Latest Patents

One of his latest inventions is a detector designed for use as a fire detector. This detector features two channels that allow for the discrimination between energy received from a fire and a "false fire." False alarms can occur due to radiation from cold black body sources flickering at specific frequencies. Basham's invention addresses this issue by incorporating a notch filter that, in combination with another filter, ensures that radiation detected around 4.3 microns is transmitted to a sensor. A processor then compares the received value with a computed value from two other channels. If a threshold value is exceeded, an alarm is triggered, effectively reducing false alarms from prior art systems.

Another significant patent involves apparatus for detecting the presence of a fire. This system includes a pair of detectors for radiation characteristic of a fire, such as at 4.3 microns, and an additional detector for black body radiation at 3.8 microns. Filters are used to select the output components at flame flicker frequencies. The outputs from the detector pair are cross-correlated to produce a relatively noise-free signal. This signal is then divided by a factor obtained from 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 a more accurate detection of fire presence.
