Application Note: Shortwave Infrared (SWIR) Imaging Aids Laser Tracking, Detection
3/28/2007
As warfare becomes more asymmetric, civilians and other non-combatants become a larger percentage of the casualties, along with unintended property damage. The military, of course, hopes to avoid these types of casualties and destruction. With advancing technologies that enable more precision from their weapons, they also need better pointing and targeting capabilities, while remaining covert

Power Is Not Dependent On Dimensions
6/23/2005
Speaking about micromotors, "Small, compact, powerful" is not only a slogan but a hard fact of life and reality. Despite miniaturisation, it is therefore possible to maintain or even increase a motor's performance making extensive use of new materials and technologies. In this context, DC-micromotors with permanent magnets play an important role
