Title: Miniature Frequency Standard Based nn All-Optical Excitation
and a Micromachined Containment Vessel.
Abstract: This invention is jointly owned by NIST and the
University of Colorado. A microwave frequency standard is provided
which allows for miniaturization down to length scales of order one
micron, comprising a modulated light field originating from a laser
that illuminates a collection of quantum absorbers contained in a
micro-machined cell. The frequency standard of the present invention
can be based on all-optical excitation techniques such as coherent
population trapping (CPT) and stimulated Raman scattering or on
conventional microwave-excited designs. In a CPT-based embodiment, a
photodetector detects a change in transmitted power through the cell
and that is used to stabilize an external oscillator to correspond to
the absorber's transition frequency by locking the laser modulation
frequency to the transition frequency. In a stimulated Raman scattering
(SRS) embodiment, a high-speed photodetector detects a laser field
transmitted through the cell beating with a second field originating in
the cell. Both the locked laser modulation frequency and the beat
frequency are very stable as they are referenced directly to the atomic
transition.

Title: Low Cost Portable Refreshable Tactile Graphic Display.
Abstract: Pressure-based refreshable scanning tactile graphic
display apparatus and methods are disclosed for localized sensory
stimulation. The apparatus include a display array having stimulus
points embedded in a matrix, an energy source applied at the stimulus
points through a modulator, a control unit, and a position sensing and
feedback unit or units (such as a mouse-type device or data glove, for
example). The energy source is preferably stored and pressurized fluid
with application to selected stimulus points (pins, for example)
preferably directed at a microvalve array under the control of a
computer-based control unit.

Title: Optical Probes for Chemical and Biochemical Detection in
Liquids.
Abstract: A class of optical sensors is provided for chemical and
biochemical detection in liquids in which the sensing element is a low-
loss optical resonator that requires or benefits from precision optical
contacting in the fabrication process. Novel resonator designs can be
created by contacting multiple components to form integral sensing
elements with low-loss mechanically strong bonds between components.
Stigmatic, weakly stigmatic and astigmatic Gaussian mode resonators and
whispering gallery mode resonators are described which can be immersed
in a liquid to detect chemical species through a change in optical
properties. High-reflectivity coated surfaces are used to permit direct
excitation of resonator modes by a propagating optical beam, while
total internal reflection surfaces provide an evanescent wave for
sampling the optical properties of the ambient medium. Resonators are
described with vicinal input and output ports, which
[[Page 16803]]
facilitate the construction of compact, distal probes where input and
output beams are introduced and accessed in close proximity.

Title: Spectrally Tunable Solid-state Light Source.
Abstract: A radiometrically stable, spectrally tunable, solid-state
source has been developed. The radiometric outputs of individually
controlled, narrow bandwidth, solid-state sources with different
spectral distributions are combined in an integrating sphere to
approximate any desired spectral distribution. Utilizing a sufficient
number of independent solid-state source channels, the source can be
tuned to approximate the spectral distribution of any desired source
distribution. A stable reference spectroradiometer that is integrated
into the solid-state light source measures the spectral radiance and is
used to adjust the output of the individual channels.

Title: Controlled Vesicle Self-Assembly in Continuous Two Phase
Flow Microfluidic Channels.
Abstract: It shows the formation of liposomes that encapsulate
reagents in a continuous 2-phase flow planar microfluidic network with
precision control of size, over the range of 100 nanometers to 300
nanomaters, by control of liquid flow rates. By creating a solvent-
aqueous interfacial region in a microfluidic format that is homogenous
and controllable on the length scale of a liposome, the fine control of
liposome size and polydisperisity is facilitated.
