Abstract
A system for use in classifying a vehicle includes a capacitive sensor for operatively receiving a weight of a vehicle and a capacitance detector coupled to said capacitive sensor. The capacitance detector is adapted to determine a capacitance signal of the capacitive sensor in response to the capacitive sensor operatively receiving the weight of the vehicle.
Claims48
A system for use in classifying a vehicle, said system comprising:
- a capacitive sensor for operatively receiving a weight of a vehicle;
- and
- a capacitance detector coupled to said capacitive sensor, said capacitance detector adapted to determine to a capacitance signal of said capacitive sensor in response to said capacitive sensor receiving the weight.
A method for use in classifying a vehicle, the method comprising:
- receiving the vehicle on a surface of a capacitive sensor;
- and
- determining a capacitance signal in response to the vehicle being received on the surface of the capacitive sensor.
A system for a use in classifying a vehicle, said system comprising:
- a treadle having a first cavity and a second cavity;
- a first conductive strip insulated from a second conductive strip, said first conductive strip and said second conductive strip being located in said first cavity and being coupled to a capacitance detector;
- a third conductive strip and a fourth conductive strip located in said second cavity.
