Patents by Inventor Michael N. Gray

Michael N. Gray 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).

  • Method and apparatus for modeling dataflow systems and realization to hardware
    Patent number: 7509647
    Abstract: In hardware, performing computations on a stream typically requires handshaking signals to provide flow control. Many different handshaking protocols are available, and they are typically implemented in an ad hoc manner suited to the current design. An approach according to the invention uses a subset of the possible flow-control protocols in an effort to achieve a maximum amount of flexibility and reusability, while requiring only a moderate level of overhead when compared to manually-designed systems.
    Type: Grant
    Filed: May 23, 2002
    Date of Patent: March 24, 2009
    Assignee: Annapolis Micro Systems, Inc.
    Inventors: Robert L. Donaldson, Rhett D. Hudson, Lawrence M. Marshall, Jr., Michael N. Gray, James J. Sullivan, James B. Peterson, Teresa G. Smith, Michael P. Klewin, Dennis M. Hawver

  • Method and apparatus for remote measurement of exhaust gas
    Patent number: 5831267
    Abstract: A method and apparatus for sensing a composition of an exhaust plume includes a light source that radiates an infrared light beam having a plurality of predetermined wavelengths. A first of the predetermined wavelengths is associated with carbon dioxide and a second of the predetermined wavelengths is associated with a second gas, such as a hydrocarbon or carbon monoxide. The apparatus also includes a detector unit that detects the beam passing through the plume. The apparatus computes a ratio of the second gas to carbon dioxide based upon the first and second detected wavelengths, and this ratio is then multiplied by a predetermined estimation of a concentration of carbon dioxide in the plume.

  • Paperless parcel tracking system
    Patent number: 5313051
    Abstract: A portable paperless parcel tracking system capable of reading bar codes on packages, capturing signatures and alphanumeric data related to the parcels when entered into a touch panel display, disabling manual or finger touch entry when a stylus is near the surface of the display, storing the parcel related data electronically and transmitting the data to a host at a convenient time.
