Government Owned Inventions Available for Licensing

AGENCY: National Institute of Standards and Technology, Commerce.

ACTION: Notice of Government owned inventions available for licensing.

-----------------------------------------------------------------------

SUMMARY: The inventions listed below are owned in whole or in part by 
the U.S. Government, as represented by the Department of Commerce. The 
Department of Commerce's ownership interest in the inventions is 
available for licensing in accordance with 35 U.S.C. 207 and 37 CFR 
part 404 to achieve expeditious commercialization of results of 
Federally funded research and development.

FOR FURTHER INFORMATION CONTACT: Technical and licensing information on 
these inventions may be obtained by writing to: National Institute of 
Standards and Technology, Industrial Partnerships Program, Building 
820, Room 213, Gaithersburg, MD 20899; Fax 301-869-2751. Any request 
for information should include the NIST Docket No. and Title for the 
relevant invention as indicated below.

SUPPLEMENTAL INFORMATION: NIST may enter into a Cooperative Research 
and Development Agreement (``CRADA'') with the licensee to perform 
further research on the invention for purposes of commercialization. 
The inventions available for licensing are:

    NIST Docket Number: 96-050US.
    Title: Implementation of Role-Based Access Control in Multi-Level 
Secure Systems.
    Abstract: Role-based access control (RBAC) is implemented on a 
multi-level secure (MLS) system by establishing a relationship between 
privileges within the RBAC system and paris of levels and compartments 
within the MLS system. The advantages provided by RBAC, that is, 
reducing the overall number of connections that must be maintained, 
and, for example, greatly simplifying the process required in response 
to a change of job status of individuals within an organization, are 
then realized without loss of the security provided by MLS. A trusted 
interface function has been developed to ensure that the RBAC rules 
permitting individuals access to objects are followed rigorously, and 
provides a proper mapping of the roles to corresponding pairs of levels 
and compartments.

    NIST Docket Number: 96-052US.
    Title: Process for the Enactment of Workflow Using Role-Based 
Access Control.
    Abstract: A workflow sequence specified by a process definition is 
managed by a workflow management system which enacts each segment in 
the order specified by that process definition. Role-based access 
control (RBAC) is used to define membership of individuals in groups, 
i.e., to assign individuals to roles, and to then activate the roles 
with respect to the process at appropriate points in the sequence. Any 
individual belonging to the active role can perform the next step in 
the business process. Changes in the duties and responsibilities of 
individuals as they change job assignments are greatly simplified, as 
their role memberships are simply reassigned; the workflow process is 
unaffected.

    NIST Docket Number: 97-017US.
    Title: Domain Engineered Ferroelectric Optical Radiation Detector.
    Abstract: The invention uses electric field poling at room 
temperature to selectively reverse the direction of the spontaneous 
polarization in a z-cut LiNb03 electret to produce a bicell 
pyroelectric detector. Microphonic noise that is typical of monocell 
pyroelectric detectors is reduced in the present device. Investigation 
of the pyroelectric electret geometry and the vibration modes of the 
detector assembly may lead to designs with even greater microphonic 
suppression. More complicated domain reversal patterns may accommodate 
refined detector designs and could be used to create multi-element 
sensors.

    NIST Docket Number: 97-021US.
    Title: Temperature Calibration Wafer for Rapid Thermal Processing 
Using Thin-Film Thermocouples.

[[Page 10594]]

    Abstract: This invention enables the measurement of temperature and 
the calibration of temperature measurements in rapid thermal processing 
tools for silicon wafer processing to a greater accuracy than 
previously possible. The invention is a device which is a calibration 
wafer of novel construction and capabilities. The calibration wafer is 
comprised of an array of junctions of thin film thermocouples which 
traverse the silicon wafer (typically 200 mm in diameter) and are 
welded to thermocouple wires of the same composition as the thin films. 
The advantages of very low mass thin-film thermocouples in making these 
measurements are greatest under the extremely high heat flux conditions 
present in rapid thermal processing tools (100 w/cm\2\). In order to 
achieve these measurements with thin-film thermocouples at temperatures 
ranging up to 900 degrees celcius a novel approach was taken in the 
design and fabrication of the wafer including the incorporation of an 
adhesion film for the thermoelements, diffusion barriers, and high 
temperature dielectric insulators.
