Abstract: Multilayer ceramic capacitor structures may include structural arrangements, materials, and/or substrate modifications that can improve the reliability of the capacitor for long-term usage when faced with environmental stress. Embodiments may implement reduced entryways in the termination patterns of the capacitor to decrease damage potential due to exposure of moisture. Embodiments may implement structures that decrease interfaces with different physical characteristics, which may lead to a reduction in the formation of micro-fractures during regular usage. Methods of manufacture for the features that improve reliability are also detailed.

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.

Abstract: A wireless power system may use a wireless power transmitting device to transmit wireless power to a wireless power receiving device. The wireless power transmitting device may have microwave antennas that extend along an axis in a staggered arrangement. In the staggered arrangement, the microwave antennas are positioned on alternating sides of the axis. Each microwave antenna is elongated along a dimension that is perpendicular to the axis. Multiple antennas may overlap a wireless power receiving antenna in the wireless power receiving device. Control circuitry may use oscillator and amplifier circuitry to provide antennas that have been overlapped by the wireless power receiving antenna with drive signals. The drive signals may be adjusted based on feedback from the wireless power receiving device to enhance power transmission efficiency. The system may have a wireless power transmitting device with inductive wireless power transmitting coils.
