| 20120079871 | GAS DETECTOR APPARATUS - An apparatus and methods for detecting the presence of gases is described. The gas detection apparatus includes, a housing adapted to be in fluid communication with a duct of a particle detection system, and at least one gas detector sensitive to a target species arranged in fluid communication with the housing to detect the presence of the target species in at least part of the air sample flowing in a duct. In one form the gas detection apparatus forms part of a system for detecting a condition in an environment that includes, a particle detector; a duct system in fluid communication with the environment and the particle detector and an aspirator to draw an air sample flow from the environment to the particle detector. | 04-05-2012 |
| 20110221889 | PARTICLE DETECTION - A particle detection system including; at least one light source adapted to illuminate a volume being monitored at least two wavelengths; a receiver) having a field of view and being adapted to receive light from at least one light source 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 associated with the receiver adapted to process the signals generated by the receiver to correlate light received 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 received at the two wavelengths. | 09-15-2011 |

| 20100039645 | METHOD AND SYSTEM FOR PARTICLE DETECTION - An apparatus for detecting particles in an airflow is disclosed. The apparatus can include at least one light source for illuminating a one or more portions of the airflow, at least one photo-detector positioned to detect light scattered from one or more illuminated volumes of the airflow. The at least one light source and at least one photo detector are arranged such that a signal indicative of light scattered from a plurality of illuminated volumes can be derived from the output of the at least one photo detector. The apparatus also includes a signal processing apparatus configured to process said signals indicative of light scattered from a plurality of illuminated volumes to determine whether particles have been detected in the airflow. | 02-18-2010 |
