Methods and devices are disclosed for detecting vulnerable atherosclerotic plaque, or plaque at risk of reducing blood flow in a vessel, by identifying a region of elevated temperature along a living vessel wall. The disclosure that human atherosclerotic plaque with measurable temperature heterogeneity has the morphological characteristics of plaque that is likely to ulcerate provides a new and sensitive technique for detecting and treating these dangerous plaques before myocardial infarction and its consequences occur. The disclosed methods are advantageous over conventional plaque detection techniques because they are capable of differentiating between those plaques that are at great risk of rupture, fissure, or ulceration, and consequent thrombosis and occlusion of the artery, and those that are not presently at risk. Infrared heat-sensing catheters useful for identifying potentially fatal arterial plaques in patients with disease of the coronary or other arteries are also described. In some embodiments a coherent infrared fiber optic bundle is employed to radially and longitudinally explore a luminal wall to identify inflamed, heat-producing, atherosclerotic plaque. Certain other methods and devices are disclosed which are particularly suited for non-invasively identifying and then monitoring the progression or amelioration of an inflamed plaque in a patient, and for monitoring for onset of inflammation in an implanted arteriovenous graft. Also disclosed are thermocouple basket catheters and thermistor basket catheters which are also capable of detecting temperature heterogeneity along a vessel wall.

A computer system having a fault-tolerance framework in an extendable computer architecture. The computer system is formed of clusters of nodes where each node includes computer hardware and operating system software for executing jobs that implement the services provided by the computer system. Jobs are distributed across the nodes under control of a hierarchical resource management unit. The resource management unit includes hierarchical monitors that monitor and control the allocation of resources. In the resource management unit, a first monitor, at a first level, monitors and allocates elements below the first level. A second monitor, at a second level, monitors and allocates elements at the first level. The framework is extendable from the hierarchy of the first and second levels to higher levels where monitors at higher levels each monitor lower level elements in a hierarchical tree. If a failure occurs down the hierarchy, a higher level monitor restarts an element at a lower level. If a failure occurs up the hierarchy, a lower level monitor restarts an element at a higher level. Each of the monitors includes termination code that causes an element to terminate if duplicate elements have been restarted for the same job. The termination code in one embodiment includes suicide code whereby an element will self-destruct when the element detects that it is an unnecessary duplicate element.

The invention can work reliably at ultra-low speed even if the rotating speed of motor is close to zero.
