Abstract

Provided is a waist belt for automatically measuring a waist circumference. The waist belt includes a belt part (10) and a buckle part (20). The belt part has a plurality of magnets (11) attached thereto at a predetermined interval. The buckle part includes two or more magnetic field sensors sensing the plurality of magnets attached to the belt part, an operation processor processing and analyzing signals obtained by the magnetic field sensors, and a display displaying a measurement result of a waist circumference obtained by the operation processor.

Claims

1. A waist belt for automatically measuring a waist circumference comprising:

a belt part having a plurality of magnets attached thereto at a predetermined interval between each of the plurality of magnets; and

a buckle part comprising;

two or more magnetic field sensors sensing the plurality of magnets attached to the belt part;

an operation processor processing and analyzing signals obtained by the magnetic field sensors to calculate a waist circumference according to the plurality of magnets that the two or more magnetic field sensors sensed and the predetermined interval between each of the plurality of magnets; and

a display displaying a measurement result of the calculated waist circumference.

2. The waist belt of claim 1, wherein polarities of the plurality of magnets are alternately disposed.

3. The waist belt of claim 1, wherein the buckle part further comprises a user manipulating unit to receive a manipulating input from a user.

4. The waist belt of claim 1, wherein the buckle part further comprises a guard to prevent the belt part from shaking when the belt part is inserted into the buckle part.

5. The waist belt of claim 1, wherein an interval between the magnetic field sensors is an integer close to a value which is ±

¼

or ±

½

times the predetermined interval between the magnets that are attached to the belt part.

6. The waist belt of claim 1, wherein the buckle part further comprises a storage storing the measurement result of the calculated waist circumference obtained by the operation processor.

7. The waist belt of claim 6, wherein the buckle part further comprises a transmitter transmitting the measurement result of the calculated waist circumference stored in the storage to an external terminal in a wired or wireless manner.

8. The waist belt of claim 7, wherein the external terminal comprises a personal computer, a personal digital assistant (PDA), and a mobile terminal.

9. A waist belt for automatically measuring a waist circumference comprising:

a belt part having a plurality of magnets attached thereto at a predetermined interval between each of the plurality of magnets; and

a buckle part comprising;

two or more magnetic field sensors sensing the plurality of magnets attached to the belt part;

an operation processor processing and analyzing signals obtained by the magnetic field sensors to calculate the waist circumference according to the plurality of magnets that the two or more magnetic field sensors sensed and the predetermined interval between the each of the plurality of magnets;

a storage storing a measurement result of the calculated waist circumference; and

a transmitter transmitting the measurement result of the calculated waist circumference stored in the storage to an external terminal in a wire or wireless manner.

10. The waist belt of claim 9, wherein polarities of the plurality of magnets are alternately disposed.

11. The waist belt of claim 9, wherein the buckle part further comprises a user manipulating unit to receive a manipulating input from a user.

12. The waist belt of claim 9, wherein the buckle part further comprises a guard to prevent the belt part from shaking when the belt part is inserted into the buckle part.

13. The waist belt of claim 9, wherein an interval between the magnetic field sensors is an integer close to a value which is ±

¼

or ±

½

times of the predetermined interval between the magnets that are attached to the belt part.

14. The waist belt of claim 9, wherein the external terminal comprises a personal computer, a personal digital assistant (PDA), and a mobile terminal.
