Abstract

An exercise machine is disclosed. The exercise machine comprises a motor, an actuator, an arm, and a cable. The cable is coupled between the motor and the actuator through the arm. The motor is configured to provide a nominal tension of resistance when an end of the cable is within a range of length from a zero point associated with the cable.

First claim

What is claimed is:

1 . An exercise machine, comprising:
a motor; an actuator; an arm; a rail including a plurality of track holes and a plurality of sensors, wherein the plurality of sensors includes a first sensor and a second sensor, wherein the plurality of track holes includes a first track hole and a second track hole, wherein the first track hole and the second track hole are at different locations, wherein the first sensor is in the first track hole, and wherein the second sensor is in the second track hole; and a cable coupled between the motor and the actuator through the arm, wherein the motor is configured to provide an initial tension of resistance when an end of the cable is within a range of length from a zero point associated with the cable, wherein the motor is configured to: determine that the end of the cable is outside the range of length from the zero point associated with the cable based on a change in the length of the cable since the end of the cable was last within the range of the length from the zero point, wherein the change in the length is determined based on the plurality of sensors determining that a pin has moved from one track hole to another track hole, wherein a location of the pin corresponds with the length of the cable; and in response to a determination that the end of the cable is outside the range of length from the zero point associated with the cable, provide a specified tension of resistance, wherein the specified tension of resistance is greater than the initial tension of resistance.

2 . The exercise machine of claim 1 , wherein the zero point associated with the cable is determined during a power-up of the exercise machine.

3 . The exercise machine of claim 2 , wherein the zero point associated with the cable is determined by retracting the cable until the cable reaches a stopping position.

4 . The exercise machine of claim 1 , wherein the arm is configured to be positioned at a plurality of different locations along the rail.

5 . The exercise machine of claim 4 , wherein the zero point associated with the cable is different at each location of the plurality of different locations.

6 . The exercise machine of claim 1 , wherein the zero point associated with the cable corresponds to a position of the cable when the actuator is fully retracted.

7 . The exercise machine of claim 1 , wherein the zero point associated with the cable is recalibrated after detecting a lack of cable motion for a predetermined amount of time.

8 . The exercise machine of claim 1 , wherein the zero point associated with the cable is determined when the pin is inserted into the corresponding track hole associated with one location of the different locations.

9 . The exercise machine of claim 1 , wherein the specified tension of resistance is specified by a user of the exercise machine.

10 . The exercise machine of claim 1 , wherein the specified tension of resistance is specified by a processor of the exercise machine.

11 . The exercise machine of claim 1 , wherein the motor is a pancake motor.

12 . The exercise machine of claim 1 , wherein the exercise machine is capable of being wall mounted.

13 . The exercise machine of claim 1 , wherein the actuator is a handle.

14 . The exercise machine of claim 1 , wherein the actuator is a bar.

15 . The exercise machine of claim 1 , wherein the actuator is a strap.

16 . The exercise machine of claim 1 , wherein the arm is capable of being horizontally or vertically pivoted.
