  • Method and apparatus for continuously detecting the presence of vehicles, with an optical sensor and a magnetic sensor
    Patent number: 8803708
    Abstract: A method and apparatus for continuous, non-intermittent, detection of vehicles based on a light detector for detecting a change in illumination when a vehicle arrives or departs, and on a use of the light detection to activate a magnetic sensor, a sensitivity of which is adjusted to detect only those magnetic disturbances sufficiently large to be able to be attributed to a vehicle which is over the sensor. Both the light detector and the magnetic sensor are connected directly to a digital controller without a need for active electronic components or their own or a shared power supply source. The light detector may be fixed or portable, wireless or connected by cables, and may operate independently or as part of a sensor network.
