Abstract
The present disclosure provides a method for improving battery life of electronic devices such as Bluetooth headsets, smart-watches among others running on small batteries, for example coin batteries. The method may include wireless power transmission through suitable techniques such as pocket-forming, while including receivers and capacitors in the aforementioned devices. Wirelessly charged capacitors may provide sufficient power on which devices may run, and thus, battery life of such electronic devices may be enhanced.
Claims20
A method for wireless power transmission to improve battery life in a portable electronic device, comprising:
- transmitting pockets of energy consisting of RF waves from a transmitter with at least two RF antennas and a transmitter communication device;
- receiving the pockets of energy through a RF antenna in a receiver with a receiver communication device and a controller connected to the portable electronic device;
- and
- converting the pockets of energy for charging an auxiliary power supply of the electronic device responsive to communication signals between the transmitter and receiver communication devices related to the power requirements of the portable electronic device.
A system for wireless power transmission to improve battery life in a portable electronic device, comprising:
- a transmitter having at least two RF antennas in an array for generating pockets of energy;
- a receiver with an RF antenna embedded in a portable electronic device for receiving the pockets of energy and for converting the pockets of energy into a constant DC voltage;
- an auxiliary power supply for storing the constant DC voltage to fully or partially power the portable electronic device.
A system for wireless power transmission to improve battery life in a portable electronic device, comprising:
- a transmitter for generating RF waves having at least two RF antennas to transmit the generated RF waves through the antennas in constructive interference patterns;
- a micro-controller within the transmitter controlling the constructive interference patterns of generated RF waves to form pockets of energy in predetermined areas or regions in space;
- a receiver embedded within the portable electronic device with at least one antenna to receive the pockets of energy in the predetermined regions in space;
- a micro-controller within the receiver for communicating the power requirements of the portable electronic device to the micro-controller in the transmitter;
- and
- an auxiliary power supply within the receiver having a parallel connection to a main power supply in the portable electronic device wherein the auxiliary power supply is charged by the pockets of energy.
A receiver for wireless power transmission to a portable electronic device, comprising:
- an antenna for sending and receiving RF signals;
- a rectifier connected to the antenna for rectifying alternating current from the RF waves received by the antenna to provide direct current;
- a power converter connected to the rectifier for regulating the DC voltage for charging an auxiliary power supply or a battery associated with the portable electronic device;
- a communication device for generating a communication RF signal identifying the auxiliary power supply and battery level of the electronic device;
- and
- a micro-controller connected to the communication device and to the auxiliary and the battery power supplies to regulate predefined intervals of the auxiliary power supply or battery powering the portable electronic device.
