Abstract

An apparatus for calming a baby in an interior of a vehicle has a heartbeat sensor device (11, 12, 13) configured to capture a heartbeat input signal that depends on the heartbeat of an occupant in an interior (18) of a vehicle (10). A heartbeat signal processing device (14) is configured to produce a heartbeat output signal that depends on the heartbeat input signal. A calming signal output device (15, 16, 17) is configured to output a calming signal that depends on the heartbeat output signal and that is perceivable by a baby in the interior (19) of the vehicle (10). The apparatus is to configured to output the calming signal, at least intermittently, directly during the capture of the heartbeat input signal.

First claim

What is claimed is:

1. Apparatus for calming a baby in an interior of a vehicle, comprising:
a heartbeat sensor device configured to capture a heartbeat input signal that correlates with an actual heartbeat of an occupant in the interior of the vehicle, wherein the heartbeat sensor device is embedded in a seat of the vehicle;
a heartbeat signal processing device configured to produce a heartbeat output signal representative of the heartbeat of the occupant in response to the heartbeat input signal; and
a calming signal output device configured to output a calming signal reproducing the heartbeat output signal and that is perceivable by a baby in the interior of the vehicle, wherein the calming signal is output at least intermittently and is output substantially simultaneously with the capture of the corresponding heartbeat input signal.

2. The apparatus as claimed in claim 1 wherein the heartbeat sensor device comprises at least one microphone.

3. The apparatus as claimed in claim 1 wherein the heartbeat sensor device comprises at least one portable heartbeat measuring appliance.

4. The apparatus as claimed in claim 1 wherein the heartbeat signal processing device comprises a means for amplifying the heartbeat input signal in order to produce the heartbeat output signal.

5. The apparatus as claimed in claim 1 wherein the heartbeat signal processing device establishes a frequency of the captured heartbeat input signal.

6. The apparatus as claimed in claim 5 wherein the heartbeat signal processing device is configured to synthesize the heartbeat output signal on the basis of the established frequency.

7. The apparatus as claimed in claim 1 wherein the heartbeat signal processing device is configured to filter the heartbeat output signal depending on a gradient of a predetermined frequency curve.

8. The apparatus as claimed in claim 1 wherein the calming signal output device comprises at least one loudspeaker that is integrated in a baby seat.

9. The apparatus as claimed in claim 1 wherein the calming signal output device comprises headphones.

10. Apparatus for calming a baby in an interior of a vehicle, comprising:
a heartbeat sensor device configured to capture a heartbeat input signal that correlates with an actual heartbeat of an occupant in the interior of the vehicle, wherein the heartbeat sensor device is embedded in a steering wheel of the vehicle;
a heartbeat signal processing device configured to produce a heartbeat output signal representative of the heartbeat of the occupant in response to the heartbeat input signal; and
a calming signal output device configured to output a calming signal reproducing the heartbeat output signal and that is perceivable by a baby in the interior of the vehicle, wherein the calming signal is output at least intermittently and is output substantially simultaneously with the capture of the corresponding heartbeat input signal.

11. The apparatus as claimed in claim 10 wherein the heartbeat sensor device comprises at least one microphone.

12. The apparatus as claimed in claim 10 wherein the heartbeat sensor device comprises at least one portable heartbeat measuring appliance.

13. The apparatus as claimed in claim 10 wherein the heartbeat signal processing device comprises a means for amplifying the heartbeat input signal in order to produce the heartbeat output signal.

14. The apparatus as claimed in claim 10 wherein the calming signal output device comprises a plurality of loudspeakers of the vehicle and a control unit configured to emit the calming signal as audible sound perceivable by the baby in the vehicle, in a directly directed manner to a region of the interior of the vehicle occupied by the baby.

15. The apparatus as claimed in claim 10 wherein the calming signal output device comprises at least one loudspeaker that is integrated in a baby seat.

16. The apparatus as claimed in claim 10 wherein the calming signal output device comprises headphones.

17. Apparatus for calming a baby in an interior of a vehicle, comprising:
a heartbeat sensor device configured to capture a heartbeat input signal that correlates with an actual heartbeat of an occupant in the interior of the vehicle, wherein the heartbeat sensor device comprises at least one camera sensor that is alignable to view the face of the occupant;
a heartbeat signal processing device configured to produce a heartbeat output signal representative of the heartbeat of the occupant in response to the heartbeat input signal; and
a calming signal output device configured to output a calming signal reproducing the heartbeat output signal and that is perceivable by a baby in the interior of the vehicle, wherein the calming signal is output at least intermittently and is output substantially simultaneously with the capture of the corresponding heartbeat input signal.

18. The apparatus as claimed in claim 17 wherein the heartbeat signal processing device is configured to identify a variation of the heartbeat input signal from the camera signal related to the heartbeat, wherein the variation occurs in a color or brightness in a region of the face of the occupant, and to establish the heartbeat output signal therefrom.

19. Apparatus for calming a baby in an interior of a vehicle, comprising:
a heartbeat sensor device configured to capture a heartbeat input signal that correlates with an actual heartbeat of an occupant in the interior of the vehicle;
a heartbeat signal processing device configured to produce a heartbeat output signal representative of the heartbeat of the occupant in response to the heartbeat input signal; and
a calming signal output device configured to output a calming signal reproducing the heartbeat output signal and that is perceivable by a baby in the interior of the vehicle, wherein the calming signal is output at least intermittently and is output substantially simultaneously with the capture of the corresponding heartbeat input signal, wherein the calming signal output device comprises a plurality of loudspeakers of the vehicle and a control unit configured to emit the calming signal as audible sound perceivable by the baby in the vehicle, in a directly directed manner to a region of the interior of the vehicle occupied by the baby.
