Patents by Inventor Gerardo Jaramillo

Gerardo Jaramillo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9753013
    Abstract: A system and method comprising a charger for ionizing aerosols; a spectrometer coupled to the charger and operable to select for a predetermined particle size; a porous charge collector coupled to the spectrometer, and a MEMS electrometer. In some embodiments the charge collector may be a metal frit electrically coupled to the electrometer. The electrometer may include a comb drive actuator coupled to a moving shuttle supported on flexures.
    Type: Grant

  • Patent number: 9069031
    Abstract: A magnetic-field sensor that provides an output signal in response to an external magnetic field is described. This magnetic-field sensor includes a pair of cantilevers separated by a horizontal gap, which is displaced vertically over an open cavity by applying a time-varying voltage having a fundamental frequency across piezoelectric layers in the pair of cantilevers. The pair of cantilevers also includes magnetic-flux concentrators that convey the external magnetic field to the horizontal gap between the pair of cantilevers. A stationary magnetoresistive sensor in the horizontal gap transforms the external magnetic field into an output signal. Because the pair of cantilevers is displaced vertically at the fundamental frequency, the output signal includes a modulation signal corresponding to the external magnetic field centered around twice the fundamental frequency.
