20100173101 | METHOD OF MANUFACTURING THICK-FILM, LOW MICROWAVE LOSS, SELF-BIASED BARIUM-HEXAFERRITE HAVING PERPENDICULAR MAGNETIC ANISOTROPY - A method of producing a relatively-thick film of a magnetic material on a substrate for use in microwave and millimeter wave devices is disclosed. The method includes preparing a wet paste comprising a binder material, glass frit, and a finely-grained magnetic material; applying the wet paste over a stencil, template or mask disposed on the substrate, to form a film on a surface of the substrate; drying the wet paste within an applied magnetic field, to vaporize fluid and organic compounds in the binder material and to produce a desired magnetic orientation in the magnetic film; and sintering the magnetic film. Hot pressing the magnetic film during sintering by adding weight on the film improves density. | 07-08-2010 |

20120154234 | ANTENNA MODULE HAVING REDUCED SIZE, HIGH GAIN, AND INCREASED POWER EFFICIENCY - A broadband integrated circulator antenna (BICA) module for receiving and transmitting signals with high efficiency and high gain. The BICA can have a bandwidth of over 70% of a radar band and can operate in frequencies from UHF to S-band and above. The BICA has a stack configuration that includes a low profile antenna, a reflecting layer or a metamaterial substrate layer, and a circulator. The circulator is placed proximal to antenna, which greatly reduces the size of the BICA. The circulator can be a stripline Y-junction ferrite circulator and the antenna can be a coaxial center fed bow-tie antenna. The reflecting layer or metamaterial substrate layer can comprise electronic bandgap metamaterial and a high permeability ferrite substrate. The high permeability ferrite substrate can be cobalt substituted Z-type barium hexaferrite. | 06-21-2012 |
20120293023 | Voltage Tuning of Microwave Magnetic Devices Using Magnetoelectric Transducers - Tunable microwave magnetic devices that provide increased performance with reduced size, weight, and cost. The disclosed microwave magnetic devices are voltage-tunable devices that include ferrite substrates. To tune the devices, the magnetic permeability of the respective ferrite substrates is varied by external, voltage-tuned, magnetic fringe fields created by one or more magnetoelectric (ME) transducers. | 11-22-2012 |
20150035522 | Device For Direct Microwave Measurement of Permeability as a Function of High DC Voltage - A sample holder and a coaxial method of measuring the permeability of magnetoelectric materials as a function of applied DC voltage are described. The sample holder reduces electromagnetic radiation losses as compared to conventional devices. The connections in the sample holder are electrically isolated from measuring equipment, preventing damage. A complementary algorithm to analyze the signal from the sample and calculate the permeability of the sample is described. | 02-05-2015 |

20110233117 | MULTI FILTER LUBRICANT PURIFICATION SYSTEM - A lubricant reclamation configuration includes a series of fluid inlets that distribute the fluid to a series of parallel arrangement of individual filter assemblies. A filter control valve assembly is assembled between the distribution manifold and each respective filter assembly individually controlling fluid flow between the distribution manifold and each respective filter assembly. The filter assembly processes the fluid. The processed fluid is collected and retuned to the system via a series of collection channels. The distribution manifold is preferably fabricated of a series of plates. | 09-29-2011 |

20080299202 | Controlled-Delivery System of Pharmacologically Active Substances, Preparation Process and Medical Use Thereof - The invention concerns a system for biocompatible drug release comprising: (i) a polymer matrix; (ii) an inorganic component located inside said matrix and characterized by a lamellar structure with a net positive or negative charge able to intercalate (iii) a pharmacologically active principle into said lamellar structure, by establishing an ionic type of bond with it and thereby obtaining an intercalation compound. The preparation process for the release system comprises the stages of: treating the lamellar solid in such a way as to give it a net positive or negative charge, then combining it with the chosen active principle, also in an ionic form, to obtain an intercalation compound which is then mixed with the polymer matrix. The release system can be employed in making medical devices, like sutures, membranes, osteosynthesis plaques, multilayered devices, gels and drug delivery systems. | 12-04-2008 |
