Abstract

Embodiments provide a tire pressure measurement device, an integrated circuit, a printed circuit board, a method and a computer program to receive data. The tire pressure measurement device includes a first receiver configured to receive a low frequency signal using a first low frequency input of the first receiver, and a second input configured to receive a receive signal associated with a second receiver that is different from the first receiver. The tire pressure measurement device further includes a controller configured to control the first low frequency input of the first receiver and to couple the second input to the first low frequency input of the first receiver in order for the first receiver to receive the receive signal at the first low frequency input.

Claims

1. A tire pressure measurement device for receiving data, comprising:

a first receiver comprising a first low frequency input configured to receive a low frequency signal; and

a controller configured to receive a receive signal, to control the first low frequency input of the first receiver, and to couple the receive signal to the first low frequency input of the first receiver in order for the first receiver to receive the receive signal at the first low frequency input,

wherein the low frequency signal and the receive signal originate from different sources.

2. The tire pressure measurement device of claim 1, wherein the receive signal comprises a frequency band outside a low frequency band used by the first receiver, and

the controller is configured to convert the receive signal into a low frequency receive signal, and output the low frequency receive signal to the first low frequency input of the first receiver.

3. The tire pressure measurement device of claim 1, further comprising:

a second input configured to receive the receive signal,

wherein the controller is configured to switchably couple the second input to the first low frequency input of the first receiver in order for the first receiver to receive the receive signal at the first low frequency input.

4. The tire pressure measurement device of claim 3, wherein the receive signal is associated with a second receiver that is different from the first receiver.

5. The tire pressure measurement device of claim 3, wherein the second input is configured to receive the receive signal using a radio frequency band that is outside a low frequency band used by the first receiver.

7. The tire pressure measurement device of claim 1, further comprising:

a second input configured to receive the receive signal, wherein the receive signal is a radio frequency receive signal having a radio frequency band that is outside a low frequency band used by the first receiver, and

the controller is configured to convert the radio frequency receive signal into a low frequency receive signal, and output the low frequency receive signal to the first low frequency input of the first receiver.

8. The tire pressure measurement device of claim 7, wherein the controller comprises a demodulator configured to demodulate the radio frequency receive signal into the low frequency receive signal.

9. The tire pressure measurement device of claim 8, wherein the demodulator comprises at least one non-linear electronic component.

10. The tire pressure measurement device of claim 9, wherein the at least one non-linear electronic component comprises at least one diode.

11. The tire pressure measurement device of claim 8, wherein the demodulator is configured to demodulate an Amplitude Modulated (AM) or an Amplitude-Shift-Keying (ASK)-modulated radio frequency receive signal into the low frequency receive signal.

12. The tire pressure measurement device of claim 1, further comprising:

a second receiver configured to receive the receive signal is-associated with a second receiver that is different from the first receiver;

a matching network for the second receiver; and

a radio frequency antenna.

13. The tire pressure measurement device of claim 1, further comprising:

a second input configured to receive the receive signal that is based on an acoustical receive signal.

14. The tire pressure measurement device of claim 9, further comprising:

an acoustical transducer configured to receive the acoustical receive signal and convert sound applied to a tire into an electrical signal as the receive signal.

15. The tire pressure measurement device of claim 14, wherein the acoustical transducer is configured to convert mechanical energy from tire deformation into electrical energy for powering the tire pressure measurement device.

16. The tire pressure measurement device of claim 15, wherein the acoustical transducer is further configured to carry out sound measurements.

17. The tire pressure measurement device of claim 1, wherein the controller is configured to couple and to decouple a second input with the first low frequency input, the second input configured to receive the receive signal.

18. The tire pressure measurement device of claim 1, further comprising:

a second input configured to receive the receive signal, wherein the controller is configured to switch the second input between the first low frequency input of the first receiver and at least one other signal.

19. The tire pressure measurement device of claim 1, further comprising:

a low frequency coil, wherein the controller is configured to couple the low frequency coil to the first low frequency input of the first receiver.

6. A tire pressure measurement device for receiving data, comprising:

a first receiver comprising a first low frequency input configured to receive a low frequency signal; and

a controller configured to receive a receive signal, to control the first low frequency input of the first receiver, and to couple the receive signal to the first low frequency input of the first receiver in order for the first receiver to receive the receive signal at the first low frequency input,

wherein the controller is configured to switchably couple a signal input configured to receive the low frequency signal and a second input configured to receive the receive signal in order for the first receiver to receive one of the low frequency signal or a low frequency receive signal at the first low frequency input, wherein the low frequency receive signal is derived from the receive signal.

20. A method for receiving data at a tire pressure measurement device, comprising:

controlling, by a controller, an input of a first receiver for receiving one of a low frequency signal and a low frequency receive signal derived from a receive signal; and

providing the receive signal from a second receiver, which is different from the first receiver, wherein the receive signal comprises a frequency band outside a low frequency band used by the first receiver.
