  • Patent number: 9381217
    Abstract: Methods of encapsulating cargo in a microgel droplet, microgel droplets prepared according the provided methods, and methods of use thereof are disclosed. The methods of preparing cargo-encapsulated microgels generally include flowing through a flow-focusing nozzle of a microfluidic device a macromer phase, an oil phase, and a crosslinker phase to form microgel droplets by oil-water emulsion. The phases are pumped, injected, or flowed through the microfluidic device such that as the macromer phase approaches the flow focusing nozzle, the co-flowing oil phase shields the macromer from contact with the crosslinker phase until flow instability occurs and macromer phase droplets form. After flow instability occurs, the crosslinker diffuses from the crosslinker phase into the droplets in an effective amount to covalently crosslink the macromer into a microgel network encapsulating the cargo in the crosslinked macromer.

  • Patent number: 8589949
    Abstract: An invention is disclosed for improved computer system management by allowing complex computer-monitored events to be handled in different formats for correlation, analysis and action. Specifically, a method and system are disclosed for processing multiple heterogeneous event types in a complex event processing (CEP) engine.

  • Patent number: 6502137
    Abstract: Upon the receipt by an HTTP server over the Internet from a web browser for title information for audio or video data, the HTTP server retrieves the title information and sends it to the web browser along with a passcode particularly associated with the requested title information. Then, when an application server coupled to the HTTP server receives a request for the audio or video data from a viewer application associated with a web browser, the audio or video data will only be sent from a video server to the viewer application over the Internet if the request for the audio or video data is accompanied by the passcode. After sending the audio or video data to the viewer application, the passcode is invalidated. If the request for the audio or video data requests titles other than those associated with the passcode, the request is denied.
