Abstract: This invention relates to a novel soy isoflavone product with high purities and strong biological activities and the method of producing the same from natural soybeans, soybean materials (i.e. tofu dregs, soy molasses) and other plant sources. The method includes three steps consisting of extraction with an organic solvent, hydrolysis using an acid and crystallization using an antisolvent. The procedure is very simple and thus can be easily adapted for large-scale manufacturing. Moreover, the procedure is able to produce a high yield of total isoflavones at a lower cost. HPLC analysis and E-Screen bioassay reveal that the obtained product not only contains a high content of isoflavone aglycones by weight of dry matter but also exhibits strong estrogenic activity toward human cells. Therefore, the product should be efficacious for relieving menopausal symptoms and other estrogen-deficient diseases and can be used in health care supplements or as additives for foods, beverages or cosmetics.

Abstract: Methods of treating a carbon foam precursor to facilitate subsequent foaming of the material at low pressures, which may be on the order of about 0.5 to 1.5 atmospheres, are disclosed. In one embodiment, the carbon foam precursor is subjected to partial devolatilization under controlled conditions with subsequent foaming being effected at low pressure. The carbon foam precursor may be one of various forms of coal including raw coal, coal extract mesophase pitch, synthetic mesophase pitch or petroleum based pitch. The performing treatment of the carbon foam precursor may remove a portion of the internal blowing agent and may alter the fluidity of the carbon foam precursor matrix. In another embodiment, the precursor after being converted into a powder is subjected to oxidation prior to foaming.

Abstract: A fiber optic switch based on the magneto-optic effect of magnetic materials is presented. Due to the optical fiber based construction of the switching device it is suitable for optical fiber networks The on-off function of the switch is useful for isolation and connection of node(s) from a fiber optical network without having to turn off a laser. The switch is based on the Faraday Effect exhibited by magneto-optic materials. The all-fiber magneto-optic switch has a beam splitter at the input that splits an incoming signal into orthogonal polarized paths. Each path has at least one magneto-optic Faraday rotator (MOFR) controlled by a field. When the field is present, the polarization of the optical beam changes, thereby turning the switch on or off depending on the initial polarization of the beam. A beam coupler couples the orthogonal polarized paths at the output of the all-fiber magneto-optic switch. The MOFR is a bismuth substituted iron garnet.

Abstract: A method of manufacturing a rotor to be used in a dual-rotor lobe pump system for pumping a material at a periodic rate is provided. The method includes selecting a desired periodic flow rate for the material, selecting a number of lobes for the rotor, and selecting either a thickness of the rotor or a spacing between the dual-rotors' axes of rotation in the lobe pump. The method also includes determining the profile for the rotor based on the desired periodic flow rate, so that when the rotor is operated within the dual-rotor lobe pump system, the material can be pumped at substantially the desired periodic flow rate. In another embodiment of the invention, a lobe pump rotor profile is formed by the method described above.

The invention comprises a first anchor attachable to a first side of a joint of the subject's body, a second anchor attachable to a second side of the joint; and an elastic member connecting the first anchor and the second anchor, such that articulation of the joint in a first direction causes deformation of the elastic member and storing of energy, and articulation of the joint in a second direction causes relaxation of the elastic member wherein the energy is released and assists the subject to perform a motion in said second direction. The invention may be used at a subject's waist, ankle, wrist, knee, hip, elbow, shoulder, and/or at least one joint of the back and/or neck.
Abstract: A digital DC-DC converter is implemented using first-order delta-sigma modulation, rather than A/D conversion. In the DC-DC converter, a PWM generator converts an input DC voltage to a preset level DC voltage according to an input PWM signal. A converter converts the DC voltage from the PWM generator to a preset level voltage. A delta-sigma modulator converts a feedback voltage Vfd corresponding to the output voltage Vout of the converter to a 1-bit digital voltage Vo according to a preset reference voltage Vref. A counter counts logic 1's in 1-bit digital voltage signals Vo from the delta-sigma modulator. A delay controller controls a high-level delay time according to the number of logic 1's counted by the counter and transfers a PWM signal having the controlled high-level delay time to the PWM generator.

Abstract: A method and system for augmenting a corpus with documents on concepts not sufficiently covered within the corpus is provided. The augmentation system generates a corpus concept graph from the documents of a corpus. A corpus concept graph represents concepts of the documents as nodes and related concepts as links between nodes. To generate a corpus concept graph, the augmentation system identifies the concepts that are related within each document of the corpus and adds nodes and links to the corpus concept graph for related concepts. The augmentation system analyzes the corpus concept graph to determine whether the relatedness of concepts of the documents of the corpus is sufficient. If the relatedness of a pair of concepts is not sufficient, then the augmentation system attempts to identify documents not already in the corpus that are related to the concepts that are not sufficiently related.

Abstract: The present invention is directed to a reversible electrochemical sensor for polyions. The sensor uses active extraction and ion stripping, which are controlled electrochemically. Spontaneous polyion extraction is suppressed by using membranes containing highly lipophilic electrolytes that possess no ion-exchange properties. Reversible extraction of polyions is induced by constant current pulse of fixed duration applied across the membrane. Subsequently, polyions are removed by applying a constant stripping potential. The sensors provide excellent stability and reversibility and allow for measurements of heparin concentration in whole blood samples via protamine titration.
Abstract: Stand-alone modules or blocks for use in creating low-power sensor-based monitor/control systems. Each module performs a pre-defined function, and when included in a monitor/control network operates as a node on the network and automatically communicates with one or more connected nodes using a uni-directional packet-based protocol. One class of such predefined nodes communicates Boolean values, for example, with input sensor nodes detecting the presence or absence of environmental phenomena (e.g., motion, light, sound, water, button presses, etc.), intermediate nodes transforming those Boolean values using combinational or sequential logic, and output nodes converting the resulting Boolean values to environmental phenomena (e.g., beeping, light, electric relay activation, etc.) or to data for further processing by a computer. Another class of nodes communicates integer or number values.
