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 ...

This SBIR proposal addresses a high priority DoD need for an improved man-portable magnetic sensor to detect and localize mines and UneXploded Ordnance (UXO). UXO field testing has clearly shown the superiority of magnetic-based technology over other technologies such as ground penetrating radar and infrared sensors. Total field magnetometers and gradiometers, although relatively unaffected b ...

Sheet metal products have made an indispensable place for themselves in our day to day lives. Light weight, good surface finish, low finished product cost, and relatively good formability are just few of the many features that make the sheet metal products so attractive. This includes all the product lines such as automotive, aerospace, appliance, construction, instruments, heating and ventilati ...

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 trend toward replacement of highly toxic chemicals with less hazardous alternatives has created the demand for replacement of chromate conversion coatings for corrosion protection of aluminum alloys. Aluminum alloys are the predominate structural material used in aircraft because of their high strength-to-weight ratios, affordability and processability. Aluminum is subject to catastrophic fail ...

Not Available In the course of developing the solar powered Pathfinder and Centurion high altitude long endurance (HALE) uninhabited air vehicles (UAVs), AeroVironment has done extensive investigations into the effects of atmospheric turbulence on this unusual class of aircraft. This investigation found that turbulent loads are the driving factor in the design of these vehicles. In particular, ...

The main objective of this Phase I program will be to develop a release coating for use with ceramic tooling that will be capable of withstanding cure temperatures in excess of 700F and will have high solvent vapor permeability. The main approach will be to formulate a high temperature film forming silicone resin system by investigating improvements of silicone resins that will be modified with p ...

Federal, state, local, and military missions for Disaster Relief, Emergency Action, and Humanitarian Assistance (DREAHA) require all of the traditional command, control, communications, computer and intelligence (C4I) functions used by military units for traditional warfare. New civilian systems that leverage and reuse military C4I systems to plan, prepare, identify, vector, monitor, and recover ...
