SYSTEMS AND METHODS FOR EXTENDING THE POWER CAPABILITY OF A WIRELESS CHARGER
First Claim
1. An apparatus for transferring energy wirelessly to at least one receive antenna of at least one receiver, the apparatus comprising:
- a first transmit antenna configured to generate a first wireless field when the at least one receiver is in an energy transfer region of the first transmit antenna;
a second transmit antenna spatially separated from the first transmit antenna, the second transmit antenna configured to generate a second wireless field when the at least one receiver is in an energy transfer region of the second transmit antenna; and
a controller operationally coupled to the first transmit antenna and the second transmit antenna and configured to activate at least one of the first transmit antenna or the second transmit antenna based on whether the at least one receiver is in an energy transfer region of one or both of the first wireless field and the second wireless field, the controller further configured to control, when both the first transmit antenna and the second transmit antenna are activated, whether the first transmit antenna and the second transmit antenna independently transfer energy wirelessly to a same receiver via the first and second wireless fields, whether the first transmit antenna and the second transmit antenna jointly transfer energy wirelessly to the same receiver via the first and second wireless fields, or whether the first transmit antenna and the second transmit antenna transfer energy wirelessly to different receivers via the first and second wirelessly fields.

Abstract
This disclosure provides systems, methods and apparatus for wireless power transfer. In one aspect, an apparatus transfers energy wirelessly to at least one receive antenna of at least one receiver. The apparatus comprises a first antenna configured to generate a first wireless field when the at least one receiver is in an energy transfer region of the first transmit antenna. The apparatus further comprises a second antenna configured to generate a second wireless field when the at least one receiver is in an energy transfer region of the second transmit antenna. The apparatus further comprises a controller configured to activate at least one of the first antenna or the second antenna based on whether the at least one receiver is in an energy transfer region of one or both of the first and second wireless fields.

7. A method of transferring energy wirelessly to at least one receive antenna of at least one receiver, the method comprising:
-
generating, by a first transmit antenna, a first wireless field when the at least one receiver is in an energy transfer region of the first transmit antenna; generating, by a second transmit antenna spatially separated from the first transmit antenna, a second wireless field when the at least one receiver is in an energy transfer region of the second transmit antenna; activating at least one of the first transmit antenna or the second transmit antenna based on whether the at least one receiver is in an energy transfer region of one or both of the first wireless field and the second wireless field; and controlling, when both the first transmit antenna and the second transmit antenna are activated, whether the first transmit antenna and the second transmit antenna independently transfer energy wirelessly to a same receiver via the first and second wireless fields, whether the first transmit antenna and the second transmit antenna jointly transfer energy wirelessly to the same receiver via the first and second wireless fields, or whether the first transmit antenna and the second transmit antenna transfer energy wirelessly to different receivers via the first and second wirelessly fields. - View Dependent Claims (8, 9, 10, 11, 12)

13. An apparatus for transferring energy wirelessly to at least one receive antenna of at least one receiver, the apparatus comprising:
-
means for generating a first wireless field when the at least one receiver is in an energy transfer region of the means for generating the first wireless field; means for generating a second wireless field when the at least one receiver is in an energy transfer region of the means for generating the second wireless field; means for activating at least one of the means for generating the first wireless field or the means for generating the second wireless field based on whether the at least one receiver is in an energy transfer region of one or both of the first wireless field and the second wireless field; and means for controlling, when both the means for generating the first wireless field and the means for generating the second wireless field are activated, whether the means for generating the first wireless field and the means for generating the second wireless field independently transfer energy wirelessly to a same receiver via the first and second wireless fields, whether the means for generating the first wireless field and the means for generating the second wireless field jointly transfer energy wirelessly to the same receiver via the first and second wireless fields, or whether the means for generating the first wireless field and the means for generating the second wireless field transfer energy wirelessly to different receivers via the first and second wirelessly fields. - View Dependent Claims (14, 15, 16, 17, 18, 19)
