  • Patent number: 9407011
    Abstract: An electromagnetic bandgap structure comprising a progressive cascade of a plurality of patterns of cells. The cells of each pattern are dimensioned so that each pattern has a reflection phase response centered at a different, but closely-spaced, frequency compared with the reflection phase response of an adjacently positioned pattern, so that the combined reflection phase response of the plurality of patterns provides a continuous wideband operational range.

  • Patent number: 7692592
    Abstract: A patch array antenna is disclosed. The patch array antenna includes a ground plane with two patches. Each patch is supported from the ground plane only by metal posts. The patch array antenna further includes two-pin-feed probes, each pin-feed probe coupled to one patch, and a two-way high power divider attached to both pin-feed probes.

  • Patent number: 5364631
    Abstract: A method for making a pharmaceutical composition is described. The composition is comprised of an organic acid derivative of alpha tocopherol, and may additionally comprise other lipids. The composition may be in the form of liposomes, and as such are associated with or entrap a bioactive agent. Particularly suited for such systems are drugs stable at acidic pH, for example drugs having imidazole groups, such as pilocarpine. The composition requires a stabilizer to maintain the bilayer phase of the organic acid derivative of alpha tocopherol in a low pH environment. Such a stabilizer is for example a detergent. Upon in vivo administration of the system and concomitant increase of pH, viscosity of the preparation increases.

  • Patent number: 5283969
    Abstract: An identification band having a pocket portion and a strap portion extending from the pocket portion. The pocket portion encloses identification information pertaining to the wearer. The periphery of the pocket portion is configured to convey a creative artistic impression, that is, a configuration resembling at least a portion of any one of a living being (alive now or in the past), cartoon character, a man-made functional article (such a transportation vehicle and a building), a natural object (such as a cloud or star) and a decoration (such as holiday decorations and artwork). The pocket portion may be relatively planar or be formed so that the artistic impression is three-dimensional.

  • Patent number: 5169637
    Abstract: A new and substantially improved type of lipid vesicle, called stable plurilamellar vesicles (SPLVs), are described, as well as the process for making the same and X-ray diffraction methods for identifying the same. SPLVs are characterized by lipid bilayers enclosing aqueous compartments containing one or more entrapped solutes, the concentration of such solutes in each aqueous compartment being substantially equal to the emunization of solutes used to prepare the SPLVs. The bilayers of SPLVs are substantially non-compressed. SPLVs are stable during storage and can be used in vivo for the sustained release of compounds and in the treatment of disease.

  • Patent number: 5000958
    Abstract: The invention encompasses mixtures of antimicrobial agents coencapsulated in liposomes which when administered in vivo exert an enhanced therapeutic effect. The therapeutic effectiveness of the coencapsulated antimocrobial agents is greater than that of the same combination administered either in solution or as a mixture of liposome populations each containing one of the antimicrobial agents.

  • Patent number: 4610868
    Abstract: Lipid matrix carriers are described which provide for the sustained release of bioactive agents in vivo or in vitro. The properties of the lipid matrix carriers of the present invention include high entrapment efficiencies; release of entrapped compounds in their active form; biodegradability and avoidance of vascular occlusion in vivo; and avoidance of sequestration of the bioactive agent in the liver and spleen.

  • Patent number: 4588578
    Abstract: A process for the preparation in a monophasic solvent system of a new type of lipid vesicles, called monophasic lipid vesicles (MPVs). MPVs can be made to encapsulate one or more bioactive agents. MPVs are stable during storage and can be used in vivo in the treatment of disease.
