The Technology

DDS Detection products can detect vapors that have light absorption wavelengths in the Ultraviolet, Visible, or IR spectrum.

The DDS optical detection system is a software centric product, independent of the camera type that continuously monitors an area and automatically provides an audible and visual alarm in the control center when fugitive emissions are detected. Detection targets are not limited to hydrocarbons and can be applied to detect any vapor that has a light absorption wavelength in Ultraviolet, Visible, or IR spectrum with the capability to segregate and focus on specific vapors.

The base system was commercially deployed to detect smoke and fire in harbors, large industrial sites and forests. Delacom directed the development of fugitive vapor detection, successfully tested the system with consumer grade, industrial visible range and industrial IR cameras and acquired patent protection.

Contributing factors that make this system a powerful tool are:

• It analyses and evaluates the image rather than attempting to match the image to an existing library as in image recognition software.
• It reduces the image to its mathematical components providing the system with the capability to identify each small component, edge and movement within the image.
• The use of Hidden Markov Models, a system used in voice recognition, and the ability to provide pre guidance for the Hidden Markov Models permits flexibility in changing conditions and focus on specific compounds.

Automatic detection is annunciated by an audible alarm and a visual location indicator at the control station. System capability includes recording, search and retrieval functions with the recording option selectable as continuous or only on event. Communication between the sensor and the control station can be wired or wireless and the control station can be local, remote or both.
