Abstract: Stair climber apparatuses have a control circuit that controls the speed and torque of an electric motor and controls an output torque direction of the electric motor. The control circuit controls the speed of the electric motor and the output direction of the electric motor to maintain a constant speed of travel of a plurality of stairs in a downward direction along an inclined support when an operator is stepping on the plurality of stairs in an upward direction. When a change in output torque direction of the electric motor torque is required to maintain the constant speed of travel of the plurality of stairs in the downward direction along the inclined support, the control circuit controls the speed of the electric motor down to a zero speed. Methods are for operating the stair climber apparatuses.

Abstract: A multi-limb exercise machine and method that includes a plurality of user-movable input components, an input measurement device associated with each of the input components, a feedback device for providing the user with output information that indicates the difference between a current performance level and a performance target, and a processor that receives input information about user effort applied to each of the input components and communicates the output information to the feedback device. The input components are each configured to be moved by a limb of a user and to resist being moved. The processor determines the difference between performance levels based at least in part on a reward bias that decreases the difference more for effort applied to one of the input components than for effort applied to another of the input components.

Abstract: A power measurement assembly mounted within an axle. In a specific example, the axle is a spindle that is interconnects the cranks of a bicycle, exercise, bicycle, or other fitness equipment. The power measurement assembly may include strain gauges connected with an appropriate circuit (e.g., Wheatstone bridge) that provides an output of the force on the axle by a rider pedaling the crank. In the case of an axle, the strain gauges measure the torsion due to the applied torque on the crank.
