A system for interfacing between a user and a computer includes a microvideo display monitor, which may be mounted in a position which is substantially fixed relative to a given eye of the user, and a video input device which obtains an image of the given eye. The video input device is maintained in a fixed spatial relationship with the microvideo display monitor. From the image of the user's eye obtained by the video input device, the location on the display on which this eye is focused may be determined. A computer which controls the generation of selected displays on the microvideo display monitor responds to the eye focus location to perform predetermined functions. A voice or speech recognition unit may also be used to provide inputs to the computer. The computer may then perform predetermined functions in response to any combination of speech, and eye location data. The system may also be used for identification of the user and to determine whether the user is impaired.

Sensory integrated data interface

A technique is disclosed for using electrochemical noise (ECN) to charactze halide pitting reactions on a high strength aluminum alloy. ECN signals resulting from the pitting interaction of an aqueous halide solution with the oxide film on the aluminum alloy sample are measured. The signals are amplified, digitized, and then transferred to a digital computer where they are transformed from the time domain to the frequency domain by a fast Fourier transform function. Frequency spectrum amplitude data is then converted to a log-log scale thereby revealing a pattern of spectrum amplitudes indicative of pit initiation rates.

A material and process for providing a corrosion inhibitor cationic film on he exterior aluminum surface of a weapon when contained in a submarine launch tube. An effervescent tablet containing a corrosion inhibitor material is disposed within the launch tube with the weapon and, upon flooding of the launch tube with seawater, the effervescent tablet releases the corrosion inhibitor material into the water to form a solution that coats the exposed aluminum surfaces of the weapon with a cation film of the corrosion inhibitor material.

A self-contained, expendable sea-state measuring device which deeply submed submarines can launch in order to determine sea surface conditions prior to a missle launch. The device comprises a multi-chambered, buoyant cylindrical metal shell which houses a sea-state measuring instrumentation package, a moment correcting counterwieght, a long data downlink with spooling means and a bouyant lifting body which 'flies' the data wire away from the launch platform. The buoy is launched from the submarine via the aft signal ejector, buoyantly ascends to the surface, and then transmits sea surface information back to the submarine via the data link.
