Claim One:
1. A system for detecting the presence of a human in a vehicle, the system comprising: a vibration sensor configured to detect vibrations of the vehicle and to output signals related to the sensed vibrations; a processor configured to receive the signals output from the vibration sensor; and a neural network run by the processor and having plurality of nodes, at least one of the nodes being a recurrent node, thereby facilitating operation of the neural network using a time delay between an output from a recurrent node and an input, of the recurrent node output, into another of the nodes, and using a time delay between the recurrent node output and an input, of the recurrent node output, back into the recurrent node, the neural network being configured to provide at least one output value indicating that a human is present in the vehicle and at least one output value indicating that a human is not present in the vehicle.
