摘要： A wireless power system providing protection from overvoltage conditions. A wireless power receiver has one or more magnets to allow detection of a distance of the wireless power receiver from a wireless power transmitter using a Hall effect sensor. When the detected distance is less than a determined threshold, the wireless power transmitter is instructed to transmit power. The wireless power receiver has one or more transient voltage suppression (TVS) diodes communicatively connected so that when a determined operating voltage of a protected portion of the receiver is exceeded, the TVS diodes provide a low impedance path for transient current to divert the transient current away from the protected portion of the receiver. When the wireless power receiver detects an overvoltage condition, the receiver sends a reset command to the wireless power transmitter.

摘要： A mounting assembly and method that utilize Hall effect sensors to detect orientation and insertion of a portable device in a base are provided. Hall effect sensors positioned on one of a portable device and a base are arranged to interact with one or more magnets positioned on the other of the portable device or the base such that a change in proximity of at least one of the magnets to at least one of the sensors will cause the sensor to output a voltage signal that differs depending on the nearness of the magnet. Depending on at least one of the magnitude of the signal, the profile of the signal over time, and the identity of the sensor that output the signal, it is determined whether the orientation of the portable device in the base is correct and/or if the portable device is fully inserted in the base.

摘要： Systems and methods which utilize wireless charging to initiate near field communication (NFC) pairing between mobile systems which utilize wireless charging and wireless charging base stations. Wireless signals sent by a mobile system over a wireless charging channel are used to initiate communication between an NFC reader presented in a base station and a passive NFC tag (or an active NFC tag used in a passive mode) present in the mobile system. Such feature allows the mobile system to act as an initiator for NFC communication without requiring the mobile system to be equipped with an NFC reader. A wireless power receiver of a mobile system may communicate with a wireless power transmitter of a base station using backscatter modulation. Commands of a standard wireless charging protocol may be repurposed to send a request for initiation of an NFC session from a mobile system to a base station.

摘要： A wireless power system and method performs wireless power transmission with sensing to detect a distance and/or misalignment of a power receiver from the power transmitter. Power transmission is adjusted in response to the sensing detecting the distance and/or misalignment exceeding a determined threshold, or in response to instructions sent by the receiver based, at least in part, on a duration of the overvoltage condition exceeding a determined time period.
