Matrix transformer and winding structure

A matrix transformer particularly suited to large voltage step-down, high current applications achieves increased good current sharing uniformity or air gap and electrical characteristics and reduced or eliminating termination losses, core losses and winding losses with a unitary magnetic core structure featuring sheets of magnetic material and a two-dimensional array of pillars on which windings, oriented in opposite directions on pillars that are adjacent in orthogonal directions, can be formed or placed comprising metallization on or embedded in a printed circuit board (pcb) structure. Magnetic flux density is reduced by at least one-half by dividing the magnetic flux in each pillar into two paths of increased width in the sheets of magnetic material. ...

Immunotherapeutic methods using irreversible electroporation

Methods for treating tissue with irreversible electroporation and immunotherapy are described. The methods include placing a probe in tissue within a human body, wherein the probe has at least a first electrode, applying a plurality of electrical pulses through the first electrode and a second electrode, causing irreversible electroporation (ire) of the tissue within a target ablation zone, and administering one or more exogenous agents into the tissue within the target ablation zone or to the human, thereby stimulating or otherwise modulating an immune system response within the body.. ... Virginia Tech Intellectual Properties Inc

Irreversible electroporation using tissue vasculature to treat aberrant cell masses or create tissue scaffolds

The present invention relates to the field of medical treatment of diseases and disorders, as well as the field of biomedical engineering. Embodiments of the invention relate to the delivery of irreversible electroporation (ire) through the vasculature of organs to treat tumors embedded deep within the tissue or organ, or to decellularize organs to produce a scaffold from existing animal tissue with the existing vasculature intact. ...

Cooler with emi-limiting inductor

A power device package includes a dielectric substrate having an upper conductor layer and a lower conductor layer, a semiconductor die coupled to the upper conductor layer of the dielectric substrate via conductive adhesive, a cooler including a protruding hillock having a top surface and outer sides, the lower conductor layer of the dielectric substrate being coupled to the surface of the protruding hillock via an adhesive, and a magnetic material attached mateably around the protruding hillock. The magnetic material includes inner sides abutting the outer sides of the protruding hillock.. ... Virginia Tech Intellectual Properties Inc

Method for jointly adapting an ofdm waveform and the demodulator for interference mitigation and harsh channels

The present invention provides a method and system for a processing multicarrier signal to create a spectral correlation across multiple antennas. The system includes at least one transmitter adapted to create a plurality of symbols, each symbol representing one or more bits from a plurality of bitstreams. ... Virginia Tech Intellectual Properties Inc

Variable dc link converter and transformer for wide output voltage range applications

A variable direct current (dc) link power converter is described. In one example, the power converter includes a first converter stage configured to convert power from a power source to power at an intermediate link voltage and a second converter stage configured to convert the power at the intermediate link voltage to power for charging a battery. ... Virginia Tech Intellectual Properties Inc

Interface converter common mode voltage control

Aspects of interface converter common mode (cm) voltage control are described. In one embodiment, a bi-directional alternating current (ac) to direct current (dc) interface converter system includes an ac-dc converter between an ac power system and an interface link and a dc-dc converter between a dc power system and the interface link. ... Virginia Tech Intellectual Properties Inc

Polymeric materials and articles manufactured there from

A method for manufacturing a three dimensional object includes steps of: providing a digital description of the object as a set of voxels; sequentially creating an actual set of voxels corresponding to the digital set of voxels. At least one voxel comprises a polymer derived from: polyol and an ionic monomer. ... Virginia Tech Intellectual Properties Inc

Cleaning and dewatering fine coal

Fine coal is cleaned of its mineral matter impurities and dewatered by mixing the aqueous slurry containing both with a hydrophobic liquid, subjecting the mixture to a phase separation. The resulting hydrophobic liquid phase contains coal particles free of surface moisture and droplets of water stabilized by coal particles, while the aqueous phase contains the mineral matter. ... Virginia Tech Intellectual Properties Inc

Apparatus for dewatering and demineralization of fine particles

Hydrophobic particles such as coal and hydrophobized mineral fines can be readily separated from hydrophilic impurities by forming agglomerates in water using a hydrophobic liquids such as oil. The agglomerates of hydrophobic particles usually entrap large amounts of water, causing the moisture of the recovered hydrophobic particles to be excessively high. ... Virginia Tech Intellectual Properties Inc

Parallel devices having balanced switching current and power

A power circuit includes a power source for providing electrical power and two driving transistors being disposed in parallel and receiving electrical power from the power source. Each of the two driving transistors includes a gate terminal, a source connection, and a kelvin source connection. ... Virginia Tech Intellectual Properties Inc
