Abstract

The present invention relates to a method and a device comprising a controller and a pressure sensor. The controller is configured to calibrate said pressure sensor based on a current position of said device and/or current pressure information received from a source.

Claims

1. A device comprising:

a wireless communication portion configured to communicate with an external wireless unit,

a pressure sensor, and

a controller configured to calibrate the pressure sensor based on pressure information received from said external unit.

2. The device of claim 1, wherein the external unit is a transmitter.

3. The device of claim 1, wherein the external unit is a radio transmitter comprising a memory including the position and/or pressure information.

4. The device of claim 1, wherein the external unit is a Near Filed Communication (NFC) tag or Radio Frequency Identity (RFID) tag.

5. The device of claim 1, wherein the external unit is configured to be updated.

6. The device according to claim 1, wherein current pressure information comprises one or several of:

a current position of the external unit,

a unique identity of the external unit, or

information related to altitude of the external unit.

7. The device according to claim 1, being one of a radiotelephone having ability for near field communication or Internet/intranet access, a global navigation satellite system (GNSS) receiver, a personal communications system (PCS) terminal, a personal digital assistant (PDA), a camera having communication ability, and a computation or communication device capable of transceiving.

8. A transceiver device comprising a communication part, a controller and a memory, wherein said controller is configured to transmit through said communication part a pressure relevant data upon inquiry.

9. The device of claim 8, being one a Near Filed Communication, NFC, tag or Radio Frequency Identity, RFID, tag.

10. The device according to claim 8, wherein said pressure relevant data includes:

current position of the device, and

current pressure information comprises one or several of;

an altitude of the external unit,

a unique identity of the external unit, or

altitude related information of the external unit.

11. A method of calibrating a pressure sensor, the method comprising:

Obtaining a position and/or pressure value,

Using the pressure value or a value obtained through the position to set a new value in the sensor for use as relative pressure value.
