WIRELESS POWER TRANSFER FOR VEHICLES
First Claim
1. An apparatus, comprising:
- a power transmitting device for use on a vehicle element comprising;
a transmit antenna to wirelessly transfer power to a receive antenna by generating a near-field radiation at a resonant frequency within a coupling-mode region; and
an amplifier for applying a driving signal to the transmit antenna at the resonant frequency.

Abstract
Exemplary embodiments are directed to wireless power transfer. A power transmitting device is attached to an existing vehicle item or is embedded in a vehicle element. The power transmitting device includes a transmit antenna to wirelessly transfer power to a receive antenna by generating a near-field radiation within a coupling-mode region. An amplifier applies a driving signal to the transmit antenna. A presence detector may detect a presence of a receiver device within the coupling-mode region. The presence detector may also detect a human presence. An enclosed compartment detector may detect when the vehicle element is in a closed state. A power output may be adjusted in response to the closed state, the presence of a receiver device, and the presence of a human.
