The thyristor is a four-layered, three terminal semiconductor device, with each layer consisting of alternately N-type or P-type material, for example P-N-P-N.n earlier gas filled tube device called a thyratron provided a similar electronic switching capability, where a small control voltage could switch a large current. It is from a combination of thyratron and  transistor  that the term thyristor is derived.
A ventriculoperitoneal (VP) shunt is a medical device that relieves pressure on the brain caused by fluid accumulation. VP shunting is a surgical procedure that primarily treats a condition called hydrocephalus.This condition occurs when excess cerebrospinal fluid (CSF) collects in the brainâs ventricles.hen this normal flow is disrupted, the buildup of fluid can create harmful pressure on the brainâs tissues, which can damage the brain. Doctors surgically place VP shunts inside one of the brainâs ventricles to divert fluid away from the brain and restore normal flow and absorption of CSF.
