Title: "c" program source blocker
Inventor: GUSENIUS DELMAR J
IPC: G06F9/44
Filed: 1990-03-01
Abstract: ABSTRACT OF THE DISCLOSURE    A  programming  tool for  providing  a  graphical representation of the relationships among a plurality of nested blocks integrated into a processed "C" source code listing is disclosed.  For each line of code including a "(" character, an outbound arrow is appended.  Similarly, for each  line  of code  including a  ")" character,  an inbound arrow is appended, and the inbound and outbound arrows are tabbed into vertical alignment.   A  "depth number" is developed for each line now having arrows by performing an increment when a line having an outbound arrow is encountered and a decrement for the starting depth number value of the next line when a given line having  an  inbound  arrow  is  encountered.    The  depth numbers, and also one or more (as indicated by the depth number for a given line) right justified vertical line segments, are appended to the lines having outbound or inbound arrows.   Intermediate lines have appended the same number of vertical line segments as the last arrowed line if it was outbound or one less than the last arrowed line if it was inbound.   Then, horizontal line segment characters are entered in the spaces between the depth number and the leftmost vertical line segment in a given line having an outbound or inbound arrow.

Title: Time-division multiplex communication system with a synchronizing circuit at the receiving end which responds to the coding of words inserted in the transmitted information
Inventor: WEIS BERND X
IPC: H04L5/22
Filed: 1990-07-03
Abstract: There are TDM communication systems in which synchron-ization is accomplished by means of code words which are transmitted at regular time intervals and coded in a particular code. In systems where the signals are trans-mitted in packets of uniform length, each of the code words contains the information of the so-called header of a packet. The checking device according to the inven-tion successively checks all n-bit bit groups (Xj to Xj+n-1) beginning with any one (Xj) of the successive bits of the received bit sequence as to whether they are coded in a particular code. This is done by calcu-lating the syndrome (S1 to Sn-k) in several networks (N1 to Nn-k) which operate in parallel and each of which calculates one syndrome component. The received bit se-quence is delayed until the networks have calculated the syndromes for a given n-bit bit group and until a syndrome evaluation circuit (LS) indicates whether the bit group is a code word.
