EXERCISE MONITORING SYSTEM
First Claim
Patent Images
1. An exercise-monitoring system for use with an exercise device including a selectorized weight stack, the exercise-monitoring system comprising:
- a static-stack light transmitter positioned to transmit a static-stack reference light to a static-stack reflector throughout a range of motion of the static-stack reflector;
a static-stack light receiver positioned to receive from the static-stack reflector an amount of reflected static-stack reference light that is proportional to a distance between the static-stack reflector and the static-stack light receiver; and
a weight-determination module to output a weight indicator based on the amount of reflected static-stack reference light received by the static-stack light receiver.

Abstract
An exercise monitoring system for use with an exercise device including a selectorized weight stack includes a static-stack light transmitter for transmitting a reference light to a static-stack reflector and a static-stack receiver positioned to receive reflected reference light from the static-stack reflector. The exercise monitoring system further includes a weight-determination module that outputs a weight indicator based on an amount of reflected static-stack reference light.

11. An exercise system comprising:
-
a selectorized weight stack including a plurality of weights that are selectively separated into a static-stack and an active-stack that is lifted from the static-stack when a user performs an exercise; one or more compression springs supporting the selectorized weight stack; a static-stack light reflector located on the static-stack; a static-stack light transmitter positioned to transmit a static-stack reference light to the static-stack reflector throughout a range of motion of the static-stack reflector; a static-stack light receiver positioned to receive from the static-stack reflector an amount of reflected static-stack reference light that is proportional to a distance between the static-stack reflector and the static-stack light receiver; an active-stack light reflector located on the active-stack; an active-stack light transmitter positioned to transmit an active-stack reference light to the active-stack reflector throughout a range of motion of the active-stack reflector; an active-stack light receiver positioned to receive an amount of the active-stack reference light from the active-stack reflector that is proportional to a distance between the active-stack reflector and the active-stack light receiver; a weight-determination module to output a weight indicator based on the amount of reflected static-stack reference light received by the static-stack light receiver; and a repetition counting module to output a repetition indicator based on the active-stack reference light received by the active-stack light receiver. - View Dependent Claims (12, 13, 14, 15)

16. A method of monitoring an exercise, the method comprising:
-
transmitting a static-stack reference light along an optical path having a length that is proportional to an amount of static weight in a selectorized weight stack; receiving the static-stack reference light; and outputting a weight indicator based on an amount of received static-stack reference light. - View Dependent Claims (17, 18)
