Abstract: A method and a system for monitoring the fermentation of alcoholic beverages are proposed. The method comprises carrying out an alcoholic fermentation process of a must to be fermented inside a fermentation tank (1); acquiring, by a plurality of sensors (2-5) arranged within the fermentation tank (1), different data of the must, said acquired data comprising: level data, pressure, temperature, and pH; receiving, by a computing device (6), the acquired data and computing a density of the must by implementing the following equation using the acquired data: ? = P gh , where ? is the density; P is the pressure; g is the specific gravity; and h is the height of the must; and computing, by the computing device (6), the Degrees Brix of the must as a function of the computed density.

Abstract: An apparatus for a mmWave RF scanner system is described that enables multiple modes of operation. The disclosed RF scanner may be configured to perform a variety of independent tasks, including antenna measurement in far-field or near-field mode, active array characterization, radome measurements, and material characterization. To achieve all proposed measurements, a nine-axis RF scanner system is disclosed. For all modes, the system may use a two-port vector network analyzer (100 kHz to 9 GHz) connected to a plurality of frequency extenders that increases the operating range from 75 GHz to 110 GHz. The system may also include a graphical user interface for autonomous operation in each mode.

Abstract: A search query may be expanded using one or more dictionaries from different knowledge domains or user intent. A search query may be analyzed to find keywords for which an expanded definition may exist, and a user may be able to select an expanded definition of that keyword to better hone their intent. A query may be expanded using Boolean AND, OR, or NOT statements for an expanded definition of the highlighted keyword. Results may be presented that may include the expanded definition. In some cases, different dictionaries may be selected by the user to match their search intent. Dictionaries may be professionally curated or may be developed from a user's history of search or other work product.

Abstract: A writing assistant may compare the context and structure of a document being written with a preexisting knowledge graph. The comparison may highlight overlaps, differences, and other comparisons that may assist an author. A document graph may be extracted from the author's words and other context, so that a search of the knowledge graph has a deep, rich context for the search. A document graph may include hierarchies, topics, and relationships between different elements. The document graph may identify elements as nodes and relationships as edges of the graph. In some cases, the document graph may include additional contextual information, such as information about the author, external organizations associated with the document, other context about the document itself. The comparison of the document graph with other knowledge graphs may be presented alongside an editing window, such that the comparisons may assist the author during document creation and editing.

Abstract: A system may monitor the voice state of a person speaking and may give immediate, real time feedback, as well as track the speaker's voice state during a verbal interaction alone, with one or many individuals. A system may have a set of pre-built analyzers, which may be generated for different languages, regions or dialects, gender, subgroups or other factors, as well as use cases such as public speaking, sales, caregiving, teaching or counseling among others. The analyzers may operate on a local device, such as a cellular telephone, wearable device or local computer, and may analyze a person's spoken voice to identify and classify the person's voice state and provide feedback or coaching to the individual based on certain defined parameters.

Abstract: The ecosystem for methane conversion and emissions reduction disclosed herein presents a low-cost solution to the global methane accumulation problem. Ruminants generate gases as part of their digestive process, including methane, and the negative effects of methane in our atmosphere are well known. Many attempts are underway to use diet modifiers to lessen the amount of methane created and therefore minimize the effect. The presented invention takes a different approach. A methane converter is used in conjunction with a closed system to first transform the methane into the less damaging CO2 and then to use the CO2 for feeding algae growth. Methane at concentration levels in the enclosed habitat are maintained low to minimize the possibility of explosion, and the conversion from methane to CO2 is triggered by heating the low concentration methane with a heated surface or small flame.

Abstract: A dual-polarized patch antenna, an dual-polarized patch antenna array, and a method for forming the same are provided. The dual-polarized patch antenna comprises a radome, a horizontal feed and a vertical feed, a first cross-shaped patch, and a ground plane including a cross aperture. The dual-polarized patch antenna may include a cross patch and a cross aperture to increase the isolation in a cross-polarization between a horizontal polarized signal and a vertical polarized signal in a first principle plane and to decrease a mismatch in co-polarizations between the horizontal polarized signal and the vertical polarized signal in a second principle plane.

Abstract: Methods and products relating the preservation of cultured mammalian epithelial or mesenchymal cells are provided. The methods involve the pre-treatment of epithelial cells with a solution containing a cryoprotectant amount of monosaccharides and/or disaccharides. The treated cells then are frozen, dried or freeze-dried in a minimum volume of solution and stored for later use. The invention avoids the use of materials that must be washed away from the preserved tissue prior to application of the tissue to a wound bed. The invention also permits the storage of epithelial tissue in a dry state.

Abstract: A fixture for testing a circumferentially compliant bioprosthetic valve. The fixture comprises a silicone rubber simulated aorta which approximates the geometry of a healthy human aorta and a cradle for the aorta. The compliance characteristics of the aorta can be selected by varying the proportions of ingredients in the silicone rubber, so that simulated aortas of different compliance but identical geometries can be provided. The compliant valve is disposed inside the aorta and held in place by suturing or the like. In one embodiment, the aorta and valve are supported by means of a cylindrical cradle, with the inflow and outflow ends of the aorta being folded over cylindrical rims on the respective inflow and outflow ends of the cradle. End caps are then fitted in place over the folded-over ends of the aorta, the end caps having holes therein to allow flow through the aorta and valve.
