This technology may produce a magnetic sensor that has all of its input and output signals in the form of light on fiber-optic cables.

It detects and records the electromagnetic signals that are associated with the heartbeat using a multi channel magnetic sensor array.

In order to do so, a magnetic sensor records a subject's head movements and images that show the eyes' exact viewpoint 120 times per second.

When a vehicle approaches, vibrations travelling through the ground trigger the seismic sensor, which activates the magnetic sensor.

A magnetic sensor located several inches away with its sensitive axis parallel to the direction of travel can detect the remnant field of the ink particles.
