Closed loop control of resistance in a resistance-type exercise system
First Claim
1. An exercise system, comprising:
- a user input arrangement;
a rotatable member that rotates in response to an input force applied by a user on the user input arrangement;
a power sensing arrangement configured to sense power applied to the rotatable member due to the input force applied by the user; and
a variable resistance arrangement interconnected with the power sensing arrangement and with the user input arrangement, wherein the resistance arrangement is operable to resist rotation of the rotatable input member, and wherein the resistance arrangement is variable in response to the power sensing arrangement to vary the resistance to rotation of the rotatable member.

Abstract
An exercise system includes a user input arrangement; a rotatable member that rotates in response to an input force applied by a user on the user input arrangement; a power sensing arrangement that senses power applied to the rotatable member due to the input force applied by the user; and a variable resistance arrangement interconnected with the power sensing arrangement and with the user input arrangement. The resistance arrangement applies resistance to rotation of the rotatable member, and is variable in response to the power sensing arrangement to vary the resistance applied to the rotatable member. The variable resistance arrangement may be a brake that interacts with the rotatable member to resist rotation of the rotatable member, and to thereby resist the input force applied by the user. The variable resistance arrangement includes a controller for controlling the brake in response to the power sensing arrangement.
