Abstract: PCT No. PCT/CH88/00067 Sec. 371 Date Dec. 5, 1988 Sec. 102(e) Date Dec. 5, 1988 PCT Filed Mar. 25, 1988 PCT Pub. No. WO88/07964 PCT Pub. Date Oct. 20, 1988.In twin-chamber compressed gas packs, the collar of a diaphragm which invaginates during motion in the container is secured with its opening region in a fold or in the upper part of the container, in order to provide the required sealing between product chamber and working fluid chamber. The disadvantage of packs of this type is that the use of multi-part containers is mandatory and/or that a support ring incorporated in the diaphragm produces a frictional force which may be large enough to prevent ejection of the feed material because of an insufficient pressure differential between the chambers. These drawbacks are overcome by securing the entire region of the collar to the internal wall of the casing.

Title: Method and system for recognition of broadcast segments
Inventor: ELLIS MICHAEL D
IPC: G06T7/00
Filed: 2000-07-12
Granted: 2004-05-06
Abstract: Broadcast segment recognition systems (10) and methods are provided in which a signature representing a monitored broadcast segment is compared with broadcast segment signatures in a data base (412) representing known broadcast segments to determine whether a match exists. Criteria for determining the validity of such a match are provided. In one aspect, signatures representing audio broadcast signals are formed by comparing temporally displaced portions of respective frequency band values within plural frequency bands of the broadcast audio signal. Systems and methods are provided for producing signatures representing intervals of a video signal which compensate for shifts in an edge of a picture (142) represented by the video signal. In addition, signatures characterizing respective intervals of a broadcast signal exhibiting correlation are produced by generating a difference vector (150) for each respective interval and carrying out vector transformations of the different vectors (150) to reduce such correlation. Moreover, signatures characterizing intervals of a video signal are produced with corresponding mask words representing reliability of values comprising the signature. Mask words of first and second signatures thus formed representing different portions of the video signal displaced from one another are compared to establish the values of the mask word. <IMAGE>

Abstract: A method for on-line restoration of redundancy information in a redundant array storage system. The invention provides alternative methods of restoring valid data to a storage unit after a Write failure caused by a temporary storage unit fault, in the first preferred method, a valid redundancy block is generated for the corresponding data blocks on all storage units. Resubmitting the interrupted Write operation causes the old (and potentially corrupted) data block to be "subtracted" out of the re-computed redundancy block. The uncorruted new data block is written over the old data block, and is "added" into the re-computed redundancy block to create a new, corrected redundancy block. The new, corrected redundancy block is written to the appropriate storage unit, in the second preferred method, a new redundancy block is generated from all valid data blocks and the new data block. The new redundancy block and the new data block are then written to the appropriate storage units. In both cases, the entire method is done on-line, with insignificant interruption of normal operation of the redundant array system, and without requiring added processing during normal operation.
