Systems and techniques are described which improve performance, reliability, and predictability of networks without having costly hardware upgrades or replacement of existing network equipment. The canopy cover being adapted to pivotally attach to the golf cart side walls located behind the seat back of the cart. The cover glass can not move easily from the correct position because the wall portions serve as supporting columns, thereby improving the yield. The flare cells have a substantially greater elongation ratio than the body cells. The laminated layers each include a magnetic layer and a non-magnetic spacer layer. In the enhancement, portions of the image having a measured roughness within a certain range are artificially increased in roughness.
