A system and method for bi-directional communication through capacitive coupling is achieved with capacitive plates within the environment of a wireless power transfer system. Data is transferred using capacitance over a separate path from the transfer of electrical power in the wireless power transfer system.

Bi-directional communication through capacitive coupling in wireless devices

A wireless power transfer (WPT) system is operative to dynamically make power-transfer efficiency optimizations based on supply power, load characteristics, or a combination thereof. In various embodiments, optimizations include power-level-specific path selection, loading-based WPT voltage adjustments, and other techniques in various combinations.

Apparatus for dynamic control of wireless power transfer

A base station comprising: a wireless power receiver module to wirelessly receive energy from a portable device; a wireless transceiver module adapted to establish a wireless data communication with the portable device so as to wirelessly receive/transmit data; a wired interface for wired connection to an accessory device; a power distribution module coupled to the wireless power receiver module and adapted to supply the energy received from the portable device both to the accessory device, via the wired interface, and to the wireless transceiver module; a communication module coupled to the wireless transceiver module and to the wired interface, adapted to adapt data wirelessly received from the portable device, via the wireless transceiver module, into data suitable to be transmitted in a wired way to the accessory device, via the wired interface, and vice versa, to adapt data received in a wired way from the accessory device, via the wired interface, into data suitable to be transmitted wirelessly to the portable device, via the wireless transceiver module; wherein the base station is passive, devoid of any internal power source.

Base station

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.

Wireless power system and method with protection from overvoltage conditions

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.

Wireless power system with protection from overvoltage conditions

A reader includes a scanning head that comprises an optical sensor to capture an indicia that encodes data and a processor to interpret the indicia to decode the data, and an elongate handle connected at a first end to the scanning head and graspable to orient the optical sensor toward the indicia. A selected one of the scanning head and the elongate handle includes: a first receiving coil; a second receiving coil; a battery to provide electric power to the processor and the optical sensor; and a power receiving circuit coupled to the first and second receiving coils in series, and configured to operate the first and second receiving coils together to wirelessly receive electric power to charge the battery.

Coded image capture system of components and power provisioning therefor

Systems and methods which allow for the coexistence of wireless charging (WCH) and short-range communication (e.g., NFC) in a close spaced relationship. A cradle may include a plurality of slots which each removably receive one of the mobile systems. The cradle and the mobile systems may each include NFC and WCH coils that are closely spaced but are placed orthogonally relative to each other. A time multiplexer may be used to disconnect WCH while performing NFC communication to prevent crosstalk in the same mobile system. A filtering system may act on the NFC circuits to allow contemporary activation of WCH and NFC communication on mobile systems. A slot multiplexer may be provided in the cradle to allow for selection of a single mobile system slot at a time to activate NFC communication with the mobile systems, using a single NFC communication controller for all of the mobile system slots.

Coexistence of wireless charging and near field communication in a portable data terminal

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.

Near field communication channel initiation via wireless charging channel

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.
