| 20080288777 | A Peer-to-Peer Access Control Method Based on Ports - A port based peer access control method, comprises the steps of: 1) enabling the authentication control entity; 2) two authentication control entities authenticating each other; 3) setting the status of the controlled port. The method may further comprise the steps of enabling the authentication server entity, two authentication subsystems negotiating the key. By modifying the asymmetry of background technique, the invention has advantages of peer control, distinguishable authentication control entity, good scalability, good security, simple key negotiation process, relatively complete system, high flexibility, thus the invention can satisfy the requirements of central management as well as resolve the technical issues of the prior network access control method, including complex process, poor security, poor scalability, so it provides essential guarantee for secure network access. | 11-20-2008 |
| 20110055561 | ACCESS AUTHENTICATION METHOD SUITABLE FOR THE WIRE-LINE AND WIRELESS NETWORK - An access authentication method includes pre-establishing a security channel between the authentication server of the access point and the authentication server of the user terminal and performing the authentication process at user terminal and access point. The authentication process includes 1) the access point sending the authentication_activating message; 2) the user terminal sending the authentication server of user terminal request message; 3) the authentication server of the user terminal sending to the user terminal response message; and 4) completing the authentication. | 03-03-2011 |

The method includes administering a sustained release drug delivery system to a mammalian organism in need of such treatment at an area wherein release of an effective agent is desired and allowing the effective agent to pass through the device in a controlled. | 05-13-2010 |
| 20100234817 | OCULAR TROCAR ASSEMBLY - The invention provides a trocar assembly for delivering a payload into tissue, such as an eye, comprising a primary housing, a cannula, a payload, an actuator and a trocar. | 09-16-2010 |
| 20100278931 | POROUS SILICON DRUG-ELUTING PARTICLES - The invention provides a biodegradable drug-eluting particle useful for the delivery of diagnostic or therapeutic agents. In certain embodiments, the drug-eluting particle of the invention comprises a biodegradable porous silicon body, a reservoir formed within the porous silicon body having at least one opening to an exterior of the body, wherein the reservoir contains a therapeutic or diagnostic agent, and an agent-permeable seal disposed over the at least one opening. The invention further provides a method for treating a patient to obtain a desired local or systemic physiological or pharmacological effect comprising administering a sustained release drug delivery particle of the invention. The invention also provides methods of fabricating a drug-eluting particle for releasing therapeutic agents | 11-04-2010 |
| 20110129541 | SUSPENSION DELIVERY SYSTEM FOR THE SUSTAINED AND CONTROLLED LOCAL RELEASE OF PHARMACEUTICALS - The invention relates to a novel suspension delivery system for the sustained and controlled release of pharmaceuticals. Methods of preparation and use are also disclosed. | 06-02-2011 |

| 20090123546 | Polymer-based, sustained release drug delivery system - Disclosed is a sustained release system that includes a polymer and a pharmaceutically active agent dispersed in the polymer. The agent is in granular or particulate form, and has a rate of release from the system that is limited primarily by the rate at which the agent dissolves from the granules into the polymer matrix. Advantageously, the polymer is permeable to the agent and is non-release-rate-limiting with respect to the rate of release of the agent from the polymer. | 05-14-2009 |
| 20090163457 | Compositions and methods for delivering a biologically active agent - The invention relates to codrugs having improved properties, methods for preparing and administering them, and methods of formulating and administering the codrugs as pharmaceutical preparations. In certain embodiments, the codrugs can be locally administered to deliver the constituent biologically active compound in a sustained-release fashion, reducing systemic concentrations of the biologically active compound. | 06-25-2009 |
