Filed:

Aug 10, 2017

Appl. No.:

15/673530

Inventors:

- Watertown MA, US
Morris P. Kesler - Bedford MA, US
Katherine L. Hall - Arlington MA, US
Ron Fiorello - Tewksbury MA, US
Matthew J. MacDonald - Boxford MA, US

International Classification:

H02J 50/12
H02J 50/80
H01F 27/22
H03H 7/40
H02J 7/02
H02J 50/50
H01F 38/14

Abstract:

Described herein are improved configurations for a wireless power transfer. Described are methods and designs to reduce and manage heating and heat dissipation in resonator structures. Configuration and orientation of magnetic material as well as heat sinking material with respect to the dipole moment of the resonator is used to reduce and control thermal properties of the resonator structure and reduce the effects of heating on the performance of wireless power transfer.

Inventors:

- Watertown MA, US
Herbert Toby Lou - Carlisle MA, US
Christopher Buenrostro - Lexington MA, US

International Classification:

H04B 5/00
H02J 5/00
H02J 7/02
H01F 38/14

US Classification:

307104

Abstract:

Improved configurations for wireless energy transfer can include system elements of a wireless energy transfer system that may pair in-band and out-of-band communication channels by exchanging related information. Energy transfer signals may be modulated according to defined waveforms. Information about the signal may be transmitted using an out-of-band communication channel. A system element that receives both the signal and information may verify that they correspond to the same system element.

International Classification:

H01F 27/02
H01F 38/14

US Classification:

307104

Abstract:

Described herein are improved configurations for a wireless power transfer and mechanical enclosures. The described structure holds and secures the components of a resonator while providing adequate structural integrity, thermal control, and protection against environmental elements. The coil enclosure structure comprises a flat, planar material with a recess for an electrical conductor wrapped around blocks of magnetic material as well as an additional planar material to act as a cover for the recess.

International Classification:

H01F 38/14

US Classification:

307104

Abstract:

Methods and systems for wireless transmission of power to a battery-operated device include a power receiving apparatus featuring at least one receiving resonator and a housing dimensioned to engage with a battery compartment of a battery-operated device, and a power transmitting apparatus including: a first pair of spaced source resonators, where each source resonator in the first pair features a loop of conducting material surrounding a common first axis; a second pair of spaced source resonators, where each source resonator in the second pair features a loop of conducting material surrounding a common second axis different from the first axis; and a controller coupled to the first and second pairs of source resonators and configured to provide non-radiative wireless power transfer from the power transmitting apparatus to the power receiving apparatus by alternately activating the first and second pairs of source resonators.
