Patent ID: 7912514

Claim:
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.
