Truck-mounted pavement deflection monitoring system using high-precision laser scanners and inertial sensors
A new easy to use universal pavement deflection monitoring system to monitor road healthThe deflection of pavement when a moving vehicle passes over it is an important measure of its condition. Since pavement damage is initially not visible on a road’s surface, pavement deflection should be measured as often as possible for the efficient maintenance...

A cost-effective downhole strain sensor tool for retrofit or new installation
Problem statement Hydraulic fracturing involves fracturing of bedrock formations by pressurized liquids and is one of the key technologies used for unconventional oil production. Usually strains on the order of 10–5 to 10–6 propagate ahead of the fractures. Monitoring and characterizing the strain on wellbores can be a formidable challenge,...

Advanced sensors for RT determination of mud density and flow rate in high-pressure conditions
Problem statementLost circulation can have disastrous consequences including blowout (uncontrolled kicks) and loss of life, so close monitoring to quickly assess and control such events is essential. Market estimates indicate that over $2 billion USD is spent annually to combat and mitigate these events. Real-time measurement of mass flow is critical...
