A low-cost, miniaturized Low Light Level (LLL) CCD TV camera system capable of more than 400 TV lines per picture height at an illumination level ranging from moonless starlight (10 E-4 foot candles) is proposed. The electro-optical portion of the system will incorporate an input lens with an electrically controllable iris, a GEN III image intensifier, a coupling lens and a 2/3-inch CCD. With care ...

There is a need for a reliable High Energy Laser Wavefront Analyzer (HELWA) to be used for beam quality testing at the Army's High Energy Laser Systems Test Facility (HELSTF). Accurate HEL wavefront measurements are critical to HEL device performance evaluation. Current devices are inflexible and difficult to maintain due to size, complexity, and a dependence of high precision moving parts. This e ...

The objective of the proposed Phase I effort is to perform a preliminary design of an electronically scanned antenna capable of supporting a multimode radar testbed operating in MTI, ultra-high range resolution and SAR modes. The proposed baseline antenna concept consists of four major components: a two-dimential antenna array of polarization-diverse radiating elements, a dual purpose elevation fe ...

Brimrose proposes to research and build in this Phase I program, a novel miniature spectroradiometer for measuring spectral incident, reflected, and transmitted irradiance of floating ice ocvers at visible wavelength (400-700 nm). This spectroradiometer is incorporated with a Brimrose acousto-optic tunable filter (AOTF). An AOTF uses an ultrasonic wave in a crystal to achieve fast and broadband sp ...

ONE OF THE PROBLEMS FACED BY MAINSTREAM SCHOOL PROGRAMS IS THE LACK OF QUALIFIED SIGN LANGUAGE INTERPRETERS AND THE EXPENSE OF THE INTERPRETERS WHICH ARE AVAILABLE. THE PROJECT PROPOSED HEREIN WILL INVESTIGATE THE USE OF SPEECH RECOGNITION EQUIPMENT AND DESIGNATED SPEAKERS AS A POSSIBLE SUPPLEMENT TO SIGN LANGUAGE INTERPRETERS IN THE CLASSROOM. SPEECH RECOGNITION TECHNOLOGY HAS MADE SIGNIFICANT ST ...

DRT proposes to develop a novel no-moving-parts pump that delivers flow of oxygen-enriched air, on the order of liters per minute at any desired pressure, without any pulsations or flow noise. A pump operating off a vehicular battery could weigh less than 8 lb. with a size of less than 1 cubic foot. It is based on a demonstrated chemical and biological agent purifying oxygen pumping system, where, ...

THE GOAL OF PHASE I IS TO SHOW THE FEASIBILITY AND VALUE OF A LARGE NATIONAL DATABASE WITH NAMES AND PERTINENT DEMOGRAPHIC INFORMATION TO DERIVE A REPRESENTATIVE SAMPLE OF DEAF AND HARD-OF-HEARING ADULTS. THIS DATABASE WILL SERVE AS A RESOURCE FOR INVESTIGATORS REQUIRING ACCESS TO DEAF AND HEARING IMPAIRED RESPONDENTS, INFORMANTS, COLLABORATORS, AND RESEARCH PARTICIPANTS. ATTEMPTS TO STUDY THIS PO ...
