Claims26
A power transmission apparatus comprising:
- a power transmitting unit which includes (1) an induction unit which receives an electrical energy from an external power source by induction and (2) a magnetic resonance unit which transmits the electrical energy to an external receiving unit by magnetic resonance.
A power receiving apparatus comprising:
- a power receiving unit which includes (1) a magnetic resonance unit that receives an electrical energy from an external source by magnetic resonance and (2) an induction unit which transmits the electrical energy to an external reception unit by induction.
A power transmission system comprising:
- a power transmitting unit which includes (1) an induction unit which receives an electrical energy from an external power source by induction and (2) a magnetic resonance transmitting unit which transmits the electrical energy by magnetic resonance;
- a power receiving unit which includes (1) a magnetic resonance receiving unit that receives the electrical energy from the power transmission unit by magnetic resonance and (2) an induction unit which transmits the electrical energy to an external reception unit by induction.
An electronic apparatus, comprising:
- a reception coil in the electronic apparatus in inductive communication with a magnetic resonance receiving unit via an electromagnetic field,
- wherein,
