Abstract
A first determination that a range of motion of a user of an exercise machine is between pre-determined motion thresholds is made. While the range of motion of the user is between the pre-determined motion thresholds, a velocity of the cable being below a pre-determined velocity threshold is determined. In response to determining that the velocity of the cable being below the pre-determined velocity threshold while the range of motion of the user is between the pre-determined motion thresholds, a second determination that the user should be spotted is made, Torque of a motor is reduced based at least in part on the second determination that the user should be spotted.
Claims21
(canceled)
An exercise machine, comprising:
- an actuator;
- a motor;
- a cable coupled between the actuator and the motor;
- and
- a processor configured to:
- monitor a range of motion associated with a user of the exercise machine, wherein the actuator is moving in a first direction during a first portion of the range of motion and a second direction during a second portion of the range of motion, wherein the first direction is opposite the second direction;
- cause the motor to rotate in a direction opposite the first direction using a first amount of torque during the first portion of the range of motion;
- and
- cause the motor to rotate in a direction opposite the second direction using a second amount of torque during the second portion of the range of motion, wherein a magnitude of the first amount of torque is different than a magnitude of the second amount of torque.
A method, comprising:
- monitoring a range of motion associated with a user of an exercise machine, wherein an actuator associated with the exercise machine is moving in a first direction during a first portion of the range of motion and a second direction during a second portion of the range of motion, wherein the first direction is opposite the second direction;
- causing a motor associated with the exercise machine to rotate in a direction opposite the first direction using a first amount of torque during the first portion of the range of motion, wherein the actuator is coupled to the motor via a cable;
- and
- causing the motor associated with the exercise machine to rotate in a direction opposite the second direction using a second amount of torque during the second portion of the range of motion, wherein a magnitude of the first amount of torque is different than a magnitude of the second amount of torque.
A computer program product embodied in a non-transitory computer readable medium and comprising computer instructions for:
- monitoring a range of motion associated with a user of an exercise machine, wherein an actuator associated with the exercise machine is moving in a first direction during a first portion of the range of motion and a second direction during a second portion of the range of motion, wherein the first direction is opposite the second direction;
- causing a motor associated with the exercise machine to rotate in a direction opposite the first direction using a first amount of torque during the first portion of the range of motion, wherein the actuator is coupled to the motor via a cable;
- and
- causing the motor associated with the exercise machine to rotate in a direction opposite the second direction using a second amount of torque during the second portion of the range of motion, wherein a magnitude of the first amount of torque is different than a magnitude of the second amount of torque.
