Devore Ernest W, Irwin John W: Error detection and correction systems. International Business Machines Corporation, Somermeyer Herbert F, March 26, 1974: US3800281 (65 worldwide citation)

Plural error detecting and checking codes are used to check segmented data sets. A first error code checks each segment independently and has a first error correcting capability. Additionally, other error codes having a lesser error correcting capability verify proper correction of the segments on e ...

Beach Laurence R, Junge Bjarne, Zentgraf Henry J: Article handling and data retrieval. International Business Machines Corporation, Somermeyer Herbert F, August 20, 1974: US3831197 (53 worldwide citation)

Plural accessing means selectively store and fetch articles, preferably document-containing articles, from one of a large plurality of storage compartments. Transition zones are established between adjacent accessing means for facilitating transferring articles between assigned accessing zones. Such ...

Hong Se J, Patel Arvind M: Plural channel error correcting apparatus and methods. International Business Machines Corporation, Somermeyer Herbert F, February 25, 1975: US3868632 (50 worldwide citation)

Error correcting apparatus is provided for correcting plural channels in error in a parallel channel information system. The information is encoded in a cross-channel direction as well as along the channel length. The encoded message after storage or transmission is decoded in the cross-channel dire ...

Case Jerry R, Millican Donald L, Norton David E: SCR memory cell. International Business Machines Corporation, Somermeyer Herbert F, November 4, 1975: US3918033 (35 worldwide citation)

A bistable memory cell (stores one binary digit or bit) suitable for semiconductive memories includes a single SCR and a single transistor plus unique interconnections to provide a read-while-write array of such cells. The cell topology provides a small cell size with low stand-by power. The SCR pro ...

Dodd Paul D, Lynott John J, Treder John D: Continuously movable information storage and retrieval system. International Business Machines Corporation, Somermeyer Herbert F, May 7, 1974: US3809263 (31 worldwide citation)

A continuously moving information-bearing article carrier and a selectively actuated article handler are in peripheral velocity synchronism for exchanging information-bearing articles. Such dynamic article exchange occurs without stopping or altering the velocity of the carrier. In a preferred form, ...

McDonald Earl G, Patel Arvind M: Error detection systems. International Business Machines Corporation, Somermeyer Herbert F, January 15, 1974: US3786439 (17 worldwide citation)

Error detection is enhanced by using multiple independent error codes combined with nonlinear changes in the data field as applied to different error codes. Such nonlinear permutations increase the probability of detecting errors thereby maximizing the utilization of check bit redundancies. In a mag ...
