Abstract

The present disclosure herein relates to a system for monitoring a user using a pulse signal. An user monitoring system according to an embodiment of the present invention may comprise a transmitter configured to transmit a pulse signal through at least one antenna at different times; and a biosignal measuring device comprising a receiver for receiving and restoring the pulse signal that has passed through a subject through at least one antenna and a processing unit for processing the pulse signal to analyze at least one of a bandwidth, a center frequency or an amplitude of the pulse signal and for measuring a biosignal of the subject on the basis of a result of analysis.

Claims

1. A user monitoring system comprising:

a transmitter configured to transmit a pulse signal through at least one antenna at different times; and

a biosignal measuring device comprising a receiver and a processing unit,

wherein the receiver receives and restores the pulse signal that has passed through a subject through at least one antenna, and

wherein the processing unit processes the pulse signal to analyze at least one of a bandwidth, a center frequency and an amplitude of the pulse signal and measures a biosignal of the subject on the basis of a result of analysis.

2. The user monitoring system of claim 1, wherein a pulse of the pulse signal is repeated at a preset pulse repetition period.

3. The user monitoring system of claim 1, wherein the transmitter comprises a delay unit configured to provide, to the at least one antenna of the transmitter, a plurality of pulse signals obtained by different delays to the pulse signal.

4. The user monitoring system of claim 1, wherein the receiver comprises:

a delay unit configured to apply different delays to a plurality of pulse signals received by the at least one antenna of the receiver; and

an adder configured to add the plurality of pulse signals output by the delay unit.

5. The user monitoring system of claim 1, wherein the transmitter and the receiver are synchronized with each other to share a clock signal.

6. The user monitoring system of claim 1, wherein the user monitoring system is provided to a vehicle to monitor the subject in the vehicle.

7. The user monitoring system of claim 6, wherein the at least one antenna of the transmitter is installed in a steering wheel of the vehicle, and the at least one antenna of the receiver is installed in a back of a driver'"'"'s seat of the vehicle.

8. The user monitoring system of claim 6, wherein the at least one antenna of the transmitter is installed at a front upper part in the vehicle, and the at least one antenna of the receiver is installed in a back of a seat of the vehicle.

9. The user monitoring system of claim 8, wherein a plurality of antennas are such arranged that the antennas are flush with each other and form a shape of a polygon.

10. The user monitoring system of claim 9, further comprising an antenna disposed at a center of the polygon.

11. The user monitoring system of claim 8, further comprising:

an input device configured to receive information on the seat of the vehicle on which the subject is seated,

wherein the transmitter transmits the pulse signal towards the at least one antenna installed in the back of the seat on which the subject is seated.

12. The user monitoring system of claim 11, wherein, in the case where the subject is seated on a plurality of seats, the transmitter transmits the pulse signal towards the at least one antenna installed in a back of each seat on which the subject is seated at different times.

13. The user monitoring system of claim 6, further comprising:

an input device configured to receive information on a physique of the subject in the vehicle,

wherein the receiver comprises a first antenna group installed in a first part of a back of a seat of the vehicle and a second antenna group installed in a second part of the back of the seat,

wherein the transmitter transmits the pulse signals towards one of the first and second antenna groups which corresponds to the physique of the subject.
