Abstract

The present invention describes means to intentionally transmit power wirelessly from a portable communication device like a mobile phone, smart-phone, tablet or telephone watch using radio frequency, ultrasound, microwave or laser technologies to power up or charge devices external to the portable communication device. In particular the wireless power transmitter is physically placed inside the portable communication device or coupled to it, in order to have a means to transfer power without wires or cables to other devices. The present invention may be utilized in applications like sensors, implanted devices for medical use, speakers, mouse, keyboard, electrical glasses for 3D viewing, small displays, gadgets in the car, electronic toys and so on.

Claims

1. A portable communication device comprising a transmitter of wireless power,

wherein said transmitter of wireless power is embedded in said portable communication device;

wherein said transmitter of wireless power is used to transmit wireless power and comprises a controller to control the operation of said transmitter of wireless power;

wherein at least a portion of said transmitted wireless power is received by at least one wireless power receiver;

wherein a second dedicated device is comprising said at least one wireless power receiver;

wherein said second dedicated device is external to said portable communication device;

wherein at least a portion of a wireless power received by said at least one wireless power receiver is utilized to store energy or to power up at least a section of said second dedicated device,

wherein said transmitter of wireless power is selected from the group consisting of ultrasound, and optical power transmitter, and

wherein said portable communication device belongs to the group of devices including cellular telephone devices, tablet devices, portable radio devices and telephone watch devices.

2. The portable communication device of claim 1, wherein said controller of said transmitter of wireless power is managed by executing a software program, and

wherein said software program runs on a processing apparatus of said portable communication device.

3. The portable communication device of claim 1, wherein said transmitter of wireless power is transmitting wireless power simultaneously with transmission and reception of data to and from said second dedicated device, to and from a Wi Fi device or a cellular base station.

4. The portable communication device of claim 1, wherein said transmitter of wireless power operates at a frequency, and

wherein said frequency is adaptively tuned to optimize the transfer of said wireless power to said at least one wireless power receiver.

5. The portable communication device of claim 1, further coupled to an external energy storing device.

6. The portable communication device of claim 1, wherein said second dedicated device belongs to the group of devices including electric glasses, 3D glasses, smart glasses and small displays devices.

7. The portable communication device of claim 1, wherein said transmitter of wireless power is an ultrasound power transmitter, and said second dedicated device is an implanted medical device.

8. The portable communication device of claim 1, wherein said second dedicated device is a sensor device.

9. A method for transmitting wireless power comprising:

placing a wireless power transmitter in a portable communication device;

wherein said wireless power transmitter comprises a controller to control the operation of said wireless power transmitter;

transmitting wireless power with said wireless power transmitter;

receiving at least a portion of said transmitted wireless power in at least one wireless power receiver;

wherein a second dedicated device is comprising said at least one wireless power receiver;

wherein said second dedicated device is external to said portable communication device;

wherein at least a portion of wireless power received by said at least one wireless power receiver is utilized to store energy or to power up at least a section of said second dedicated device,

wherein said wireless power transmitter is selected from the group consisting of ultrasound, and optical power transmitter, and

wherein said portable communication device belongs to the group of devices including cellular telephone devices, tablet devices, portable radio devices and telephone watch devices.
