Abstract: There are described systems for improving the sensitivity, usability, and robustness of particle detection systems (100) adapted to detect particles directly in a volume (110) being monitored, the system (100) including at least one illumination means (102) for directing a beam (106) of radiation through at least part of the air volume being monitored (110), an image sensor (104) is positioned to capture images of a least part of a beam (106) from an illumination means (102); and means to analyse (107) the captured images to detect the presence of particles within the volume on the basis of radiation captured in the images.

Abstract: A filter arrangement for removing impurities from a fluid is disclosed, the filter arrangement (10) includes a plurality of screen portions (18, 20) through which the fluid passes. The screen portions include a first screen portion (18) and a second screen portion (20) separated by a predetermined distance. The predetermined distance can be determined on the basis of a threshold particle length. In one form the filter arrangement (10) is mounted in a housing (16) which is configured to receive two filter elements (18, 20) arranged in a nested configuration. A particle detector using the filter is described.

Abstract: A PARTICLE DETECTOR (10) INCLUDING A CHAMBER (12), A FIRST ASPIRATOR (14), A SENSOR(S) (28), A CONTROLLER (20) AND CLEAN AIR SUPPLY (18). THE CONTROLLER, WHEN IN A DETECTING MODE, RECEIVES AN INDICATIVE SIGNAL FROM THE SENSOR AND APPLIES LOGIC TO THE INDICATIVE SIGNAL TO GENERATE A FURTHER SIGNAL (22), AND WHEN IN THE PURGE MODE CONTROLS SUBSTANTIAL PURGING OF THE CHAMBER OF SAMPLE FLUID WITH CLEAN FLUID FROM THE CLEAN FLUID SUPPLY. THE CONTROLLER RECEIVES THE INDICATIVE SIGNAL WHEN THE CHAMBER IS SO PURGED AND IF NECESSARY ADJUSTS THE LOGIC IN RESPONSE THERETO.

Abstract: A particle detection system 600 including; at least one light source (606) adapted to illuminate a volume being monitored (610) at at least two wavelengths; a receiver (604) having a field of view (620) and being adapted to receive light from at least one light source (606, 607) after said light has traversed the volume being monitored and being adapted to generate signals indicative of the intensity of light received at regions within the field of view of the receiver; a processor (624) associated with the receiver (604) adapted to process the signals generated by the receiver to correlate light received at at least two wavelengths in corresponding regions within the field of view of the receiver and generate an output indicative of the relative level of light re-ceived at the two wavelengths.

Abstract: The invention relates to a particle detector, systems, and methods for detecting the presence of particles in a volume of air, most particularly it relates to detection systems and methods that use multiple modes of detection to detect the presence of particles. Preferably the particles being detected are particles that indicate an actual or incipient fire, or pyrolysis, such as smoke.

Abstract: In one form the present invention provides a method of detecting particles in an air sample, including (a) obtaining an air sample, (b) reducing the concentration of particles in the air sample, (c) detecting a level of particles in the air sample with reduced particle concentration, 5 and (d) applying a correction to the detected level of particles corresponding to the reduction in concentration of particles in the air sample produced in step (b).
