Abstract

A method for effecting a near field communication, including the steps of positioning a first device at a close proximity to a second device, wherein the close proximity is suitable for the near field communication; and sending a first effectively carrierless signal from the first device to the second device.

Claims

1. A method for effecting a near field communication, including the steps of:

providing a first device including a transmitting element for sending a first effectively carrierless signal and an accelerometer for detecting a movement of the first device for selectively preventing the first device from sending the first carrierless signal when the movement of the first device is less than a predetermined threshold;

positioning first device at a close proximity to the second device, wherein the close proximity is suitable for a near field communication;

sending the first effectively carrierless signal from the first device to the second device; and

establishing a wireless link between the first device and the second device, based on the first effectively carrierless signal.

2. The method of claim 1, wherein the first effectively carrierless signal includes a pulse.

3. The method of claim 1, wherein the first effectively carrierless signal includes a series of pulses.

4. The method of claim 1, wherein the first effectively carrierless signal includes a temporal oscillating signal.

5. The method of claim 1, wherein the step of sending the first effectively carrierless signal causes the step of:

sending a second effectively carrierless signal from the second device to the first device.

6. The method of claim 5, wherein the step of sending the second effectively carrierless signal causes the step of:

establishing a wireless link for data transfer between any two of the first device, the second device, and a third device.

7. The method of claim 1, wherein the second device is a device compliant with a first NFC protocol, and the sending of the first effectively carrierless signal allows the second device to communicate with the first device using the first NFC protocol.

8. A method for effecting a near field communication, including the steps of:

providing an accelerometer in a first device;

positioning the first device at a close proximity to a second device, wherein the close proximity is suitable for the near field communication;

sending a first carrierless signal from the first device to the second device; and

establishing a wireless link between the first device and the second device, based on the first carrierless signal;

detecting a movement of the first device by the accelerometer; and

preventing the first device from sending the first carrierless signal when the movement of the first device is less than a predetermined threshold.

9. A device, including:

a transmitting element for sending a first effectively carrierless signal to a second device when the device is positioned at a close proximity to the second device, wherein the close proximity is suitable for a near field communication; and

an accelerometer for detecting a movement of the device for preventing the device from sending the first carrierless signal when the movement of the device is less than a predetermined threshold.

10. The device of claim 9, further including:

a first receiving element for receiving a second effectively carrierless signal from the second device.

11. The device of claim 10, wherein the first effectively carrierless signal and the second effectively carrierless signal establish a wireless link for data transfer between any two of the first device, the second device, and a third device.

12. The device of claim 9, wherein the second device is a device compliant with a first NFC protocol, and the sending of the first effectively carrierless signal allows the second device to communicate with the first device using the first NFC protocol.

15. The device of claim 9, further including:

a communication mechanism having a first communicating element compliant to a first NFC protocol;

wherein the transmitting element and the first communicating element are the same element.

13. A device, including:

a transmitting element for sending a first effectively carrierless signal to a second device when the device is positioned at a close proximity to the second device, wherein the close proximity is suitable for a near field communication;

a first receiving element for receiving a second effectively carrierless signal from the second device;

a rechargeable power storage medium for supplying power to the device;

a second receiving element for receiving a charging field from the second device; and

a circuit for using the charging field to charge the rechargeable power storage medium.

14. The device of claim 13, wherein, in the presence of the charging field, the device load modulates the charging field at a regular predetermined interval.

16. The device of claim 14, wherein the first receiving element and the second receiving element are the same element.
