Biological effects of magnetic power transfer

Abstract

Described herein are embodiments of forming a wireless power transfer system which uses at least two high-Q magnetically resonant elements, and which have values which are set to acceptable levels of electric and magnetic field strength and radiated power.

1 . A method, comprising:
 forming a wireless power transfer system which uses at least two high-Q magnetically resonant elements, and   which have values which are set to acceptable levels of electric and magnetic field strength and radiated power.   
     
     
         2 . A method as in  claim 1 , wherein said acceptable levels comprise accepted standards for human safety. 
     
     
         3 . A method as in  claim 1 , wherein said acceptable levels comprise accepted standards for interference. 
     
     
         4 . A method as in  claim 1 , wherein said acceptable levels comprise accepted standards for both human safety and interference. 
     
     
         5 . A method as in  claim 1 , wherein said wireless power transfer is carried out at 13.56 MHz +/−7 kHz. 
     
     
         6 . A method as in  claim 1 , wherein said wireless transfer is carried out at 135 kHz. 
     
     
         7 . A method as in  claim 1 , wherein said wireless power transfer system creates fields that are higher than fields allowed by the standards, but are only higher than those standards in areas where a person cannot be located. 
     
     
         8 . A method as in  claim 1 , wherein said wireless power transfer system creates fields that are based both on biological effects and interference effects with other electronic devices. 
     
     
         9 . A wireless power transfer system for transferring power to a high-Q receiver, comprising:
 a high-Q transmitter which creates electric and magnetic field and radiated power levels that comply with acceptable levels in the region of operation.   
     
     
         10 . A system as in  claim 9 , wherein said acceptable levels for said transmitter are compliant with standards for human safety. 
     
     
         11 . A system as in  claim 9 , wherein said levels are compliant with accepted standards for interference. 
     
     
         12 . A system as in  claim 9 , wherein said levels are compliant with standards for both human safety and interference. 
     
     
         13 . A system as in  claim 9 , wherein said wireless power transfer is carried out at 13.56 MHz +/−7 kHz. 
     
     
         14 . A system as in  claim 9 , wherein said wireless power transfer is carried out at 135 kHz. 
     
     
         15 . A system as in  claim 9 , wherein said transmitter creates a level that is higher than the level of the standard, but is only in an area where a user cannot be located. 
     
     
         16 . A system as in  claim 9 , wherein said standards are standards both for biological effects, and also for interference effects. 
     
     
         17 . A method as in  claim 1 , wherein said standards are set by standard setting agencies. 
     
     
         18 . A method as in  claim 1 , wherein said standards are recommendations set by committees. 
     
     
         19 . A method as in  claim 1 , wherein said standards comprise both human safety and interference regulations and recommendations. 
     
     
         20 . A system as in  claim 9 , wherein said standards are set by standard setting agencies. 
     
     
         21 . A system as in  claim 9 , wherein said standards are recommendations set by committees. 
     
     
         22 . A system as in  claim 9 , wherein said standards comprise both human safety and interference regulations and recommendations.
