A self-cleaning camera created by ExcelSense Technologies, a UBC-based venture, has cut maintenance downtime at one of the log lines in a British Columbia sawmill by almost 60 per cent. By providing the ability to see a critical but previously invisible process on the worksite, the technology enabled millworkers to prevent a recurring clogging problem from developing on multiple occasions.

“We wanted to offer a reliable, economical solution to an issue faced by many industrial worksites: the inadequate surveillance of key operations because of the absence of cameras or the repeated contamination of existing cameras,” says ExcelSense founder and CEO Nima Nabavi (BASc '05, MASc '06, MECH), PEng. “In most industrial settings, a normal camera would likely need to be cleaned by external means every few minutes.”

Owned and operated by Canfor, the BC mill had been dealing with frequent clogs at the outfeed of one of its log lines — an enclosed area where sawdust, oil and pitch would accumulate. If they could see what was happening inside, millworkers would have an opportunity to intervene before a clog developed and damaged equipment or otherwise interrupted production. But due to the constant flow of material into the area, installing regular cameras there would have provided no benefit; their view would have been obstructed in a matter of minutes.
