Abstract

Contact pressure sensing apparatus for use with exercise equipment sensors are described. An example apparatus includes a sensor to detect a physiological condition of a user of an exercise device through physical contact with the user and a pressure sensor to detect a contact pressure applied by the user to the sensor.

Claims

1. An apparatus for use with an exercise device, comprising:

a physiological condition sensor to detect a physiological condition of a user of the exercise device through physical contact with the user;

a pressure sensor to detect a contact pressure applied by the user to the physiological condition sensor; and

a processor configured to compare the detected contact pressure with a threshold amount of pressure associated with an ability of the physiological condition sensor to detect the physiological condition, wherein the processor is configured to calculate a percentage representative of an accuracy of a reading of the physiological condition by the physiological condition sensor based on the comparison between the detected contact pressure and the threshold amount of pressure.

2. An apparatus as defined in claim 1, wherein the physiological condition is a heart rate.

3. An apparatus as defined in claim 1, wherein the physiological condition sensor to detect the physiological condition comprises an electrode.

4. An apparatus as defined in claim 1, wherein the pressure sensor is located between the physiological condition sensor and a frame of the exercise device.

5. An apparatus as defined in claim 1, wherein the processor is configured to cause the display to present the physiological condition.

6. An apparatus as defined in claim 1, wherein the processor is configured to cause a change in an operation of the exercise machine based on the physiological condition.

7. An apparatus as defined in claim 1, wherein the processor is configured to cause the display to present information associated with the contact pressure.

8. An apparatus as defined in claim 7, wherein the displayed information associated with the contact pressure comprises a difference between the detected contact pressure and the threshold amount of pressure.

9. An apparatus as defined in claim 1, wherein the processor is configured to cause presentation of an indication of how close the user is to attaining the threshold amount of pressure.

10. An apparatus as defined in claim 1, wherein the threshold amount of pressure is a non-zero value.

11. An apparatus as defined in claim 1, wherein the processor is configured to use the comparison to determine whether a sufficient amount of pressure is being applied by the user for the physiological condition sensor to accurately detect the physiological condition.

12. An apparatus as defined in claim 1, wherein the processor is configured to withhold a result of a reading of the physiological condition taken by the physiological condition sensor from the display based on the comparison of the detected contact pressure to the threshold amount of pressure.

13. An apparatus as defined in claim 1, wherein the processor is to cause a display to present an instruction to increase or decrease the contact pressure based on the comparison of the detected contact pressure and the threshold amount of pressure.

14. An apparatus as defined in claim 1, wherein the processor is configured to determine whether an excessive amount of weight of the user is being supported by arms of the user based on the detected contact pressure.

15. An apparatus for use with an exercise device, comprising:

means for detecting a physiological condition of a user of the exercise device through physical contact with the user;

means for detecting a contact pressure applied by the user to the means for detecting the physiological condition of the user; and

means to compare the detected contact pressure with a threshold amount of pressure associated with an ability of the means for detecting the physiological condition to detect the physiological condition; and

means to calculate a percentage representative of an accuracy of information generated by the means for detecting the physiological condition based on the comparison of the detected contact pressure to the threshold amount of pressure.

16. An apparatus as defined in claim 15, further comprising means to display a difference between the detected contact pressure and the threshold amount of pressure.

17. An apparatus as defined in claim 15, wherein the threshold amount of pressure is a non-zero value.

18. An apparatus as defined in claim 15, further comprising means to display an instruction to increase or decrease the contact pressure based on the comparison of the detected contact pressure and the threshold amount of pressure.

19. An apparatus for use with an exercise device, comprising:

a physiological condition sensor to detect a physiological condition of a user of the exercise device through physical contact with the user;

a pressure sensor to detect a contact pressure applied by the user to the physiological condition sensor;

a display to present information related to the detected physiological condition; and

a processor configured to compare the detected contact pressure with a threshold amount of pressure associated with an ability of the physiological condition sensor to detect the physiological condition, wherein the processor is configured to calculate an accuracy of the information displayed in connection with the physiological condition based on the comparison of the detected contact pressure to the threshold amount of pressure.

20. An apparatus as defined in claim 19, wherein the processor is configured to cause the display to present the user with a difference between the detected contact pressure and the threshold amount of pressure.

21. An apparatus as defined in claim 19, wherein the processor is configured to cause the display to present the user with an instruction to increase or decrease a grip pressure based on the comparison of the detected contact pressure and the threshold amount of pressure.

22. An apparatus as defined in claim 19, wherein the processor is configured to withhold a result of a reading of the physiological condition taken by the physiological condition sensor from a display based on the comparison of the detected contact pressure to the threshold amount of pressure.
