Abstract: 1,179,448. Automatic exchange systems. INTERNATIONAL BUSINESS MACHINES CORP. 9 June, 1967 [21 June, 1966], No. 26662/67. Addition to 1,115,520. Heading H4K. The path seeking apparatus of the parent Specification is modified as a result of a more economical expression of the logical functions employed; the logic circuits which examine path co-ordinates, in search of conflict between existing paths and proposed paths, are consequently simplified considerably.

Abstract: Provided is a method, system, and program for providing synchronization in a binary data stream. A binary data stream is received. A synchronization mark having at least one isolated peak is generated into at least one point in the data stream. An encoded data stream is formed by concatenating the synchronization mark with the received binary data. During decoding, the synchronization mark is detected based on error propagation occurring adjacent to the at least one isolated peak of the synchronization mark.

Abstract: A pulse signal conditioner filters and equalizes signal pulses representing digital data whether or not obtained from a magnetic recording device. Modified low pass filters filter (23, 25) the pulse signals and also derive and feed forward the second time derivative of the filtered pulse signals. The filtered pulse and the second time (234, 254) derivative thereof are combined to (230, 250) slim the pulse. Further slimming is provided by delay line equalizers (27, 29) having three paths. A first path (271) for attenuating the pulse signals, a second path (272) for delaying the pulse signals for a first delay, and a third path (273-274) for delaying the pulse signals for a second delay and attenuation. Pulse signals from the three paths are combined (270) to further slim the pulse.
