Abstract

An exercise device configured to sense and respond to objects in proximity to the exercise device is provided. The device includes a sensor configured to sense objects in proximity to the exercise device other than the user who is operating the exercise device. A console is in communication with the sensor that instructs components of the treadmill to provide, for example, an audible and/or visual response to the user of the exercise device, or to slow or stop the exercise device from moving. Sensors that are capable of sensing whether objects are within different spatial zones of proximity are disclosed. Multiple pre-defined and/or user-defined responses to objects detected in multiple corresponding spatial zones of proximity are also disclosed herein.

Claims

1. An exercise device configured to sense objects outside the footprint of the exercise device, the exercise device comprising:

an exercise mechanism comprising a movable element for movement in performance of exercise by a user;

a sensor coupled to the exercise mechanism and configured to sense objects outside the footprint of the exercise mechanism; and

a controller in operative communication with the sensor and the movable element, wherein the controller is configured to provide a response to objects, other than a user using the exercise mechanism, sensed by the sensor that are outside the footprint of the exercise mechanism.

2. The exercise device of claim 1, wherein the exercise mechanism comprises a treadmill and the moveable element comprises a treadmill belt.

3. The exercise device of claim 1, wherein the sensor comprises a capacitance sensor, an infrared sensor, a laser distance measurement sensor, a metal detector, a motion detector, a photodetector, a proximity sensor, a thermal sensor, a video camera, an ultrasonic sensor, a sonar sensor, a radar sensor, or any combination thereof.

4. The exercise device of claim 1, wherein the exercise device comprises at least two sensors configured to sense objects outside the footprint of the exercise mechanism.

5. The exercise device of claim 1, wherein the sensor can differentiate between a plurality of spatial zones of proximity, and wherein the controller is configured to provide a first response to objects sensed by the sensor in a first of the plurality of spatial zones of proximity and to provide a second response to objects sensed in a second of the plurality of spatial zones of proximity.

6. The exercise device of claim 5, wherein at least one of the first response and the second response comprises a user-defined response.

7. The exercise device of claim 5, wherein at least one of the plurality of spatial zones of proximity comprises a user-defined spatial zone of proximity.

8. The exercise device of claim 5, wherein the first of the plurality of spatial zones of proximity comprises an area between about 6 feet and about 9 feet from the sensor, the second of the plurality of spatial zones of proximity comprises an area between about 3 feet and about 6 feet from the sensor, and a third of the plurality of spatial zones of proximity comprises an area between about 0 feet and about 3 feet from the sensor.

9. The exercise device of claim 1, wherein the response comprises an audible response, a visual response, a tactile response, an electric response, an adjustment of an operating parameter of the exercise device, or any combination thereof.

10. The exercise device of claim 1, wherein the sensor is configured to sense objects in an area adjacent the exercise mechanism that is generally elliptical in shape.

11. The exercise device of claim 1, wherein the sensor is configured to sense objects in an area adjacent the exercise mechanism that is generally conical in shape.

12. The exercise device of claim 1, wherein the sensor is coupled to a peripheral portion of the exercise mechanism.

13. A method for responding to objects outside the footprint of an exercise device, the method comprising:

providing an exercise device having a sensor in communication with a controller that controls functions of the exercise device;

sensing objects in the area outside the footprint of the exercise device with the sensor; and

providing a response to objects, other than a user using the exercise mechanism, sensed by the sensor that are outside the footprint of the exercise mechanism.

14. The method of claim 13, wherein the response comprises an audible response, a visual response, a tactile response, an electric response, an adjustment of an operating parameter of the exercise device, or any combination thereof.

15. The method of claim 13, wherein providing the response comprises providing tiered responses based upon locations of the objects sensed by the sensor.

16. The method of claim 13, wherein sensing the proximity of objects comprises sensing objects in the area around and outside the footprint of the exercise device.

17. An exercise device configured to sense and respond to objects outside the footprint of the exercise device, the exercise device comprising:

a frame;

a movable element operatively coupled to the frame for movement in performance of exercise by a user;

a sensor coupled to the frame or the movable element, wherein the sensor is configured to sense objects outside the footprint of the exercise device as the objects approach the exercise device and while the movable element is moving; and

a controller in operative communication with the sensor, wherein the controller is configured to provide a response to sensed objects, other than a user using the exercise mechanism, when the

sensor, wherein the console is configured to provide a response when the sensor senses objects approaching the exercise device, thereby warning the user of the exercise device of the approaching objects.

18. The exercise device of claim 17, wherein the exercise device is selected from the group consisting of treadmills, elliptical trainers, stair climbers, rowing machines, cross-country ski exercisers, gliders, and stationary bicycles.

19. The exercise device of claim 17, wherein the response provided by the controller comprises an audible response, a visual response, a tactile response, an electric response, an adjustment of an operating parameter of the exercise device, or any combination thereof.

20. The exercise device of claim 17, wherein the sensor comprises multiple sensors disposed about the exercise device to sense objects approaching any of multiple sides of the exercise device.
