The scleral search coil can be used to assess the vestibulo-ocular reflex.
2.
Additionally, a second search coil can be added to measure torsional rotation.
3.
A two axis magnetic search coil antenna measured AC magnetic fields.
4.
The prototype NQR devices resemble metal detectors _ waist-high poles with search coils at the base.
5.
Their system motorized the search coil as well as a circular display card, which rotated in sync.
6.
For table-mounted systems, such as search coils, head direction is subtracted from gaze direction to determine eye-in-head position.
7.
It is associated to a conditioning electronic to make a search coil magnetometer ( also known as induction magnetometer ).
8.
The TDSF receiver has little to no gain below about ~ 120 Hz and the search coil magnetometers roll off around ~ 3.3 Hz.
9.
Each magnet generates a field using a different frequency, allowing the readings from the search coil to be analyzed by computer to determine displacement in multiple dimensions.
10.
A single magnetometer was oriented along the plane perpendicular to the spin axis of the spacecraft . Search coil magnetometers have become increasingly more common in Earth observation satellites.
