The effect of scleral search coil lens wear on the eye [PDF]
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 ...

A Low-cost Electromagnetic Docking Guidance System for Micro Autonomous Underwater Vehicles
As important observational platforms for the Smart Ocean concept, autonomous underwater vehicles (AUVs) that perform long-term observation in fleets are beneficial because they provide large-scale sampling data with a sufficient spatiotemporal resolution.

Measurement of Sudden Displacements in Superconducting Coils using Search-coils
Search-coils, which can detect magnetic field variations, have been applied to the measurement of superconducting coil displacements. The advantage of the search-coil is that it can measure displacements which occur in an arbitrary section of a superconducting coil without making contact with a winding.

Inductive localization accuracy of a passive 3-D coil in an Industry 4.0 environment [PDF]
In this paper a localization system of a passive 3-D coil is proposed and signal uncertainties due to the 3-D coil's arbitrary orientation are analyzed. The 3-D coil is excited by an alternating primary magnetic field.

Routine phasing of coiled-coil protein crystal structures with AMPLE
Coiled-coil protein folds are among the most abundant in nature. These folds consist of long wound α-helices and are architecturally simple, but paradoxically their crystallographic structures are notoriously difficult to solve with molecular-replacement
