    Abstract: One embodiment comprises an apparatus for applying energy to a hollow anatomical structure having an inner wall. The apparatus comprises an elongate shaft having a distal end and a proximal end opposite the distal end; and a capacitive treatment element located near the distal end. The capacitive treatment element is sized for insertion into the hollow anatomical structure and placement near the inner wall. The capacitive treatment element is configured to create an electric field that extends at least partially into the inner wall. Other devices and methods for treatment of hollow anatomical structures are disclosed as well.

    Abstract: A control system and method for interactive startup and shutdown of a steam turbine driven chiller unit is provided. The chiller unit includes an integrated central control panel to control operation of both the steam turbine system and the refrigerant system. The central control panel has startup control system to assist an operator manually start the steam turbine system and the refrigerant system and a shutdown control system to assist an operator manually shutdown the steam system and the refrigerant system. Both the startup control system and the shutdown control system include logic for performing necessary protective actions and for notifying an operator when to perform required actions.

    Abstract: An intercooled gas turbine is provided having an air cooled heat exchanger and a chiller disposed to remove heat from the cooling medium of the intercooler heat exchanger. During peak hours when the turbine is in operation, the air cooled heat exchanger is used primarily to cool the cooling medium of the intercooler heat exchanger. During off peak hours when the turbine is idle, the air cooled heat exchanger is used to remove heat from the condenser of a chiller system associated with a gas turbine inlet air cooling system. An additional liquid to liquid heat exchanger may be provided in-line between the intercooler heat exchanger and the air cooled heat exchanger to further cool the intercooler heat exchanger cooling medium using chilled water before the cooling medium passes back into the intercooler heat exchanger. The chilled water may be provided directly from the chillers, or from a thermal energy storage tank, or from the cooling coils of a turbine inlet air cooling system.
