Title: Innovations of John S. Helton
Introduction
John S. Helton is a notable inventor based in Louisville, Colorado. He holds a total of 5 patents that showcase his contributions to technology and innovation. His work primarily focuses on data communication and optical transmission systems.
Latest Patents
One of his latest patents is an "Apparatus for insertion of overhead protocol data into a switched data." This invention provides two different sources for generating bytes to be inserted into frames of data communicated through a switching unit. The apparatus allows for the insertion of variable, programmable data patterns in multiple frames. Under the program control of a controller, the first source can selectively write data into designated time slots within designated rows and frames. Different data can be inserted into different rows of the same column of each frame, and the same data can be inserted into designated rows and columns of designated frames. The second source can write data into every row of a designated column of every frame.
Another significant patent is "Selection of transmission facilities using optical wavelength division." This invention describes a duplicated transmission system utilizing two optical wavelengths on each of a pair of optical links. One wavelength communicates data while the other designates the active optical link. The transmit units determine which optical link is active and transmit a signal on the second wavelength indicating this decision. The receive units select the active optical link based on the information received.
