Diode-laser arrays operating in the visible region of the spectrum offer advantages for illuminator applications, particularly for night and water penetration capability. Recent developments in diode-laser materials allow operation throughout the visiblespectrum. At this time, red diode-laser technology is more mature than the existing blue-green or violet diode-laser technology. The novel aspe ...

The Anti-Submarine Warfare Commander (ASWC) has a crucial responsibility to protect against surface and subsurface threats, which requires keeping track of contacts and making safety-critical decisions. The Undersea Warfare Decision Support System (USW-DSS) supports the ASWC and his team by providing a"Common Tactical Picture"via the Master Tactical Plot (MTP). However, evolving sensor and data fu ...

THE PROPOSED PROGRAM WOULD RESULT IN THE DEVELOPMENT OF A PORTABLE FIELD INSTRUMENT FOR THE MEASUREMENT OF AMBIENT AIR TEMPERATURE TO AN ABSOLUTE ACCURACY OF 0.01 DEGREES CENTIGRADE. THE PROPOSED INSTRUMENT WOULD SUBSTANTIALLY IMPROVE OUR ABILITY TO MEASURE AMBIENT AIR TEMPERATURE AND, IN ADDITION, IT WOULD BE ACCURATE ENOUGH SO THAT IT COULD BECOME A STANDARD INSTRUMENT FOR THE CALIBRATION OF FIE ...

NON-TECHNICAL SUMMARY: The sugar industry produces over 100 million tons of sugar each year. This large industry has been intrigued by the use of membranes to enhance the efficiency of production for many decades but membranes that have the correct combination of performance and cost have not yet been developed for consideration in large scale installations. High temperature, high viscosity, and m ...

The sugar and grain processing industries produce tens of billions of dollars worth of product each year. These industries have used membrane technology for some applications but membrane durability limits their widespread utilization. At present, there are no commercial cost-effective membranes that have the requisite process performance and lifetime for many applications within these industries. ...

The purpose of the proposed project is to produce a commercial abrasive blasting nozzle which is more efficient and quieter than a typical commercially-available nozzle. The nozzle will decrease labor hours needed for blasting processes in shipbuilding, decrease workers compensation claims due to hearing loss, and relieve environmental noise restrictions on blasting at shipyards. All of this will ...

An abrasive blasting nozzle is a complex aero-acoustic noise source, characterized by super-sonic, two-phase flow. Noise from an abrasive blasting nozzle is comprised of three sources: (i) turbulent mixing noise (ii) shock-associated noise and (iii) jet impingement noise. It is not uncommon for abrasive nozzles to generate noise levels greater than 120 dB(A); far exceeding typical occupational noi ...

Bridger Photonics, Inc. will develop an absolute length metrology sensor that will simultaneously provide >1,000 measurements per second, 0.5 m maximum measurement distance. Bridger’s solution is will fill a gap in precision measurement technology for applications that require rapid monitoring of macroscopic distances such as positioning and calibration of surface metrology systems (CMM, AFM, SE ...
