Abstract: Information transfer is effected using a network of electrical signal conductors and sensors forming crosspoint connections. The sensors are capable of representing a measurement parameter as an electrical impedance. One embodiment of the present invention includes output electrical conductors, input electrical conductors, and sensors. Each of the sensors is connected with one of the output electrical conductors and one of the input electrical conductors so as to form an array of crosspoint connections. Application of electrical signals to the sensors and measurement of electrical signals from the sensors provide sufficient information to derive relative information corrected for parasitic current sources for each sensor using algorithms based on equations for combining impedance. The embodiment may further include one or more reference elements connected with the output electrical conductors and with the input electrical conductors so as to form crosspoint connections.
