Maintaining air supremacy soon may be easier for U.S. fighter pilots equipped with the latest helmet technology. Head-tracking display screens are being designed to allow target designation with little more than a pilot's nod. The introduction at the end of the 1980s of the Soviet AA-11 Archer air-to-air missile revealed a serious deficiency in U.S. capabilities. That deficiency took on increasingly ominous significance as Russian-built aircraft and air-launched weapons, integrated with helmet-mounted sights and capable of being launched at up to 90 degrees off boresight of a target, proliferated widely to governments hostile to the United States. The problem is now being addressed in a joint U.S. Navy-U.S. Air Force effort, which combines the AIM-9X missile, an advanced short-range dogfight weapon with a targeting device that can aim sensors and weapons wherever a pilot looks.

Two new types of flat screen displays are now being used in rugged military and commercial applications. The first type, which was designed for use on U.S. Army field generators, is an intelligent display screen that employs an innovative "transflective" design. This allows information to be easily read in both bright sunlight and darkness while requiring unusually low power inputs to operate.

New very high frequency radios are sharing the airwaves with sensor systems in battlefield networking. Both communications and radar units have become portable enough that they now are mobile nodes in an interlocking information web.

A simulation tool that creates a virtual satellite allows ground personnel to rehearse satellite communications and operations disciplines without tying up valuable orbiters. The new system enables warfighters to train on, assess and certify orbital communications links without interrupting ongoing satellite operations.

Semiconductor designers are increasing their dependence on computer-aided design and testing to advance microcircuitry beyond the current state of the art. Demand for more and more complex chips has necessitated taking design out of the hands of engineers and into the realm of cyberspace.

As Alvin Toffler predicted almost 30 years ago, society is transitioning from its second wave, the industrial revolution, to the third wave, the information age. All three waves, beginning with the agrarian age, offered their own elements of control that proved vital to prevailing economically and politically. In the first wave, the objective in the agrarian society was to control the land from which life-giving food would be harvested. In the industrial second wave, the objective was to control the means of production. Now, in the information age, the objective is to control the information technology.

Data visualization, where information is displayed in recognizable graphic elements, increasingly is moving into mainstream applications as a remedy for information overload. As computer users find growing amounts of gigabytes at their fingertips, system engineers are returning display perspectives to everyday three-dimensional visages that are comprehended faster and more readily.

Organizations that rely on large amounts of data are increasingly employing data cleansing techniques to ensure accuracy and efficiency by scrubbing data that has been polluted at the source or on its way to a data warehouse.

Federal agencies with specialized image archival requirements are meeting their storage and retrieval needs by maximizing the capabilities of software first used by Hollywood's entertainment industry. Government organizations with large image databases can use this software, which employs innovative search techniques, to help analysts sift through incalculable amounts of digital information. The software eliminates typical problems involved in tracking important reference material and can assist agencies by also housing information gathered from analysis of image files.

The Internal Revenue Service is adopting a mission-oriented approach to designing its new agencywide information infrastructure. Instead of focusing on information technology, the modernized system will be business-centered to ensure that it directly addresses the agency's requirement to manage mountains of data while collecting over $1 trillion in annual tax revenues.
