Abstract
In one example, we describe a method and system for tables, beds, chairs, cabinets, bags, boxes, or appliances, to find the weight of an object or human conveniently and reliably, using Z-casters. Z-caster is based on Z-numbers, which is a pair of (A,B), where A is the value of the weight (based on and expressed as a Fuzzy parameter/value), and B is the reliability for that (expressed here as a Z-number). The calibration method is also described. Each basic unit has 2 types of sensors: for coarse measurement (just as a switch, with a rough/Fuzzy threshold) and for fine measurement. Many variations, examples, applications, and materials are shown here.
