The Multiple Degree of Freedom Measurement (MDFM) System, developed under Wright Laboratory, has been identified as having strong commercial potential as a significant enhancement to existing products in the machine tool industry for machine tool calibration or coordinate measuring machine enhancement. The MDFM is in need of revision to incorporate state-of-the-art technology, to prepare the devi ...

The adaptive single user receiver invented at AF LAB has been shown to suppress multiuser and certain forms of narrow-band interference in adecision directed mode during the entire transmission, without requiring knowledge of other users spreading codes, timing or phase information in direct-sequence proposal, we investigate the use of our single user receiver for secure communications as required ...

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 ...

Mistakes made by programmers in the use of pointer variables and dynamic memory allocation is a significant cource of software errors. The development of a suite of tools to aid in the detection of these errors is addressed. These tools will operate both statically and dynamically in order to provide as wide a range of services as possible. The static tool will guarantee that certain pointer ba ...

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 ...
