  • Publication number: 20190199144
    Abstract: A wireless power system uses a wireless power transmitting device to transmit wireless power to wireless power receiving devices. The wireless power transmitting device has wireless power transmitting coils that extend under a wireless charging surface. Non-power-transmitting coils and magnetic sensors may be included in the wireless power transmitting device. During wireless power transfer operations, control circuitry in the wireless power transmitting device adjusts drive signals applied to the coils to reduce ambient magnetic fields. The drive signal adjustments are made based on device type information and other information on the wireless power receiving devices and/or magnetic sensor readings from the magnetic sensors. In-phase or out-of-phase drive signals are applied to minimize ambient fields depending on device type.

  • Patent number: 10256036
    Abstract: A system includes a circuit board, an inductor including windings mounted on the circuit board, and a plurality of magnetic field containment devices. Each magnetic field containment device includes an independent electrical circuit that is not directly electrically connected via a conductor to any other magnetic field containment device. Each magnetic field containment device also includes a material of a certain relative permeability. Each magnetic field containment device at least partially surrounds the inductor and, in operation, at least partially contains a magnetic B-Field generated by electrical current in the windings of the inductor. The plurality of magnetic field containment devices, in operation, enables a certain saturation current in the inductor.

  • Patent number: 10199172
    Abstract: Methods and devices related to fabrication and utilization of multilayer capacitors presenting coaxially arranged electrode layers. The capacitors may be self-shielded against electromagnetic interference with neighboring components. The capacitors may have reduced losses from fringing effects when compared to conventional capacitors. The coaxial capacitors may be two-terminal multilayer ceramic capacitors (MLCC). The design of the capacitors may facilitate an improved relationship between the electric and magnetic fields generated by the capacitor within the dielectric in some embodiments. In some embodiments, the placement of the terminals may lead to a cancelation of mutual inductances between the electrodes. Terminations that facilitate the coupling of the capacitor to a circuit board, as well as methods for fabrication of the capacitors are also discussed.

  • Patent number: 9497054
    Abstract: Electronic devices may include unshielded connectors that convey radio-frequency signals with external devices. A first electronic device may include transmitter circuitry that transmits radio-frequency signals to phase shifting circuitry. The phase shifting circuitry may pass the radio-frequency signals to a first conductive contact of a connector on the first device, may generate modified signals by applying a phase shift of approximately 180 degrees to the radio-frequency signals, and may provide the modified signals to a second conductive contact on the connector. To mitigate undesirable resonance and radiation at the connector, the connector may concurrently convey the radio-frequency signals and the modified signals to an external device over the first and second contacts while mating contacts on a connector of the external electronic device are in electrical contact with the first and second conductive contacts.
