    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

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.
