Weight sensors are electrical devices that can be used to determine the pressure on a surface. This technology works, but has proven to be expensive to implement. SR is designing their own technology, which will be integrated to the panel design upon its completion. Adding these sensors to SR panels essentially turns each panel into a type of scale. They can sense objects of (or above) a certain weight on the surface of the panel and the microprocessors can take any programmed action; this can warn drivers of potential hazards in the road.
I had a pretty strong idea of the traits of the various aliens. I knew the Cara’ot were master traders, and genetic engineers. I knew the Isanjo were functionally high steel workers, the Flutes are highly skilled in mathematics. Truthfully I cheated a bit though I’m going to have to address this in book four since I have an alien view point character. Because the aliens are a conquered people their own religions, cultural norms, etc. have been suppressed by their human rulers. Most of them claim to worship human gods, particularly the Christian god, they don’t have to accept the limits female participation in business because they are considered less than, but in most ways they try to ape their conquerors. It’s just safer that way.
