Wireless device detection and communication apparatus and system

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.

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.

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.

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