Abstract

An electrical power generator that generates power based on a carrier frequency of a received signal, a mobile terminal provided with the same and a control method thereof are discussed. The mobile terminal according to an embodiment includes an electrical power generator to generate an electrical energy based on a carrier frequency separated from a signal received from a base station.

Claims

1. An electrical power generator included in a mobile terminal, the electrical power generator comprising:

a receiving unit to receive a synthesized signal from an information provider, said synthesized signal including an information/data signal synthesized with a carrier frequency;

a separation unit to separate the carrier frequency from the received synthesized signal; and

an electrical energy generation unit to determine if the information/data signal is a voice call signal for the mobile terminal, and to selectively generate an electrical energy when the voice call data signal is received, using only the separated carrier frequency by converting the separated carrier frequency into the electrical energy if the information/data signal is the voice call signal for the mobile terminal,

wherein the electrical energy generation unit comprises;

an inverse oscillator unit including a material having an inherent frequency and resonating by the separated carrier frequency;

an application unit to apply the separated carrier frequency to the inverse oscillator unit; and

a conversion unit to convert kinetic energy of the resonating material into the electrical energy.

2. The electrical power generator of claim 1, wherein the information provider is a base station in a mobile communication system.

3. A mobile terminal, comprising:

a transceiver to send and receive communication signals with a communications network over a wireless interface; and

an electrical power generator including a receiving unit to receive a synthesized signal from an information provider, said synthesized signal including an information/data signal synthesized with a carrier frequency, a separation unit to separate the carrier frequency from the received synthesized signal, and an electrical energy generation unit to determine if the information/data signal is a voice call signal for the mobile terminal, and to selectively generate an electrical energy when the voice call data signal is received using only the carrier frequency separated from the received synthesized signal by converting the separated carrier frequency into the electrical energy if the information/data signal is the voice call signal for the mobile terminal,

wherein the electrical energy generation unit comprises;

an inverse oscillator unit including a material having an inherent frequency and resonating by the separated carrier frequency;

an application unit to apply the separated carrier frequency to the inverse oscillator unit; and

a conversion unit to convert kinetic energy of the resonating material into the electrical energy.

4. The mobile terminal of claim 3, wherein the receiving unit is a single antenna.

5. The mobile terminal of claim 3, wherein the carrier frequency is in the range of 750 MHz to 850 MHz.

6. The mobile terminal of claim 3, wherein the carrier frequency is in the range of 1.8 GHz to 1.9 GHz.

7. The mobile terminal of claim 3, further comprising a charging unit to charge a battery of the mobile terminal based on the generated electrical energy.

8. The mobile terminal of claim 3, further comprising a power supply unit to supply the generated electrical energy directly to components of the mobile terminal consuming power.

9. A method of controlling a mobile terminal, the method comprising:

receiving from a base station a synthesized signal including an information/data signal synthesized with a carrier frequency;

separating the carrier frequency from the received synthesized signal;

determining if the information/data signal is a voice call signal for the mobile terminal; and

selectively generating an electrical energy when the voice call data signal is received using only the separated carrier frequency by converting the separated carrier frequency into the electrical energy if the information/data signal is the voice call signal for the mobile terminal.

10. The method of claim 9, further comprising charging a battery of the mobile terminal based on the generated electrical energy.

11. The method of claim 9, further comprising supplementing power consumed by the mobile terminal and its additional equipment with the generated electrical energy.
