Abstract: A coke drum measurement system includes a first target coupled to an upper aspect of a coke drum and a second target arranged generally perpendicular to the first target. A first optical measurement device is arranged to visualize the first target and measure a distance between the first optical measurement device and the first target. A second optical measurement device is arranged to visualize the second target and measure a distance between the second optical measurement device and the second target. A processor is electrically coupled to the first optical measurement device and the second optical measurement device. The processor receives signals from the first optical measurement device and the second optical measurement device corresponding to movement of the coke drum. The processor aggregates signals received from the first optical measurement device and the second optical measurement device to determine a total movement of the coke drum.

Abstract: A controlled cold therapy apparatus for treating body portions of an animal. The apparatus includes an appliance configured to fit over the body portion to be treated such that substantial total surface area contact is obtained between the body portion to be treated and the appliance. The appliance is comprised of a liquid impervious material which includes a liquid supply connector and a liquid return connector opened to internal flow channels to enable cooled liquid to be circulated through the appliance in a U-shaped flow pattern. The appliance is surrounded by an insulating jacket and is preferably secured around the body portion to be treated by hook and loop fastener strips. The apparatus further includes a liquid control station which circulates cooled liquid through the appliances connected thereto. The liquid control station may be a portable unit or a central fixture unit incorporated into a structure for treating multiple animals at the same time.
