Abstract

A new method and system are presented to drastically reduce the power absorbed by the body of the user'"'"'s of mobile or wireless computing or communication devices, such as cell phones, so that the usage of those devices become safe for the users. In one case, multiple antennas are used, and the transmission is done in multiple steps or stages. The first antenna (the closest to the user) operates with extremely low power for short distances. In addition, the distance between the user and the last antenna is increased drastically. In another case, multiple frequencies are used, in combination with multiple antennas. The frequency chosen for the first antenna is selected from a range of frequencies corresponded to the low power absorption for a specific human tissue or for overall human body, as a weighted average. Other variations are also described in detail.

5. A system as recited in claim 2, said system further comprising a radiation shield.

6. A system as recited in claim 2, wherein said first antenna, said last antenna, or both are retractable antennas.

7. A system as recited in claim 2, wherein said first antenna, said last antenna, or both are attached to or included in one of an ear-piece, a handset, or a headset.

8. A system as recited in claim 2, wherein said system is compatible with Bluetooth-enabled appliances or devices.

9. A system as recited in claim 2, wherein said system is used in a car.

10. A system as recited in claim 2, said system further comprising a hands-free device.

11. A system as recited in claim 2, wherein said system is used in at least one of computation device, pager, radio, PDA, computer-game device, e-book reader, music-player, video-player, rendering device, global positioning system, hand-held device, appliance, PC, computer, one-way or two-way communication system, tracking device, broadcasting device, or narrow-casting device.

12. A system as recited in claim 2, wherein a third antenna is inserted between said first antenna and said last antenna, wherein said first antenna transmits said data to said third antenna, and said third antenna transmits said data to said last antenna.

13. A system as recited in claim 2, wherein N antennas are inserted between said first antenna and said last antenna, wherein said N antennas are positioned in series, and wherein N is an integer larger than 1.

14. A system as recited in claim 2, wherein N antennas are inserted between said first antenna and said last antenna, wherein said N antennas are positioned in parallel, and wherein N is an integer larger than 1.

15. A system as recited in claim 2, said system further comprising N other antennas,

wherein said N other antennas transmit said data to a central antenna,

wherein said central antenna transmits said data to at least one of said last antenna or said location outside said system, and

wherein N is an integer larger than zero.

16. A system as recited in claim 2, wherein transmission of said data between said first antenna and said last antenna is done at first frequency, and

transmission of said data between said last antenna and said location outside said system is done at second frequency,

wherein said second frequency is different than said first frequency.

17. A system as recited in claim 16, wherein said second frequency is chosen from a range of 800 MHz-2.4 GHz.

18. A system as recited in claim 16, wherein said first frequency is chosen from a range of frequency which corresponds to a low radiation power absorption for a specific tissue or part of human body.
