Abstract
A system and method for processing sensor signals is disclosed. The system comprises a sensor array, a multiplexer, a converter, a selection module and a combination module. The sensor array measures a physical parameter in a first dimension on a seat and generates a first set of sensor signals. The sensor array measures the physical parameter in a second dimension on the seat and generates a second set of sensor signals. The multiplexer multiplexes the first set of sensor signals into a first signal stream and the second set of sensor signals into a second signal stream. The converter converts the first signal stream to a first set of digital signals and the second signal stream to a second set of digital signals. The selection module determines a set of first-dimension data and a set of second-dimension data. The combination module forms a set of two-dimensional data.
