First Results of the THEMIS Search Coil Magnetometers [PDF]
Space Science Reviews, 2008 We present the first data from the THEMIS Search Coil Magnetometers (SCM), taken between March and June 2007 while the THEMIS constellation apogee moved from the duskside toward the dawnside. Data reduction, especially the SCM calibration method and spurious noise reduction process, is described.

The effect of scleral search coil lens wear on the eye [PDF]
British Journal of Ophthalmology, 2001 Scleral search coils are used to measure eye movements. A recent abstract suggests that the coil can affect the eye by decreasing visual acuity, increasing intraocular pressure, and damaging the corneal and conjunctival surface. Such findings, if repeated in all subjects, would cast doubt on the credibility of the search coil as a reliable ...

An integrated CMOS micro search‑coil magnetometer with on‑chip calibration and a low‑noise amplifier [PDF]
Microsystems & NanoengineeringThis paper presents a fully CMOS‑integrated micro search‑coil magnetometer (µSCM) that achieves a NEMI of 2.1 nT/√Hz at 1 kHz while consuming only 364 µW, approximately a tenfold improvement over previous CMOS search‑coil magnetometers (SCMs). The system

A preformed scleral search coil for measuring mouse eye movements. [PDF]
J Neurosci Methods, 2010 Mice are excellent subjects for use of genetic-manipulation techniques to study the basis of pathological and normal physiology and behavior; however behavioral analyses of associated phenotypes is often limited. To improve the accuracy and specificity of repeated measurements of vestibular function, we developed a miniaturized, contact-lens scleral ...

Optimal coil orientation for transcranial magnetic stimulation. [PDF]
PLoS ONE, 2013 We study the impact of coil orientation on the motor threshold (MT) and present an optimal coil orientation for stimulation of the foot. The result can be compared to results of models that predict this orientation from electrodynamic properties of the ...
