  • Patent number: 9391442
    Abstract: Aspects of a protection circuit and method are disclosed. A transmit circuit generates a power transmit signal for powering the transmit antenna to generate a wireless field sufficient for wirelessly charging a device. A detection circuit senses a strength of an electromagnetic field received by the transmit antenna and further configured to generate an sense signal indicating the strength of the electromagnetic field received by the transmit antenna. A power control circuit controls a switch based at least partly on the sense signal. The power control circuit can attenuate an electrical coupling between the transmit antenna and the transmit circuit such that the received electromagnetic field is inhibited from damaging the transmit antenna or the transmit circuit.

  • Patent number: 9184632
    Abstract: Exemplary embodiments are directed to wireless power transfer. A power transmitting device is attached to an existing furniture item or is embedded in a host furnishing. 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 detects a presence of a receiver device within the coupling-mode region. The presence detector may also detect a human presence. An enclosed furnishing detector detects when the furnishing item 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.
