Patents by Inventor Joseph V. PAMPANIN

Joseph V. PAMPANIN has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11639955
    Abstract: The fault detection system described provides an efficient method to test and monitor component to component connectivity in an electronic package using on chip test circuits and on chip components, which reduces the need for external testing equipment and analysis. The on chip nature allows for both real time testing in the assembly process of the electronic packages and during use of the electronic package by determining an on chip reference measurement and using the reference measurement to determine an operational status of the package.
    Type: Grant
    Filed: August 23, 2021
    Date of Patent: May 2, 2023
    Assignee: Cisco Technology, Inc.

  • Publication number: 20220337194
    Abstract: Embodiments provide for a tunable driving circuit by monitoring a frequency of a ring oscillator of an electrical integrated circuit connected to an optical modulator to determine operational characteristics of the electrical integrated circuit; setting, based on the operational characteristics, a driving voltage for a plurality of tunable inverters and a plurality of fixed gain inverters that control the optical modulator, wherein each tunable inverter of the plurality of tunable inverters is connected in parallel with a corresponding fixed gain inverter of the plurality of fixed gain inverters on one of a first arm and a second arm connected to the optical modulator; and setting an amplification strength for the plurality of tunable inverters based on the operational characteristics.
