engaged in an initial voice-and-data call with a second voice-and-data modem (25) responds to receipt of a call-waiting signal by generating a replica of the call-waiting signal on the user's audio channel. The first modem responds to a user request (300) to pick up the waiting call by sending (306) the modem clear-down signal to the second voice-and-data modem, going (312) into voice-only mode, and transmitting (314) a waiting-call acceptance signal. The initial call that is placed (332) on hold is thus a voice-only call. While in a voice-plus-data picked-up waiting call, the first modem responds to a user request to reinstate the initial call by again sending the modem clear-down signal, going into voice-only mode, and transmitting a call-resumption signal. The first modem is thus in voice-only-mode when it is re-connected to the initial, voice-only, call. The re-connected initial call may now be re-converted into a voice-plus-data call in the conventional manner.

The disc drive is provided with vibration absorbing members for suppressing transmission of vibration caused by high speed rotation of the disc from the main body to the casing. The vibration absorbing members are formed of elastical members and they are arranged between the side portions of the main body and the inside of the casing, thereby the main body is supported by the casing through the vibration absorbing members to prevent vibrations caused in the main body from being transmitted to the casing. Further, the casing has a U-shaped side plate and a top plate fixed to the side plate by screws, in which the top plate is in point contact with the side plate through a plurality of protrusions formed on upper edges of the side plate. This point contact between the top plate and the side plate makes it possible to prevent rattling from being caused by the transmitted vibrations, thereby preventing generation of noise.

Abstract: An apparatus for decoding coded video data is provided which is capable of decreasing the storage size of its frame memory while attenuating the drift noise and minimizing lowering of the resolution during the reconstruction of the coded video data. 
     The apparatus comprises a data size reducing means for reducing the size of a decoded video data reconstructed by subsampling, pixel differential coding, or other means, a frame memory for saving a reduced video data released from the data size reducing means, and a data size recovering means for recovering the original size of the decoded video data from the reduced data saved in the frame memory. Accordingly, the storage size of the frame memory is decreased by a combination of compression of pixel data and IDCT processing in a reduced block size and will successfully attenuate unwanted drift noise and minimize declination of the resolution.

Abstract: A method, apparatus, and computer-usable medium for compressing data in a file system utilizing the concept of "holes". A mapping table in a file system maps the logical blocks of a file to actual physical blocks on disk where the data is stored. Blocks may be arranged in units of a cluster, and the file may be compressed cluster-by-cluster. Holes are used within a cluster to indicate not only that a cluster has been compressed, but also the compression algorithm used. Different clusters within a file may be compressed with different compression algorithms. A unit of data is compressed, with the result that the file occupies fewer physical blocks than it has logical blocks. The mapping table is updated to indicate that for a given unit of data compressed, fewer physical blocks are needed. Certain logical blocks belonging to this unit of data are not mapped to physical blocks but are mapped to a hole. A hole indicates that the unit of data was compressed, and may also indicate the particular compression algorithm used to compress the unit of data. If a unit of data begins or ends within the middle of a cluster, to avoid overwriting the data not to be changed the whole cluster must first be read from disk. If a hole indicates the cluster had been compressed, the data must be expanded first. The cluster is read into a buffer and the portion to be changed is overwritten. The cluster is compressed and written back to disk. Those clusters within which the unit of data neither begins nor ends may be written to directly.
