Signal Processing System

A system for processing sensor signals, the system comprising:

• a sensor array measuring one or more physical parameters in a first dimension on a seat and generating a first set of sensor signals for the first dimension, the sensor array measuring the one or more physical parameters in a second dimension on the seat and generating a second set of sensor signals for the second dimension;
• a multiplexer communicatively coupled to the sensor array, the multiplexer multiplexing the first set of sensor signals into a first signal stream and the second set of sensor signals into a second signal stream;
• a converter communicatively coupled to the multiplexer, the converter converting the first signal stream to a first set of digital signals and the second signal stream to a second set of digital signals;
• a selection module communicatively coupled to the converter, the selection module determining a set of first-dimension data from the first set of digital signals and a set of second-dimension data from the second set of digital signals;
• and
• a combination module communicatively coupled to the selection module, the combination module combining the set of first-dimension data and the set of second-dimension data to form a set of two-dimensional data.

A computer program product comprising a non-transitory computer readable medium encoding instructions that, in response to execution by a computing device, cause the computing device to perform operations comprising:

• multiplexing a first set of sensor signals into a first signal stream and a second set of sensor signals into a second signal stream, the first set of sensor signals representing one or more measurements for one or more physical parameters in a first dimension on a seat, the second set of sensor signals representing one or more measurements for the one or more physical parameters in a second dimension on the seat;
• converting the first signal stream to a first set of digital signals and the second signal stream to a second set of digital signals;
• determining a set of first-dimension data from the first set of digital signals and a set of second-dimension data from the second set of digital signals;
• and
• combining the set of first-dimension data and the set of second-dimension data to form a set of two-dimensional data.
