A crankshaft damper for attachment to one end of a crankshaft of an engine. The crankshaft damper includes an elastomeric member attached to a hub, and an inertia ring connected to the hub through the elastomeric member. Several different structures for cooling the elastomeric member are disclosed that dissipate heat away from the elastomeric member. Air flow is induced near the elastomeric member by providing air flow openings in the inertia ring or the elastomeric member.

Systems and methods for designing and controlling distributed generation resources are disclosed. Monolithic or distributed controllers control the power requests sent to each distributed generation resource to achieve optimal efficiency using rule-based and/or fuzzy logic-based control techniques. High-impedance fault (HIF) detection circuitry allows power export to the utility grid in normal operating circumstances, and when an islanding condition is detected, ceases that export within two seconds and prevents further export until the condition is cleared.
