Delta Controls Award-Winning O3 Sensor Issued U.S. Patent Approval

SURREY, BC, Dec. 14, 2021 /PRNewswire/ -- Delta Controls award-winning O3 raised its profile higher with the recent issue of a new U.S. patent approval on the BAS (Building Automation System) technology and method behind the innovative product.

Chief Technology Officer for Delta Controls, Chris Kwong — a 28+ year veteran of the firm — provided details about this exciting development in a video interview and said, "The newly acquired patent is all about sensor fusion. This technology features multiple sensing devices to establish a system that allows creation of machine learning trained linear models and algorithms that estimate the temperature at a location within the sensor's field of view."

Kwong continued, "Most significant about this newly patented device is its use of the multiple sensors to obtain a highly accurate value of temperature at significantly different locations to increasingly optimize any space when compared with traditional methods. It's more accurate due to its location and more instantaneous than other methods allowing us to control more efficiently."

Moving forward with this patent and method, Delta Controls can expand on other innovative concepts and ideas. It allows the application of machine learning techniques, build models and algorithms facilitating more accurate measurement of other data and performance points.
