摘要： A vehicle proximity sensor system comprising: a magnetometer; and a controller configured to: receive a reference magnetic field signal from the magnetometer; receive a measurement magnetic field signal from the magnetometer; determine magnetic field displacement data based on the measurement magnetic field signal and the reference magnetic field signal; and signal the presence of a vehicle based on the magnetic field displacement data.

摘要： A damage detection system, comprising: an elongate structure, wherein the elongate structure comprises a safety structure or a racking limb; a radiation emitter configured to emit a radiation signal internally to, and along a length of, the elongate structure; a radiation sensor configured to receive the radiation signal and output a sensing signal in response; and a controller configured to: receive the sensing signal from the radiation sensor; determine a damage status of the elongate structure based on the sensing signal; and output a damage signal representative of the damage status.

摘要： A damage detection system for monitoring a magnetised structure for damage comprising: a magnetometer; and a controller configured to: receive a first magnetic field signal of the magnetised structure from the magnetometer; receive a second magnetic field signal of the magnetised structure from the magnetometer; determine magnetic field displacement data based on the second magnetic field signal and the first magnetic field signal; and determine a condition of the magnetised structure based on the magnetic field displacement data.
