Title: The Innovative Contributions of Harry A. Hennen
Introduction
Harry A. Hennen is a notable inventor based in Woodstock, IL (US). He has made significant contributions to the field of secure communication systems, holding a total of 3 patents. His work has been instrumental in enhancing the efficiency and security of data transmission.
Latest Patents
One of Hennen's latest patents is a secure communication system. This invention discloses a synchronous secure communication system wherein an information signal is encrypted in an encryption means. The encrypted signal is compressed to allow the insertion of a synchronization signal, and the combined signals are transmitted. At the receiver, the synchronization signal is extracted and used to synchronize the receiver to the incoming data stream, thereby improving receiver sensitivity and range. Another significant patent is a method and apparatus to detect and recover a pseudo-random sequence. This synchronization detector allows a portion of the received data stream to be parallel loaded into a sequence generating means. The sequence generating means provides a local synchronization sequence that is compared to the transmitted synchronization signal, and an error count is tallied. If the number of errors occurring in a predetermined 'window' is below a predetermined threshold, a synchronization detect signal is asserted. However, if the errors in a predetermined window exceed the threshold, the sequence generating means is reloaded with another portion of the received data stream, and the process is repeated until the synchronization detect signal is asserted.
Career Highlights
Harry A. Hennen has had a distinguished career, working at Motorola Corporation. His innovative work in secure communication systems has positioned him as a key figure in the industry. His patents reflect a deep understanding of the complexities involved in data transmission and synchronization.
