1. An occupant detection system comprising:

  • at least one sensing device disposed in a seat, wherein the sensing device is configured to detect signals at an operating frequency;

    an electronic device configured to acquire data from the at least one sensing device, wherein the data is indicative of a signal value at the operating frequency, wherein the electronic device acquires a first set of data and a second set of data during a first time period and second time period distinct from the first time period, each set of data comprising data acquired in at least two sensing device configurations characterized as detecting signals at distinct operating frequencies, wherein the first set of data and second set of data are compared to each other to create a set of change data having an individual element for each operating frequency; and

    a heuristic configured to determine anomalous acquired data by comparing the individual elements for each operating frequency within the set of change data to each other.
