THE OBJECTIVE OF THIS PROGRAM IS TO DESIGN AND BUILD A STAPLER FOR PERFORMING END-TO-END AND END-TO-SIDE ANASTOMOSES ON MEDIUM TO LARGE VESSELS, AND FOR REPAIRING BLOOD VESSELS AND VASCULAR ANEURYSMS, AND TO DEVELOP A SURGICAL PROTOCOL FOR ITS USE. THE METHOD PROPOSED USES A SPECIAL STAPLER AND CONFIGURATION OF STAPLES WHICH MINIMIZESBLOOD CONTACT WITH THE STAPLES, DOES NOT RESTRICT THE FLOW OF BL ...

The objective is an optical periodontal probe tailored to automatically measure and record multiple tissue parameters deemed important for disease detection and treatment monitoring. As a first step in the development of a multi-functional device, a probe designed to mimic the visual measurements made by dental clinicians to determine pocket depth, bleeding on probing (BOP) and tissue coloration w ...

THE PROPOSED WORK INVOLVES APPLICATION OF SUPPORTED MOLTEN SALT CATALYSIS TO THE CATALYTIC ENDOTHERMIC DEHYDROGENATION OF HIGH ENERGY-DENSITY AVIATION FUELS. THE CATALYSTS OF INTEREST ARE HETEROGENEOUSLY DISPERSED PLATINUM AND NICKEL, TO BE USED ALONE OR IN BIMETALLIC CLUSTERS. THE MOLTEN SALTS TO BE USED INCLUDE BINARY AND TERNARY EUTECTICS INVOLVING ALKALI METAL CHLORIDES AND HYDROXIDES. THE SUP ...

N/A

THE DEVELOPMENT OF A WHEELCHAIR ACCESSIBLE, ADJUSTABLE SINK/COUNTER SYSTEM IS OF INTEREST TO ARCHITECTS, BUILDERS, AND DEVELOPERS AS A WAY OF MEETING LEGAL REQUIREMENTS AND THE NEEDS OF THEIR CLIENTS. THEY ARE ESPECIALLY INTERESTED IN COMPONENTS THAT LEAD TO VIRTUAL INDISTINGUISHABILITY BETWEEN HANDICAPPED-ACCESSIBLE AND STANDARD APARTMENTS, SINCE PROPERTY OWNERS FREQUENTLY HAVE DIFFICULTY LEASING ...

N/A

Two approaches are proposed to attack the problems of fixturing process. First, a novel hardware holding system, Dexterous Vise, is proposed. Functionally, a single Dexterous Vise is capable of revealing four faces of the clamped workpiece to the cutting tool without re-fixturing, which actually increases one degree of freedom to the machine tool. A pair of Dexterous Vises, the "Dual-Vise", ena ...

N/A

Herein, an innovative aircraft weighing system based on a set of piezopolymar film pad sensors is described. The wieghing system, which would operate automatically as the aircraft taxi over it, would be unobtrusive, accurate, and reliable. These sensor pads could be integrated into the flight deck surface below the grated rubber surface finish. These thin (20-30 mils) piezopolymer sensing pads ...
