Patent number: 9057485Abstract: A beam detector including a light source, a receiver, and a target, acting in cooperation to detect particles in a monitored area. The target reflects incident light, resulting in reflected light being returned to receiver. The receiver is capable of recording and reporting light intensity at a plurality of points across its field of view. In the preferred form the detector emits a first light beam in a first wavelength band; a second light beam in a second wavelength band; and a third light beam in a third wavelength band, wherein the first and second wavelengths bands are substantially equal and are different to the third wavelength band.Type: GrantFiled: August 4, 2014Date of Patent: June 16, 2015Assignee: Xtralis Technologies LtdInventors: Ron Knox, Karl Boettger, Kemal Ajay

Patent number: 9002065Abstract: A smoke detecting method which uses a beam of radiation such as a laser (16), to monitor a region, such as a room (12). A camera (14) is used to capture images of part of the room (12), including a path of the laser beam. Particles in the laser beam scatter light (30), and this is captured by the camera (14) for analysis. A processor (20) extracts data relating to the scattered light (30) to determine the density of particles in the beam, to determine the level of smoke in the region. The laser may have a modulated output (38) so that images captured without the laser tuned “on” can be used as a reference point and compared to images taken with the laser turned “on”, to assist in determining the level of scattered light (30) compared to ambient light. Filters (24, 26) may be used to decrease signals generated from background light.Type: GrantFiled: November 25, 2013Date of Patent: April 7, 2015Assignee: Xtralis Technologies Ltd.Inventors: Ron Knox, Karl Boettger, Peter Meikle, Brian Alexander

Patent number: 8314710Abstract: The present invention relates to a system for determining particle transmittance Tx of a filter for use with a particle detection system to provide a filter warning for aspirated particle detection systems by detecting a level of first particles having a size indicative of smoke particles and which pass through the detection system; determining an integrated smoke hours value by integrating the detected level of first particles over time; estimating the smoke particle transmittance Tx of the filter by applying a predetermined weighting operation to the integrated smoke hours value. An empirical measure of a filter's particle transmittance Tx, due to at least first particles having a size indicative of smoke particles may be achieved by way of integrating a level of such first particles passing through a particle detection system over time to determine the proportion of smoke particles arrested by a filter, “integrated smoke hours”.Type: GrantFiled: August 16, 2010Date of Patent: November 20, 2012Assignee: Vision Fire & Security Pty LtdInventors: Ron Knox, Karl Boettger

Publication number: 20120154161Abstract: A particle detector including a chamber, a first aspirator, a sensor(s), a controller and clean air supply. 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, 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.Type: ApplicationFiled: July 7, 2010Publication date: June 21, 2012Applicant: Xtralis Technologies LtdInventors: Ron Knox, Karl Boettger
