A system for cleaning a particulate trap comprises locating the trap in a chamber and forcing cleaning air through the trap. The air and removed particulates is extracted from the trap towards a filter. The expelled air essentially without the removed particulates from the chamber, the removed particulates being essentially trapped in the filter. The trap is locatable about a longitudinal axis such that air is urged in a longitudinal direction through the trap. The trap is supportable on at least one rotatable roller to affect rotation about the axis. A motor and blower draws air from the chamber and an air pressure differential about the filter causes the particulate to be directed through the filter and excess air is pumped out of the blower by the motor operating the blower.

An infrared energy detection apparatus having a first array of infrared detectors adapted to detect infrared energy of a first wavelength and produce an electrical signal corresponding to such detected energy, and a second array of infrared detectors, positioned to intercept infrared energy passing through the first array, and adapted to detect energy of a second wavelength in such intercepted energy and produce an electrical signal corresponding to such detected energy. The first array of infrared detectors includes an array of detector devices formed along a lower portion thereof adapted to detect a portion of radiation impinging on the upper portion thereof and, electronic circuitry disposed between the upper and lower portions and connected to the detector devices for producing electrical signals representative of the detected energy having the first wavelength. The second array of infrared detectors includes an array of detector devices adapted to detect a portion of radiation passed through the first array of detectors and impinging on the second array and having the second wavelength and, electronic circuitry for producing electrical signals representative of the detected energy having the second wavelength. The first array of infrared detectors has formed therein an array of lenses to direct infrared energy impinging on the upper surface to the detector devices formed in the first array.
