Patent number: 8043223Abstract: A method and system for use in measuring the endothelial dysfunction utilizing flow mediated dilation and determining arterial health of a patient. The system includes a non-invasive blood pressure monitor, an ultrasound system and a pulse oximeter monitor that all communicate with each other to perform the flow mediated dilation. Initially, the ultrasound transducer, blood pressure cuff and pulse oximeter sensor are positioned on an arm of the patient. The blood pressure cuff is inflated to occlude an artery for an occlusion period. Following the occlusion period, the ultrasound system is automatically signaled to begin determining a parameter of the artery, such as diameter, and the flow rate of blood through the artery without any operator intervention. At the same time, the pulse wave velocity PWV is calculated between the ultrasound transducer and the finger probe of the pulse oximeter following the occlusion period.Type: GrantFiled: November 22, 2006Date of Patent: October 25, 2011Assignee: The General Electric CompanyInventors: Bruce A. Friedman, Kai E. Thomenius, Aaron M. Dentinger

Patent number: 8016761Abstract: A method and system for use in measuring the endothelial dysfunction in a patient utilizing flow mediated dilation. The system includes both a non-invasive blood pressure monitor and an ultrasound system that communicate with each other to perform the flow mediated dilation. Initially, the ultrasound transducer and blood pressure cuff are positioned on an arm of the patient and the blood pressure cuff is inflated to occlude an artery for an occlusion period. Following the occlusion period, the ultrasound system is automatically signaled to begin determining both the diameter of the artery and the flow rate of blood through the artery without any operator intervention. Based upon the detected characteristics of the artery before and after occlusion, the system can determine the endothelial dysfunction of the patient.Type: GrantFiled: October 23, 2006Date of Patent: September 13, 2011Assignee: The General Electric CompanyInventors: Bruce A.

Patent number: 6034717Abstract: A desktop-based stereoscopic projection display system affording high-resolution stereoscopic and peripheral viewing of three-dimensional color imagery over a field of view of at least 180.degree.. The projection volume required by each image projector of the display system is disposed substantially within the overall display volume of the display system, while maximizing the viewing volume within which the viewer is free to move during interactive stereoscopic viewing sessions. The display system utilizes high-resolution image projectors, keystoning correcting optics and projection-beam folding mirrors which are compactly mounted immediately above the upper volume-boundary surface of the overall display volume of the system, in order to permit the use of three-dimensional display structures having footprints and display volumes that are supportable upon desktops and in other viewing environments characterized by spatial restrictions.Type: GrantFiled: March 22, 1996Date of Patent: March 7, 2000Assignee: Reveo, Inc.Inventors: Aaron M. Dentinger, David C. Swift, Sadeg M. Faris
