US Patent:

6467334, Oct 22, 2002
Filed:

May 11, 2001
Appl. No.:

09/854056
Inventors:

Greg A. Lloyd - Spokane WA
William A. Fuglevand - Spokane WA
Assignee:

Avista Laboratories, Inc. - Spokane WA
International Classification:

G01N 2712
US Classification:

73 3106
Abstract:

A method of speeding startup of a MOS gas sensor having a sensor element for sensing a target gas, and a heater configured to heat the sensor element, and which is responsive to a voltage applied thereto. The heater has an operating temperature which is selectively maintained by applying a first voltage thereto, and the heater further has a maximum recommended temperature which is selectively maintained by applying a second voltage thereto. The maximum recommended temperature is higher than the operating temperature, and the second voltage is higher than the first voltage. The method includes providing a third voltage to the heater which is greater than the second voltage for a predetermined amount of time which is selected to increase the temperature to a level not greater than the maximum recommended temperature in a shorter time period than if the second voltage is applied and maintained. A MOS gas sensor system and a fuel cell system also employ such a method.
