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 by the U.S. Government,
as represented by the Department of Commerce, and are 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: Nancy Hale, National Institute of Standards and
Technology, Office of Technology Commercialization, Physics Building,
room B-256, 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.
SUPPLEMENTARY INFORMATION: The inventions available for licensing are:
NIST Docket No. 89-042
Title: Method and Apparatus for Laser Control
Description: The disclosure is directed to a method and apparatus
for precisely controlling the frequency of a laser, and for precise
control of distance. In a disclosed embodiment, a laser beam is split,
modulated to obtain a frequency differential, and coupled to an
interferometer which is designed to produce two processed beams having
intensities that vary at the same ac frequency, but at a phase
difference that is indicative of the laser frequency. The processed
beams are converted to ac electrical signals which are coupled to phase
control circuitry. The phase control circuitry determines and phase
between the electrical signals and produces a control signal for
controlling the laser frequency. Phase offset increments are introduced
in the phase detection process, these phase offset increments resulting
in controlled changes in the laser frequency. The laser frequency can
be computed and read out as a function of the phase offset increments.
In another embodiment, the control signal is used to accurately control
a distance.
NIST Docket No. 90-017
Title: Apparatus and Methods for Implementing Error Correction in Rail
Time for Machine Tools with Encoder-Type Position Feedback
Description: This invention describes several ways to improve
machine tool control error correction technology. It specifically
addresses fixed geometric or thermally induced errors in systems
employing encoder-type position feedback signals. The invention
provides realtime, portable error correction techniques that can be
used with any endoder-type position feedback devices, with minimal
software or hardware changes.
NIST Docket No. 91-023
Title: Photovoltaic Solar Water Heating System
Description: This NIST invention provides a system for heating
water using electrical power generated by a photovoltaic array. The
efficiency of the system is optimized by matching the power output
characteristics of the photovoltaic array to the heater load.
NIST Docket No. 93-019
Title: Laser Controlled Nanolithography
Description: New NIST technology shows promise for creating three-
dimensional nanostructures. Using light to ``steer'' chromium atoms,
the technique can make rows of atoms 65 nanometers (nm) wide with 213
nm spacing. The ultimate limit is expected to be structures with widths
as small as 5 to 10 nm.
NIST Docket No. 94-001
Title: An Improved Apparatus for Precisely Measuring Accelerating
Voltages Applied to X-Ray Sources
Description: This invention is an improvement of an earlier
invention, Method and Apparatus for Precisely Measuring Voltage Applied
to x-Ray Sources (U.S. Patent Application Serial No. 08/021,232). The
new invention allows the accurate measurement of the accelerating
voltage applied to an x-ray tube. Variation in accelerating voltage
affects the amount of radiation penetrating the radiated object and
thus the contrast of the resulting radiographic image. In certain
diagnostic applications, e.g. mammography and coronary angiography,
radiographic contrast is critical to making an accurate diagnosis. The
invention allows precise measurement of the accelerating voltage and
thus accurate calibration of x-ray equipment to ensure proper contrast
in the resulting images.
