Highway queue warning provides early congestion estimation to motorists and reduces potential delay by allowing them to either change lanes or take alternate routes. It can facilitate effective highway operations as well as lower energy consumption and greenhouse gas emission by preventing traffic from congestion. Quality of the estimation depends heavily on real-time traffic data. This paper proposes...
We discuss how sensor technologies have enabled the development of proactive energy management (EM) systems. At the same time, we discuss how these emerging EM systems motivate the development of new sensor technologies. Proactive EM systems integrate advances in weather forecasting, sensors, predictive models, and real-time optimization algorithms to anticipate uncertain factors that affect energy...
This paper reviews the comparison of a newly developed ultrasonic gas flow meter with a standard hot wire thermo-anemometer flow meter. The flow meters are compared utilizing a wind tunnel to induce flow through the meters. The ultrasonic gas flow was been developed and demonstrated under a NAVAIR-sponsored program. The ultrasonic meter uses acoustic pulse trains to measure gas flows through pipes...
Future industrial use of wireless instrumentation will undoubtedly increase dramatically in the coming years. Deployment of such instrumentation in an industrial setting - with its security and robustness criteria that are much more stringent than residential performance criteria - hinges on user acceptance of verified performance as well as meeting cost requirements. Today, circa 2011, these industrial...
FPGAs have changed the way we collect data and implement control systems. With the processing power they contain, we can easily turn data into information by performing in-line processing at very high acquisition rates. This allows engineers and scientists to test and develop very fast control algoritm loop rates. Join us for this presentation that looks at the applications where FPGAs are getting...
We saw that wireless was inevitable and made an early commitment to wireless technology for industrial monitoring and, ultimately, control. Our company investigated options and even built some early prototypes. As we were approaching the production phase, we got more involved with ISA100 and the development of their first-to-be-released ISA100.11a, targeting process monitoring and “soft” control....
America's 4.7 million commercial buildings account for nearly one-fifth of the U.S. energy consumption. Studies estimate that commercial building instrumentation and control systems that can provide energy management and control, HVAC commissioning, HVAC fault detection, and lighting management have the potential to reduce up to 30% energy consumption. The most significant key enabler for this progress...
Biometric authentication modalities such as face and iris recognition provide a minimally invasive means to uniquely identify individuals and verify identity. Most commercially available biometric systems perform authentication based on a single modality and/or only capture features from a short distance. Most existing standoff iris sensors capture at a lower frame rate, lower resolution, and wider...
Vehicle detection has been dominated for several decades by magneto-inductive sensors including inductive loop sensors. The detection electronics estimate the frequency of an oscillator that changes dependent upon the inductance of the sensor. The algorithms used to estimate the sensor inductance and to detect vehicles are proprietary and vary between manufacturers. This has limited research in this...
Renewable biofuels are primary research targets as sources for sustainable, net-zero-carbon, alternative energy. In this vein, we are developing an imaging device for whole plant measurement of vascular and metabolic processes. It will provide new information geared towards increasing the output of biofuels and the resilience of plant feedstock. Single Photon Emission Computer Tomography (SPECT) is...
Power Supply Controls are being developed at Oak Ridge National Laboratory (ORNL) to test transmission line components of the Electron Cyclotron Heating (ECH) system, with a focus on gyrotrons and waveguides, in support of the International Thermonuclear Experimental Reactor (ITER). The control is performed by several Programmable Logic Controllers (PLC's) located near the different equipment. A technique...
