## Abstract

An environmental energy absorption system for providing power to an electronic device comprising a remote station that includes an energy receiver; an energy converter for converting the received energy into electrical power and an energy storage element for storing the electrical power. The device uses environmental energy absorption to power the electronic device in the absence of a power supply source.

## Claims

### Claim 1

An environmental energy absorption system for providing power to an electronic device, comprising:
a remote station including:
an energy receiver configured to receive electromagnetic fields, said electromagnetic fields including relatively weak electromagnetic fields present in the environment and relatively stronger electromagnetic fields from a base station;
an energy converter for converting the received energy into electrical power, said energy converter comprising a field sensor for detecting the relatively weak electromagnetic fields present in the environment; and
an energy storage element for storing the electrical power;
wherein the energy converter includes:
a voltage doubler for increasing the voltage from the field sensor to a predetermined range;
a field regulator for preventing excessive voltage fluctuations from the voltage doubler; and
an accumulator for accumulating the regulated voltage, the accumulator having a diode with a high resistance reverse characteristic for ensuring one-way flow of electrical energy to the energy storage element.

### Claim 2 (depends on 1)

An environmental energy absorption system in accordance with claim 1, wherein the energy receiver further comprises a microwave receiving antenna for receiving microwave pulses and the energy converter further comprises a microwave energy converter for converting the received microwave energy into electrical power.

### Claim 3 (depends on 2)

An environmental energy absorption system in accordance with claim 2, wherein:
said base station includes:
a power supply;
a microwave energy modulation transmitter for modulating the electrical energy from the power supply into individual microwave pulses; and
a microwave transmitting antenna for transmitting the individual microwave pulses.

### Claim 4 (depends on 3)

An environmental energy absorption system in accordance with claim 3, wherein the base station further includes a wireless signal transceiver.

### Claim 5 (depends on 1)

An environmental energy absorption system in accordance with claim 1, wherein the remote station further includes a wireless signal transceiver for transmitting information generated by the field sensor.

### Claim 6 (depends on 1)

An environmental energy absorption system in accordance with claim 1, wherein the energy storage element is selected from a group consisting of a rechargeable battery and a capacitor.

### Claim 7

An environmental energy absorption method for providing power to an electronic device, comprising the steps of:
detecting relatively weak electromagnetic fields present in the environment;
receiving energy from said environment at a remote station, said energy being in the form of electromagnetic fields including relatively weak electromagnetic fields present in the environment and relatively stronger electromagnetic fields from a base station;
converting the received energy into electrical power; and
storing the electrical power;
wherein the step of converting the received energy into electrical power includes the sub-steps of:
increasing the voltage of the received energy to a predetermined range;
regulating the voltage of the received energy in order to prevent excessive voltage fluctuations; and
accumulating the regulated voltage.

### Claim 8 (depends on 7)

An environmental energy absorption method in accordance with claim 7, wherein the energy received comprises microwave pulses.

### Claim 9 (depends on 7)

An environmental energy absorption method in accordance with claim 7, further comprising, previous to the step of receiving energy from energy from the environment, the steps of:
modulating electrical energy from a power supply into individual microwave pulses; and
transmitting the individual microwave pulses.
