Patent number: 10199172Abstract: 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.Type: GrantFiled: September 24, 2016Date of Patent: February 5, 2019Assignee: Apple Inc.Inventors: Paul A.

Publication number: 20130091939Abstract: Methods and systems for measuring erosion. Systems of various embodiments include a sensor adapted to be placed where earthen material is expected to move and to sense a condition related to that movement (for instance, the position of the sensor). The sensor includes a receiver for receiving a wireless signal (be it acoustic, magneto-inductive, etc.) from another sensor which conveys an identifier for the second sensor. The first sensor also includes a signal generator that generates a second (possibly wireless) signal conveying that identifier and its own identifier. Systems of some embodiments include a second receiver placed outside of the region. If desired, the sensor can determine the signal strengths of the signals that they receive from the other sensor and can convey an indication of the received signal strengths. Furthermore, some sensors include accelerometers, roll sensors, tilt sensors, yaw sensors, magnetometers, etc.Type: ApplicationFiled: December 4, 2012Publication date: April 18, 2013Inventors: Genda Chen, David Pommerenke, Zhi Zhou, Ying Huang, Andro Radchenko
