John Anthony Tillotson 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).

  • Oxygen sensors
    Patent number: 8845871
    Abstract: An electrochemical oxygen sensor includes a micro-porous plastic membrane supported on a sealing disk and located between a gas inflow port and the sensor's electrolyte. The membrane and disk minimize thermal shock effects due to using the sensor at a first location, at a first temperature, and then moving it to a second location at a different temperature.
    Type: Grant
    Filed: June 21, 2012
    Date of Patent: September 30, 2014
    Assignee: Honeywell International Inc.
    Inventors: John Chapples, John Anthony Tillotson, Ian McLeod, Martin Williamson

  • Electrochemical Oxygen Sensor with Internal Barrier to Oxygen Diffusion
    Publication number: 20120193229
    Abstract: An electrochemical sensor includes a micro-porous plastic membrane supported on a disk and located between a gas inflow port and an electrolyte having a gelled oxygen diffusion barrier. The oxygen diffusion barrier, formed of gelled agar, minimizes thermal shock effects by impregnating any porous materials in the sensor.
