Christopher Brickner 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).

  • Real time distributed embedded oscillator operating frequency monitoring
    Patent number: 8514996
    Abstract: A method for clock monitoring in a network is provided. The method comprises receiving a first network clock signal at a network device and comparing the first network clock signal to a local clock signal from a primary oscillator coupled to the network device.
    Type: Grant

    Date of Patent: August 20, 2013
    Assignee: Honeywell International Inc.
    Inventors: Julie Pollock, Brett D. Oliver, Christopher Brickner
  • Clock and reset synchronization of high-integrity lockstep self-checking pairs
    Patent number: 8156371
    Abstract: An apparatus comprises first and second modules configured to operate in a lockstep mode and a reset mode. Each of the first and second modules is configured to asynchronously enter the reset mode when a parent reset signal is asserted at the respective each module. Each of the first and second modules is configured to, in response to the asserted parent reset signal being negated at the respective each module, indicate to the respective other module that the respective each module is ready to exit the reset mode and exit the reset mode when the respective other module has also indicated that the respective other module is ready to exit the reset mode.

  • CLOCK AND RESET SYNCHRONIZATION OF HIGH-INTEGRITY LOCKSTEP SELF-CHECKING PAIRS
    Publication number: 20100318884
    Abstract: An apparatus comprises first and second modules configured to operate in a lockstep mode and a reset mode. Each of the first and second modules is configured to asynchronously enter the reset mode when a parent reset signal is asserted at that module. Each of the first and second modules is configured to, in response to the asserted parent reset signal being negated at that module, indicate to the other module that that module is ready to exit reset mode and exit the reset mode when the other module has also indicated that the other module is ready to exit reset mode.
