Russell Brian Schott is an inventor associated with Irvine, California, and Conexant Systems, Inc. His patent work addresses how a modem can determine whether a shared telephone line is already in use before going off-hook. Schott is credited with 1 patent.

Latest Patents

Schott’s patent, “Line in Use Detection,” describes an apparatus and method for ascertaining the state of a telephone line. A modem’s data pump checks the energy level of a capacitor coupled to the line before the modem goes off-hook. If the energy level exceeds a threshold, the line is considered in use, and the modem remains on-hook. If the level is at or below the threshold, the modem may go off-hook.

The patent also describes establishing energy profiles for other communication devices as they transition between on-hook and off-hook states. The modem can use these profiles to identify activity on the line or determine the state of a connected device. This approach aims to detect line use without adding hardware and to help prevent the modem from interfering with other devices sharing the telephone line.

Career Highlights

Schott’s listed company affiliation is Conexant Systems, Inc. The patent reflects work on practical modem technology, particularly the detection of telephone-line activity through energy measurements and signal behavior.

Collaborations

Raphael Rahamim and Robert W. Frankland are identified as Schott’s coworkers. The available information does not specify their roles in the patent or the extent of their collaboration with him.

Conclusion

Russell Brian Schott’s patent presents a hardware-conscious method for detecting whether a shared telephone line is in use, helping a modem avoid disrupting other connected communication devices.
