Self-Tuning Transmitter Technology Patent Awarded

Van Nuys, CA -- Terocelo Inc. announced that it has been awarded a patent for its self-tuning output digital filter for direct conversion delta-sigma transmitter by the U.S. Patent and Trademark Office. The patent number is 7,236,112. This patent protects a key innovation of the company's transmitter chip design, which eliminates a number of discrete, inflexible components required by other wireless transmitters. The invention is already implemented in the company's Lycon family of chips. The Lycon chips contain the company's patented True Software Radio technology and make it possible for wireless communications devices to reconfigure automatically solely by software programming.

Commenting on the new patent, Antonio Turgeon, Chairman of Terocelo, said: "Communication devices, including cell phones, cordless phones, ham radios, citizens band radios, family radios, general mobile radios, multiple use radios, pagers, wireless (WiFi, cellular) computer adapters, wireless PDAs, network and multi-media appliance adapters, GPS trackers, and others, are typically limited to communications on a specific frequency band. The communications industry is looking for a way to create multi-mode wireless devices, based upon a system-on-a-chip that can handle multiple frequency bands, understand multiple transmission protocols, be reconfigured on the fly, and be easily upgraded. With the convergence of audio, video, data processing and communications services in wireless appliances, True Software Radio offers reconfigurable wireless platform architectures for both computing and communications devices. More importantly, we believe our patent filings and our continuing technology development programs establish the company as one of the preeminent leaders in the communications technology evolution, which is an ever expanding, multi billion dollar marketplace."

Ron Hickling, Chief Technology Officer of the company stated: "The development of wideband front end receivers and transmitters is key to achieving frequency agility and realizing the ultimate goal of software radio transceivers. This is a critical component of our direct conversion transmission core technology. We know of no other digital filter that can operate continuously across different frequency bands or that automatically adjusts to the proper frequency when transmitting wireless signals. This circuit does both."

This invention is part of Terocelo's True Software Radio, a wireless transmitter/receiver-on-a-chip technology that operates continuously across different frequency bands, controlled entirely by software. While this patent application is another in a series of patents covering the company's Lycon family of chips and its True Software Radio (TSR) technologies, it is applicable to a broad range of communications devices for both wired and wireless environments.
