Abstract

A carrier system includes at least one seat and a radio wave detection device. The radio wave detection device is configured to emit a detection wave towards at least one seat of the carrier. A reflected wave reflected in response to the detection wave is received by the radio wave detection device. A position of an occupied seat and a type of an occupant on the occupied seat are determined in response to the received reflected wave. A safety mechanism is activated in response to the position of the occupied seat and the type of the occupants.

Claims

1. A method implemented by a carrier system, the method comprising:

emitting a detection wave by a radio wave detection device and receiving a reflected wave reflected in response to the detection wave;

determining the received reflected wave whether includes a characteristic frequency; and

activating a safety mechanism in response to the position of the occupied seat and a type of an occupant.

2. The method of claim 1, wherein the characteristic frequency includes physiological information relevant to heart beating or breathing.

3. The method of claim 1 further comprising:

obtaining a detection distance by calculating a time of flight (TOF) between the detection wave and the reflected wave; and

determining a type of the occupant by comparing the detection distance with a pre-determined distance;

wherein the pre-determined distance includes a distance between the radio wave detection device and the occupied seat.

4. The method of claim 1, wherein the radio wave detection device includes at least one radio wave transceiver which is respectively arranged in response to the at least one seat.

5. The method of claim 4, wherein the at least one radio wave transceiver moves in a rotational manner to detect the at least one seat.

6. The method of claim 4, wherein the at least one radio wave transceiver is disposed in response to different reception beam angles.

7. The method of claim 6, wherein the at least one radio wave transceiver moves in a rotational manner to detect different positions, along a vertical direction, of the at least one seat.

8. The method of claim 1, wherein the safety mechanism includes delivering an alert message when an accident occurs.

9. The method of claim 1, wherein the safety mechanism includes activating at least one airbag when an accident occurs.

10. A carrier including a carrier system, comprising:

at least one seat; and

a radio wave detection device configured to emit a detection wave towards the at least one seat and receive a reflected wave reflected in response to the detection wave, and determine a position of an occupied seat and a type of an occupant on the occupied seat in response to the reflected wave, and activate a safety mechanism in response to the position of the occupied seat and the type of the occupants.

11. The carrier of claim 10, wherein the safety mechanism is configured to deliver an alert message or activate at least one airbag when an accident occurs.

12. The carrier of claim 10, wherein the radio wave detection device comprises a processor configured to determine whether the reflected wave includes a characteristic frequency in response to heart beating or breathing of the occupant.

13. The carrier of claim 12, wherein the processor configured to obtain a detection distance by calculating a time of flight (TOF) between the detection wave and the reflected wave, and map the detection distance with a pre-determined distance between the radio wave detection device and the occupied seat.

14. The carrier of claim 10, wherein the radio wave detection device includes at least one radio wave transceiver facing toward the at least one seat, and the radio wave transceiver configured to emits the detection wave towards a pre-determined position of the at least one seat and receives the reflected wave reflected by the pre-determined position of the at least one seat.

15. The carrier of claim 14, wherein the at least one radio wave transceiver moves in a rotational manner to detect the at least one seat.

16. The carrier of claim 10, wherein the at least one radio wave transceiver is disposed in response to different reception beam angles.

17. The carrier of claim 16, wherein the at least one radio wave transceiver moves in a rotational manner to detect different positions, along a vertical direction, of the at least one seat.

18. The carrier of claim 10, wherein the radio wave detection device is disposed above the at least one seat.

19. The carrier of claim 10, wherein the radio wave detection device is disposed in front of the at least one seat.
