Abstract: The present invention relates to processes for making macromolecular networks, macromolecular networks made by such processes, and methods of using such macromolecular networks to make materials such as ceramics. The macromolecular network's formation rate is controlled by using two species of reactants each of which comprised one functionality. This results in decreased macromolecular network processing costs and superior products.

Abstract: An ultrasound imaging system includes a control with which a user can view one or more training materials regarding how to use the system or perform an examination. The training materials are associated with one or more of the operating parameters of the ultrasound system. Upon selecting a help me control, a search is performed for those training materials that are associated with one or more current operating parameters of the ultrasound system. In another aspect, training materials include a record of one or more operating parameters used or described in the content of the training materials. When viewing training material, a user can select a “show me” control on the ultrasound system, which causes the operating parameters used or described in the training material to be loaded into the circuitry of the ultrasound machine. The user can then operate the ultrasound imaging system with the same imaging parameters used or described in the training material being viewed.
