  • Circuits and techniques for interfacing with an electrical grid
    Patent number: 9401664
    Abstract: Circuit topologies and control methods for a multi-phase grid interface are described. In at least one embodiment, a power conversion circuit is provided that includes an inverter stage, a transformer stage, and a cycloconverter stage. The cycloconverter stage may include one cycloconverter circuit for each of multiple phases associated with a multi-phase grid. In some embodiments, each cycloconverter circuit may include first and second half-bridge circuits coupled back-to-back.

  • ENDOTRACHEAL TUBE SENSOR
    Publication number: 20110031961
    Abstract: Various devices and methods for locating an object using magnetic fields are provided. In one embodiment, a device is provided having a housing with an array of sensors that can measure a magnetic field of an object and calculate a three dimensional location of the object based upon the measured magnetic field. A display device for displaying the three dimensional location of the object can also be included. In one exemplary embodiment, an implantable device, such as an endotracheal tube, is provided having the object embedded therein. The array of sensors can be used to measure the magnetic field of the object. The device can then calculate the three dimensional location of the object and the display device can display the calculated location of the object embedded in the implantable device.
