Abstract:CIRCULATORY ASSIST DEVICES ARE NEEDED FOR IMMEDIATE TEMPORARY TREATMENT OF ACUTE MYOCARDIAL INFARCTION AND FOR SOME POSTCARDIOTOMY PATIENTS. SINCE MORE THAN 30 YEARS AGO, THE EFFORTS OF A NUMBER OF RESEACHERS AND CLINICIANS HAVE RESULTED IN THE NOW WIDELY USED COUNTERPULSATION INTRA-AORTIC BALLOON… more
Abstract:PERSONAL SAMPLER PUMPS ARE WORN BY INDUSTRIAL WORKERS TO DETERMINE THE CONCENTRATION OF PARTICULATES TO WHICH THE WORKER HAS BEEN EXPOSED DURING A WORK SHIFT. USUALLY A PARTICULATE COLLECTION DEVICE, SUCH AS A FILTER, IS WORN IN THE BREATHING ZONE OF THE WORKER AND CONNECTED TO A BELT-MOUNTED PUMP… more
Abstract:Often with little knowledge of the per treatment efficiency as related to the individual patients needs, Hemodialysis is prescribed for over 400,000 patients worldwide. A methodology and apparatus are proposed for the quantification of urea removal during treatment. A prototype urea sensor will be… more
Abstract:The understanding of protein function is greatly enhanced by the availability of three-dimensionalinformation obtained by X-ray crystallography. Unfortunately the large, well-ordered three-dimensionX-ray analyses have been difficult to produce for membrane proteins since they tend more naturally… more
Abstract:DURING THE PAST 10 YEARS SIGNIFICANT PROGRESS HAS BEEN MADE IN THE PERFORMANCE CHARACTERISTICS OF SOLID-STATE DEVICES. THE OUTPUT POWER CAPABILITY HAS SUBSTANTIALLY INCREASED, THE EFFICIENCY HAS ALMOST DOUBLED, THE RELIABILITY, WHEN OPERATED CONSERVATIVELY, HAS ALWAYS BEEN BETTER THAN TUBES BEACUSE… more
Abstract:Cytogenetic studies indicate the presence of novel amplified DNAs specific for human breast cancersMYC, neu and PRAD1 have been found amplified in 5-40% of breast cancer biopsies and cell lines, andare amplified less frequently. Laborious approaches to clone DNA from the cytogenetic… more
Abstract:Almost all persons find it increasingly difficult to live independently as they age. Everyday mishaps assume great importance for elderly persons because the victims may be unable to respond actively. These people may need varying levels of surveillance for their own health, thereby, reducing their… more
Abstract:Hospitals and nursing homes restrain a significant number of patients, especially in bed. Restraintfrequently performed procedure in nursing homes. However, there is no rational reason to restrain pafrom injury, and patient restraint causes injuries and even death. Some alternatives to restraints… more
Abstract:Circuit simulation is a critical bottleneck in design of complex VLSI chips. Even though clock speed and processing power of general purpose workstations are improving constantly, increases in size and complexity of VLSI chips indicates that this problem will only get worse. In the past, this… more
Abstract:This project will determine the feasibility of developing a mission-information collection, analysis, and reporting system (MICARS) to meet the specific needs of an AF Special Operations Forces (AFSOF) squadron. MICARS will be maintained in a computerized relational database, and will generate… more
Abstract:The air of this proposal is to develop a noninvasive probe that may be placed near, but not on, the patient or the patient's wound, to measure the partial pressure of dissolved oxygen in the interstitial body fluids. The sensor is capable of assessing gas pressure levels in a graduated fashion from… more
Abstract:The objective of this project is to develop new or improved systems for electronic processing and management of text and images (film and video from electron and optical microscopes. Processing electronic images with film quality creates unique problems with both analog and digital formats. … more
Abstract:Electrical management of potentially lethal arrhythmias has been found to dramatically improve survcandidates at risk of sudden cardiac death. Over 40,000 Implantable cardioverter/defibrillators (ICDsince initial FDA approval in 1985. False positive delivery of shock remains a major problem and… more
Abstract:A batteryless and wireless sensor for intrusion detection and assessment of threats which requires no battery, external power or wiring is proposed. These types of sensors derive energy from passing vehicles or persons, and indicate their presence, location, speed, etc., via a self-generated… more
Abstract:Advances in impulse, or Ultra-Wideband (UWB) technology by ANRO Engineering, Inc. (ANRO) over the past 10 years now provide a firm foundation for advanced communication system applications, including video, voice, data and ranging information in an LPI/D waveform. A UWB data link is proposed to meet… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
