Abstract

A receiver apparatus is configured to receive a first and second signal from one or more sensors, the first signal comprising a measure of one or more exercise parameters of the user at a first time period of an exercise session, and the second signal comprising a measure of the one or more exercise parameters at a second time period. A processor is configured to store the first and second signals in a memory, generate a fatigue signal based on a comparison of the measured one or more exercise parameters of the first signal to the respective measured one or more exercise parameters of the second signal, generate an exercise efficiency signal based on a comparison of the measured one or more exercise parameters of the second signal to an a priori exercise parameter threshold, and cause the exercise efficiency signal and the fatigue signal to be simultaneously displayed.

First claim

What is claimed is:

1. A device for use by a user, the device comprising:
a receiver apparatus configured to:
receive a first signal comprising a measure of one or more exercise parameters of the user at a first time period of an exercise session, the first signal being received from one or more sensors;
receive a second signal comprising a measure of the one or more exercise parameters of the user at a second time period of the exercise session, the second time period different from the first time period, the second signal being received from the one or more sensors; and

a processor configured to:
store the first and second signals in a memory associated to the processor;
generate a fatigue signal based on a comparison of the measured one or more exercise parameters of the first signal to the respective measured one or more exercise parameters of the second signal;
generate an exercise efficiency signal based on a comparison of the measured one or more exercise parameters of the second signal to an a priori exercise parameter threshold; and
cause the exercise efficiency signal and the fatigue signal to be simultaneously displayed on a display device.

2. The device of claim 1 , wherein the fatigue signal is inversely related to the exercise efficiency signal.

3. The device of claim 1 ,
wherein the one or more sensors from which the first signal is received are configured to detect the cadence of the user at the first time;
wherein the one or more sensors from which the second signal is received are configured to detect the cadence of the user at the second time; and
wherein the fatigue signal is based on a change in cadence of the user from the first time to the second time.

4. The device of claim 1 ,
wherein the one or more sensors from which the first signal is received are configured to detect the loft of the first foot of the user at the first time;
wherein the one or more sensors from which the second signal is received are configured to detect the loft of the first foot of the user at the second time; and
wherein the fatigue signal is based on a change in the loft of the first food of the user from the first time to the second time.

5. The device of claim 1 , wherein the efficiency signal is based on a comparison of the measured one or more exercise parameters of the first signal to a predetermined threshold therefor and/or a comparison of the one or more exercise parameters of the second signal to a predetermined threshold therefor.

6. The device of claim 5 , wherein the fatigue signal is based on a comparison of the measured one or more exercise parameters of the first signal to a predetermined threshold therefor and/or a comparison of the one or more exercise parameters of the second signal to a predetermined threshold therefor.

7. The device of claim 1 ,
wherein the one or more exercise parameters of the user at the first time period includes at least one of: a heartrate of the user, a cadence of the user, a speed of the user, and a loft of a first foot of the user; and
wherein the one or more exercise parameters of the user at the second time period includes at least one of: the heartrate of the user, the cadence of the user, a speed of the user, and a loft of a first foot of the user.

8. The method of claim 1 , wherein the one or more sensors include a sensor mounted in a shoe.

9. A method comprising:
receiving a first detected signal based on a first parameter detected at a first time, the first parameter comprising at least one of: a heartrate of the user, a cadence of the user, a speed of the user, and a loft of a foot of the user;
receiving a second detected signal based on a second parameter detected at a second time, the second parameter either (i) a different parameter than the first parameter and comprising at least one of: the heartrate of the user, the cadence of the user, the speed of the user, and the loft of the foot of the user, wherein the second parameter is detected at the first time, or (ii) a same parameter as the first parameter; and
generating, via an efficiency generating component, an efficiency signal;
wherein, when the second parameter is a same parameter as the first parameter, the efficiency signal is generated based on a comparison of the first detected signal to the second detected signal; and
wherein, when the second detected parameter is a different parameter than the first parameter, the efficiency signal is generated based on a comparison of the first detected signal and the second detected signal to respective predetermined thresholds therefor.

10. The method of claim 9 , further comprising generating, via a fatigue generating component, a fatigue signal, and causing a fatigue signal and the efficiency signal to be simultaneously displayed on a display device.

11. The method of claim 9 ,

15. The method of claim 9 , further comprising causing at least one of the efficiency signal and the fatigue signal to be displayed at a display device.

16. A non-transitory, tangible, computer-readable media having computer-readable instructions stored thereon, the computer-readable instructions being capable of being read by a computer and being capable of instructing the computer to:
receive a first sensed parameter of the user at a first time, the first sensed parameter selected from a first group of parameters for the user;
