Abstract: A lap counter system for multiple runners automatically counts and times one or more runner(s) during a workout session exercise at either an indoor or outdoor running track suitable for use at a health club, school, business, government or other organization promoting physical activity to enhance the health of their members. The system includes standalone, computer controlled, end user friendly components that displays fitness statistics during the use of the running track for each runner without impeding the athletic activity with a cumbersome wearable device. The system preferably includes a display visible to the runner at one or more points around the track such as a scoreboard with the aforementioned statistics displayed providing the runner with a virtual coach.

Abstract: An assembly line for economically and efficiently assembling a core into a recuperator. The assembly line has an inlet end, an assembly station, a welding station, a control station and an outlet end. The inlet end has a plurality of the cores to be used for assembly thereat. The core is positioned within the assembly station and an assembly fixture locates a ducting structure in a preestablished relationship to the core. The control station using a plurality of sensors sends an input to a controller and the welding station performs a weld fixedly securing the ducting structure to the core.
