Title: The Innovative Contributions of Dennis F Johnson
Introduction
Dennis F Johnson is a notable inventor based in Winnipeg, Canada. He has made significant contributions to the field of radio communication networks, particularly in the context of utility meter data collection. With a total of 8 patents to his name, Johnson's work has had a substantial impact on automatic meter reading systems.
Latest Patents
One of Johnson's latest patents is a radio communication network designed for collecting data from utility meters. This innovative system allows for the transmission of data from multiple remote stations to a central station. The design includes an array of receiving stations that ensure messages from each remote station can be received by at least two, and preferably four, receiving stations. This redundancy provides a high level of message duplication, which is crucial for reducing message loss. The remote stations transmit utility usage information obtained from a previous time period at random times, allowing for message collisions to occur. Additionally, a quiet period can be implemented during which remote stations are prevented from transmitting, facilitating communication between the receiving stations and the central station.
Another significant patent by Johnson is a wide area communications network for remote data generating stations. Similar to his previous work, this system is aimed at automatic meter reading systems and incorporates the same principles of redundancy and message duplication to enhance data transmission reliability.
Career Highlights
Throughout his career, Johnson has worked with several prominent companies, including Itron GmbH and Iris Systems Inc. His experience in these organizations has allowed him to refine his expertise in radio communication technologies and their applications in utility management.
