Patent abstract

A module and method for determining whether a seat is empty. In one embodiment, the module includes a projection module that is configured to receive force data that includes a plurality of modes. The projection module is also configured to isolate data for one of the modes. A transform module is configured to communicate with the projection module, and to transform the data for one of the modes into a frequency domain, thus generating spectral mode data. In addition, a spectral analysis module is configured to communicate with the transform module, and to classify the spectral mode data.
