3. THEORY OF OPERATION The Gauntlet is not motor driven The electrical supply to the unit is necessary only for reliable and consistent operation of the electronic console This feature also allows the electronics to be viewed when the machine is not being used as opposed to some other equipment which must be in use to provide an active and viewable display The body weight of the user provides kinetic energy used for speed control and resistance This is accomplished by a drive system which sums the oscillating motion of the steps into 8 continuous rotary motion This rotary mo tion is directed to a gearbox which in turn drives an alternator at sufficient RPM to provide a smooth reliable means of speed control Excess electrical energy created during this process is dissipated in an exter nal electrical resistor in the form of heat In summary the work being performed by the user kinetic energy is converted to electri cal energy which is then converted and dis sipated as heat The size of the electrical load is controlled on the field side of the al ternator This manages the energy at low current and limits the heat producing com ponents to the load resistor which is designed to dissipate heat well in excess of the Gauntlet s requirements MAINTENANCE 1 Removal Of Side Panels 1 Side panels are attached magnetically and are kept in proper alignment by two screws located at the top extreme ends of each side panel To re

This feature allows direct com parison when desired between individuals of similar demographics but with different weights when tested under identical speed conditions such as athletic teams military recruits etc 4 The Gauntlet never needs calibration since the resistance is body weight not fric tional devices which will wear out Speed is computer checked 100 s of times per second so calculations are constantly updated and always accurate 5 Due to the large muscle mass used when exercising on the Gauntlet it is possible for subjects to reach met levels impossible or impractical to achieve on other equipment R 6 There are no inertia or sh xk loads to stress joints ligaments or muscles as is the case with other popular forms off exercise 7 There are no weight limits on Gauntlet It has been operationally tested at weight loads exceeding 500 Ibs 8 No RF interference is generated by the mechanics of the Gauntlet beca vse there are no electrical motors stair case is powered by body weight and speed control led by an electromechanical bra king system COMPUTER BASICS The purpose of the computer console is to provide automation of the workout and a friendly method for obtaining necessary data and displaying workout results Before your initial exercise on the Gauntlet it is a good idea to become familiar with the com puter console and its operatiom There are three areas of the console whic
