Title: Method and apparatus for transmitting digital information and/or for recording and reproducing
IPC: H04N5/78
Filed: 1988-01-21
Abstract: In a method for digital information transmission and/or recording and reproduction, in which the data are converted in segments into digital signals, the word length of which is dependent on the information density of the data segments, there is the problem of redetecting the data segments in the event of faults. 
<??>The invention improves the method against susceptibility to faults, in that the digital signals obtained in segments are first allocated to blocks of a constant word length, subsequently the blocks, the data segments of which have a smaller word length than that predetermined by the blocks, are filled with portions of data segments of a word length greater than that predetermined by the blocks, and finally the data segments are recomposed in their original word length from the blocks.

the memory section for outputting the read-out information and associated 
error correction to second input of the error correction code 
generator/checker. A decoder is coupled to the error correction code 
generator/checker to receive the error code from the error correction 
code generator/checker and to generate a decoded signal. An error 
correction circuit is connected to receive an information portion of the 
read-out signal from the reading circuit so as to correct the received 
information on the basis of the decoded signal from the decoder. A 
control circuit is provided for maintaining the data input circuit in an 
active condition and the reading circuit and the decoder in an inactive

Title: Coalescing changes in pattern-directed, rule-based artificial intelligence production systems
IPC: G06F9/44
Filed: 1989-08-24
Abstract: A technique for collecting changes to working memory objects made by 
rule execution in an artificial intelligence production system avoids 
frequent use of a matching algorithm by delaying the match processing 
of the collected changes to a memory object until completion of an 
executing rule. A change to an object wrought by execution of a rule 
is signified in a control block for that object. Once a first change 
has occurred, subsequent changes caused before execution of the rule is 
complete will be made to the object and indicated by the change block. 
When execution of the rule is complete, the changes coalesced in the 
object itself are registered in the system by introduction of the 
changed object into the matching algorithm. This avoids match 
processing the object each time it is changed during execution of the 
rule.
