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.

Abstract: Spring clips that provide a reliable, low-impedance, low-harmonic path between various conductive enclosure components of electronic devices. These spring clips can include a low-impedance connection on each of two ends, where each end physically and electrically connects to an enclosure component of an electronic device. This can reduce an impedance between enclosure components and reduce the amplitude and harmonics of signals coupled onto them from a nearby antenna or other waveguide.

Abstract: An apparatus (100) for real-time detection of fraudulent digital transactions is disclosed. The apparatus comprises: a transceiver module arranged to receive information data of a digital transaction; a model generator module (102) arranged to dynamically generate a predictive model for fraud detection based collectively on historical information data relating to identified fraudulent transactions and the received information data; and a fraud detection module (104) having a plurality of anomaly detection modules (1042, 1044, 1046) arranged to respectively process the received information data differently to generate a plurality of scores, which are aggregated to provide an aggregated score to enable real-time determination of whether the digital transaction is a fraudulent digital transaction. A first anomaly detection module (1042) is configured to process the received information data using the predictive model to generate a first score. A related method is disclosed too.

Abstract: Systems and methods we provided to identify payment data and desensitize the data by a secure card reader. Desensitization of the payment data may include replacing sensitive information such as discretionary data with zeroes or other predetermined values. Desensitization may also include replacing sensitive information with fraud detection data such as merchant identifying information. Desensitization of the payment data may leave certain payment data intact for customer tracking or other non-payment related purposes.

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.
