KAT was founded in 1979 by guitarist Piotr Luczyk and drummer Ireneusz Loth. Shortly after they were joined by bassist Tomasz Jaguś and another guitarist, Ryszard Pisarski. They played instrumental music influenced by hard rock bands, mainly Deep Purple, Led Zeppelin, and Black Sabbath. In 1981, during the first edition of the Silesian Rock festival, the band found a singer, Roman Kostrzewski The line-up was filled out by guitarist Wojciech Mrowiec and in 1984 KAT released the debut single "Noce szatana / Ostatni tabor" (Polish for The Nights of Satan / The Last Train). Robert "Lor" Milewski wrote the lyrics of both songs; since then Kostrzewski became the lyricist, incorporating poetry, Polish folklore, and mysticism. The band also toured with Hanoi Rocks.

KAT-7

KAT-7 is a radio telescope constructed in the Northern Cape of South Africa. Part of the Karoo Array Telescope project, it is the precursor engineering test bed to the larger MeerKAT telescope, but it has become a science instrument in its own right. The construction was completed in 2011 and commissioned in 2012. It also served as a technology demonstrator for South Africa's bid to host the Square Kilometre Array. KAT-7 is the first Radio telescope to be built with a composite reflector and uses a stirling pump for 75 K cryogenic cooling. The telescope was built to test various system for the MeerKAT array, from the ROACH correlators designed and manufactured in Cape Town, now used by various telescopes internationally, to composite construction techniques. With the short baselines the telescope is suited to observing diffuse sources, but will begin VLBI observation in 2013.

Technical Specifications

KAT-7 consist of 7 dishes of 12 metres in diameter each a Prime Focus Reflecting telescope.

Kat-5 (vehicle)

Kat-5 is an autonomous vehicle created by Team Gray, an organization comprising employees from The Gray Insurance Company and students from Tulane University's School of Engineering, for the 2005 DARPA Grand Challenge.

The vehicle

Kat-5 is a 2005 Ford Escape Hybrid modified with the sensors and actuators needed for autonomous operation. It has an INS/GPS (Inertial Navigation System/Global Positioning System) from Oxford Technical Solutions and LIDAR units from SICK and Riegl. Kat-5 finished the 2005 DARPA Grand Challenge and placed fourth with a time of 7 hours, 30 minutes, only 37 minutes behind Stanley, the winner of the competition. Kat-5 is powered by almost 100% pure Java and runs both the Mac OS X and Linux operating systems.

Kat-5 uses oscillating LIDARs and information from the INS/GPS unit to create a picture of the surrounding environment. This information is then used to build a path for the vehicle to follow. Kat-5's primary electrical system, used to run the computers and drive-by-wire system, is powered by the standard electrical system of the vehicle while the 24-volt system, used to power the LIDAR sensors, is powered by six solar panels on the roof platform of the vehicle.
