THE USE OF LASERS AS A SURGICAL MODALITY HAS BEEN ESTABLISHED IN RECENT YEARS. LASERS OF VARIOUS WAVELENGTHS ARE SUITED FOR DIFFERENT SPECIFIC SURGICAL FUNCTIONS. CO2 (10.6 ) RADIATION HAS SMALL PENETRATION DEPTHS IN TISSUES. THIS LEADS TO HIGH SURFACE TEMPERATURES WHICH ARE DESIRABLE FOR TISSUE INCISION THROUGH EVAPORATION. ND:YAG LASERS (1.06 ) PROVIDE VOLUMETRIC TISSUE HEATING WHICH IS EFFECTIV ...

THE OBJECTIVE OF THIS PROPOSAL IS THE DEVELOPMENT OF A PULSED MID-IR LASER IN THE 3.5 TO 4.1 MICROMETER ATMOSPHERIC TRANSMISSION WINDOW. SUCH SPECTRAL SOURCE IS RELEVANT TO A VARIETY OF TACTICAL APPLICATIONS. THE DF CHEMICAL LASER HAS BEEN THE CHOICE, BUT SUFFERS FROM WASTE FUEL MANAGEMENT PROBLEMS. NO OTHER EFFICIENT DIRECT LASING SOURCE IS AVAILABLE. TO OBTAIN SUCH A SOURCE, WE PROPOSE THE USE O ...

THE SCATTERING OF X-RAYS CAN BE USED TO IMAGE THE DENSITY OFANATOMICAL STRUCTURES UP TO SEVERAL CENTIMETERS DEEP IN THE HUMAN BODY. THIS RESEARCH DESCRIBES A TECHNIQUE OF USING COMPTOM SCATTERED X-RAYS IN AN IPSILATERAL (BACKSCATTER) GEOMETRY TO OBTAIN THREE-DIMENSIONAL DENSITY INFORMATION FORMAXILLODENTAL IMAGING. THE TECHNIQUE IS CALLED COMPTON SCATTER TOMOGRAPHY (CST). CURRENTLY, IN THIS ANATOM ...

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 ...

THIS THREE PHASE PROJECT IS DESIGNED TO ASSIST DISABLED STUDENTS IN TRANSITION FROM SCHOOL TO WORK BY PROVIDING TWO NEW MICROCOMPUTER-BASED PROGRAMS TO REHILITATION SPECIALISTSIN THE WISCONSIN DIVISION OF VOCATIONAL REHABILITATION SPECIAL SERVICES UNIT WHICH ANNUALLY EVALUATES AND SCREENS OVER 700 YOUNG HANIDCAPPED PERSONS SEEKING TO LEAVE SCHOOL AND ENTER THE WORKPLACE. THESE PROGRAMS ARE DESIGNE ...

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 ...
