Abstract

An apparatus and method for measuring exercise quantity through a film-type pressure sensor are provided. The apparatus for measuring exercise quantity through a film-type pressure sensor comprises a film-type pressure sensor to sense pulse pressure of a user'"'"'s body, a main body to calculate and display a heart rate (HR) and calories consumed based on the HR, and a band that is coupled to the main body and to which the film-type pressure sensor is attached. The band contains a first band portion which is coupled to the main body and a second band portion which contains the film-type pressure sensor and is coupled to the first band portion. The second band portion contains at least one projection to enhance the detection of the pulse pressure of the user.

Claims

1. An apparatus for measuring exercise quantity, the apparatus comprising:

a film-type pressure sensor which senses a pulse pressure of a body of a user;

a main body which calculates and displays a heart rate (HR) of the user and calories consumed by the user based on the HR; and

a band that is coupled to the main body and to which the film-type pressure sensor is attached.

2. The apparatus of claim 1, wherein the band comprises:

a first band part having a degree of elasticity, one end of which is coupled to a side of the main body;

a second band part being coupled to the other side of the first band part, to thereby protect the film-type pressure sensor;

at least one projection positioned on one side of the second band part, to enhance sensing of said pulse pressure; and

a wire which transmits the pulse pressure signal produced by the film-type pressure sensor to the main body.

3. The apparatus of claim 2, wherein the wire is positioned within the first band part.

4. The apparatus of claim 3, wherein if the first band part is in a non-extended state the wire is configured in a wave form such that the wire has a length longer than the first band part.

5. The apparatus of claim 2, wherein the second band part is non-elastic.

6. The apparatus of claim 2, wherein the film-type pressure sensor is surrounded by the second band part.

7. The apparatus of claim 2, wherein the wire is surrounded by the first band part.

8. The apparatus of claim 1, wherein the main body comprises:

a noise processor unit which removes noise generated as the user moves;

a calculator unit which calculates the HR based on the measured pulse pressure, and calculates the calories consumed during exercise based on the HR; and

a display unit which displays the HR and the consumed calories.

9. The apparatus of claim 8, wherein the main body further comprises:

a storage unit which stores the consumed calories and user information;

a Bluetooth module which receives the user information or music files from an external device; and

an MP3 module which plays the music files transmitted via the Bluetooth module.

10. The apparatus of claim 1, wherein the HR is a number of beats per minute.

11. A method for measuring exercise quantity using a film-type pressure sensor, comprising:

measuring the pulse pressure of a user who is exercising;

removing noise from the pulse pressure signal to provide a noise free pulse pressure;

calculating a heart rate (HR) of the user, based on the noise-free pulse pressure;

calculating the calories consumed by the user based on the HR; and

displaying the calories consumed and the HR.

12. The method of claim 11, wherein the pulse pressure is measured using the film-type pressure sensor.

13. The method of claim 11, wherein the removing the noise from the pulse pressure signal comprises:

checking whether a predetermined number of maximum values are input within a set time period;

determining whether the input maximum values are all smaller than a set critical value of a low pass filter and whether the input maximum values are larger than a set critical value of a high pass filter, when the predetermined number of maximum values are input;

calculating the mean of the input maximum values, if it is determined that the input maximum values are all smaller than the set critical value of the low pass filter, and changing the critical value of the low pass filter to the mean;

calculating the mean of the input maximum values, if it is determined that the input maximum values are all larger than the set critical value of the high pass filter, and changing the critical value of the high pass filter to the mean;

determining whether there is present any maximum value larger than the critical value of the high pass filter or smaller than that of the low pass filter; and

if it is determined that there is present a maximum value larger than the critical value of the high pass filter or smaller than that of the low pass filter, removing the maximum value present.

14. The method of claim 11, further comprising selecting a user profile if a plurality of users use the exercise quantity measuring apparatus.

15. The method of claim 11, further comprising selecting a type of exercise that the user will engage in.

16. The method of claim 11, further comprising measuring the pulse pressure of the user through at least one projection on a band coupled to a wrist of the user.
