Because of the scarce network bandwidth available on the wireless links, data compression plays a critical role in the wireless system design. We propose to evaluate existing public-domain and commercial lossless data compression packages in the context of wireless networking. The specific criteria used include compression efficiency, compression speed, memory usage, and ease of being incorporat ...

The final prototype of the Microcircuit Board Repair apparatus will be capable of laying down or lifting metal strips with micrometer dimensions. Under real time computer control, the translation stages will be fully automated or manually controlled. The end user will monitor the process in real time using a camera attached with the source. Laying down the metal lines will be done using Laser C ...

An improved computer module for representing rotor flow field effects on flight dynamics response is proposed for development. This model extends finite-state dynamic inflow models to address current limitations in predicting rotorcraft off-axis response to control inputs. The software module also includes features for representing rotor operation in the vortex ring state. The model is novel ...

THE U.S. WEATHER SERVICE PRESENTLY USES A "TIPPING BUCKET" RAIN GAUGE FOR MEASURING RAIN ACCUMULATION. THIS DEVICE IS SENSITIVE TO WIND AND MOTION (AS ON BUOYS), CANNOT MEASURE RAIN RATE, AND REQUIRES FREQUENT MAINTENANCE, BECAUSE OF MOVING PARTS. AN ALTERNATIVE DEVICE IS BEING PROPOSED, WHICH INCORPORATES A RIGID, RESONANT TUBE, CLOSED AT THE TOP BY AN ELECTRO-ACOUSTIC TRANSDUCER, AND AT THE BOTT ...

Objectives of this project include the development of electrochemical techniques for measurement of (i) thinckness of OSP coatings, (ii) amount and type of copper oxides within and under the OSP coating, (iii) protective effectiveness of OSP coatings, and (iv) solderability prediction of OSP-coated PWBs. We will evaluate the effect of major parameters of the coating, storage, and soldering proces ...

INTERNATIONAL MICRO INDUSTRIES (IMI) IS WELL QUALIFIED TO PERFORM THE SCIENTIFIC AND ENGINEERING RESEARCH (PHASE 1) REQUIRED TO DEFINE A HYBRID SMARTCARD READER (HSR) IN A PCMCIA CARD FORM FACTOR, AND TO DEVELOP IT IN PHASE 2. THE PROBLEM IS HOW TO PROCESS, INTERCONNECT AND ASSEMBLE A NUMBER OF HIGH PERFORMANCE, HIGH LEAD COUNT, KNOW-GOOD UNPACKAGED (NAKED) SEMICONDUCTOR CHIPS TO CREATE A HYBRID S ...

MSI PROPOSES TO INCORPORATE BACKGROUND SUBSTITUTION OF "FAULTY MODELS" IN CAD DESIGN SIMULATION OF ELECTRONIC CIRCUITS TO PERFORM A "DESIGN OF EXPRIMENTS" DETERMINATION OF SENSITIVITY TO PARAMETRIC VARIATION IN COMPONENTS. THE INFORMATION LEARNED WILL BE USED TO SELECT COMPONENTS THAT WILL HAVE A LONGER LIFE, AND GREATER DURABILITY. THIS FORM OF ANALYSIS COMBINED WITH WORST CASE SENSITIVITY ANALYS ...
