Latest Patents

Mark E Pleydell holds a patent for an apparatus that detects the presence of a fire. This invention includes a pair of detectors that identify radiation characteristic of a fire, specifically at 4.3 microns, along with an additional detector for radiation typical of a black body at 3.8 microns. The apparatus utilizes filters to select the output components at flame flicker frequencies. The filtered outputs from the detector pair are then cross-correlated to generate a relatively noise-free signal. This signal is divided by a factor obtained by cross-correlating the further detector's filtered output with the average of the detector pair's filtered outputs. The result is applied to a threshold-responsive circuit, allowing for effective detection of fire based on the degree of similarity between the output signals.
