Abstract:
1. A method for sensing an object with a plurality of conductors, wherein the object is capable of changing one or more characteristics of each of said conductors, the method comprising: (a) selecting conductors from said plurality of conductors and coupling the selected conductors to one or more first circuits to place the selected conductors into states indicative of the one or more characteristics of the selected conductors; (b) after coupling the selected conductors to the one or more first circuits, coupling the selected conductors to one or more first node to develop first signals on the one or more first nodes, the first signals being indicatibe of the one or more characteristics of the selected coductors; and (c) deselecting the conductors to select other conductors for coupling to the one or more first nodes and the one or more first circuits, wherein the deselected conductors are not coupled to the one or more first circuits and the one or more first nodes; wherein for at least a first conductor and a second conductor which are two of said conductors, a time period when the first conductor is coupled to at least one of the one or more first nodes overlaps with a time period when the second conductor to at least one of the one or more first circuits.
