The catalyst is capable of adsorbing carbon monoxide. The sensing element can also include a heater and a temperature sensor. A flow sensor is provided for sensing a flow rate of gas directed at the sensing element. The signal processing module is coupled to the flow sensor and the temperature sensor. A flow sensor sends signals indicative of the flow rate to the processing module while the temperature sensor sends signals indicative of the temperature of the sensing element to the processing module. After carbon monoxide has been adsorbed onto the catalyst and metal oxide layer for a fixed time period, the heater is activated to heat the sensing element above the light-off temperature or at least as high as the oxidation temperature of the adsorbed carbon monoxide.

The signal differential is compared to a selected value and sensor output is enabled or disabled. High noise immunity, resistance to target reflection, and output reliability result.

Abstract: A detector, such as a photodetector, is provided with a serial output and serial input capability so that a first plurality of pulses can be transmitted from the detector in a first preselected direction. The first plurality of pulses represent a coded pattern. When pulses are received by the receiver portion of the detector, the received second plurality of pulses is compared to the first plurality of pulses to determine whether or not the two pluralities of pulses represent precisely matched coded patterns. The use of coded patterns that comprise a plurality of bits, or pulses, significantly decreases the chance of a mis-identification of a received pulse as being representative of a reflected transmitted pulse.

Abstract: A photodetector is provided with two light sources and a light sensitive component. The use of two light sources significantly reduces the opportunity of a surface feature, or abnormality, from focusing light back toward the light sensitive component in a manner that could possible cause the photodetector to misinterpret the intensified light as being indicative of the absence of an object in the detection zone. The light sources and light sensitive component can be arranged along an axis which is either parallel to the path of the objects to be detected or perpendicular to their path.
