  • Patent number: 7775231
    Abstract: The present invention relates to methods and devices for retrofitting fire hydrants with additional structure for reducing the potential that those with ill intent can foul municipal water supplies by introducing toxins or other materials into fire hydrants. Various embodiments include a replacement hydrant body having an enlarged diameter portion that can be installed to replace an existing hydrant body. The replacement hydrant body can include a secondary valve comprising a seat, biasing structure, and a restriction member to close off portions of the hydrant otherwise available for receipt of toxic or other materials when the fire hydrant nozzle cap is unscrewed and open.

  • Patent number: 7765525
    Abstract: An Operations Manager subsystem decouples the generation of operational events from an associated behavior triggered by those events. The Operations Manager subsystem allows changing the associated behavior without requiring rebuilds or recompilations of the source code. In addition, changes to policies are possible even at runtime in order to enable more agile debugging and better application supportability. The Operations Manger subsystem includes separate reporting and subscription services. The reporting services provide an API defining operational code for the generation of operational events. The subscription services include a file system and an API that support multiple user subscriptions to the various code operational events defining the behavior associated with those events.

  • Publication number: 20090216205
    Abstract: A system and method for continuously aspirating and collecting fluid waste during a medical procedure without interruption for disposal of the collected fluid waste. The system includes a first reservoir in communication with a vacuum source which produces a negative pressure therein to draw the fluid waste from the patient using a suction hose connected thereto. A second reservoir is in communication with the first reservoir. A pump draws fluid from the first and second reservoirs while additional fluid waste continues to be drawn into the first reservoir through the fluid inlet.
