Patents by Inventor Dawood Bhaijee

Dawood Bhaijee 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).

  • Low maintenance reference electrode for electrochemical measurements
    Patent number: 8840767
    Abstract: A low maintenance reference electrode has a liquid junction body with a multiplicity of micron-sized capillary channels extending through the body for transporting electrolyte to a test solution. A viscosity-increasing agent thickens the electrolyte to limit its flow to a rate on the order of microliters/day so that a few milliliters of electrolyte suffice to provide an extended electrode life.
    Type: Grant
    Filed: April 25, 2012
    Date of Patent: September 23, 2014
    Assignee: Thermo Fisher Scientific, Inc.
    Inventors: Xiaowen Wen, Hyoungsik Yim, Lori Hrdy, Dawood Bhaijee
  • Temperature compensation for ion-selective electrodes
    Patent number: 8287705
    Abstract: Temperature compensation for ion-selective electrodes is obtained by positioning a temperature-measuring element in a chamber of limited thermal mass which is in thermal contact with the measuring electrode filling solution but is thermally isolated from other filling solutions in the electrode. In a preferred embodiment, the temperature-measuring element comprises a thermistor enclosed within thin flexible tubing; the electrical leads of the thermistor are forced against a segment of the inner wall of the tubing by an elongated strand of material abutting the thermistor to enhance heat transfer with the thermistor.
