According to a NIDR survey on employed American adult's oral health, approximately 42% of those oldyears and 4% of those 35 to 65 years are totally edentulous. Additionally, by the age of 65, those waverage of ten, while those between the ages of 55 to 64 have lost nine. This tremendous number of ibenefit from dental implant therapy. Following tooth extraction, the edentulous ridge begins to resob ...

We will develop a computer program for automating the testing of medical diagnostic imaging equipmeprogram will run o the vast majority of existing PACS computers which many radiology departments alrdevelopment will provide testing methods for most medical image quality parameters which are much faexpensive than the largely manual alternative methods. This will allow hospitals and clinics to do aq ...

This project addresses the need for sensitive and predictive measures that can identify elderlypersons at risk for falling, thereby preventing some of the human and societal costs of devastatinginjuries. Dynamic balance assessment methods will be combined with virtual-reality techniques toproduce an innovative technology for evaluating balance in simulated real-world environments. Presenttechnique ...

A novel quantum well infrared photo transistor, which we call QWIPT, is proposed. By taking the advantage of the almost perfect alignment of the conduction band in GaAsSb/InAlAs system, it is possible to integrate such quantum wells into a QWIPT to improve the optical gain and, therefore, the detectivity of the p-QWIP. We expect, by incorporating molecular beam epitaxy growth interruption scheme, ...

The long-term objective of CCT is to develop and commercialize new transesophageal (TE) pacing systAvailable systems pace only the atria, but one, the other, or both heart chambers must be paced to sneeds in medical emergencies and Advanced Life Support protocols. This application describes clinicaprototype probes for TE atrial and/or ventricular pacing, including one for simultaneous pacing and(E ...

The traceability of on-wafer calibration standards has long been an issue among the microwave measurement community, and the proliferation of new calibration methods, elements, and applications only exacerbates the problem. This diversity in calibration needs has made traceability of a physical reference impractical. As a result, the NIST developed a procedure which can compare on-wafer calibrat ...
