Abstract

The present invention is directed to a system for monitoring a physiological parameter of a cyclist, and methods of using the system. The system comprises a garment, a sensor, and a signal processor. The garment is configured to be worn by the cyclist. The sensor is fixedly coupled to the garment and configured to measure a signal representative of the physiological parameter during pedaling. The signal processor is operatively coupled to the sensor and configured to determine a diagnosis based on the measured signal. An alert is generated in response to the diagnosis substantially in real time.

Claims

1. A system for monitoring a physiological parameter of a cyclist, comprising:

a garment configured to be worn by the cyclist;

a plurality of sensors including one or more sensors fixedly coupled to a crotch portion of the garment and configured to measure a perineal arterial occlusion force;

a signal processor operatively coupled to the sensor, wherein the signal processor is configured to

receive a signal from one or more sensors of the plurality of sensors, the signal indicative of the measured perineal arterial occlusion force,

receive a user-selected perineal arterial occlusion force level, and

generate an alert in response to the measured perineal arterial occlusion force;

wherein the garment is configured to position the one or more sensors fixedly coupled to the crotch portion of the garment proximate the left and right pudendal arteries of the cyclist when the garment is worn by the cyclist; and

wherein the signal processor is configured to generate the alert based on a comparison of the measured perineal arterial occlusion force and a user-selected perineal arterial occlusion force level.

2. The system of claim 1 further comprising a data storage operatively coupled to the sensor and configured to record the signal.

3. The system of claim 1 further comprising a display device operatively coupled to the signal processor and configured to generate a display in response to the signal substantially in real time.

4. The system of claim 3, wherein the display device is coupled to a handlebar of a bicycle.

5. The system of claim 3, wherein the display comprises a listing of one or more parameters selected from a group consisting of arterial force, lung capacity, weight, wattage output, spine alignment, posture, respiratory rate, perspiration rate, heart rate, muscle group use, and hydration.

6. The system of claim 1, wherein the one or more sensors are configured to generate the signal indicative of the measured perineal arterial force at predetermined intervals.

7. The system of claim 1 further comprising a signal transmission network operatively coupled to the plurality of sensors and the signal processor and configured to transmit the signal indicative of the measured perineal arterial occlusion force according to at least one network interface selected from a group consisting of a wired interface and a wireless interface.

8. The system of claim 1, wherein each of the plurality of sensors is one of a pressure sensor and a force sensor.

9. The system of claim 1, wherein the signal processor is configured to generate a comparison of the measured signal with a network of cyclists substantially in real time.

10. The system of claim 1, further comprising one or more straps each coupled to an additional sensor of the plurality of sensors, and wherein adjusting the straps re-positions the additional sensor with respect to the garment.

11. The system of claim 1, further comprising one or more straps each coupled to an additional sensor of the plurality of sensors, and wherein adjusting the straps re-positions the additional sensor with respect to the cyclist when the garment is worn by the cyclist.

12. The system of claim 1, wherein at least one additional sensor of the plurality of sensors is coupled to the garment by at least one fastener selected from a group consisting of hook-and-loop fasteners and adhesive tape.

13. The system of claim 1, wherein the plurality of sensors includes a sensor configured to monitor respiratory rate.

14. The system of claim 1, wherein the signal processor is configured to generate the alert based on the comparison of the measured perineal arterial occlusion force and the user-selected perineal arterial occlusion force level by generating the alert when the measured perineal arterial occlusion force exceeds a predetermined percentage of the user-selected perineal arterial occlusion force level.

15. The system of claim 1, wherein the signal processor is configured to receive the user-selected perineal arterial occlusion force level by receiving a user-selected percentage, and

wherein the signal processor is configured to generate the alert based on the comparison of the measured perineal arterial occlusion force and the user-selected perineal arterial occlusion force level by generating the alert when the measured perineal arterial occlusion force exceeds the user-selected percentage of a predetermined perineal arterial occlusion force level.

16. The system of claim 1, wherein the plurality of sensors are further configured to measure at least one additional parameter selected from a group consisting of weight, heart rate, blood pressure, and a combination thereof.

17. The system of claim 1, wherein the plurality of sensors are further configured to measure a cadence of the cyclist, and wherein the signal processor is configured to monitor the signal indicative of the measured perineal arterial occlusion force at a data acquisition frequency defined at least in part by the measured cadence of the cyclist.
