  • Patent number: 10186949
    Abstract: A DC-to-DC power converter device has a common magnetic core structure that serves the functions of both transformer device and output inductor by integrating each into the common core. The transformer device has primary and secondary windings integrated into a first leg structure of the magnetic core, and the output inductor device has an output inductor winding integrated into a second leg structure of the magnetic core, the inductor winding structure for delivering output current to a load when a periodically switched input voltage is applied across the primary winding structure. The winding polarities of the transformer secondary winding structure and of the output inductor winding structure provide oppositely oriented polarities of electromotive force (EMF) to substantially reduce an output current ripple to an output load when delivering power through the transformer, through the output inductor and into the output load.

  • Patent number: 10175272
    Abstract: A remote differential voltage sensing circuit having a voltage input (Vin) and a voltage output (Vout), comprises a dual differential input stage including a common-source or common-collector differential input stage in parallel with a common-gate or common-base differential input stage. The common-source or collector differential input stage has differential inputs, one coupled to the voltage input (Vin) and the other coupled to the voltage output (Vout). The common-gate or common-base differential input stage has differential inputs, one coupled to a local ground (Agnd) and the other coupled to a remote ground (Rgnd). An output stage is driven by an output of the dual differential input stage and produces an output voltage at the voltage output (Vout). A compensation network is coupled between the voltage output (Vout) and the output of the dual differential input stage.

  • Publication number: 20180356483
    Abstract: A passive apparatus including a plurality of resonators increases signal-to-noise ratio of radiofrequency signals emitted by a specimen and captured by an MRI machine. The apparatus increases the magnetic field component of radiofrequency energy during signal transmission from the MRI machine to the specimen, and/or reception of signals from the specimen to the MRI machine. Moreover, the apparatus enhances specimen safety by substantially avoiding unwanted generation of an electric field, or an increase in the electric field component of the RF energy.
