Abstract:
A low dispersion comb filter or interleaver comprises a first birefringent element assembly having at least one birefringent element and a second birefringent element assembly having at least one other birefringent element. The first birefringent element assembly and the second birefringent element assembly are configured so as to cooperate with one another in a manner which mitigates dispersion of the interleaver. By aligning the polarization directions of the odd channels and the even channels so as to be parallel with respect to one another prior to entering the second birefringent element assembly, zero or nearly zero dispersion is obtained simultaneously for both the odd and even channels.
Abstract:
According to various disclosed embodiments, a conductor is patterned in a dielectric. The conductor can be patterned, for example, in the shape of a square spiral. The conductor can comprise, for example, copper, aluminum, or copper-aluminum alloy. The dielectric can be, for example, silicon oxide or a low-k dielectric. A spin-on matrix containing high permeability particles is then deposited adjacent to the patterned conductor. The high permeability particles comprise material having a permeability substantially higher than the permeability of the dielectric. The high permeability particles can comprise, for example, nickel, iron, nickel-iron alloy, or magnetic oxide. As a result, an inductor having a high inductance value is achieved without lowering the quality factor of the inductor.
Abstract:
A method is provided for forming an improved interconnect structure on a semiconductor body. A first metal layer is deposited on the semiconductor body. A sacrificial layer having a height is deposited on the first metal layer. The sacrificial layer and the metal layer are patterned to form separate metal lines with the sacrificial layer remaining on said metal lines. A low-k material is then deposited to fill the gaps between metal lines and to cover the sacrificial layer. The low-k material is then removed to a level within the height of the sacrificial layer. The sacrificial layer is then removed. A protective layer is deposited on top of the metal lines and the low-k material. A dielectric layer is deposited over the protective layer. The protective layer protects the low-k material from attack by chemicals utilized by subsequent process steps to etch vias in the dielectric layer, to strip photo-resist, and to clean the vias. The protective layer is then selectively etched away to make contact between a via plug and the metal lines.

Systems and methods for a call over network (CON) with a visualized summary are provided. In some embodiments, after the call concludes, a visualized summary of the call can be generated. The summary includes any of the recording of the call, transcriptions, scenario information, speaker information and the duration each speaker was talking, etc. Scenario may be generated by comparing the call speaking pattern to known templates of call types. Additionally, participant features employed in the call may be summarized in chronological relation to the calls progression in a visual format.
Abstract:
Systems and methods for improving quality of a call over network (CON) are provided. Call quality may be improved via pathway testing to determine data path quality. This may be utilized to inform buffering lengths, and also may be utilized to choose the data pathway utilized for transmitting the data. Pathway testing may employ collecting microphone data on one device, transmitting it across the various pathways, and then comparing the quality at the endpoint compared to the initial data.
Abstract:
Stabilized whole grain flours having a fine particle size and which exhibit good baking functionality are produced with high throughput using two bran and germ fractions and an endosperm fraction. One bran and germ fraction is a coarse fraction which is subjected to two stage grinding, but the second bran and germ fraction is a low ash, fine bran and germ fraction which is sufficiently fine so that it does not need to be subjected to grinding thereby reducing starch damage and increasing production with reduced grinding equipment load. Portions of the coarse bran and germ fraction which are ground in the first grinding stage to a sufficient fineness are separated out and not subjected to additional grinding further reducing starch damage and increasing production. The bran and germ fractions may be combined, subjected to stabilization, and combined with the endosperm fraction to obtain a stabilized whole grain flour.

The chimeric proteins are derived from fragments of influenza membrane proteins fused to heterologous proteins. The invention includes antigenic formulations and vaccines comprising VLPs of the invention as well as methods of making and administering VLPs to vertebrates, including methods of inducing immunity to infections, such as influenza.
Abstract:
A stabilized flour, such as stabilized whole grain wheat flour, exhibiting unexpectedly superior extended shelf life and superior biscuit baking functionality, may be produced with or without heating to inhibit lipase by subjecting whole grains or a bran and germ fraction or component to treatment with a lipase inhibitor, such as an acid or green tea extract. Treatment with the lipase inhibitor may be performed during tempering of the whole grains or berries or during hydration of the bran and germ fraction or component.

Abstract:
A light emitting diode (LED) system implements a power management technique. The LED system includes a plurality of LED drivers connected in series, each LED driver configured to regulate the current flowing through a corresponding subset of a plurality of LED strings. Each LED driver determines the tail voltages of the one or more LED strings of the corresponding subset. Each LED driver, except for the first LED driver in the series, also receives a voltage representative of the minimum tail voltage of the other subsets regulated by the upstream LED drivers. Each LED driver then provides the lowest of the voltage received from the upstream LED driver and the one or more tail voltages of the corresponding subset to the downstream LED driver. In this manner a voltage representative of the minimum tail voltage of the plurality of LED strings is cascaded through the series. A feedback controller monitors the minimum tail voltage represented by this cascaded voltage and accordingly adjusts an output voltage provided to the head ends of the plurality of LED strings.
