Jon M Semerau is a notable inventor based in Maplewood, MN (US). He has made significant contributions to the field of data communication technology, holding 2 patents that showcase his innovative approach to multiplexing and data synchronization.

Latest Patents

One of his latest patents is the "Multiplexing Character Processor." This invention multiplexes data characters to and from multiple communication lines to a Central Processing Unit by bit slicing. The input data present on these communication lines is sampled at a rate that is at least 16 times the data bit rate, formulated as a serial data bit stream. Each sample corresponds to a time slice allocated to a specific communication line under the control of a scan list. This design allows for high data rate communication lines to be placed on the scan list multiple times, ensuring accurate data reproduction. Character assembly and disassembly are performed in an arithmetic logic unit (ALU) under program control, providing the flexibility to support various communication link protocols. The input data on each communication line may have different protocols, and synchronization of the serial data bits to the communication lines is managed by a data bit synchronizer.

Another significant patent is the "Data Bit Synchronizer." This device is particularly adapted for use with a multiplexing character processor that multiplexes data characters to and from various communication lines. The data bit synchronizer operates with communication lines carrying different protocols and data bit rates. A RAM memory stores control and status information for each communication line, accessed at a rate corresponding to the multiplexing rate. This ensures the repeated output of information associated with each communication line. Additionally, the data bit synchronizer incorporates a bit rate clock generator for generating timing signals corresponding to selectable output data rates, utilizing a multiplexer to multiplex these timing signals with control and status information.
