Stepper with sensor system
First Claim
1. A stepper with a sensor system to monitor exercise performance and generate exercise information, comprising:
- a frame assembly which includes a base frame and a center beam mounted securely on said base frame;
two foot-pedal arms respectively on opposite sides of said center beam, each of said foot-pedal arms having an end mounted pivotally on said frame assembly for pivoting about an axis transverse to said center beam;
a photo-detecting unit mounted operatively on said frame assembly, said photo-detecting unit including a first photo emitter and a first photo receiver opposite to and aligned with said first photo emitter;
a slotted wheel mounted on said pivot axis of said end of one of said foot-pedal arms with a flange member extending toward said center beam and between said first photo emitter and said first photo receiver, said flange member having a plurality of angularly spaced-apart openings, said slotted wheel swinging with said one of said foot-pedal arms to permit said first photo receiver to receive light intermittently through said openings from said first photo emitter and produce electrical signals corresponding thereto; and
an instrument control unit connected electrically to said photo-detecting unit so as to process said signals from said photo-detecting unit and generate exercise information based on said signals.

Abstract
A stepper is incorporated with a sensor system and includes a frame assembly with a base frame and a center beam mounted securely on the base frame, and two foot-pedal arms located on two sides of the center beam. Each of the foot-pedal arms has an end mounted pivotally on the frame assembly. The sensor system is adapted to monitor exercise performance and generate exercise information and includes a photo-detecting unit mounted operatively on the frame assembly, a slotted wheel mounted axially on the end of a corresponding one of the foot-pedal arms, and an instrument control unit. The photo-detecting unit includes two photo emitters and two photo receivers. Each of the photo receivers is opposite to and aligned with a corresponding one of the photo emitters. The slotted wheel has a flange member extending toward the center beam and between the photo emitters and the photo receivers. The flange member has a plurality of angularly spaced-apart openings. The slotted wheel swings with the corresponding one of the foot-pedal arms to permit the photo receivers to receive light intermittently from the corresponding photo emitters. The instrument control unit is connected electrically to the photo-detecting unit so as to process signals therefrom and generate the exercise information based on the signals.
