Enhanced armor

Article Abstract:

One of the least apparent recent improvements in armor has been the development of new, ultrahigh-hardness steels which are as much as 20 percent harder than the hardest off-the-shelf high-carbon steels, but they tend to be brittle and can crack when hit. Armor Holdings has introduced an optimized version called UH56 steel, which is hard enough to fracture armor-piercing ammo, but tough enough not to crack with many impacts and is also easier to shape.

Cognitive radio

Article Abstract:

Latest cognitive radios and other new wireless devices avoid transmission constrictions by switching instantly to nearby frequencies that they sense are clear. Adaptive software enables these intelligent devices to reconfigure their functions to meet the demands of communications networks and the new flexibility afforded by cognitive radio might enable consumers to take advantage of cheaper wireless network paths available locally to make calls.
