| Dressing | 20120164276 | 20120628 |
 Bound salads and other food products can enjoy decreased separation with the addition of a source of glucomannan, especially at from 0.1 wt % glucomannan and higher. Glucomannan absorbs substantial amounts of moisture released by the inclusions such as tuna fish, potatoes, vegetables etc, and as such, prevents “watering out” of the salad. Moreover, glucomannan is resistant to certain enzymes released by the inclusions such as carrots, cabbage, vegetables, fruits etc. Particularly important in this respect are amylases. By virtue of its resistance to amylase, glucomannan can thicken dressings in light products such as light mayonnaise, which often include starches subject to degradation by amylase, with little or minimal “watering out” in extended use.

| Replay debugging | 20070288902 | 20071213 |
| Transactional programming promises to substantially simplify the development and maintenance of correct, scalable, and efficient concurrent programs. Designs for supporting transactional programming using transactional memory implemented in hardware, software, and a mixture of the two have emerged recently. Unfortunately, conventional debugging programs are often inadequate when employed in relation to code that employs transactional memory and new or modified techniques are needed. We describe techniques whereby certain facilities of a transactional memory implementation can be leveraged to provide replay debugging. With replay debugging, the user can examine a partial or complete execution of an atomic block after it has happened—for example, right before the execution commits. Moreover, in some cases the user can modify the replayed execution, and decide to commit the new modified execution instead... |

| Methods for making integrated-circuit wiring from copper, silver, gold, and other metals | 20060292857 | 20061228 |
| Integrated circuits, the key components in thousands of electronic and computer products, include interconnected networks of electrical components. The components are typically wired, or interconnected, together with aluminum wires. In recent years, researchers have begun using copper instead of aluminum to form integrated-circuit wiring, because copper offers lower electrical resistance and better reliability at smaller dimensions. However, copper typically requires use of a diffusion barrier to prevent it from contaminating other parts of an integrated circuit. Unfortunately, typical diffusion barrier materials add appreciable resistance to the copper wiring, and thus negate some advantages of using copper. Moreover, conventional methods of forming the copper wiring are costly and time consuming. Accordingly, the inventors devised one or more exemplary methods for making integrated-circuit wiring from materials, such as... |

| Photonic crystal reflectors / filters and displacement sensing applications | 20060280403 | 20061214 |
| We introduce a mechanically tunable photonic crystal structure consisting of coupled photonic crystal slabs. Using both analytic theory, and first-principles finite-difference time-domain simulations, we demonstrate that the transmission and reflection coefficients for light normally incident upon such structures can be highly sensitive to nano-scale variations in the spacing between the slabs. Moreover, by specifically configuring the photonic crystal structures, the high sensitivity can be preserved in spite of significant fabrication-related disorders. We expect such a structure to play important roles in micro-mechanically tunable optical sensors and filters.

| Optimization of mode selection in a laser resonator | 20060280508 | 20061214 |
| The so-called single-longitudinal mode of operation of a tunable laser beam source requires active control of the band-pass filters mounted in the laser resonator. As a rule, this entails one, or a combination of several filter elements, as for example birefringent filters, as well as etalons. In either case, the band-pass filter needs to be so adjusted as to locate precisely one of the feasible longitudinal modes of the laser at the exact maximum transmission of the band-pass filter. The invention consists in regulating such filter setting by way of a program-controlled digital signal processor DSP in such a way that the DSP modulates the filter element with an adjustable frequency, and such regulation exploits the phase of the laser intensity fluctuations induced thereby to regulate... |

| Narrow-band absorptive bandstop filter with multiple signal paths | 20060273869 | 20061207 |
| An absorptive bandstop filter includes at least two frequency-dependent networks, one of which constitutes a bandpass filter, that form at least two forward signal paths between an input port and an output port and whose transmission magnitude and phase characteristics are selected to provide a relative stopband bandwidth that is substantially independent of the maximum attenuation within the stopband and/or in which the maximum attenuation within the stopband is substantially independent of the unloaded quality factor of the resonators. The constituent network characteristics can also be selected to provide low reflection in the stopband as well as in the passband. The absorptive bandstop filter can be electrically tunable and can substantially maintain its attenuation characteristics over a broad frequency tuning range.
