Abstract: Aspects of this disclosure relate to a front end architecture for selectively adding an external carrier aggregation band. A switch element can connect a radio frequency signal path to an antenna path through a frequency domain multiplexer, such as a diplexer, in a first mode. The switch element can connect the radio frequency path to the antenna path and bypass the frequency domain multiplexer in a second mode. The frequency domain multiplexer can be external to a front end module that include the radio frequency signal path. In the first mode, a front end system can support carrier aggregation with a band associated with circuitry implemented external to the front end module.

Abstract: A system and method of the purification of drinking water, ethanol and alcohol beverages is based on the action of hydrodynamic cavitation processing of microbiological and chemical contaminants, micro particles and colloidal particles. The fluid flow moves at a high rate through a multi-stage cavitation device and filtration module to generate hydrodynamic cavitation features in the fluid flow. The cavitation features generate changes in the velocity, pressure, temperature, chemical composition and physical properties of the liquid. The cavitation features also prevent the deposition of contaminants upon and remove contaminants from the surface of the filter module, reduce the load on the filter elements and increase the life of the filter module.

Abstract: A process for increasing protein yield from biomass (beans, oilseeds, cereals, nuts, rice, soybeans, bran, etc.), as well as, for reducing the amount of chemical and biological reagents used in the process, involves application of multiple hydrodynamic cavitation treatments of a biomass suspension or other combination of biomass with solvents and reagents—in the preparation, extraction, and processing or the biomass and proteins. The biomass suspension is preferably subjected to at least three cavitation treatments in order to facilitate the crushing of biomass, splitting of fibers, and rupture of cell membranes, thereby increasing the mass transfer surface area and intensifying the extraction of protein and lipids. At the stage of washing and neutralization the protein solution may be subjected to a fourth cavitation treatment to obtain the purified protein.

Abstract: A system and method for the purification of beverage fluids, primarily alcohol beverages, based on the action of hydrodynamic cavitation processing of microbiological and chemical contaminants, micro particles and colloidal particles. The system is a batch system with a single vessel having an extraction tube and discharge tube extending into the same reservoir of fluid. Fluid is drawn through the extraction tube and forced through the discharge tube. The discharge tube contains cavitation elements dispersed along its length to generate hydrodynamic cavitation in the fluid as it is pumped through. The discharge fluid is mixed with the fluid already in the vessel and is re-drawn through the extraction tube in continuous batch processing.
