A method and apparatus for processing satellite positioning system signals which are weak in level. The complementary current mode logic driver circuit provides a first output voltage and a second output voltage. The variables in another table include additional geographic variables, structural characteristics, amount of insurance and provides controls for managing deductibles. LC tanks are then placed and sized in the VLSI clock grid to implement a resonant tank clock grid and the input grid buffer is resized. The lens-retention mechanism comprises a post and detent, while the adjustment mechanism comprises various mechanisms, for example a rack and pinion, a lever or a rack and pawl that biases the lens to one of the other positions. In one example, the device includes an internal paint reservoir, an internally fed paint applicator configured to apply a liquid coating of paint to a surface, and a pump assembly configured to draw paint from the internal paint reservoir and pump the paint to the paint applicator.
