Abstract: A method for displaying archived exercise classes comprising displaying information about archived exercise classes that can be accessed by a first user via a computer network on a display screen at a first location, wherein the first user can select among a plurality of archived classes, outputting digital video and audio content comprising the selected archived class, detecting a performance parameter for the first user at a particular point in the selected class, displaying the performance parameter on the display screen, and displaying performance parameters from a second user at a second location on the display screen such that at least one of the performance parameters from the first user and at least one of the performance parameters from the second user at the same point in the class are presented for comparison.

Abstract: An illustrative embodiment of the invention eliminates the circumferential thermal stresses found in a feedwater inlet nozzle of a once-through-vapor generator that are caused by the presence of steam in the nozzle during a low flow load condition. Specifically, The cold inlet feedwater is directed upwardly to fill and overflow the nozzle conduit and prevent steam entrance and collection in the nozzle, and then, impinges on a shroud which re-directs the flow downward into fluid flow contact with the nozzle conduit and through the vapor generator.
