ABSTRACT:
An energy absorber module usable with a variety of exercising machines and including an air displacement fan which is driven by a pair of pull cords through a one way clutch. The fan is contained within a housing secured to the frame of the module and the pull cords extend through guide holes in a face board also secured to that frame. The pull cords are wound upon drums which drive the fan when rotated in one direction, but which are freely rotatable in the reverse direction because of the clutch. A return cord is also wound upon each drum, but in the reverse direction to the pull cords, and is connected to a return spring for causing reverse rotation of the drums. A signal proportional to the rotational speed of the fan is processed through an electronic circuit to provide appropriate work information on a meter or recorder. The pull cords can be selectively engagable with other guide means according to the type of machine with which the module is to be used.
