Effect of Vagus Nerve Stimulator Magnet on Programmable Shunt Settings

Neurosurgery, 2004
Vagus nerve stimulators and programmable shunt valves are used in the operative care of epilepsy and hydrocephalus, respectively. Both devices use magnetic fields to activate and program their various settings and functions. The authors conducted several ex vivo trials to better elucidate any interplay between the two systems.A pulse generator ...

Ion Extraction From Magnetically Driven Carbon Shunting Arc Plasma

IEEE Transactions on Plasma Science, 2006
Shunting arc discharge is a pulsed plasma source of metals and semimetal materials and is ignited without any trigger sources at a wide range of gas pressures, from vacuum to atmospheric pressure under identical discharge conditions. In this paper, an ion extraction from magnetically driven carbon shunting arc discharge and a criterion of the arc ...

Surface mount shunt capacitor filters using bilateral magnetic coupling

2017 IEEE International Symposium on Electromagnetic Compatibility & Signal/Power Integrity (EMCSI), 2017
This paper proposes shunt capacitor filters using magnetic coupling which improves the filter performance. The proposed filter structure is designed to place input/output paths parallel to shunt path from a power supply line to a ground plane. And magnetic couplings between the input/output paths and shunt path are utilized to reduce parasitic ...

Theoretical treatment of internal shunt protection for superconducting magnets

Journal of Physics E: Scientific Instruments, 1971
Considers the theory of internal protective shunts and switches used to limit the maximum temperature rise when a large high-current density superconducting magnet quenches, whilst operating in the persistent mode. The shunts can induce more even heating and dissipation, thus avoiding hotspots.
