  • Publication number: 20030185892
    Abstract: The present invention relates to intraocular drug delivery for treating ocular diseases. Particularly, the invention relates to particles useful for the delivery of certain pharmacologically active agents to treat ocular diseases. The particles contain calcium phosphate core particles, particularly nanoparticles, as delivery agents and adjuvants. The invention also relates to methods of making such particles and to methods of treating ocular disease by delivery of a therapeutic drug to an ocular surface using the particles of this invention. The invention further relates to methods of regulating ocular pressure using certain formulations according to the present invention.

  • Patent number: 6538422
    Abstract: A voltage sensing apparatus includes an output for a voltage tap point that is useful in representing the voltage on a conductor that passes through the voltage sensing apparatus. The voltage sensing apparatus also performs the function of a separable insulated conductor, e.g. a conventional bushing or bushing insert as utilized in the electrical power distribution field. The voltage sensing apparatus includes a molded body having an embedded capacitance screen that provides the output. The body is molded about the capacitance screen. An arrangement is provided for locating the capacitance screen within the molded body. In a preferred embodiment, the capacitance screen is molded from a conductive plastic preferably formed with an open mesh or screen structure that permits the free flow of molding material.
