Abstract

An exercise tracker includes a force sensor programmed to output a force signal representing a force applied to a cable associated with a piece of exercise equipment. The exercise tracker further includes a processing device programmed to receive the force signal and determine, from the force signal, exercise data including an amount of weight lifted.

Claims

1. An exercise tracker comprising:

a base;

a plurality of protrusions, extending from the base, for contacting a cable associated with a piece of exercise equipment having a variable weight stack and a pulley for receiving the cable, wherein the plurality of protrusions are configured to attach the base to the cable between the pulley and the variable weight stack, wherein a location of one of the plurality of protrusions is adjustable via a positioning screw, and wherein the base moves in accordance with movement of the cable;

a force sensor programmed to output a force signal representing a force applied to the cable; and

a processor programmed to receive the force signal and determine, from the force signal, exercise data including an amount of weight lifted.

2. The exercise tracker of claim 1, wherein the force sensor includes a tension meter disposed on the cable, and wherein the force sensor is programmed to output the force signal in response to tensioning the cable.

3. The exercise tracker of claim 1, further comprising a data storage medium, wherein the processor is programmed to store the exercise data in the data storage medium.

4. The exercise tracker of claim 1, further comprising a wireless communication device programmed to wirelessly transmit the exercise data.

5. The exercise tracker of claim 1, further comprising an accelerometer programmed to detect movement of the exercise tracker and output signals to the processor, wherein the processor is programmed to determine a number of calories burned based at least in part on the signals output by the accelerometer.

6. The exercise tracker of claim 1, further comprising a battery electrically connected to at least one of the force sensor and the processor.

7. The exercise tracker of claim 6, wherein the battery is configured to receive electrical energy generated by moving the cable.

8. The exercise tracker of claim 1, wherein the one of the plurality of protrusions is cantilevered from the base.

9. The exercise tracker of claim 8, wherein tensioning the cable deflects the one of the plurality of protrusions in a direction perpendicular to a direction of the tensioning of the cable.

10. The exercise tracker of claim 8, wherein the force sensor is disposed on or by at least one of the plurality of protrusions.

11. The exercise tracker of claim 1, wherein the cable includes a first cable segment and a second cable segment, and wherein the force sensor is disposed between the first and second cable segments and configured to measure a force applied to at least one of the first and second cable segments.

12. A system comprising:

a remote device; and

an exercise tracker, fixed to a cable of a piece of exercise equipment, and programmed to determine an amount of weight lifted and a number of repetitions performed in accordance with a deflection by the cable of one of a plurality of protrusions of the exercise tracker, wherein a location of the one of the plurality of protrusions is adjustable via a positioning screw,

wherein the piece of exercise equipment further includes a variable weight stack and a pulley for receiving the cable and wherein the exercise tracker is configured to attach to the cable between the pulley and the variable weight stack,

wherein the exercise tracker is programmed to wirelessly transmit the amount of weight lifted and the number of repetitions performed to the remote device, and

wherein the exercise tracker moves in accordance with movement of the cable.

13. The system of claim 12, wherein the exercise tracker includes a force sensor disposed on one of the plurality of protrusions and configured to detect a force applied to the cable and programmed to generate a force signal in accordance with the force applied to the cable.

14. The system of claim 12, wherein the exercise tracker includes a data storage medium programmed to store the amount of weight lifted and the number of repetitions performed.

15. The system of claim 12, wherein the exercise tracker includes a wireless communication device programmed to wirelessly transmit the amount of weight lifted and the number of repetitions performed to the remote device.

16. The system of claim 12, wherein the exercise tracker includes an accelerometer programmed to detect movement of the exercise tracker and generate signals corresponding to the movement of the exercise tracker, wherein the exercise tracker is programmed to determine the amount of weight lifted and the number of repetitions performed based at least in part on the signals generated by the accelerometer.

17. The system of claim 12, wherein the exercise tracker includes a base and wherein the one of the plurality of protrusions is cantilevered from the base.

18. The system of claim 17, wherein tensioning the cable deflects the one of the plurality of protrusions in a direction perpendicular to a direction of the tensioning of the cable.

19. The system of claim 12, wherein the exercise tracker is disposed on the cable between the pulley and the variable weight stack of the piece of exercise equipment.

20. An exercise system comprising:

exercise equipment having a variable weight stack, a pulley, and a cable attached to the variable weight stack and passed through the pulley; and

an exercise tracker attached to the cable, the exercise tracker having;

a base;

a plurality of protrusions extending from the base, wherein a location of one of the plurality of protrusions is adjustable via a positioning screw, and wherein the exercise tracker is configured to move vertically in accordance with movement of the cable;

a force sensor programmed to output a force signal representing a force applied to the cable; and

a processor programmed to receive the force signal and determine, from the force signal, exercise data including an amount of weight lifted.
