Northridge, CA–The U.S. Patent Office has allowed the first two Universal Powerline Bus (UPB) patents from Powerline Control Systems.
The first is Application No. 09/656.160, “Zero Crossing Based Powerline Pulse Position Modulated Communication System,” and second, Application No. 09/879.874, “Synchronization/Reference Pulse-Based Powerline Pulse Position Modulated Communication System.” This communication method, which utilizes a PPM data encoding technique, was conceived six years ago by PCS CEO and chief design engineer, Marshall Lester, the inventor named on both patents. The patents will be assigned to Powerline Control Systems Inc., a California corporation.
These patents are the first in a series that are planned to protect the UPB technology that is currently being incorporated into various products being developed by PCS, UPB licensees and several companies involved in joint development projects. Due to its low cost and reliability, UPB technology is suited for command and control of appliances, lighting and lighting systems for applications in both the residential and commercial markets.
