Title: David C. Crohn: Innovator in Data Line Systems
Introduction
David C. Crohn is a notable inventor based in Munich, Germany. He has made significant contributions to the field of data line systems, holding 2 patents that showcase his innovative approach to technology. His work primarily focuses on systems that enhance data integrity and error detection.
Latest Patents
One of his latest patents is a "System for determining loss of activity on a plurality of data lines." This system includes a flip-flop for each data line, with outputs connected to a NAND gate. The NAND gate is further connected through an OR gate to two output flip-flops in series. The logic of this system ensures that the output of the second flip-flop indicates whether data is present on all data lines or if one or more lines lack data.
Another significant patent is the "Frame error detection system," designed for SONET operations in both OC-3 and OC-12 modes. This system examines the incoming data bit stream to detect A1 and A2 bytes. In the OC-3 mode, if three consecutive A1 bytes are followed by three A2 bytes, the framing is deemed correct. If any of these bytes are missing, the system identifies an error in framing. The bytes are processed and stored in a series of flip-flops, with the output logic signal indicating the framing condition.
