Jerry's Patents

GRANTED PATENTS

So far, Jerry has been granted two patents, both of which were achieved during Jerry's employment with Motorola, UDS.

Data Timing Recovery Apparatus And Method

Jerome J. Viviano; PTO #: 5,228,064, Granted: July 13, 1993

A Motorola wireless product development team came to Jerry as part of the Motorola Research Staff, asking for him to come up with a simple, inexpensive timing recovery circuit to be used in their handheld transceiver. Jerry conceived of a unique idea, and proved it out through simulation of the transceiver. The invention only required about $0.75 worth of parts and a small subroutine to be coded in the board control processor. He relayed the concept back to the development team, which then implemented it into the final design of the product. The above patent describes Jerry's idea in detail.

Apparatus For Adjusting Signal Points, Equalizer Coefficients And The Like

Jerome J. Viviano, Teri C. Raynor; PTO #: 5,309,481, Granted: May 3, 1994

The second patent covers one of Jerry's most prized accomplishments. Motorola was competing against several other companies to win a contract with United Parcel Service. UPS needed a means of communicating package delivery data wirelessly from each of their 60,000 US delivery vehicles to their network hubs. Motorola was proposing the use of analog modems over the cellular system for this, but ran into a problem of significant signal distortion by the cellular system, which was not designed to handle modems. Motorola asked Jerry to come up with a solution. Jerry's invention, covered by the above patent, successfully implemented a machine learning process which allowed the modem to adapt to the severely distorted receive signal. The end result was the win of the UPS contract. The process is briefly covered in the Project X PowerPoint presentation on this page. You may view it online, or download it onto your machine.
