摘要： A power circuit for use with a resistive thermal radiation source in which the power delivered to the resistive thermal radiation source will remain constant within a preselected deviation over a fixed period of time as the source resistance of the source varies between an initial source resistance and a second source resistance at the operating temperature. The power circuit is designed to maintain constant power within a preselected deviation by using the resistance of the resistive thermal radiation source to calculate a preselected resistance used in the power circuit according to the following equation: ##EQU1## wherein .DELTA.P=P.sub.si -P.sub.s ; P.sub.si =the initial power on the resistive thermal radiation source; P.sub.s =the power on the resistive thermal radiation source when the source resistance is equal to the second source resistance; K.sub.1 =RO/R.sub.si ; R0=the preselected resistance; R.sub.si =the initial source resistance; K.sub.2 =R.sub.s /R.sub.si ; and R.sub.s =the second source resistance.

摘要： A method for compensating for baseline or span drift in gas sensing equipment includes obtaining gas concentration data over a time period and identifying a quiescent period within that time period. The method compares a component concentration corresponding to the quiescent period with one or more additional component concentrations relating to different quiescent periods and calculates an estimated background gas concentration for a predetermined number of time periods. The estimated background concentration is then compared to a preset, or expected, background concentration, and a correction value is calculated. For baseline drift, a correction value is determined to be the difference between the estimated background concentration and the present (expected) background concentration. For span drift, a correction value is determined to be the ratio of the estimated background concentration to the preset (expect) background concentration. Measured concentrations by the gas sensor are then adjusted by the correction value.

摘要： A diffusion-type NDIR gas analyzer with an improved response time due to convection flow created by a temperature gradient between gas located within a waveguide and gas located within a diffusion pocket of space created between the waveguide and a semi-permeable membrane which surrounds the waveguide. The temperature gradient may be created by a thermally resistive radiation source that is not thermally isolated from the waveguide. The semi-permeable membrane is made of a hydrophobic material and has a thickness sufficient to provide its own structural integrity. The semi-permeable membrane can have a porosity less than approximately 50 microns and be comprised of ultra high molecular weight polyethylene or Teflon®.

摘要： An improved self-cleaning oven (10) is provided having an assembly (12) to control the cleaning cycle time of the oven (10) depending upon the degree of oven contamination and soil present therein. The assembly (12) includes a measuring chamber (16) as well as a passageway (18) communicating the interior (14) of the oven (10) and the chamber (16). A smoke detector (32) (preferably an infrared smoke detector) is associated with the chamber (16) and is coupled with a controller (20) so as to measure a parameter of smoke passing through the chamber during at least a portion of the cleaning cycle. This parameter is then used to determine the proper duration of the cleaning cycle. In preferred forms, measuring chamber (16a) is equipped with an ambient air inlet (52) and outlet (54) so as to draw an ambient air stream through the chamber (16a) between the smoke detector (32) and the oven gas stream.
